Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 392
You need to implement a First Hop Redundancy Protocol (FHRP) in a dual stack (IPv4 and IPV6) environment that utilizes devices from multiple different vendors. Which protocol best meets these needs?
Answer options
- A. HSRP
- B. GLBP
- C. VRRPv1
- D. VRRPv2
Correct answer: D
Explanation
VRRPv2 is the most suitable choice as it supports both IPv4 and IPv6 in a multi-vendor scenario, providing redundancy. HSRP is Cisco-specific, making it less ideal for a multi-vendor setup. GLBP offers load balancing but may not be as universally supported. VRRPv1 lacks support for IPv6, which is critical in a dual stack environment.
