Implementing Cisco Application Centric Infrastructure (DCACI) — Question 113

When a pre-provision immediacy is used, when is the policy downloaded to the Cisco ACI leaf switch?

Answer options

• A. The policy is downloaded and programmed in the hardware policy CAM when the change is implemented on the Cisco APIC.
• B. The policy is programmed in the hardware policy CAM when the policy is downloaded in the leaf software.
• C. The policy is programmed in the hardware policy CAM when the first packet is received through the data path.
• D. The policy is downloaded to the associated leaf switch software when the ESXi host is attached to a DVS.

Correct answer: A

Explanation

The correct answer is A because the policy is indeed downloaded and programmed in the hardware policy CAM at the moment the change is enacted on the Cisco APIC. The other options describe incorrect timings or processes for policy application, such as programming the CAM based on software downloads or packet reception, which do not align with pre-provision immediacy.
