NEW QUESTION # 24
After an application is no longer needed, a user puts in a ticket to delete the VM. The administrator finds the VM in Prism Central and deletes it, but then realize that it was a Self-Service (formerly Calm) managed VM.
When the administrator attempts the application in Self-Service using the Delete action, it fails because the Substrate cannot be found.
How would the administrator delete the application from management?
- A. Execute the Soft Delete action to ignore the provide substrate.
- B. Execute the Delete action again, the second run will ignore the error.
- C. The platform Sync Service will remove the application.
- D. In the Audit view of the application, click Retry
Answer: A
Explanation:
When a VM managed by Self-Service (formerly Calm) is deleted manually from Prism Central, the associated application in Self-Service cannot be deleted using the standard delete action because the substrate is no longer present. In this scenario, the administrator should use the "Soft Delete" action in Self-Service, which will remove the application from management without requiring the substrate to be present.

NEW QUESTION # 25
How would a task be listed in the Library?
- A. Go to the Library in Self-Service and Create a new task.
- B. Create a new task in GitHub.
- C. Publish the task from a Blueprint or Runbook.
- D. Upload the script from the Projects view.
Answer: C
Explanation:
To make a specific task available for reuse across other blueprints and runbooks, an administrator can publish the task to the Task Library.
While working within the Blueprint or Runbook editor, an administrator can select a specific task they have configured. In the configuration pane for that task, there is an option to"Publish to Library". Selecting this saves the task (including its script and settings) to the central Task Library. Once published, the task appears in the Library list and can be imported into other blueprints or runbooks, ensuring consistency and reducing duplicated effort.
NEW QUESTION # 26
Which role is required to create a playbook?
- A. Prism Viewer
- B. Prism Admin
- C. Developer
- D. Self-Service Admin
Answer: B
Explanation:
Creating and managingPlaybookswithin the Intelligent Operations (X-Play) feature of Prism Central requires an administrative role with sufficient privileges to define system-wide automation rules.
* Prism Admin:ThePrism Admin(or Super Admin) role is explicitly required to create, edit, enable, and manage Playbooks. This role grants full control over the Intelligent Operations module.
* Prism Viewer (A):This role has read-only access and can view Playbooks but cannot create or modify them.
* Self-Service Admin (D):This role is specific to the Self-Service (Calm) application and its blueprints
/projects, not the X-Play automation engine in Prism Central.
NEW QUESTION # 27
Exhibit.
The user would like to take a snapshot, expand the vDisk and get the result with a Slack message triggered by a pipeline CI/CD.
What trigger should be used?
- A. REST API
- B. Manual
- C. Alert
- D. Webhook
Answer: D
Explanation:
To trigger a series of actions (taking a snapshot, expanding the vDisk, and sending a Slack message) from a pipeline CI/CD, the appropriate trigger to use is "Webhook." Webhooks allow external systems, such as CI/CD pipelines, to trigger playbooks in Nutanix Calm via HTTP requests, making them suitable for integrating with CI/CD tools.

NEW QUESTION # 28
An administrator receives the following error while running a script through Calm on VM:
Which two conditions could cause this issue? (Choose two.)
- A. The VM port is not allowed by the firewall.
- B. The credentials have insufficient permissions.
- C. The VM is still in the boot process.
- D. There is an error in the script.
Answer: A,B
Explanation:
The error "Connection refused" can occur due to several reasons but in the context of running a script through Calm on VM, it is most likely caused by firewall restrictions or insufficient permissions. Option A suggests that the VM port is not allowed by the firewall, meaning that the firewall settings are preventing the connection. This could be because specific ports needed for the script to run are being blocked. Option B indicates that the credentials have insufficient permissions, meaning that the user or system trying to execute the script does not have the necessary permissions to establish a connection. Option C is unlikely because the VM should be ready before the script is executed. Option D is possible but not specific enough to explain the connection issue. References: You can find more information about this topic in the following sources:

NEW QUESTION # 29
An administrator has built a Playbook to run a Powershell script in a VM when a specific alert is generated.
Several days later, the alert is generated, but the script does not execute and there are no Plays recorded for the Playbook.
What is causing this issue?
- A. The Playbook was never enabled.
- B. The version of Playbooks is not correct for the version of Prism Central.
- C. The script executed, but closed with an error code.
- D. The path to the script was not correct.
Answer: A
Explanation:
A Playbook is a set of actions that are triggered by an event or a schedule. To run a Playbook, it must be enabled first. If a Playbook is not enabled, it will not respond to any events or schedules, and no Plays will be recorded for it. Therefore, the most likely cause of the issue is that the administrator forgot to enable the Playbook after building it.

