Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) — Question 222

In an EVPN operation how does the PE determine and advertise Ethernet segment reachability?

Answer options

• A. The PE discovers and shares routing information for the B-MAC addresses associated with local Ethernet segments.
• B. The PE discovers remote ESIs and determines their redundancy mode.
• C. The PE discovers the remote PEs in the EVI and builds a flood list linked with the EVI.
• D. The PE discovers other PEs in the same Ethernet segment and elects a DF.

Correct answer: C

Explanation

The correct answer is C because the PE needs to discover remote PEs in the same Ethernet Virtual Instance (EVI) to create a flood list for efficient communication. Options A and B focus on local and redundancy aspects, while D pertains to DF election, which is not directly related to advertising Ethernet segment reachability.
