                                                      Answer: A


                                                      NEW QUESTION # 266
                                                      In the firewall hot standby scenario, in which of the following conditions will the local device proactively send VGMP packets?

                                                      Answer: A

                                                      Explanation:
                                                      Comprehensive and Detailed
                                                      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.
