Question 10/85
In the firewall hot standby scenario, in which of the following conditions will the local device proactively send VGMP packets?
Correct Answer: D
Comprehensive and Detailed Explanation:
VGMP (Virtual Group Management Protocol) is used in Huawei firewalls for hot standby and high availability.
* When is VGMP Activated?# When hot standby is enabled, firewalls must synchronize their states to maintain failover capability. ## VGMP sends packets periodically to check if the standby firewall is operational.
* Why Other Options Are Incorrect?# Priority increase (B): Does not trigger VGMP packets directly.
# Link detection timeout (C): Affects failover but does not initiate VGMP packets.# Hot standby being disabled (A): Disables VGMP, preventing packets from being sent.
Thus, the correct answer is D.
