Question
Which of the following statements about AC VRRP HSB are true? (Choose all that apply.)
A. The active/standby mode is supported.
B. Load balancing mode is supported.
C. User data is backed up in real time.
D. Configuration synchronization is supported.
Answer
A. The active/standby mode is supported.
C. User data is backed up in real time.
D. Configuration synchronization is supported.
Explanation
The correct answers are A, C, and D. The following statements about Huawei’s AC VRRP HSB (Virtual Router Redundancy Protocol Hot Standby) are true:
A. The active/standby mode is supported. In this mode, one AC acts as the active device handling all operations while the other AC serves as a standby, ready to take over if the active AC fails. This provides redundancy and high availability.
C. User data is backed up in real time. Any configuration changes made on the active AC are automatically synchronized to the standby AC. This ensures the standby has an up-to-date copy of user data and configuration.
D. Configuration synchronization is supported between the active and standby ACs. This keeps the ACs in sync and allows the standby to seamlessly take over if needed without disruption.
Statement B about load balancing mode is incorrect. AC VRRP HSB operates in active/standby mode for redundancy, but does not provide load sharing functionality between the ACs. The focus is on providing a highly available standby AC, not distributing load.
In summary, Huawei’s AC VRRP HSB technology provides important high availability features like active/standby redundancy, real-time data backup, and automatic configuration synchronization to minimize downtime for WLAN networks. However, load balancing between ACs is not a capability of this protocol.
