JNCIE-DC: Juniper Networks Certified Expert – Data Center — Question 9

Your network design consists of two chassis clusters with the same cluster ID. The reth0 interfaces of each cluster are connected to the same Layer 2 network.
In this scenario, what will ensure uninterrupted traffic?

Answer options

• A. One of the clusters should not use reth0.
• B. One of the clusters should have a different number of physical interfaces in reth0.
• C. One of the clusters should disable LACP on all redundant interfaces.
• D. One of the clusters should have reth0 configured under different redundancy groups.

Correct answer: D

Explanation

The correct answer is D because configuring reth0 under different redundancy groups allows each cluster to manage its traffic independently, preventing conflicts. Options A, B, and C do not address the issue of traffic interruption effectively, as they either remove necessary interfaces or misconfigure existing ones, which could lead to network issues.
