Implementing Cisco Application Centric Infrastructure (DCACI) — Question 166

A customer must upgrade the Cisco ACI fabric to use a feature from the new code release. However, there is no direct path from the current release to the desired one. Based on the Cisco APIC Upgrade/Downgrade Support Matrix, the administrator must go through one intermediate release.

Which set of steps must be taken to upgrade the fabric to the new release?

Answer options

• A. 1. Upgrade the APICs to an interim release. 2. Upgrade the switches to an interim release. 3. Upgrade the APICs to the targeted release. 4. Upgrade the leaf and spine switches to the targeted release.
• B. 1. Upgrade the APICs to an interim release and then switches to an interim release. 2. When all switches are operational, upgrade leaf switches to the targeted release. 3. Upgrade the spine switches to the targeted release. 4. Upgrade the APICs to the targeted release.
• C. 1. Upgrade the APICs to an interim release. 2. Upgrade the leaf switches directly to the targeted release. 3. Upgrade the spine switches directly to the targeted release. 4. Upgrade the APICs to the targeted release.
• D. 1. Upgrade the APICs directly to the targeted release. 2. Upgrade the switches to an interim release. 3. When all switches are operational, upgrade the leaf switches to the targeted release. 4. Upgrade the spine switches to the targeted release.

Correct answer: A

Explanation

The correct answer is A because it follows the necessary steps to first upgrade to an interim release before proceeding to the targeted release, ensuring compatibility. Options B and D incorrectly suggest direct upgrades or do not follow the required sequence for all components, while option C skips necessary interim steps for the switches.
