Explanation
A (TRUE) is correct because Huawei AR routers enable VRRP preemption mode by default, meaning a router with a higher priority will automatically reclaim the Master role when it recovers from a failure - no manual intervention required.
B (FALSE) is wrong because disabling preemption is a non-default configuration you must explicitly set with vrrp vrid <id> preempt-mode disable; out of the box, preemption is active.
Memory tip: Think of Huawei VRRP as "priority always wins" - the highest-priority router is aggressive about reclaiming Master status, which is the preemptive behavior enabled by default. If you need to suppress this (e.g., to avoid flapping), you have to explicitly turn it off.
