DHCP (dynamic host configuration protocol) provides __________ to the client.
Correct Answer
A. IP address
Explanation
DHCP (Dynamic Host Configuration Protocol) provides IP addresses to the client. It is a network protocol that allows devices to obtain IP addresses automatically from a DHCP server. This eliminates the need for manual configuration of IP addresses, making it easier to manage and allocate IP addresses in a network. DHCP ensures that each device on the network has a unique IP address, enabling communication and connectivity between devices.
2.
DHCP is used for ________
Correct Answer
C. BOTH IPV4 AND IPV6
Explanation
DHCP (Dynamic Host Configuration Protocol) is a network management protocol used to automatically assign IP addresses and other network configuration settings to devices on a network. It is used for both IPv4 and IPv6 networks. DHCP ensures that devices can connect to the network and communicate with other devices by providing them with unique IP addresses and necessary network information. Therefore, the correct answer is "BOTH IPV4 AND IPV6".
3.
The DHCP server _________
Correct Answer
D. All of the mentioned
Explanation
The DHCP server performs multiple functions. It maintains a database of available IP addresses, which allows it to allocate and assign IP addresses to clients when they request one. Additionally, the DHCP server also maintains information about client configuration parameters, such as subnet mask, default gateway, and DNS servers. Therefore, it can be concluded that the DHCP server performs all of the mentioned functions.
4.
IP assigned for a client by DHCP server is
Correct Answer
A. For a limited period
Explanation
The IP address assigned to a client by a DHCP server is for a limited period of time. DHCP (Dynamic Host Configuration Protocol) is a network protocol that automatically assigns IP addresses to devices on a network. The IP address lease provided by the DHCP server is temporary and has a specific duration. After the lease period expires, the client may need to renew the lease or request a new IP address. Therefore, the IP assigned by the DHCP server is not permanent and is valid for a limited period.
5.
DHCP uses UDP port _________ for sending data to the server.
Correct Answer
B. 67
Explanation
DHCP uses UDP port 67 for sending data to the server. The Dynamic Host Configuration Protocol (DHCP) is a network management protocol used to automatically assign IP addresses and other network configuration parameters to devices on a network. UDP (User Datagram Protocol) is a connectionless protocol that operates at the transport layer of the OSI model. It is used for sending data packets between devices on a network. In the case of DHCP, the server listens for DHCP requests on port 67, and the client sends its requests to the server using this port.
6.
The DHCP server can provide the _______ of the IP addresses.
Correct Answer
D. all of the mentioned
Explanation
The DHCP server can provide all of the mentioned types of IP address allocation. It can dynamically allocate IP addresses, automatically allocate IP addresses, or use static allocation depending on the configuration and requirements of the network.
7.
DHCP client and servers on the same subnet communicate via _________
Correct Answer
A. UDP broadcast
Explanation
DHCP clients and servers on the same subnet communicate via UDP broadcast. UDP (User Datagram Protocol) is a connectionless protocol that allows for broadcasting messages to multiple devices on a network. In the case of DHCP, the client sends a broadcast message requesting an IP address, and the server responds with a broadcast message containing the assigned IP address. This allows for efficient communication between clients and servers on the same subnet without the need for establishing individual connections.
8.
After obtaining the IP address, to prevent the IP conflict the client may use _________
Correct Answer
C. Address resolution protocol
Explanation
To prevent IP conflict, the client may use the Address Resolution Protocol (ARP). ARP is a protocol used to map an IP address to a physical (MAC) address on a local network. It allows devices to communicate with each other by resolving the IP address of a device to its corresponding MAC address. By using ARP, the client can ensure that there are no conflicts in IP addresses within the network, as each device will have a unique MAC address associated with its IP address.
9.
What is DHCP snooping?
Correct Answer
A. Techniques applied to ensure the security of an existing DHCP infrastructure
Explanation
DHCP snooping refers to techniques applied to ensure the security of an existing DHCP infrastructure. It is a security feature that helps prevent unauthorized DHCP servers from providing IP addresses to network clients. By snooping on DHCP messages and verifying the legitimacy of DHCP servers, it provides a layer of protection against rogue DHCP servers and potential network attacks. This helps maintain the integrity and security of the DHCP infrastructure within a network.
10.
If DHCP snooping is configured on a LAN switch, then clients having specific ______ can access the network.
Correct Answer
C. Both MAC address and IP address
Explanation
If DHCP snooping is configured on a LAN switch, clients with specific MAC addresses and IP addresses can access the network. DHCP snooping is a security feature that prevents unauthorized devices from obtaining IP addresses from the DHCP server. By snooping on DHCP messages, the switch can verify the legitimacy of the MAC and IP addresses being used by clients. Therefore, both the MAC address and IP address are required for clients to access the network when DHCP snooping is enabled.

Your company has a main office. The main office is located in a building that has 10 floors.
A datacenter on the ground floor contains a Windows Server 2012 failover cluster. The failover cluster contains a DHCP server resource named DHCP1. All client computers receive their IP addresses from DHCP1. All client computers are part of the 131.107.0.0/16 IPv4 subnet.
You plan to implement changes to the network subnets to include a separate subnet for each floor of the office building. The subnets will connect by using routers.
You need to recommend changes to the DHCP infrastructure to ensure that all of the client computers can receive their IP configuration by using DHCP.
What should you recommend?
Correct Answer
C. Configure each router to forward requests for IP addresses to DHCP1. Create a scope for each subnet on DHCP1.
Explanation
To ensure that all client computers on each floor can receive their IP configuration by using DHCP, it is recommended to configure each router to forward requests for IP addresses to DHCP1 and create a scope for each subnet on DHCP1. By forwarding the requests to DHCP1, the DHCP server can assign IP addresses to the client computers on each floor. Creating a scope for each subnet on DHCP1 ensures that the IP addresses assigned are within the appropriate subnet range for each floor. This setup allows for centralized management of DHCP and ensures that all client computers can receive their IP configuration correctly.
