QUESTION 33
An HSRP design requirement states that preemption must be enabled for the active switch, which is a Cisco 4507R. Assume a boot time of 300 seconds.
Which setting of the preemption delay timer minimizes the loss of traffic?
A. 50 seconds
B. 100 seconds
C. 150 seconds
D. 200 seconds
Answer: D
Explanation:

The recommended best practice is to measure the system boot time, and set the HSRP preempt delay statement to 50 percent greater than this value. This ensures that the HSRP primary distribution node has established full connectivity to all parts of the network before HSRP preemption is allowed to occur”-> We can’t choose 450 seconds so we take the higher delay available..
