What is the primary purpose of the first hop redundancy protocols?
The correct answer is D. to ensure high availability of the network by providing a transparent fail-over at the active gateway. First hop redundancy protocols (like HSRP, VRRP, and GLBP) are designed to provide high availability for the default gateway in a network. They allow multiple routers to work together to present a single virtual router (or default gateway) to the hosts on a local network. If the

Explanation
First hop redundancy protocols (like HSRP, VRRP, and GLBP) are designed to provide high availability for the default gateway in a network. They allow multiple routers to work together to present a single virtual router (or default gateway) to the hosts on a local network. If the active gateway fails, the FHRP will automatically failover to a backup router without requiring any changes on the client side. This transparency is crucial for maintaining uninterrupted network
