An administrator is configuring a new Self-Service project. There is a Playbook targeting VMs with the respective CalmProject category that automates post-deployment tasks (such as tagging, monitoring and sending notifications). After assigning the blueprint and users, the administrator wants to validate that the Project and Playbook configurations are functioning as created before user deployment begins. Which two steps should the administrator take to complete this task? (Choose two.)

Answer options

A: Run the Playbook manually using the "Execute" option in Prism Central to test its logic.

B: Run the Playbook manually using the "Execute on behalf of" option in Prism Central to test its logic. Correct answer

C: Deploy the blueprint associated with the Marketplace and verify that the Playbook executes as expected.

D: Deploy the blueprint associated with the Project and verify that the Playbook executes as expected. Correct answer

Correct Answer:

B. Run the Playbook manually using the "Execute on behalf of" option in Prism Central to test its logic.; D. Deploy the blueprint associated with the Project and verify that the Playbook executes as expected.

Explanation

To be certain that both the Self-Service project scoping and the post-deployment Playbook work, the administrator should:
• first manually fire the Playbook with “Execute on Behalf Of”, selecting a VM that carries the CalmProject category. This runs every task exactly as the Playbook would when it is later triggered automatically, validating its logic and variable resolution.
• then deploy the blueprint from inside the same Project. The resulting VM(s) inherit the CalmProject category, so the Playbook should trigger automatically; observing this confirms that the Project/blueprint binding and Playbook trigger are correctly configured before opening access to users.

Why Incorrect

A. “Execute” lacks entity context; tasks that depend on VM-level variables or categories will not be validated.
C. Deploying the Marketplace-level blueprint bypasses the Project context; VMs will not receive the Project category, so the Playbook trigger cannot be confirmed.
