Calm Runbooks are a way to automate workflows that span across multiple applications, services, or platforms. They can be used to perform actions such as provisioning, scaling, backup, restore, etc. Calm Runbooks can be added to the Library and reused in different Blueprints or Projects. A Post VM Delete Task is a special type of Task that is executed after a VM is deleted from a Blueprint. By creating Calm Runbooks for each of the manual steps required to decommission a VM, and adding them to the Library, the administrator can simplify the VM Decommission Process by consuming them inside of a Post VM Delete Task. This way, the application owners only need to delete the application from the Calm project, and the rest of the steps will be automated by the Runbooks. References:

To enable Quotas in Nutanix Self-Service (formerly Calm), the administrator should enable the Policy Engine. The Policy Engine manages and enforces various policies, including quotas for resource usage, to ensure that resource consumption stays within defined limits.

 If a Blueprint deployment fails, the administrator can use the Continue option in the Self-Service Portal to resume the deployment from the point of failure. This option will retry the failed task and continue with the remaining tasks in the Blueprint. The administrator does not need to delete the application or launch a new one, as this would waste time and resources. Saving the Blueprint will not automatically retry the task, as the Blueprint is only a template for the deployment.

The "Allow Collaboration" setting in a project enables a project administrator or user to view and manage VMs and applications of other users within the same project. This setting fosters collaboration and sharing of resources among users who are part of the same project.

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.

A Self-Service (formerly Calm) developer can find detailed and downloadable logs for analyzing a Blueprint deployment failure in the specific Application Audit tab. This tab provides insights and logs related to the deployment, helping to diagnose and resolve issues.

According to the Nutanix Multicloud Automation Administration (NMCAA) course1, one of the prerequisites for using X-Play to automate tasks on VMs is to have SSH enabled and configured on the target VMs. This allows X-Play to connect to the VMs and execute commands or scripts remotely. If the SSH service is not running on the VMs, then X-Play will fail to connect and perform the actions, resulting in the error message shown in the exhibit. The other options are not likely to cause this error, as they are either unrelated to X-Play (A and B) or not required for X-Play to work ©. References: Nutanix Multicloud Automation Administration (NMCAA) course

To ensure that checks can be implemented in a single task while creating an application using NDB (Nutanix Database Service), the administrator should run an eScript task. eScript tasks allow for more complex scripting and logic to be executed, including performing checks, handling conditions, and interacting with APIs.

In Nutanix's Multicloud Automation (formerly known as Calm), playbooks can be configured to respond to various conditions and events that occur within the infrastructure. If a VM, such as one named ORACLE, becomes CPU constrained, a playbook can be triggered to automatically add more virtual CPUs (vCPUs) to the VM. In addition, playbooks can integrate with various notification services such as Slack, allowing administrators to be informed of the changes being made.

Based on the provided options and according to Nutanix documentation, the correct action is that the playbook will add more vCPU and will send a Slack message. This ensures that the VM's performance can be adjusted dynamically while keeping the relevant personnel informed via Slack.
