An administrator has deployed a new virtual machine on an ESXi 5.x host. Users are complaining
of poor performance on the application running on the virtual machine. Performance tools display
the results shown in the exhibit.
Which two tasks might improve the user experience? (Choose two.)
Correct Answer(s)
A. A. Add a vCPU to the virtual machine
D. D. Remove the limit on the CPU settings of the virtual machine
Explanation
The exhibit shows that the CPU usage is consistently high, reaching 100% at times. This indicates that the virtual machine is experiencing a CPU bottleneck, which is causing the poor performance. Adding a vCPU to the virtual machine can help distribute the workload across multiple CPUs, improving performance. Additionally, removing the limit on the CPU settings of the virtual machine will allow it to utilize more CPU resources, further improving performance.
2.
An administrator notices that when a virtual machine is placed into a resource pool, a warning
indicates that the virtual machine will receive a very large percentage of the total shares for
memory. Which action can be taken to resolve this problem?
Correct Answer
D. D. Decrease the memory allocation for the virtual machine.
3.
An administrator views the Fault Tolerance pane of the Summary tab of a virtual machine and
finds that the current status is Not Protected.
What are two vSphere Fault Tolerance states that would cause the virtual machine to not be
protected? (Choose two.)
Correct Answer(s)
B. B. Need Secondary VM - The primary virtual machine is running without a secondary virtual
machine and is not protected
D. D. Disabled - Fault Tolerance is disabled.
Explanation
The correct answers are B and D. If the Fault Tolerance status is "Need Secondary VM," it means that the primary virtual machine is running without a secondary virtual machine, which makes it unprotected. If the Fault Tolerance status is "Disabled," it means that Fault Tolerance is disabled for the virtual machine, also making it unprotected.
4.
Which two conditions prevent the application of a host profile to an ESXi 5.x host? (Choose two.)
Correct Answer(s)
B. B. The host has not been placed into maintenance mode.
C. C. The host is running virtual machines
Explanation
The host must be placed into maintenance mode before applying a host profile to prevent any disruptions to the running virtual machines. If the host is not in maintenance mode, the profile cannot be applied. Additionally, if the host is running virtual machines, applying a host profile may cause disruptions to the virtual machines, so the profile cannot be applied in this case as well.
5.
An administrator is editing the IP allocation policy for a vApp.
Which three options are available? (Choose three.)
Correct Answer(s)
C. C. Transient
D. D. DHCP
E. E. Fixed
Explanation
The administrator has the option to choose between three IP allocation policies for the vApp: Transient, DHCP, and Fixed. The Transient option means that IP addresses are allocated to virtual machines within the vApp dynamically, and they can change each time the vApp is powered on. The DHCP option allows the use of a DHCP server to allocate IP addresses to the virtual machines. The Fixed option means that IP addresses are manually assigned to the virtual machines and remain the same even when the vApp is powered off and on again.

ACME Junkmail Incorporated has been utilizing templates in their environment. They are running
a 10-node ESXi 5.x Cluster and DRS has not been configured. Several virtual machines have
been deployed from this template and successfully powered on, but a newly deployed virtual
machine will not power on. There appear to be adequate CPU and Memory resources available on
the host.
Which three things can be done to allow more virtual machines to be deployed into the cluster
from this template? (Choose three.)
Correct Answer(s)
A. A. Select a different datastore for the virtual machine
B. B. Move the swap file to a different location
E. E. Increase the virtual machine memory reservation
Explanation
If you make reservations for your virtual machine’s that are equal to the amount of RAM assigned
to them, swapping and page sharing does not occur. You can over commit pretty heavily if you are
comfortable with poorer performance. If you do not set reservations, ESX host creates a .vswp file
equal to the difference between the amount of physical memory assigned to the virtual machine
and the reservation it has. By default, memory reservations are set to 0. If you have a virtual
machine with 2GB of memory without a reservation, it creates a 2GB .vswp file when it is powered
on. The virtual machine starts using the .vswp file if the server is out of physical RAM. If you set a
1GB reservation, it creates a 1GB .vswp file. The .vswp files are what allows for memory
overcommitment.

What are three valid objects to place in a vApp? (Choose three.)
Correct Answer(s)
C. C. Resource pools
D. D. vApps
E. E. Virtual machines
Explanation
The question is asking for three valid objects that can be placed in a vApp. A vApp is a container for virtual machines and other vApp templates. Resource pools are used to allocate resources to virtual machines, so they can be placed in a vApp. vApps themselves can also be placed in a vApp, allowing for nested vApps. Finally, virtual machines are the main components of a vApp, so they can also be placed in a vApp. Therefore, the correct answers are C. Resource pools, D. vApps, and E. Virtual machines.
