A systems engineer is configuring a new VLAN for expansion of a campus network. The engineer configures a new DHCP scope on the existing Windows DHCP server cluster and activates the scope for the clients. However, new clients in the area report they are not receiving any DHCP address information. Which of the following should the engineer do first?

A.

Confirm the client PCs are using the correct speed on the NIC

Answers
A.

Confirm the client PCs are using the correct speed on the NIC

B.

Confirm the network uses the same NTP server as the clients

Answers
B.

Confirm the network uses the same NTP server as the clients

C.

Confirm the network has a helper address for the DHCP server

Answers
C.

Confirm the network has a helper address for the DHCP server

D.

Confirm the DHCP server is authorized in Active Directory

Answers
D.

Confirm the DHCP server is authorized in Active Directory

Suggested answer: C

Explanation:

When clients on a different VLAN cannot receive DHCP addresses, it's often because there is no DHCP helper address configured on the router or switch. A DHCP relay/helper address forwards DHCP requests from clients on the VLAN to the DHCP server, which may reside on a different network.

Confirming the network has a helper address (Answer C): This should be the first step to ensure that DHCP requests from the VLAN are correctly routed to the DHCP server.

Checking client NIC speed (Option A): While important, incorrect NIC speed wouldn't affect the ability to obtain an IP address from DHCP.

Checking NTP server (Option B): Time synchronization is unrelated to DHCP issues.

Authorizing the DHCP server (Option D): This is essential for DHCP operation, but since this is an existing DHCP cluster, the helper address is more likely the issue.
