DHCP Relay and Network Management Quiz

A company has offices in different cities, and each office has its own local subnet but no dedicated DHCP server. The IT team has configured routers with DHCP Relay to handle IP address requests from different offices. If the router’s DHCP Relay configuration is incorrect, which of the following is the most likely result?

• The router would send IP address requests to all available DHCP servers in the network.

• Devices on the local subnet would receive incorrect IP configurations from an unrelated DHCP server.

• Devices on the subnet would be unable to communicate with any other devices on the network.

• Devices on the local subnet would fail to receive IP addresses from the DHCP server, preventing network connectivity.

Consider a large network with multiple DHCP servers and relays to manage high traffic and redundancy. After a new DHCP server is added, you notice network devices randomly failing to receive IP addresses. Which of the following changes would be most effective in diagnosing and correcting the issue?

• Disconnecting one DHCP server at a time and observing which devices continue to have IP conflicts.

• Changing DHCP server priorities in the relay settings and logging which server responds first.

• Configuring each DHCP relay to prioritize specific DHCP servers for designated subnets.

• Switching the network to manual IP configuration to ensure no IP address conflicts arise.

A network is experiencing delays in IP address allocation despite having a functioning DHCP Relay. Network analysis shows that the router handling the DHCP Relay is often overloaded. Which of the following solutions would best address this issue?

• Disabling the DHCP Relay function and setting up a local DHCP server on each subnet.

• Configuring a backup DHCP Relay on a secondary router and enabling load balancing between the relays.

• Increasing the timeout period on the DHCP server to reduce the frequency of IP lease renewals.

• Setting a static IP address for devices that require constant connectivity, thus reducing DHCP requests.

In a network with multiple routers and one DHCP server located in a secure data center, you’re tasked with optimizing DHCP efficiency and ensuring availability during peak hours. Which of the following strategies would most effectively accomplish this?

• Configure each router with an identical DHCP Relay IP Helper configuration pointing to the data center DHCP server.

• Segmenting the network by subnet and dedicating a specific DHCP server to each segment.

• Configuring dynamic DNS updates to accompany IP assignments for easier troubleshooting.

• Establishing a DHCP load-balancing protocol where IP ranges are partitioned and managed by different servers.

An enterprise network utilizes DHCP Relays across its routers to manage IP address assignments from a centralized DHCP server. Which of the following scenarios would require the most advanced troubleshooting to resolve a failure in IP address assignment?

• The DHCP Relay configuration on the router is set to an incorrect IP address.

• A newly connected device receives an IP address already assigned to another device.

• The DHCP server’s offer messages are not reaching devices on a remote subnet due to incorrect routing.

• A network switch fails, affecting connectivity to the DHCP Relay but not to other devices on the subnet.

The DHCP Discover message is initially sent as a broadcast because the requesting device does not yet have an IP address.

• True

• False

DHCP Relay allows DHCP messages to traverse routers by relaying the request from one subnet to a DHCP server on a different subnet.

• True

• False

BOOTP automatically reassigns IP addresses when they become available, making it superior to DHCP in dynamic environments.

• True

• False

A DHCP server assigns IP addresses directly to devices on any subnet without needing assistance from other network components.

• True

• False

The DHCP Request message is sent to confirm that the client wants to use the offered IP address before it is fully assigned.

• True

• False