8.
Which three Storage I/O Control conditions might trigger the Non-VI workload detected on the
datastore alarm? (Choose three.)
Correct Answer(s)
A. A. The datastore is connected to an ESX/ESXi 4.0 host that does not support Storage I/O Control.
B. B. The datastore is on an array that is performing system tasks such as replication.
E. E. The datastore is connected to an ESX/ESXi 4.0 host that is not managed by vCenter.
Explanation
The Non-VI workload detected on the datastore alarm can be triggered by three conditions. Firstly, if the datastore is connected to an ESX/ESXi 4.0 host that does not support Storage I/O Control. Secondly, if the datastore is on an array that is performing system tasks such as replication. Lastly, if the datastore is connected to an ESX/ESXi 4.0 host that is not managed by vCenter.
9.
An administrator has just finished deploying a vApp for a web service.
What three options are available to the administrator for IP allocation within the vApp? (Choose
three.)
Correct Answer(s)
A. A. Transient
B. B. Fixed
C. C. DHCP
Explanation
The administrator has three options for IP allocation within the vApp: Transient, Fixed, and DHCP.
- Transient IP allocation means that the IP address is assigned dynamically and can change each time the vApp is powered on or off. This is useful for temporary or short-term deployments.
- Fixed IP allocation means that the IP address is manually assigned and remains constant even if the vApp is powered on or off. This is useful for long-term or permanent deployments.
- DHCP IP allocation means that the IP addresses are assigned by a DHCP server within the network. This is useful for automatically assigning and managing IP addresses in a large-scale deployment.
These options provide flexibility and control over IP allocation within the vApp.
10.
An administrator is working to implement Storage Profiles in their environment.
Which two ways can storage capabilities be generated? (Choose two.)
Correct Answer(s)
C. C. They can be retrieved from the array through the VMware APIs for Storage Awareness (VASA).
D. D. They can be manually generated by the administrator.
Explanation
Storage capabilities can be generated in two ways. Firstly, they can be retrieved from the array through the VMware APIs for Storage Awareness (VASA). This allows the administrator to gather information about the storage capabilities directly from the storage array. Secondly, the administrator can manually generate the storage capabilities. This means that the administrator can manually define and configure the storage capabilities based on their specific requirements and environment.
11.
Which VMware solution uses the security of a vSphere implementation and provides linked-clone
technology to virtual desktops?
Correct Answer
B. B. VMware View
Explanation
VMware View is the correct answer because it is a VMware solution that utilizes the security features of vSphere and offers linked-clone technology to virtual desktops. VMware ACE is not the correct answer as it is a separate product that provides secure remote access to virtual machines. VMware Workstation is a desktop virtualization solution for running multiple operating systems on a single machine, and VMware ThinApp is a tool for virtualizing applications.
12.
Which two conditions will prevent a virtual machine from being successfully migrated using
Storage vMotion? (Choose two.)
Correct Answer(s)
B. B. The virtual machine has Fault Tolerance enabled.
C. C. The virtual machine is running on a vSpHere 5.x Standard host.
Explanation
Storage vMotion is a feature in VMware vSphere that allows the migration of a virtual machine's storage from one datastore to another while the virtual machine is running. However, there are certain conditions that can prevent a virtual machine from being successfully migrated using Storage vMotion. One of these conditions is when the virtual machine has Fault Tolerance enabled. Fault Tolerance is a feature in VMware vSphere that provides continuous availability for virtual machines by creating a secondary copy of the virtual machine on another host. This secondary copy cannot be migrated using Storage vMotion. Another condition that can prevent a virtual machine from being migrated using Storage vMotion is when the virtual machine is running on a vSphere 5.x Standard host. Storage vMotion requires the use of vSphere Enterprise or Enterprise Plus licenses. Additionally, having an RDM (Raw Device Mapping) or a disk stored on an NFS (Network File System) datastore does not prevent a virtual machine from being migrated using Storage vMotion.
13.
Under which two conditions can vStorage APIs for Array Integration (VAAI) provide a performance
benefit? (Choose two.)
