The most likely reason for this behavior is that the developer created a post-create task for reserving the IP address. A post-create task is executed after the VM is created and powered on, which means that the VM already obtained a DHCP IP address before the task is run. To reserve the IP address in IPAM as part of the deployment process, the developer should create a pre-create task instead. A pre-create task is executed before the VM is created and powered on, which allows the task to reserve the IP address in IPAM and assign it to the VM. References: Nutanix Certified Professional - Multicloud Automation (NCP-MCA) Exam Blueprint Guide, page 15; Nutanix NCP-MCA Questions, question 57.

An event trigger is a type of trigger that can be used to execute a playbook when a specific event occurs in the Nutanix platform. An event trigger can be configured with various parameters, such as the event type, the target VM, the target VM category, the target project, and the target user. In this scenario, the administrator wants to be notified when a subset of VMs within the Environment:Dev category is restored from snapshot. Therefore, the event trigger should have the following parameters:

Event type: Snapshot Restoration. This is the event that indicates a VM has been restored from a snapshot.

Target VM: VMS in Environment: Dev. This is the filter that specifies which VMs are relevant for the trigger. By selecting VMS in Environment: Dev, the trigger will only apply to the VMs that belong to the Environment:Dev category.

Other parameters: These can be left as default or customized as needed.

To run a blueprint deployment and tasks in a different Prism Central instance than the one running Self-Service (formerly Calm), the administrator should add the remote Prism Central instance as an account. This configuration allows Self-Service to interact with multiple Prism Central instances, enabling the management and deployment of blueprints across different environments.

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. 

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:

 A macro is a placeholder for a value that is resolved at runtime. Macros can be used to reference various Calm objects, such as variables, secrets, credentials, tasks, and services. The correct syntax for using a macro within a Calm blueprint is @@{calm.object}(@@, where calm.object is the name of the object to be referenced. For example, @@{username}(@@ would resolve to the value of the username variable at runtime. The other options are incorrect syntaxes for macros and would not be resolved by Calm. References: Nutanix Certified Professional - Multicloud Automation (NCP-MCA) v6.5, Nutanix Certified Professional - Multicloud Automation (NCP-MCA) 6 Exam, Nutanix Certified Professional - Multicloud Automation

Categories are a way of organizing and managing resources in Nutanix Calm. Categories can be used to define access policies, filter resources, and group applications. By creating and assigning the Linux OS Category to the newly-created VM, the administrator can grant access to the OS Team based on their Active Directory Group membership. The OS Team can then use the web SSH console to access the Linux VM from the Calm UI.

To automate routine tasks such as acknowledging alerts, generating reports, and looking up cluster details on a set interval, the administrator should implement a Time Trigger. Time Triggers allow actions to be scheduled to run at specific times or intervals, ensuring consistent execution without manual intervention.

The administrator should assign the VMs to an Inactive:VM category as an action and trigger a playbook on alert with the Inactive VM alert policy. By doing this, they can create a custom category to group and identify the inactive VMs and use a custom alert policy to trigger a playbook that can perform automated actions on them, such as powering them off, deleting them, or sending notifications. This is based on the general practices in managing VMs in a multicloud environment, as well as the specific features and requirements of Nutanix X-Play and Nutanix Calm. References:

To automate the task of growing vDisks on multiple classes of VMs using Nutanix Playbooks, the administrator should follow these steps:

Create a custom Alert Policy:

Create an alert policy that triggers when the server's disk usage reaches 85% or above. This ensures the playbook is triggered based on the specified threshold.

Select Alert as the trigger:

Set the alert created in step 1 as the trigger for the playbook. This ties the alert condition to the execution of the playbook.

Select Email Action with custom message:

Add an action to send an email notification. This email should be sent prior to any work being started, to inform relevant stakeholders about the impending vDisk growth operation.

Add Action to Grow vDisks:

Add the action to grow the vDisks on the VMs. This step should include the necessary script or task that performs the vDisk growth operation on the specified VMs.

Based on the requirements and steps, the playbook should be structured as follows:

Step 1: Create a custom Alert Policy

Define the alert policy with the condition that disk usage on the VMs reaches 85% or higher.

Step 2: Select Alert as the trigger

Use the alert policy created in Step 1 as the trigger for the playbook.

Step 3: Select Email Action with custom message

Add an email action to notify relevant stakeholders before the vDisk growth task is initiated.

Step 4: Add Action to Grow vDisks

Include the necessary action to grow the vDisks on the VMs as required.

This structure ensures that the playbook is dynamically responsive to changes in server usage, sends notifications prior to execution, and performs the required vDisk growth operation automatically.
