Policy routing can be associated with IP-Link or BFD to determine the availability of policy routing based on the status check results of IP-Link or BFD.

The correct answer is A. True. A is correct because modern network operating systems (such as Huawei VRP) support binding policy routing to IP-Link or BFD tracking objects, so that when the tracked link or session goes down, the policy route is automatically disabled or switched to a backup path - making…

Explanation

A is correct because modern network operating systems (such as Huawei VRP) support binding policy routing to IP-Link or BFD tracking objects, so that when the tracked link or session goes down, the policy route is automatically disabled or switched to a backup path - making routing decisions dynamic and failure-aware.

B is wrong because it assumes policy routing operates in isolation without any reachability-detection integration, which is not the case; this integration is a documented and commonly tested feature in enterprise/carrier routing platforms.

Memory tip: Think of IP-Link/BFD as a "health check sensor" attached to a policy route - just like a traffic light that only lets cars through when conditions are safe, the policy route only stays active when its associated IP-Link or BFD session reports the path is up.