Correct Answer(s)
A. A. When a virtual disk has VMDK files stored on an NFS datastore.
D. D. When a virtual disk is deleted.
Explanation
VAAI can provide a performance benefit when a virtual disk has VMDK files stored on an NFS datastore because it offloads certain storage operations to the storage array, reducing the workload on the ESXi host. Additionally, VAAI can also provide a performance benefit when a virtual disk is deleted because it allows the storage array to reclaim the space previously used by the virtual disk more efficiently.
14.
An administrator is enabling Enhanced vMotion Compatibility (EVC) in a DRS cluster. The
administrator wants only hosts with the newest Intel processors added to the cluster.
Which setting satisfies this requirement?
Correct Answer
D. D. Create a new baseline and add only the latest processor family
Explanation
The correct answer is D. Create a new baseline and add only the latest processor family. This setting allows the administrator to create a new baseline specifically for the newest Intel processors. By adding only the latest processor family to the baseline, the administrator ensures that only hosts with the newest Intel processors will be added to the cluster. This satisfies the requirement of only including hosts with the newest Intel processors.
15.
Which two conditions must exist on all hosts in the cluster if Enhanced vMotion Compatibility
(EVC) is used? (Choose two.)
Correct Answer(s)
B. B. All hosts in the cluster must be running ESX/ESXi 3.5 Update 2 or later.
C. C. All hosts in the cluster must have hardware virtualization support enabled.
Explanation
For Enhanced vMotion Compatibility (EVC) to be used, two conditions must exist on all hosts in the cluster. Firstly, all hosts in the cluster must be running ESX/ESXi 3.5 Update 2 or later. This ensures that the necessary software compatibility is met. Secondly, all hosts in the cluster must have hardware virtualization support enabled. This ensures that the hardware is capable of supporting virtualization. Therefore, options B and C are the correct answers.
16.
Users are experiencing performance issues when updating their database hosted on a virtual
machine. The administrator determines that disk I/O is high across one of the HBAs on the ESXi
host containing the virtual machine.
What is the action will most likely correct the issue without significantly impacting other users or
datastores?
Correct Answer
A. A. Manually configure the disk multipathing policy to Round Robin for the datastore
Explanation
By manually configuring the disk multipathing policy to Round Robin for the datastore, the administrator can distribute the I/O load across multiple paths, reducing the strain on a single HBA. This can help improve performance without significantly impacting other users or datastores. Migrating the virtual machine to a different datastore or mapping additional LUNs may not directly address the high disk I/O issue.
17.
An administrator takes a vSphere snapshot of a virtual machine and applies an OS update. After
confirming the update the administrator cannot enable Fault Tolerance on the virtual machine and
suspects there are snapshots that have not been consolidated.
Which two operations can the administrator perform to verify consolidation is needed? (Choose
two.)
Correct Answer(s)
A. A. Expose the Needs Consolidation column in the virtual machines tab of the host.
B. B. Browse the datastore containing the vmdk files and look for files with the "-delta.vmdk"
extension.
Explanation
To verify if consolidation is needed, the administrator can perform two operations. First, they can expose the Needs Consolidation column in the virtual machines tab of the host. This column will show if any virtual machines require consolidation. Second, they can browse the datastore containing the vmdk files and look for files with the "-delta.vmdk" extension. These files indicate that there are snapshots that have not been consolidated. By performing these two operations, the administrator can confirm if consolidation is needed.
18.
An administrator has created a virtual machine that will be accessed from a public kiosk.
Management has requested that the virtual machine be reset to a known state once a week or on
demand if requested.
Which method is the simplest way to meet this requirement?
Correct Answer
C. C. Set the VMDKs of the virtual machine to be Independent-Nonpersistent and schedule restarts
of the virtual machine.
Explanation
Setting the VMDKs of the virtual machine to be Independent-Nonpersistent allows any changes made to the virtual machine to be discarded upon restart. This ensures that the virtual machine always starts in a known state. By scheduling regular restarts of the virtual machine, either once a week or on demand, the requirement of resetting the virtual machine to a known state is met. This method is the simplest because it does not require any additional hardware or software, such as a storage array or imaging server.
19.
What are three true statements about quiescing virtual machine snapshots? (Choose three.)
Correct Answer(s)
C. C. The quiescing operation varies by guest OS.
D. D. Quiescing should occur before array-based snapshots to ensure consistency.
E. E. VMware Tools is required for quiescing to be successful
Explanation
The correct answer is C, D, and E. The quiescing operation varies by guest OS, meaning that different operating systems may have different methods of quiescing virtual machine snapshots. Quiescing should occur before array-based snapshots to ensure consistency, as it allows for the proper freezing of the file system and applications to create a stable snapshot. VMware Tools is required for quiescing to be successful, as it provides the necessary drivers and services for the virtual machine to communicate with the host and properly quiesce the snapshot.
