NEW QUESTION # 15
Multichassis Link Aggregation Group (M-LAG) bundles multiple physical links connecting ServerA (a device or host) to DeviceA and DeviceB into a logical link, and allows DeviceA and DeviceB to appear to ServerA as a single device, improving link reliability from card-level to device-level.
- A. TRUE
- B. FALSE
Answer: A
Explanation:
In Huawei data center networking, M-LAG (Multi-Chassis Link Aggregation Group) is a critical technology used to provide active-active access, high availability, and link redundancy . It allows a downstream device (such as a server) to establish a single logical Eth-Trunk across two separate physical switches (DeviceA and DeviceB).
From the server's perspective, both upstream switches appear as one logical device , which eliminates the need for protocols like STP and enables simultaneous forwarding on all active links . This significantly improves bandwidth utilization and avoids blocked links.
The key advantage highlighted in the statement is the improvement of reliability from card-level to device- level . In traditional single-device link aggregation, failures are limited to interface cards. However, with M- LAG, even if an entire switch (device-level failure) goes down, traffic continues to flow through the other active switch without interruption.
Huawei CloudFabric widely adopts M-LAG + VXLAN EVPN to ensure high reliability, fast convergence, and continuous service availability .
Therefore, the statement is TRUE .
