* Geographic Redundancy in SD-WAN Controllers:
* Huawei's SD-WAN solution provides geographic redundancy to ensure high availability and disaster recovery.
* Analysis of Each Statement:
* Option A:This is correct. The active and standby clusters share the same domain name or IP address, enabling seamless failover during an active/standby switchover.
* Option B:This is correct. Geographic redundancy requires the active and standby clusters to have the same number of nodes to ensure balanced performance.
* Option C:This is correct. Huawei's SD-WAN solution supports only one active cluster and one standby cluster for geographic redundancy.
* Option D:This is incorrect. While the active and standby clusters synchronize data in real time, only the active cluster provides services. The standby cluster remains idle until a failover occurs.
* Conclusion:The FALSE statement is Option D.
