Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 86

Which First Hop Redundancy Protocol should be used to meet a design requirement for more efficient default gateway bandwidth usage across multiple devices?

Answer options

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

Correct answer: A

Explanation

GLBP (Gateway Load Balancing Protocol) is designed specifically to allow multiple routers to share the load of handling traffic, thus improving bandwidth efficiency. HSRP and VRRP provide redundancy but do not balance the load across multiple gateways, while LACP is a protocol for link aggregation and not specifically for gateway redundancy.
