Designing Cisco Data Center Infrastructure (DCID) — Question 48

An engineer must design a VXLAN EVPN network. The solution should optimize broadcast, unknown unicast, and multicast (BUM) and short BUM replication, and use PIM anycast RP.

Which solution should be included in the design?

Answer options

• A. head-end replication
• B. PIM sparse mode
• C. PIM dense mode
• D. ingress replication

Correct answer: B

Explanation

The correct answer is B, PIM sparse mode, as it efficiently handles multicast traffic in large networks by reducing unnecessary data transmission. The other options either do not optimize multicast traffic effectively or are not suitable for the requirements of the VXLAN EVPN network.
