Answers
D.
During the initial VSX configuration, the system-mac is assigned with a fixed MAC based on VSX ID.
Suggested answer: D

Explanation:

The system-mac command is used to configure a fixed MAC address for the VSX system. This MAC address is used as the source MAC address for all routed traffic from the VSX node.The system-mac command is highly recommended for preventing traffic disruptions when the primary VSX switch restores after the secondary VSX switch, such as during a primary switch hardware replacement or a power outage2. During the initial VSX configuration, the system-mac is assigned with a fixed MAC based on VSX ID.The system-mac command can be used to change this default MAC address if needed2. Therefore, answer D is correct.
