Designing Cisco Data Center Infrastructure (DCID, legacy) — Question 71

Which NHRP features active and standby virtual gateways?

Answer options

• A. GLBP
• B. VRRP
• C. HSRP
• D. SSO
• E. NSF

Correct answer: A

Explanation

GLBP (Gateway Load Balancing Protocol) supports multiple virtual gateways, allowing for both active and standby configurations to enhance redundancy and load balancing. VRRP and HSRP also provide redundancy but do not actively balance load across multiple gateways like GLBP does. SSO (Stateful Switch Over) and NSF (Non-Stop Forwarding) are features related to switch failover and routing stability, not specifically about virtual gateways.
