You need to create an implementation plan for providing Layer 3 redundancy in your switched network. You included Hot Standby Routing Protocol (HSRP) as the protocol to avoid first-hop router failure. However, your supervisor suggests including Virtual Router Redundancy Protocol (VRRP) instead of HSRP in the implementation plan.
Which of the following statements is TRUE about the reasons for the suggested change in the implementation plan? (Choose two.)
- A: HSRP works only on Cisco routers and VRRP works on both Cisco and non- Cisco routers.
- B: HSRP works on both Cisco and non-Cisco routers and VRRP works only Cisco routers.
- C: HSRP-enabled routers need to be configured manually to preempt the active router and VRRP-enabled routers preempt it automatically.
- D: HSRP-enabled routers automatically preempt the active router and VRRP-enabled routers need to be configured manually to preempt the active router.
