Refer to the exhibit. Assuming that the routing tables are up to date and no ARP messages are needed, after a packet leaves H1, how many times is the L2 header rewritten in the path to H3?
- A.
1
- B.
2
- C.
3
- D.
4
- E.
5
- F.
6
Correct Answer
B. 2Explanation
After a packet leaves H1, it will first go through the switch, where the Layer 2 (L2) header will be rewritten to include the MAC address of the switch. Then, the packet will be forwarded to the router, where the L2 header will be rewritten again to include the MAC address of the router. Finally, the packet will be forwarded to H3 without any further L2 header rewrites. Therefore, the L2 header is rewritten twice in the path to H3.Rate this question:

On which two routers would a default static route be configured? (Choose two.)
- A.
Stub router connection to the rest of the corporate or campus network
- B.
Any router where a backup route to dynamic routing is needed for reliability
- C.
Edge router connection to the ISP
- D.
Any router running an IOS prior to 12.0
- E.
The router that serves as the gateway of last resort
Correct Answer(s)
A. Stub router connection to the rest of the corporate or campus network
C. Edge router connection to the ISPExplanation
A default static route is typically configured on a stub router connection to the rest of the corporate or campus network and on an edge router connection to the ISP.
The stub router is responsible for connecting a smaller network (such as a branch office or a department) to the larger corporate or campus network. By configuring a default static route on this router, any traffic that is not destined for the local network will be forwarded to the corporate or campus network.
The edge router, on the other hand, is responsible for connecting the internal network to the external network (ISP). By configuring a default static route on this router, any traffic that is not destined for the internal network will be forwarded to the ISP.
Therefore, a default static route would be configured on both the stub router connection to the rest of the corporate or campus network and the edge router connection to the ISP.Rate this question:

R2(config)# ip route 172.16.2.1 255.255.255.0 172.16.3.1
- B.
R2(config)# ip route 172.16.2.0 255.255.255.0 172.16.2.254
- C.
R2(config)# ip route 172.16.2.0 255.255.255.0 172.16.3.1
- D.
R2(config)# ip route 172.16.3.0 255.255.255.0 172.16.2.254
Correct Answer
C. R2(config)# ip route 172.16.2.0 255.255.255.0 172.16.3.1Explanation
This command will create a static route on R2 to reach PC B. It specifies the destination network as 172.16.2.0 with a subnet mask of 255.255.255.0. The next hop address is set to 172.16.3.1, indicating that packets destined for PC B should be forwarded to this IP address.Rate this question:

Refer to the exhibit. R1 was configured with the static route command ip route 209.165.200.224 255.255.255.224 S0/0/0 and consequently users on network 172.16.0.0/16 are unable to reach resources on the Internet. How should this static route be changed to allow user traffic from the LAN to reach the Internet?
- A.
Add the next-hop neighbor address of 209.165.200.226.
- B.
Change the exit interface to S0/0/1.
- C.
Change the destination network and mask to 0.0.0.0 0.0.0.0.
- D.
Add an administrative distance of 254.
Correct Answer
C. Change the destination network and mask to 0.0.0.0 0.0.0.0.Explanation
The correct answer is to change the destination network and mask to 0.0.0.0 0.0.0.0. This is because the static route command with the given destination network and mask of 209.165.200.224 255.255.255.224 is too specific and only allows traffic to reach a specific subnet. By changing the destination network and mask to 0.0.0.0 0.0.0.0, it becomes a default route that matches any destination IP address, allowing user traffic from the LAN to reach the Internet.Rate this question:

A router has used the OSPF protocol to learn a route to the 172.16.32.0/19 network. Which command will implement a backup floating static route to this network?
- A.
Ip route 172.16.0.0 255.255.240.0 S0/0/0 200
- B.
Ip route 172.16.32.0 255.255.224.0 S0/0/0 200
- C.
Ip route 172.16.0.0 255.255.224.0 S0/0/0 100
- D.
Ip route 172.16.32.0 255.255.0.0 S0/0/0 100
Correct Answer
B. Ip route 172.16.32.0 255.255.224.0 S0/0/0 200Explanation
This command will implement a backup floating static route to the 172.16.32.0/19 network because it specifies the correct network address and subnet mask (172.16.32.0 255.255.224.0). The next-hop interface is S0/0/0 and the administrative distance is set to 200, indicating that it is a backup route.Rate this question:

