CCNA: Cisco Certified Network Associate — Question 604

What are two features of the DHCP relay agent? (Choose two.)

Answer options

• A. assigns DNS locally and then forwards request to DHCP server
• B. minimizes the necessary number of DHCP servers
• C. permits one IP helper command under an individual Layer 3 interface
• D. is configured under the Layer 3 interface of a router on the client subnet
• E. allows only MAC-to-IP reservations to determine the local subnet of a client

Correct answer: B, D

Explanation

Option B is correct because a DHCP relay agent helps reduce the number of DHCP servers needed by allowing a single server to serve multiple subnets. Option D is also correct since the relay agent must be configured on the Layer 3 interface of a router that is part of the client's subnet. The other options either describe incorrect functionalities or are not specific to DHCP relay agents.
