Troubleshooting Cisco Data Center Infrastructure (DCIT) — Question 10

An IOM fails during a firmware upgrade and is unresponsive. Which action recovers the module?

Answer options

• A. Restore the Cisco UCS Manager configuration from backup.
• B. Roll back to the previous firmware.
• C. Reinstall the firmware using Auto Install.
• D. Reset the faulty module from the peer IOM.

Correct answer: B

Explanation

The correct answer is B, as rolling back to the previous firmware can restore functionality to the IOM that failed during the upgrade. Options A and C do not directly address the unresponsive state caused by the failed upgrade, and D might not be effective if the peer IOM is also impacted or if the issue is specific to the firmware upgrade.