Refer to the exhibit. Router R1 has an OSPF neighbor relationship with the ISP router over the 192.168.0.32 network. The 192.168.0.36 network link should serve as a backup when the OSPF link goes down. The floating static route command ip route 0.0.0.0 0.0.0.0 S0/0/1 100 was issued on R1 and now traffic is using the backup link even when the OSPF link is up and functioning. Which change should be made to the static route command so that traffic will only use the OSPF link when it is up?
- A.
Add the next hop neighbor address of 192.168.0.36.
- B.
Change the administrative distance to 1.
- C.
Change the destination network to 192.168.0.34.
- D.
Change the administrative distance to 120.
Correct Answer
D. Change the administrative distance to 120.Explanation
The administrative distance determines the preference of routes when there are multiple paths to the same destination. A lower administrative distance indicates a more preferred route. In this case, the static route has an administrative distance of 100, which is lower than the OSPF route. Therefore, traffic is being sent through the backup link instead of the OSPF link. By changing the administrative distance to 120, which is higher than the OSPF route's administrative distance, the static route will only be used when the OSPF link is down.Rate this question:

Which statement describes a route that has been learned dynamically?
- A.
It is automatically updated and maintained by routing protocols.
- B.
It is unaffected by changes in the topology of the network.
- C.
It has an administrative distance of 1.
- D.
It is identified by the prefix C in the routing table.
Correct Answer
A. It is automatically updated and maintained by routing protocols.Explanation
A dynamically learned route is automatically updated and maintained by routing protocols. Routing protocols are responsible for exchanging information about network topology and updating routing tables accordingly. This ensures that the route remains up-to-date and reflects any changes in the network. The other statements are not necessarily true for dynamically learned routes. They may be affected by changes in the network topology, have different administrative distances, and may be identified by different prefixes in the routing table.Rate this question:

Compared with dynamic routes, what are two advantages of using static routes on a router? (Choose two.)
- A.
They improve network security.
- B.
They use fewer router resources.
- C.
They improve the efficiency of discovering neighboring networks.
- D.
They take less time to converge when the network topology changes.
- E.
They automatically switch the path to the destination network when the topology changes.
Correct Answer(s)
A. They improve network security.
B. They use fewer router resources.Explanation
Static routes improve network security because they do not advertise network information, making it harder for potential attackers to gain knowledge about the network. Additionally, static routes use fewer router resources compared to dynamic routes, as they do not require the router to continuously update and maintain routing tables.Rate this question:

What will a Cisco LAN switch do if it receives an incoming frame and the destination MAC address is not listed in the MAC address table?
- A.
Drop the frame.
- B.
Send the frame to the default gateway address.
- C.
Use ARP to resolve the port that is related to the frame.
- D.
Forward the frame out all ports except the port where the frame is received.
Correct Answer
D. Forward the frame out all ports except the port where the frame is received.Explanation
If a Cisco LAN switch receives an incoming frame and the destination MAC address is not listed in the MAC address table, it will forward the frame out all ports except the port where the frame is received. This is because the switch does not have the information about the destination MAC address in its table, so it assumes that the frame needs to be broadcasted to all connected devices in order to reach the intended destination.Rate this question:

Which advantage does the store-and-forward switching method have compared with the cut-through switching method?
- A.
Collision detecting
- B.
Frame error checking
- C.
Faster frame forwarding
- D.
Frame forwarding using IPv4 Layer 3 and 4 information
Correct Answer
B. Frame error checkingExplanation
The store-and-forward switching method has an advantage over the cut-through switching method because it performs frame error checking. This means that before forwarding a frame, it checks for any errors in the frame's data. This ensures that only error-free frames are forwarded, leading to better data integrity and reliability in the network. In contrast, the cut-through switching method does not perform frame error checking and forwards frames without verifying their integrity.Rate this question:
-
- 18.
Which switching method drops frames that fail the FCS check?
- A.
Borderless switching
- B.
Cut-through switching
- C.
Ingress port buffering
- D.
Store-and-forward switching
Correct Answer
D. Store-and-forward switchingExplanation
Store-and-forward switching is a method in which the switch receives the entire frame before forwarding it to the destination. It checks the Frame Check Sequence (FCS) to ensure the integrity of the frame. If the FCS check fails, indicating an error in the frame, the switch drops the frame. Therefore, store-and-forward switching is the switching method that drops frames that fail the FCS check.Rate this question:

