Correct answer: VRRPv2.
Why this is the answer
VRRPv2 is the correct choice because it is an open-standard protocol, ensuring multi-vendor compatibility. It also supports both IPv4 and IPv6 (dual-stack) environments, making it suitable for modern network deployments. HSRP (Hot Standby Router Protocol) is a Cisco proprietary protocol, limiting multi-vendor interoperability. While HSRPv2 supports IPv6, its proprietary nature makes it less ideal for multi-vendor environments. GLBP (Gateway Load Balancing Protocol) is also Cisco proprietary and primarily focuses on load balancing, which isn't the core requirement for a multi-vendor, dual-stack FHRP. VRRPv1 only supports IPv4, making it unsuitable for dual-stack deployments.
