Implementing Secure Solutions with Virtual Private Networks (SVPN) — Question 38

Which technology works with IPsec stateful failover?

Answer options

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

Correct answer: B

Explanation

HSRP (Hot Standby Router Protocol) is designed to provide high availability by allowing multiple routers to work together as a single virtual router, making it suitable for IPsec stateful failover. GLBP, GRE, and VRRP do not support stateful failover in the same manner as HSRP, which is specifically designed for this purpose.
