Designing Cisco Enterprise Networks (ENSLD) — Question 26

Which consideration must be taken into account when using the DHCP relay feature in a Cisco SD-Access Architecture?

Answer options

• A. DHCP-relay must be enabled on fabric edge nodes to provide the correct mapping of DHCP scope to the local anycast gateway.
• B. A DHCP server must be enabled on the border nodes to allow subnets to span multiple fabric edges.
• C. DHCP servers must support Cisco SD-Access extensions to correctly assign IPs to endpoints in an SD-Access fabric with anycast gateway.
• D. DHCP Option-82 must be enabled to map the circuit IP option to the access fabric node where the DHCP discover originated.

Correct answer: D

Explanation

The correct answer is D because enabling DHCP Option-82 is crucial for identifying the specific access fabric node that initiated the DHCP discover process. Options A and B are incorrect because they pertain to different configurations that do not directly affect the DHCP relay feature, and Option C is wrong as it refers to server support rather than relay functionality.
