Refer to the exhibit. Refer to the exhibit. An engineer must implement HSRP between two WAN routers. In the event R1 tails and then regains operational status, it must allow 100 seconds for the routing protocol to converge before preemption takes effect. Which configuration is required?
Correct Answer: D
The configuration snippet shown is for HSRP (Hot Standby Router Protocol) on a Cisco router interface. It indicates that preemption is enabled with a delay sync of 100 seconds. This means if R1 fails and then regains operational status, it will wait for 100 seconds before attempting to become the active router again, allowing time for routing protocols to converge.
