Implementing Cisco Application Centric Infrastructure (DCACI) — Question 96

A recent set of changes by a Cisco ACI administrator corrupted the APIC cluster. The ACI engineer must restore the configuration of the previous day. The APIC nodes in the cluster can communicate but fail to connect with other networks. The administrator plans to overwrite the entire existing configuration with the backup configuration. Which set of actions accomplishes this task?

Answer options

• A. Restore using the last configuration on the factory-reset APIC. Use an import policy set to Best-effort.
• B. Roll back the configuration using a local snapshot. Use an import policy set to Atomic Replace.
• C. Roll back the configuration using a local snapshot. Use an import policy set to Best-effort Merge.
• D. Restore the configuration imported from an FTP server. Use an import policy set to Atomic.

Correct answer: B

Explanation

The correct answer is B because rolling back the configuration with a local snapshot ensures that the administrator can restore the previous state of the APIC effectively, and using the Atomic Replace policy guarantees that the configuration will be completely replaced without conflicts. The other options either do not utilize the correct rollback method or employ inappropriate import policies that may not achieve a full restoration.
