CCIE Data Center (legacy) — Question 20

An administrator is replacing a fabric interconnect. The failed fabric interconnect was FI-A and was master at the time of failure. Which process brings the replacement fabric interconnect into the cluster?

Answer options

• A. Connect the new FI-A to the management network and the Layer 1/Layer 2 links to the existing FI-B. Use the Full State Backup file to restore the configuration when prompted at the console.
• B. Connect the new FI-A to the management network and the Layer 1/Layer 2 links to the existing FI-B. Let the system sync with FI-B when prompted at the console.
• C. Connect the FI-A to the management network and the Layer 1/Layer 2 links to the existing FI-B. Use the All Configuration backup file to restore the configuration through Cisco UCS Manager GUI.
• D. Connect the new FI-A to the management network only. Use the Full State Backup file to restore the configuration through Cisco UCS Manager GUI. Connect the Layer 1/Layer 2 cables.
• E. Connect the new FI-A to FI-B using the Layer1/Layer 2 cables only. Sync the configuration when prompted. Connect the management interface when the configuration is synced.

Correct answer: D

Explanation

The correct answer is D because it specifies connecting the new FI-A to the management network first and restoring the configuration through the Full State Backup file, which is essential for a proper setup. Options A and C incorrectly suggest using the console or the All Configuration backup, which are not optimal for this scenario. Option B does not mention restoring the configuration, which is crucial after replacing a master interconnect, while Option E delays management interface connection until after sync, which is not the best practice.