20.
An administrator has deployed vCenter Data Recovery and wants the largest possible deduplication
store. Which three storage options can be used? (Choose three.)
Correct Answer(s)
B. B. Two RDMs on a FCP array
C. C. One NFS mount on the ESXi host and one RDMs on an iSCSI array
E. E. Two NFS mounts on the ESXi host
Explanation
The correct answer is B. Two RDMs on a FCP array, C. One NFS mount on the ESXi host and one RDMs on an iSCSI array, E. Two NFS mounts on the ESXi host. These options can be used because they provide different storage options that can be used for deduplication. Using two RDMs on a FCP array allows for deduplication to be performed on the storage array itself. Using one NFS mount on the ESXi host and one RDM on an iSCSI array allows for deduplication to be performed on both the ESXi host and the iSCSI array. Using two NFS mounts on the ESXi host allows for deduplication to be performed on both NFS mounts.
21.
An administrator has recently upgraded their Update Manager infrastructure to vSphere 5.x.
Several hosts and virtual machines have not been upgraded yet.
Which vSphere component when upgraded will have the least impact to the existing environment?
Correct Answer
D. D. VMware Tools
Explanation
Upgrading the VMware Tools will have the least impact on the existing environment because it is a software component that is installed inside the guest operating system of a virtual machine. It provides additional functionality and performance improvements, but upgrading it does not affect the underlying infrastructure or other virtual machines. On the other hand, upgrading the Virtual Machine Hardware, ESX Hosts, or VMFS datastores can have a more significant impact on the environment as it may require downtime, compatibility checks, and potential configuration changes.
22.
An administrator is using Update Manager 5.x to update virtual appliances in a vSphere
environment. The environment is using the vCenter Server Virtual Appliance (vCSA).
What would cause the remediation to fail?
Correct Answer
D. D. Remediation requires the hosts to be connected to vCenter using an IPv4 address.
23.
An administrator is working to update the hosts and virtual machines in a vSphere 5.x deployment
using Update Manager Baselines.
Other than host patches, which three items require a separate procedure or process to update?
(Choose three.)
Correct Answer(s)
A. A. Operating system patches
D. D. VMware Tools on machines without VMware Tools already installed
E. E. Application patches within the virtual machine
Explanation
The correct answer is A, D, and E. Operating system patches, VMware Tools on machines without VMware Tools already installed, and application patches within the virtual machine all require a separate procedure or process to update. These updates cannot be performed through the Update Manager Baselines and need to be handled separately.
24.
An administrator selects the Profile Compliance tab of an vSphere cluster, then selects Check
Compliance Now. Which features requirements are not checked by this?
Correct Answer
D. D. Host Profiles
Explanation
When the administrator selects the "Check Compliance Now" option on the Profile Compliance tab of a vSphere cluster, it checks the compliance of the cluster with the configured host profiles. Host profiles are used to ensure that hosts in the cluster are configured according to a predefined set of policies and settings. Therefore, the correct answer is D. Host Profiles, as this option specifically checks the compliance of host profiles and not the other features such as vMotion, Fault Tolerance, or DRS.
25.
An administrator is troubleshooting an ESXi 5.x host and needs to export diagnostic information.
The host is currently managed by a vCenter Server instance.
Which two ways can the information be gathered using the vSphere Client? (Choose two.)
Correct Answer(s)
A. A. Select Home. Under Administration, click System Logs and click the Export System Logs
button. Select the affected ESXi host. Select Select All. Select a location and click Finish.
D. D. In the vSpHere Client, select the affected ESXi host. Select File, Export and Export System
Logs. Select Select All. Select a location and click Finish.
Explanation
The correct answers for this question are A and D. Option A suggests that the administrator can navigate to the Home section in the vSphere Client, go to Administration, select System Logs, and click the Export System Logs button. They can then choose the affected ESXi host, select all the logs, specify a location, and click Finish to export the diagnostic information. Option D suggests that the administrator can select the affected ESXi host in the vSphere Client, go to the File menu, choose Export, and then select Export System Logs. They can then select all the logs, specify a location, and click Finish to export the diagnostic information.
26.
