Explanation

Option B (FALSE) is correct because on Huawei VRP, when you modify an export routing policy attached to a BGP neighbor, the system automatically triggers a soft reset outbound, causing BGP Update messages to be regenerated and resent to the neighbor without any manual intervention. This automation is a key VRP behavior designed to ensure policy changes take effect immediately.

Option A (TRUE) is incorrect because it assumes the administrator must manually issue a command (such as reset bgp or refresh bgp) after a policy change - this was true in older or less capable implementations, but VRP handles it automatically when the export direction policy is modified.

Memory tip: Think of VRP's export policy as "self-applying" - when you change the filter on the way out, VRP automatically re-advertises through that new filter. Only import policy changes typically require a manual inbound soft reset (since VRP cannot re-receive already-arrived routes without requesting them), so if the exam flips the direction to "import," the answer would reverse to TRUE.
