Designing Cisco Enterprise Networks (ENSLD) — Question 5

Which design element should an engineer consider when multicast is included in a Cisco SD-Access architecture?

Answer options

• A. PIM SSM must run in the underlay.
• B. Multicast clients reside in the underlay, and the multicast source is outside the fabric or in the overlay.
• C. Rendezvous points must be used in a PIM SSM deployment.
• D. Multicast traffic is transported in the overlay and the EID space for wired and wireless clients.

Correct answer: D

Explanation

The correct answer is D because in a Cisco SD-Access architecture, multicast traffic is indeed encapsulated in the overlay, allowing for efficient delivery to both wired and wireless endpoints. Options A and C are incorrect as they pertain to PIM SSM configurations that are not a requirement in this context, while option B misplaces the location of multicast clients and the source.