An ESXi 5.x host displays a warning icon in the vSphere console and its summary page lists a
configuration issue "SSH for the host has been enabled." What are two ways to clear this
warning? (Choose two.)
Correct Answer(s)
A. A. Using the Security Profile pane of the Configuration tab in the vSpHere Client
B. B. Using the Direct Console User Interface (DCUI)
Explanation
To clear the warning icon and configuration issue of "SSH for the host has been enabled" on an ESXi 5.x host, two ways can be used. The first way is to go to the vSphere Client, navigate to the Configuration tab, and select the Security Profile pane. From there, the SSH service can be disabled or configured as per the requirements. The second way is to use the Direct Console User Interface (DCUI) by accessing the host directly. In the DCUI, the SSH service can be disabled or configured.
27.
vCenter reports a connectivity problem with a ESXi 5.x host that is not a member of a cluster. An
administrator attempts to connect directly to the host using the vSphere Client but fails with the
message "An unknown connection error occurred." Virtual machines running on the host appear
to be running and report no problem.
What two methods would likely resolve the issue without affecting the virtual machines? (Choose
two.)
Correct Answer(s)
B. B. Select Restart Management Agents in the Direct Console User Interface (DCUI)
D. D. Enter the services.sh restart command from either SSH or the local CLI
Explanation
Restarting the management agents in the Direct Console User Interface (DCUI) or using the services.sh restart command from either SSH or the local CLI are both likely methods to resolve the connectivity problem with the ESXi host. These actions would restart the management services on the host without affecting the virtual machines running on it.
28.
ACME Catering Services is using esxtop to troubleshoot a performance problem with one of their
ESXi 5.x hosts. Host disconnections from vCenter Server as well as sluggish performance when
performing tasks on the host have been observed. Based on the output in the exhibit, how many
vCPU's have been assigned to FileServer01?
Correct Answer
D. D. 8
Explanation
Based on the output in the exhibit, we can see that the "PCPU USED(%)" column for the VM named "FileServer01" is consistently around 800%. This indicates that the VM is using 8 vCPUs, as each vCPU can utilize up to 100% of a physical CPU core. Therefore, the correct answer is D. 8.
29.
An administrator notices that log files kept on an ESXi 5.x host are being rotated very quickly,
inhibiting the troubleshooting of an issue. Which two configuration changes will resolve the issue?
(Choose two.)
Correct Answer(s)
A. A. Configure syslog to send the logs a syslog server
B. B. Increase the number of logs kept
Explanation
To resolve the issue of log files being rotated quickly, the administrator can make two configuration changes. First, they can configure syslog to send the logs to a syslog server. By doing this, the logs will be stored externally, allowing for easier troubleshooting without the logs being rotated. Second, they can increase the number of logs kept. This will ensure that a larger number of logs are available for troubleshooting purposes. Increasing the logging level or the size of the partition where log files are stored will not directly address the issue of log rotation.
30.
A series of Auto Deploy ESXi 5.x hosts which utilize vSphere Standard Switches are unable to
boot. In prior testing, all of the hosts were able to boot successfully.
Which two conditions might cause this issue? (Choose two.)
Correct Answer(s)
B. B. The TFTP server is down.
D. D. The DHCP server is down.
Explanation
The given correct answer states that the issue might be caused by the TFTP server being down and the DHCP server being down. This means that the hosts are unable to boot because they are unable to connect to the TFTP server to retrieve the necessary boot files, and they are also unable to obtain an IP address from the DHCP server. Both of these conditions can prevent the hosts from successfully booting.
31.
An administrator wants to monitor the health status of an ESXi 5.x host. However, when the administrator clicks the Hardware Status tab the following error is displayed.
This program cannot display the webpage
What might cause this problem?
Correct Answer
A. A. The VMware VirtualCenter Management Webservices Service is not started.
Explanation
The error message "This program cannot display the webpage" indicates that there is an issue with accessing the webpage. In this case, the problem is likely caused by the VMware VirtualCenter Management Webservices Service not being started. This service is responsible for providing the necessary web services for monitoring the health status of the ESXi host. Without this service running, the administrator will not be able to access the Hardware Status tab.
32.
An iSCSI array is being added to a vSphere 5.x implementation. An administrator wants to verify
that all IP storage VMkernel interfaces are configured for jumbo frames.
What are two methods to verify this configuration? (Choose two.)
