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: https://www.cisco.com/c/en/us/td/docs/solutions/Enterprise/Campus/HA_campus_DG/ hacampusdg.html#wp1107923
"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 secondes so we take the higher delay available..

C. EIGRP queries will only increase the convergence time when there are no EIGRP stubs designed in the network
D. EIGRP queries will be stuck-in-active if there are no EIGRP stubs
