Question #51
An administrator is providing users with access to the company’s LOB applications through a VDI solution. The administrator received information that the company are going to hire 200 new employees who will be using these applications.
The environment is monitored by a third-party tool that notifies the administrator when the VDI solution is about to run out of capacity. This gives the administrator time to create additional resources and add them to the VDI solution.
What should the administrator use when creating a playbook to automate this?
- A . A trigger based on a REST API
- B . A trigger based on an email
- C . A trigger based on an event
- D . A trigger based on an alert
Correct Answer: C
C
Explanation:
The administrator should use a trigger based on an event when creating a playbook to automate the scaling of the VDI solution. An event trigger is a type of trigger that executes a playbook when a specific event occurs in the Nutanix environment or in a third-party system. An event trigger can be configured to listen to events from various sources, such as Prism alerts, Calm actions, or external webhooks. In this scenario, the administrator can use an event trigger to listen to the webhook from the third-party monitoring tool and execute a playbook that creates additional resources and adds them to the VDI solution.
A trigger based on a REST API is not the best option, because it requires the administrator to manually invoke the playbook using an API call. This is not as efficient or reliable as using an event trigger that automatically executes the playbook when the capacity threshold is reached.
A trigger based on an email is also not the best option, because it requires the administrator to configure an email server and a mailbox to receive the notification from the third-party tool. This adds complexity and overhead to the automation process and may not be as secure or timely as using an event trigger.
A trigger based on an alert is a valid option, but it depends on the availability and compatibility of the Prism alert system with the third-party tool. If the third-party tool can send alerts to Prism, then the administrator can use an alert trigger to execute the playbook. However, if the third-party tool does not integrate with Prism, then the administrator cannot use an alert trigger and has to use an event trigger instead.

Question #53
A company is new to automation and has infrastructure they would like to automate with Calm to provide standardized automation. The company also wants to create a Hybrid Cloud environment with their existing infrastructure which includes AHV, Azure, AWS, and a small legacy vSphere environment.
In which two locations can Calm be deployed? (Choose two.)
- A . vSphere Essential Edition
- B . VMware ESXi
- C . Nutanix AHV
- D . Any Public Cloud
Correct Answer: C D
C D
Explanation:
Nutanix Calm is a cloud-agnostic automation and orchestration solution that can be deployed on Nutanix AHV or any public cloud platform, such as AWS, Azure, or GCP. Calm can also manage applications across multiple cloud environments, including hybrid clouds. Calm cannot be deployed on vSphere Essential Edition or VMware ESXi, as these are not supported hypervisors for Calm. However, Calm can manage existing VMs on vSphere or ESXi clusters through the VMware provider.

- D . Microsoft Azure
- E . Amazon AWS
Correct Answer: CE
CE
Explanation:
According to the Nutanix Multicloud Automation Administration (NMCAA) course1, you can create and configure multi-VM blueprints for the Nutanix, AWS, VMware, GCP, and Azure providers. However, according to the Nutanix Certified Professional – Multicloud Automation (NCP-MCA) Exam Blueprint Guide2, the exam objectives only cover Nutanix and AWS as the providers for multi-VM blueprints. Therefore, the correct answer is C. Nutanix and E. Amazon AWS.

Question #55
What is the prerequisite for reducing the CPU and RAM memory allocation on a VM when using playbooks?
- A . VM must have NGT installed.
- B . Guest OS must support memory hot remove functionality.
- C . VM must be powered off.
- D . Guest OS must support CPU hot remove functionality.
Correct Answer: C
C
Explanation:
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.

Question #56
A company’s NOC personnel have a custom Python script they run manually by logging into each VM to fix a common issue across all of the corporate VMs. Management has no audit history of who is running the script or when it is occurring. The company has recently implemented Calm and management has asked its administrators to accomplish these tasks: Reduce the manual effort for the NOC personnel.
Ensure the process is repeatable across all applications.
Provide audit history for management of the actions.
Which two actions should the administrators take to accomplish these tasks? (Choose two.)
- A . Create a new Action, Add an Execute task with a script type of EScript, paste the custom script into the action
- B . View the Execution History tab under the Runbook page for audit purposes
- C . Create a new Runbook Add an Execute task with a script type of EScript paste the custom script into the action
- D . View the Audit tab under the Application view for audit purposes
Correct Answer: A, C
A, C
Explanation:
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.

Question #57
Which Calm feature provides the ability for administrators to approve Single or Multi-VM Blueprints for assignment to Projects?
- A . Application Manager
- B . Marketplace
- C . Projects
- D . Marketplace Manager
Correct Answer: D
D
Explanation:
The alert in Prism Central indicates that Calm showback is not able to reach the beam service. This could be due to network connectivity issues or incorrect configurations. The administrator should check the DNS configuration in Prism Central (Option A) to ensure that it is correctly configured to allow communication with the Beam service. Additionally, checking if Prism Element is configured with Proxy settings (Option C) is essential as it can also affect the communication between Calm and Beam. Pulse (Option B) and Flow (Option D) are not related to the Calm showback feature and do not impact its functionality.
