Implementing and Operating Cisco Data Center Core Technologies (DCCOR) — Question 188

Which two features are used to allow a nondisruptive upgrade for the ISSU process? (Choose two.)

Answer options

• A. graceful restart
• B. advanced services license
• C. nonstop forwarding
• D. connectivity management processor
• E. stateful switchover

Correct answer: C, E

Explanation

The correct answers, C (nonstop forwarding) and E (stateful switchover), are crucial for maintaining network operations during an upgrade. Nonstop forwarding ensures that traffic continues to flow without interruption, while stateful switchover allows for the active state of sessions to be preserved. The other options, while related to network operations, do not specifically support nondisruptive upgrades in the ISSU process.
