Correct answer: 1 second.
Why this is the answer
The correct answer is 1 second. The default advertisement interval for VRRP (Virtual Router Redundancy Protocol) on Cisco vEdge devices is 1 second. This interval dictates how frequently the master router sends VRRP advertisement messages to backup routers, ensuring they are aware of its operational status. If a backup router does not receive advertisements for a specified period (typically three times the advertisement interval), it assumes the master is down and initiates a failover. Options like 2, 3, or 5 seconds are not the default; while configurable, they would represent a change from the standard timer, potentially impacting failover times.
