What is the purpose of FHRP?

To optimize router speed
To provide redundancy for the default gateway
To ensure static routing
To configure VLANs

The correct answer is: To provide redundancy for the default gateway

The purpose of the First Hop Redundancy Protocol (FHRP) is primarily to provide redundancy for the default gateway. FHRP allows multiple routers to work together to present a single virtual gateway IP address to the end devices on a network. By doing this, it ensures that if the primary router fails, another designated router can seamlessly take over the role of the default gateway without any disruption to the network communication. This redundancy is crucial in maintaining high availability and reliability within a network. End devices configure their default gateway to this single virtual IP, and they remain unaware of the backend changes happening in the router infrastructure, thereby enhancing responsiveness and continuity of service. The other options do not capture the primary function of FHRP. Optimizing router speed pertains to performance enhancement and load balancing rather than redundancy. Static routing is a method of setting fixed paths for data packets and does not inherently provide gateway redundancy. Configuring VLANs relates to creating distinct broadcast domains within a network, which is outside the scope of what FHRP addresses in terms of default gateway availability.
