Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 581

Which technology enables a redundant supervisor engine to take over when the primary supervisor engine fails?

Answer options

• A. SSO
• B. FHRP
• C. graceful restart
• D. NSF

Correct answer: A

Explanation

SSO, or Stateful Switchover, is designed specifically to allow a redundant supervisor engine to seamlessly take over in the event of a primary engine failure, maintaining the state of the system. The other options, such as FHRP, graceful restart, and NSF, serve different functions related to network redundancy and service continuity but do not directly provide the same level of automatic failover for supervisor engines.