Correct Answer(s)
A. A. Run the esxcli network ip interface list command
D. D. Ensure that the MTU size is set correctly in the VMkernel interface properties in the vSpHere
client
Explanation
To verify if all IP storage VMkernel interfaces are configured for jumbo frames in a vSphere 5.x implementation, the administrator can use two methods. First, they can run the "esxcli network ip interface list" command, which will display a list of network interfaces and their configurations. By checking the MTU (Maximum Transmission Unit) value for each interface, the administrator can determine if jumbo frames are enabled. Second, they can ensure that the MTU size is set correctly in the VMkernel interface properties in the vSphere client. By checking the MTU value in the interface properties, the administrator can confirm if jumbo frames are enabled.
33.
An administrator has configured a vSphere Distributed Switch to send all network traffic to a
collector virtual machine for analysis. However, after checking the collector virtual machine several
hours later the administrator finds that no data has been collected. vSphere 5.x has been
deployed in the datacenter.
Which two items below could be causing this issue? (Choose two.)
Correct Answer(s)
B. B. The source and target virtual machines are not both be on the same vSpHere Distributed
Switch.
D. D. The port group or distributed port does not have NetFlow enabled.
Explanation
The correct answer is B and D. The issue could be caused by the source and target virtual machines not being on the same vSphere Distributed Switch, as this is necessary for the traffic to be sent to the collector virtual machine. Additionally, the port group or distributed port may not have NetFlow enabled, which is required for the data to be collected and analyzed by the collector virtual machine.
34.
A vSphere 5 implementation consists of a fully automated DRS cluster with two ESXi 5.x hosts
with the following vSphere Standard Switch configuration.
1. Switch A. three vmnics, one port group named sFTP-PG
2. Switch B. two vmnic, one port group named Web-PG
3. All vmnics are trunked to the same physical switch.
DRS has been configured with an anti-affinity rule for all virtual machines in the Web-PG so that
no more than half of the virtual machines run on any given host. The virtual machines on WebPG
are experiencing significant network latency. The network team has determined that a
performance bottleneck is occurring at the ESXi host level.
Which solution will require the least amount of administrative work and the least amount of service
interruption?
Correct Answer
B. A. Migrate Web-PG to Switch A and sFTP-PG to Switch B on each host
Explanation
Migrating the Web-PG to Switch A and sFTP-PG to Switch B on each host would require the least amount of administrative work and service interruption. This solution involves simply reconfiguring the port groups on the existing switches, without the need to create new switches or redistribute virtual machines using vMotion. By separating the two port groups onto different switches, it can help alleviate the performance bottleneck at the ESXi host level and improve network latency for the virtual machines in the Web-PG.
35.
A user attempts a remote SSH connection to a newly-installed ESXi 5.x host to execute some
commands. The SSH connection attempt fails, though the user is able to receive a ICMP ping
back from the host. What must the administrator do to enable SSH? (Choose two.)
Correct Answer(s)
B. B. Open the SSH port on the ESXi firewall.
C. C. Start the SSH service on the ESXi server.
Explanation
To enable SSH on the newly-installed ESXi 5.x host, the administrator must open the SSH port on the ESXi firewall and start the SSH service on the ESXi server. Opening the SSH port on the firewall allows incoming SSH connections to reach the server, while starting the SSH service ensures that the server is actively listening for SSH connections. By doing these two steps, the user will be able to establish a remote SSH connection to the ESXi host and execute commands.
36.
An administrator is setting up vMotion in a vSphere environment. A migration is run to test the
configuration, but fails. What could the administrator do to resolve the issue?
Correct Answer
C. C. Ensure the vMotion enabled adaptors configured for the same subnet.
Explanation
The administrator should ensure that the vMotion enabled adaptors are configured for the same subnet. This is because vMotion requires the source and destination hosts to be on the same subnet in order to successfully migrate virtual machines. If the adaptors are not configured for the same subnet, the migration will fail.
37.
An administrator is unable to connect a vSphere Client to an ESXi 5.x host.
Which option can be selected from the direct console to restore connectivity without disrupting
running virtual machines?
Correct Answer
C. C. Restart the Management Agent from the ESXi host
Explanation
Restarting the Management Agent from the ESXi host can restore connectivity without disrupting running virtual machines. This option allows the administrator to restart the necessary services on the host without affecting the virtual machines.
38.
An administrator receives a complaint that a virtual machine is performing poorly. The user
attributes the issue to poor storage performance. If the storage array is the bottleneck, which two
counters would be higher than normal? (Choose two.)
