True or False: The Virtual MAC option should be enabled during HA configuration to facilitate failover.

Enabling the Virtual MAC option during High Availability (HA) configuration is essential for facilitating seamless failover between hardware devices, such as firewalls. When High Availability is in place, one of the critical requirements is to maintain uninterrupted network service, which involves ensuring that devices can communicate effectively even when a failover occurs.

The Virtual MAC feature assigns a unique MAC address to the HA pair as a whole rather than to individual devices. This means that when one device in the HA pair fails, the primary MAC address remains constant, allowing the downstream devices (like switches or routers) to continue communicating without any disruption. The switch recognizes the Virtual MAC address and routes traffic to the newly active unit in a failover situation, thus eliminating the need for devices to relearn the MAC address. This significantly speeds up the process of failover and maintains network stability.

Without enabling the Virtual MAC option, the switch would still be reaching out to the failed device's physical MAC address, which may lead to delays as it realizes the primary device is down and tries to reroute the traffic. Therefore, enabling Virtual MAC proactively addresses any potential issues that could arise during failover, ensuring that network services remain available to users.
