JNCIS-DCD: Juniper Networks Certified Specialist – Data Center Deployment — Question 42

You have two sites connected to an EVPN network. Each site is using the 172.16.1.0/24 network for its own respective site.
How does EVPN prevent overlap in this scenario?

Answer options

• A. It elects a designated forwarder.
• B. It uses a Layer 2 gateway.
• C. It uses a route distinguisher.
• D. It uses an Ethernet segment identifier (ESI).

Correct answer: C

Explanation

The correct answer is C, as a route distinguisher is essential in EVPN to ensure that overlapping IP addresses from different sites can be uniquely identified. Options A and B are not relevant to preventing address overlap, while option D, although related to EVPN, does not specifically address the issue of overlapping address spaces.
