  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..

  A. first hop redundancy protocol.
  B. Single uplinks between access and distribution switches.
  C. Layer 2 links between access switches.
