Implementing Cisco ACI Advanced (DCACIA) — Question 25

What is a use of the Overlay Multicast TEP in Cisco ACI Multi-Site communication?

Answer options

• A. to perform headend replication
• B. to act as the source IP for BUM traffic
• C. to establish MP-BGP adjacencies with remote spines
• D. to send and receive unicast VXLAN data plane traffic

Correct answer: B

Explanation

The correct answer is B because the Overlay Multicast TEP is responsible for acting as the source IP for Broadcast, Unknown Unicast, and Multicast (BUM) traffic within ACI Multi-Site setups. Option A is incorrect as headend replication is not the primary function of the TEP, C is wrong since MP-BGP adjacencies are established by different components, and D is incorrect because the TEP does not handle unicast VXLAN traffic.
