Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 189

Which First Hop Redundancy Protocol maximizes uplink utilization and minimizes the amount of configuration that is necessary?

Answer options

• A. GLBP
• B. HSRP v2
• C. VRRP
• D. HSRP v1

Correct answer: A

Explanation

GLBP (Gateway Load Balancing Protocol) is designed to maximize the utilization of uplinks by allowing multiple gateways to be active simultaneously. In contrast, HSRP and VRRP primarily focus on failover capabilities rather than load balancing, and HSRP v1 lacks some of the enhancements present in newer versions, making GLBP the best choice for both efficiency and minimal configuration.
