Implementing Cisco IP Switched Networks (CCNP SWITCH, legacy) — Question 162

Which First Hop Redundancy Protocol is an IEEE Standard?

Answer options

• A. GLBP
• B. HSRP
• C. VRRP
• D. OSPF

Correct answer:

Explanation

The correct answer is C. VRRP (Virtual Router Redundancy Protocol) is defined as an IEEE standard (IEEE 578). In contrast, HSRP (Hot Standby Router Protocol) is a Cisco proprietary protocol and GLBP (Gateway Load Balancing Protocol) is also Cisco proprietary, while OSPF (Open Shortest Path First) is a routing protocol, not a first hop redundancy protocol.
