Exam H12-893_V1.0 Topic 2 Question 4 Discussion

In Huawei's M-LAG (Multi-Chassis Link Aggregation) on CE series switches, the two member devices synchronize critical information over the peer-link to ensure seamless operation and failover. Let's evaluate each option:
A . ACL information: Access Control List (ACL) configurations are typically not synchronized in M-LAG, as they are device-specific security policies. Synchronization of ACLs is not a standard feature in Huawei's M-LAG implementation. NOT SYNCHRONIZED.
B . STP status: Spanning Tree Protocol (STP) status (e.g., port roles, states) is synchronized to maintain a consistent loop-free topology across M-LAG peers, especially when V-STP or other STP variants are used. SYNCHRONIZED.
C . Device name: Device names are administrative identifiers and are not synchronized, as they do not impact traffic forwarding or M-LAG functionality. NOT SYNCHRONIZED.
D . LACP information: Link Aggregation Control Protocol (LACP) status (e.g., link states, aggregation details) is synchronized to ensure both M-LAG devices present a unified LAG to downstream devices, supporting load balancing and failover. SYNCHRONIZED.
Thus, B (STP status) and D (LACP information) are synchronized between M-LAG devices.