Correct Answer(s)
B. B. Average ESXi highest latency, in milliseconds
C. C. Average virtual machine operating system latency per command, in milliseconds
Explanation
If the storage array is the bottleneck, the average ESXi highest latency would be higher than normal. This refers to the amount of time it takes for the ESXi host to process the storage commands. Additionally, the average virtual machine operating system latency per command would also be higher than normal. This indicates that the virtual machine is experiencing delays in accessing and processing data from the storage array.
39.
An administrator must decommission a datastore.
Before unmounting the datastore, which three requirements must be fullfilled? (Choose three.)
Correct Answer(s)
B. B. The datastore is not used for vSpHere HA heartbeat.
C. C. No registered virtual machines reside on the datastore.
E. E. The datastore must not be part of a datastore cluster.
Explanation
Before unmounting the datastore, the following three requirements must be fulfilled:
B. The datastore is not used for vSphere HA heartbeat: This ensures that the datastore is not being used for the high availability feature of vSphere.
C. No registered virtual machines reside on the datastore: This ensures that there are no virtual machines currently using the datastore.
E. The datastore must not be part of a datastore cluster: This ensures that the datastore is not part of a group of datastores that are managed together.
By fulfilling these requirements, the administrator can safely decommission the datastore without any potential issues or conflicts.
40.
An administrator is informed that there will be a storage maintenance window and that failovers
may occur.
What is the expected length of time that a Windows 2008 virtual machine storage I/O will pause
during a path failover?
Correct Answer
D. D. 30 to 60 seconds
Explanation
During a path failover in a Windows 2008 virtual machine, the expected length of time that the storage I/O will pause is between 30 to 60 seconds. This means that there may be a temporary interruption in the storage access for the virtual machine during the failover process.
41.
A company wants to increase disk capacity for their vSphere environment Management mandates
that:
1. vMotion must work in this environment.
2. The existing LAN infrastructure must be used.
Which storage option best meets the company objectives?
Correct Answer
D. D. NFS
Explanation
NFS (Network File System) is the best storage option that meets the company objectives. NFS allows for the sharing of files across a network and can be used with existing LAN infrastructure. It is also compatible with vMotion, which is a requirement for the company's vSphere environment. iSCSI and Fibre Channel are also viable options for increasing disk capacity, but they may require additional infrastructure and configuration. SATA is not a suitable option as it is a type of hard drive interface and not a storage option for network sharing.
42.
Which resource management technique can be used to relieve a network bottleneck caused by a
virtual machine with occasional high outbound network activity?
Correct Answer
B. B. Create a new portgroup for the virtual machine and enable traffic shaping.
Explanation
Creating a new portgroup for the virtual machine and enabling traffic shaping can help relieve a network bottleneck caused by occasional high outbound network activity. By creating a separate portgroup for the virtual machine, its network traffic can be isolated and managed separately from other virtual machines in the same port group. Enabling traffic shaping allows for the control and prioritization of network traffic, ensuring that the virtual machine with high activity does not overwhelm the network and cause a bottleneck.

An administrator has determined that storage performance to a group of virtual machines is
reduced during peak activity. The virtual machines are located in a VMFS datastore called
Production1 on an active-active storage array. The ESXi 5.x host running the virtual machines is
configured with an MRU multipathing policy.
Which two actions can be taken to improve the storage performance of these virtual machines?
(Choose two.)
Correct Answer(s)
B. B. Change the storage multipathing policy to Round Robin.
C. C. Add pHysical storage, create a VMFS datastore called Production2 on the new storage, and
then migrate some of the virtual machines from Production1 to Production2.
Explanation
To improve storage performance for the virtual machines located in the Production1 datastore, two actions can be taken. First, changing the storage multipathing policy to Round Robin will distribute I/O across all available paths, increasing throughput and reducing latency. Second, adding physical storage and creating a new VMFS datastore called Production2 will distribute the load across multiple datastores, further improving performance. Migrating some virtual machines from Production1 to Production2 will also help balance the workload and optimize performance.

Which of these factors indicates a high likelihood that the performance of a virtual machine disk is
being constrained by disk I/O?
Correct Answer
B. B. A high device latency value
Explanation
Disk performance bottlenecks are usually due to either Disk queue lenght or Disk Latency

An administrator is configuring vMotion in their environment. As part of the implementation, an
administrator is examining resource mapping for virtual machines.
What is a likely cause of the error shown in the exhibit?
