Implementing Secure Solutions with Virtual Private Networks (SVPN) — Question 92

Which redundancy protocol must be implemented for IPsec stateless failover to work?

Answer options

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

Correct answer: C

Explanation

HSRP (Hot Standby Router Protocol) is essential for IPsec stateless failover as it allows for automatic router redundancy. The other options, such as SSO, GLBP, and VRRP, serve different purposes in network redundancy and do not specifically enable the stateless failover functionality required for IPsec.
