A Branch Condition is a type of action in X-Play that allows you to create conditional logic based on the output of a previous action or a custom expression. A Branch Condition can have multiple branches, each with a different condition and a different set of actions to execute if the condition is met. The minimum number of actions required in a Branch Condition is two: one for the condition itself, and one for the action to perform if the condition is true. If the condition is false, the Branch Condition will skip to the next action in the Playbook. You can add more branches to a Branch Condition, but you cannot have less than two. References: Nutanix Calm: Playbooks - Read the Docs and Nutanix Calm: Branch Condition - Read the Docs.

To reduce the manual effort for the NOC personnel, the administrators can create a new Action that contains the custom Python script as an Execute task with a script type of EScript. This will allow the NOC personnel to run the script on any VM from the Calm UI or API without logging into each VM. To ensure the process is repeatable across all applications, the administrators can create a new Runbook that contains the same Action and assign it to the relevant Projects. This will enable the NOC personnel to run the script on multiple VMs across different applications in a single workflow. To provide audit history for management of the actions, the administrators can view the Execution History tab under the Runbook page for audit purposes. This will show the details of each Runbook execution, such as the status, duration, user, and logs. Alternatively, the administrators can also view the Audit tab under the Application view for audit purposes. This will show the history of all actions performed on the application, such as launch, update, delete, and run actions. References: Nutanix Certified Professional - Multicloud Automation (NCP-MCA) Exam Blueprint Guide, page 18, section 4.2.1. 

To reduce the CPU and RAM memory allocation on a VM using playbooks, the VM must be powered off. This is because the operation of reducing CPU and memory allocation cannot be performed on a running VM without causing instability or potential crashes.