In what situation would a Layer 2 switch have an IP address configured?
- A.
When the Layer 2 switch needs to forward user traffic to another device
- B.
When the Layer 2 switch is the default gateway of user traffic
- C.
When the Layer 2 switch needs to be remotely managed
- D.
When the Layer 2 switch is using a routed port
Correct Answer
C. When the Layer 2 switch needs to be remotely managedExplanation
A Layer 2 switch would have an IP address configured when it needs to be remotely managed. This allows administrators to access and configure the switch remotely over a network. By assigning an IP address to the switch, it can be accessed using protocols such as Telnet, SSH, or web-based management interfaces. This is particularly useful in larger networks where physical access to the switch may not be convenient or feasible.Rate this question:

- C.
Vty lines
- D.
Default VLAN
- E.
Default gateway
- F.
Loopback address
Correct Answer(s)
A. IP address
C. Vty lines
E. Default gatewayExplanation
To enable remote management access on a Cisco switch, the following three items need to be configured:
1. IP address: This is necessary to assign an IP address to the switch so that it can be accessed remotely over the network.
2. vty lines: These are virtual terminal lines that allow remote users to connect to the switch using protocols like Telnet or SSH.
3. Default gateway: This is the IP address of the router or gateway that the switch will use to forward traffic to other networks or the internet.
These three configurations are essential for enabling remote management access on a Cisco switch.Rate this question:

As part of the new security policy, all switches on the network are configured to automatically learn MAC addresses for each port. All running configurations are saved at the start and close of every business day. A severe thunderstorm causes an extended power outage several hours after the close of business. When the switches are brought back online, the dynamically learned MAC addresses are retained. Which port security configuration enabled this?
- A.
Auto secure MAC addresses
- B.
Dynamic secure MAC addresses
- C.
Static secure MAC addresses
- D.
Sticky secure MAC addresses
Correct Answer
D. Sticky secure MAC addressesExplanation
The correct answer is "sticky secure MAC addresses". Sticky secure MAC addresses is a port security configuration that allows the switch to dynamically learn and retain MAC addresses for each port. This means that even after a power outage, the learned MAC addresses are still retained when the switches are brought back online. The other options, such as auto secure MAC addresses, dynamic secure MAC addresses, and static secure MAC addresses, do not specifically mention the retention of dynamically learned MAC addresses after a power outage.Rate this question:

A network administrator is configuring port security on a Cisco switch. When a violation occurs, which violation mode that is configured on an interface will cause packets with an unknown source address to be dropped with no notification sent?
- A.
Off
- B.
Restrict
- C.
Protect
- D.
Shutdown
Correct Answer
C. ProtectExplanation
When the violation mode "protect" is configured on an interface, it will cause packets with an unknown source address to be dropped without sending any notification. This means that if a device with an unauthorized or unknown MAC address tries to send packets through the interface, those packets will be dropped without any alert being sent to the network administrator.Rate this question:

- A.
Another switch was connected to this switch port with the wrong cable.
- B.
An unauthorized user tried to telnet to the switch through switch port Fa0/8.
- C.
NAT was enabled on a router, and a private IP address arrived on switch port Fa0/8.
- D.
A host with an invalid IP address was connected to a switch port that was previously unused.
- E.
Port security was enabled on the switch port, and an unauthorized connection was made on switch port Fa0/8.
Correct Answer
E. Port security was enabled on the switch port, and an unauthorized connection was made on switch port Fa0/8.Explanation
The error message indicates that a security violation occurred on switch port Fa0/8, resulting in the port being put into an err-disable state. This suggests that port security was enabled on the switch port, and an unauthorized connection was made. Port security is a feature that allows administrators to restrict access to a switch port based on MAC addresses. In this case, the MAC address 0011.a0d4.12a0 was detected on the port, indicating that an unauthorized device attempted to connect. As a result, the port was disabled to prevent any further unauthorized access.Rate this question:

Which statement describes a characteristic of the extended range VLANs that are created on a Cisco 2960 switch?
- A.
They are numbered VLANs 1002 to 1005.
- B.
They cannot be used across multiple switches.
- C.
They are reserved to support Token Ring VLANs.
- D.
They are not stored in the vlan.dat file.
Correct Answer
D. They are not stored in the vlan.dat file.Explanation
Extended range VLANs are not stored in the vlan.dat file. The vlan.dat file is used to store the VLAN configuration information on a Cisco switch. However, extended range VLANs, which are VLANs numbered from 1006 to 4094, are not stored in this file. Instead, they are stored in a separate file called the vlan.dat-1 file. This allows for better management and organization of the VLAN configuration on the switch.Rate this question:
