Alcatel-Lucent NRS I – Layer 2 Switching and Spanning Tree — Question 4

What is the function of the Cluster_List attribute?

Answer options

• A. It is used for loop detection within the same cluster.
• B. It is used for loop detection between clusters.
• C. It is used for loop detection in a confederation.
• D. It is used to identify the route reflectors within an AS.

Correct answer: B

Explanation

The correct answer is B because the Cluster_List attribute is specifically designed to detect loops between different clusters in BGP. Option A is incorrect as it refers to loop detection within a single cluster, while C pertains to confederations, and D focuses on route reflectors, which are unrelated to the Cluster_List function.
