HPE Aruba Certified Network Security Expert (ACNSX) — Question 13

What is correct regarding the operation of VSX and multicasting with PIM-SM routing configured?

Answer options

• A. Each VSX peers runs PIM and builds its own group database. One of the VSX peers is elected as the designated router (DR) to forward multicast streams to a receiver VLAN
• B. Each VSX peers runs PIM and creates a shared group database. Both VSX peers can forward multicast streams to receivers in a VLAN, achieving load sharing
• C. Each VSX peers runs PIM and builds its own group database. Both VSX peers can forward multicast streams to receivers in a VLAN, achieving load sharing
• D. Each VSX peers runs PIM and creates a shared group database. One of the VSX peers is elected as the designated router (DR) to forward multicast streams to a receiver VLAN

Correct answer: A

Explanation

The correct answer is A because each VSX peer operates independently with its own group database, and only one can be the designated router (DR) for forwarding multicast streams. Options B and D incorrectly state that a shared group database is used, while option C suggests that both peers can forward streams, which contradicts the designated router concept in this configuration.
