Implementing Cisco SD-WAN Solutions (ENSDWI) — Question 64

A network administrator is configuring VRRP to avoid a traffic black hole when the transport side of the network is down on the primary device. What must be configured to get the fastest failover to standby?

Answer options

• A. OMP tracking
• B. higher group ID number
• C. prefix-list tracking
• D. lower timer interval

Correct answer: C

Explanation

Configuring prefix-list tracking allows for monitoring specific prefixes and can trigger a failover more rapidly when issues arise. The other options either do not directly relate to the speed of failover or do not provide the same level of responsiveness in the event of a link failure.