NEW QUESTION # 30
An administrator has created a Runbook to periodically reboot virtual machines and update their credentials.
However, when executing the Runbook, the administrator notices that the credential-setting process consistently fails.
What tasks should the administrator include in the Runbook to meet this objective?
- A. VM restart, Add Delay, Add new credential
- B. HTTP task, VM power on, create Replica
- C. Pre-Create, VM power cycle, Set Endpoint
- D. VM Power off, error handling, while loop
Answer: A
Explanation:
When creating a Runbook that involves power cycling a VM (Restart), there is a gap in connectivity while the Guest OS reboots and network services initialize.
If the Runbook moves immediately from the "VM Restart" task to the "Add new credential" task (which likely uses SSH or PowerShell to connect to the VM), the connection will fail because the VM is not yet accessible.
To correct this, the administrator must insert a Delay task between the restart and the configuration step.
The sequence should be:
* VM Restart:Initiates the reboot.
* Delay:Pauses the runbook execution for a set duration (e.g., 60-120 seconds) to allow the OS to boot.
* Add new credential:Executes the script once the VM is back online.
NEW QUESTION # 31
Which is a valid Endpoint in Self-Service?

Answer: C
NEW QUESTION # 32
What are the two Calm SaaS API Key components? (Choose two.)
- A. Name
- B. JSON file
- C. SaaS Token
- D. Token
Answer: A,D
Explanation:
The Calm SaaS API key consists of two components: name and token. The name component is analogous to the ID or username you provide when you configure your Calm tunnel client VM to establish the tunnel connection. The token component is analogous to the password portion of the HTTP basic authentication. The Calm SaaS API key is used along with the Calm APIs and Calm DSL to access Calm. The API key file that you download will have the name and token components in the JSON format. Reference: Nutanix Support & Insights

Which action should an administrator use to request a static IP address from an IPAM solution?
- A. Create
- B. Pre-create
- C. Guest Customization
- D. Profile
Answer: B
Explanation:
When integrating with an IP Address Management (IPAM) solution within Nutanix Calm, an administrator would use a 'Pre-create' task to request a static IP address. This task is performed before the actual creation of the VM, ensuring that the IP address is allocated and can be assigned during the VM's creation process. Profiles (A) are used to define deployment environments, Guest Customization (C) is used for configuring the OS settings, and Create (D) is typically the task for provisioning the actual VM, not for requesting an IP.

NEW QUESTION # 42
An administrator has noticed an increasing number of inactive VMS being left powered on within the environment over the course of OS migrations, using Playbooks, which two Actions should the administrator use to start documenting which VMS are marked as inactive to take future Automated actions on? (Choose two.)
- A. Send an Email with the Source Entity Name Parameter in the body.
- B. Assign the VMS to an Inactive:VM Category as an Action.
- C. Trigger Playbook on Alert with the Inactive VM Alert Policy.
- D. Trigger Playbook on Powered Off VM for all applicable VMS.
Answer: B,C
Explanation:
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. Reference:

When configuring Calm to use Kubernetes as a provider, what two options does an administrator have as Kubernetes types? (Choose two.)
- A. Vanilla
- B. OpenShift
- C. Rancher
- D. Karbon
Answer: A,D
Explanation:
When configuring Calm to use Kubernetes as a provider, the administrator can choose between two Kubernetes types: Karbon and Vanilla. Karbon is Nutanix's own Kubernetes distribution that is integrated with Prism and AHV. Vanilla is any other Kubernetes distribution that is not Karbon, such as OpenShift, Rancher, or EKS. The administrator needs to provide the Kubernetes API endpoint and credentials for the Vanilla type, while the Karbon type is automatically discovered by Calm.

NEW QUESTION # 45
An administrator has been tasked with automating the optimization of plays with the autopilot feature.
What must the administrator be aware of before configuring autopilot?
- A. Autopilot will only attempt to apply the playbook a single time
- B. Autopilot never waits for approvals.
- C. Autopilot feature only applies to metric-based alerts as triggers.
- D. Autopilot only applies to new playbooks.
Answer: B
Explanation:
Autopilot is a feature of Nutanix Calm that allows the administrator to automate the execution of playbooks based on predefined conditions or triggers. Autopilot can optimize the performance, availability, and cost of applications by applying the appropriate actions in response to events or metrics. Before configuring autopilot, the administrator must be aware of the following limitations12:
* Autopilot never waits for approvals. This means that the administrator must ensure that the playbooks are tested and verified before enabling autopilot. Autopilot will execute the playbooks without any human intervention or confirmation.
* Autopilot feature only applies to metric-based alerts as triggers. This means that the administrator can only use metrics from the Nutanix Prism Central or the Nutanix Karbon clusters as the conditions for triggering the playbooks. Autopilot does not support other types of triggers such as schedules, webhooks, or manual triggers. References: Nutanix Certified Professional - Multicloud Automation (NCP-MCA) Exam Blueprint Guide, page 10; Nutanix Calm SaaS User Guide, section 4.3.

What is causing the error message?
- A. executing the not have privileges.
- B. The VM is missing Nutanix Guest Tool.
- C. The SSH Service is not running on the VMs.
- D. The VM is Off.
Answer: C
Explanation:
The error message "INTERNAL_ERROR: ErrorCode: 9" typically indicates an issue with the SSH service on the VMs.
In this context, where a playbook is being executed to shut down Linux VMs, it's essential that the SSH service is running to allow for remote management and execution of commands.
If the SSH service isn't running, the playbook won't be able to execute commands on the VMs, leading to an internal error.
