Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 168

What are two considerations when using SSO as a network redundancy feature? (Choose two.)

Answer options

• A. requires synchronization between supervisors in order to guarantee continuous connectivity
• B. the multicast state is preserved during switchover
• C. must be combined with NSF to support uninterrupted Layer 3 operations
• D. both supervisors must be configured separately
• E. must be combined with NSF to support uninterrupted Layer 2 operations

Correct answer: A, C

Explanation

The correct answers, A and C, highlight the need for synchronization and the combination with NSF for uninterrupted operations across Layer 3. Options B, D, and E are incorrect because they either misrepresent the requirements for multicast state preservation or layer operations, or suggest unnecessary separate configurations for supervisors.
