Troubleshooting Cisco Data Center Infrastructure (DCIT) — Question 34

A network engineer is implementing the Cisco ACI Fabric and notices that the Leaf-1 switch is registered, has an assigned name, but is displayed as inactive in the APIC. After further investigation, it became clear that the leaf switch was recently moved from another Cisco ACI environment. Which action resolves the problem?

Answer options

• A. Clean reload the Leaf-1 switch
• B. Define the new TEP address for Leaf-1
• C. Change the clock offset from low to high between apic 1 and Leaf-1
• D. Modify the ISIS interface peering IP address between apic 1 and Leaf-1

Correct answer: A

Explanation

The correct answer is A, as performing a clean reload of the Leaf-1 switch will reset its state and allow it to re-register properly in the APIC, especially after being moved from another environment. Options B, C, and D address configuration issues that may not necessarily resolve the inactive state if the switch is not properly initialized in the new environment.
