JNCIP-DC: Juniper Networks Certified Professional – Data Center (2022) — Question 9

Which EVPN route type prevents BUM traffic from looping back to a multihomed host?

Answer options

• A. IP prefix route
• B. Ethernet autodiscovery route
• C. Ethernet segment route
• D. inclusive multicast-Ethernet tag route

Correct answer: B

Explanation

The Ethernet autodiscovery route is designed to prevent BUM traffic from looping back to multihomed hosts by providing a mechanism for identifying and managing the paths taken by this traffic. The other options, such as IP prefix route and Ethernet segment route, do not have this specific functionality, while the inclusive multicast-Ethernet tag route focuses on multicast traffic handling without the same loop prevention characteristics.