Correct Answer
D. D. vMotion has not been enabled on a VMkernel port group.
Explanation
Explanation: This only shows up in the Maps when the vmotion OPTION is not checked in the
PORT group – hence vMotion is DISABLED!
Other Notes: vMotion doesn’t need a “production” network it can use any network. It also should
not be using a “production” network. Datastore has nothing to do with vMotion in this diagram –
this is Maps – it would give a vmotion error if it wasn’t on the datastore not a vmotion disabled..

Which two circumstances might cause a DRS cluster to become invalid? (Choose two.)
Correct Answer(s)
B. B. An ESXi host has been removed from the cluster.
D. D. Virtual machines have been powered on from a vSpHere Client connected directly to an ESXi
Explanation
If an ESXi host is removed from the cluster, it can cause the DRS cluster to become invalid as the cluster is no longer balanced and may not have enough resources to properly distribute the virtual machines. Additionally, if virtual machines are powered on directly from an ESXi host using the vSphere Client, it bypasses the DRS cluster and can cause the cluster to become invalid as the virtual machines are not being managed by DRS.

An administrator has a DRS/HA cluster with five ESXi 5.x hosts. When the administrator tries to
start a new Web server virtual machine, an error is displayed saying insufficient resources exist for
HA.
Based
Correct Answer(s)
A. A. Shut down one or more virtual machines on the cluster.
D. D. Suspend one or more virtual machines in the cluster.
Explanation
The correct answer is A. Shut down one or more virtual machines on the cluster and D. Suspend one or more virtual machines in the cluster. Both of these options involve freeing up resources by shutting down or suspending virtual machines on the cluster. By doing so, the administrator can allocate the necessary resources for starting the new Web server virtual machine and resolve the error of insufficient resources for HA.

An administrator is applying patches to a batch of ESXi 5.x hosts in an under-allocated HA/DRS
cluster. An attempt is made to place the host into maintenance mode, but the progress has stalled
at 2%. DRS is configured as shown in the exhibit. Of the four choices below, two would effectively
resolve this issue.
Which two steps could be taken to correct the problem? (Choose two.)
Correct Answer(s)
B. B. Set the virtual machines on the host to Fully Automated.
C. C. Shut down the virtual machines on the host.
Explanation
Setting the virtual machines on the host to Fully Automated would allow DRS to automatically migrate the virtual machines to other hosts in the cluster, freeing up resources on the host being placed in maintenance mode. Shutting down the virtual machines on the host would also free up resources and allow the host to enter maintenance mode successfully.
49.
An administrator is configuring Storage DRS in their environment. The Datastore cluster is
composed of 4 VMFS3 volumes and 9 VMFS5 volumes. Storage DRS has been enabled, but is
showing as disabled on several virtual machine disks in the datastore cluster.
Which two conditions would cause this error to occur? (Choose two.)
Correct Answer(s)
A. A. The virtual machine is stored on a VMFS 3 volume.
B. B. One or more virtual machines have Persistent disks.
Explanation
This error occurs because Storage DRS is not compatible with VMFS3 volumes, so if a virtual machine is stored on a VMFS3 volume, Storage DRS will be disabled for that virtual machine. Additionally, if one or more virtual machines have Persistent disks, Storage DRS will also be disabled for those virtual machines.

An administrator finds that vMotion and Storage vMotion operations do not succeed on a virtual
machine. The virtual machine has been configured with N_Port ID Virtualization. The virtual
machine has two data RDMs, one using a RAID5 LUN and one using a RAID0+1 LUN. The
mapping file for the RAID5 LUN was created on the same datastore as the virtual machine, and
the mapping file for the RAID0+1 LUN was placed in a datastore used for production data virtual
disks.
Which two statements are true about this configuration? (Choose two.)
Correct Answer(s)
B. B. vMotion cannot be used unless both mapping files are placed on the same datastore.
D. D. Storage vMotion cannot be used with NPIV.
Explanation
The correct answer is B. vMotion cannot be used unless both mapping files are placed on the same datastore. This is because vMotion requires both the virtual machine files and the mapping files to be located on the same datastore. Since the mapping file for the RAID0+1 LUN is placed in a different datastore, vMotion cannot be used for this virtual machine.
The answer D. Storage vMotion cannot be used with NPIV is incorrect because NPIV (N_Port ID Virtualization) does not impact the ability to use Storage vMotion. NPIV is a feature that allows multiple virtual machines to share a single physical Fibre Channel HBA port, and it does not affect the ability to perform Storage vMotion operations.
