Question 11
An administrator is configuring Playbooks and is concerned about adding or reducing CPU and memory resources to VMs.
Which two prerequisites should an administrator take into consideration when configuring the Playbooks? (Choose two.)
When configuring Playbooks to automate the scaling of CPU and memory resources for VMs, the administrator should consider the following prerequisites:
CPU can be added to a powered on VM if the guest OS supports it. This is also known as hot-plug CPU. The administrator should check the compatibility of the guest OS and the hypervisor before enabling this feature.For example, Windows Server 2019 supports hot-plug CPU on AHV, ESXi, and Hyper-V, but not on XenServer1.
Memory can be removed from a powered on VM if the guest OS supports it. This is also known as hot-unplug memory. The administrator should check the compatibility of the guest OS and the hypervisor before enabling this feature.For example, Linux supports hot-unplug memory on AHV, ESXi, and XenServer, but not on Hyper-V2.
VM must be powered off to add CPU if the guest OS does not support hot-plug CPU. This is also known as cold-plug CPU. The administrator should plan for the downtime required to power off and power on the VM after adding CPU.
VM must be powered off to reduce memory if the guest OS does not support hot-unplug memory. This is also known as cold-unplug memory. The administrator should plan for the downtime required to power off and power on the VM after reducing memory.Reference:Nutanix Multicloud Automation Administration (NMCAA), page 10;Nutanix Certified Professional - Multicloud Automation (NCP-MCA), section 3;Nutanix Support Portal - Guest OS Compatibility Matrix
Question 12
An end user for an application that has been assigned the Consumer role within the project has noticed multiple issues with a blueprint that need to be addressed. The decision has been made to bring the end user onto the team to be able to modify the blueprints for this project.
Using the concept of least privilege, what role should the end user be assigned?
The Developer role is the most appropriate role for the end user who needs to modify the blueprints for the project. The Developer role allows the user to create, edit, and delete blueprints and runbooks within the project, as well as launch and manage applications from the Marketplace. The Developer role does not have the privileges to create or manage projects, users, roles, or categories, which are reserved for the Project Admin role. The Consumer role only allows the user to launch and manage applications from the Marketplace, but not to modify the blueprints or runbooks. The Operator role allows the user to monitor and manage the infrastructure and applications within the project, but not to create or edit the blueprints or runbooks.

Question 13
Refer to the exhibit.
Saving the Calm Blueprint gives the validation error for VMware Blueprints shown in the exhibit.
What could be the cause of the error?
The error message in the exhibit indicates a mismatch between the number of network settings and the number of NICs on the VM.This is a common validation error when saving Calm Blueprints for VMware, where it is essential to ensure that these configurations match to avoid issues with VM deployment and operation1.Reference:1: Nutanix NCP-MCA Certification Exam Sample Questions2
Question 14
A company has a business-critical VM. The VM Utilization of CPU and memory differs from time to time, but can never be allowed to run out of resources. The administrator also wants to make sure that the VM is not over provisioned when not needed.
The administrator determines these requirements that have been validated and automated in a test environment should also apply for the production environment:
VCPU needs to be added when CPU Utilization been over 80% for 15 minutes.
Memory needs to be increased by 4 GB when utilization reaches 80%.
Return of over-allocated resources must not affect other business applications.
What can the administrator do with the least amount of effort to make sure the VM is always performant and returns resources when not required?
The easiest way to automate the VM utilization and resource allocation is to use a playbook that has been already tested and validated in a test environment. A playbook is a collection of actions that can be triggered by events or schedules to perform various tasks on the Nutanix platform. By importing the playbook from the test environment to the production environment, the administrator can save time and effort in creating a new playbook from scratch. The administrator only needs to adjust the values of the playbook parameters, such as the VM name, the CPU and memory thresholds, the VCPU and memory increments, and the notification settings, to match the production environment. The playbook can then be executed manually or automatically based on the desired frequency and conditions.

Question 15
How should an administrator enable Calm?
To enable Calm, the administrator needs to log on to Prism Central with a local ADMIN account and click Services -> Calm -> Enable. This will install the Calm service on Prism Central and allow the administrator to access the Calm UI and features. The other options are incorrect because they either refer to Prism Element, which is not the correct platform for Calm, or they involve unnecessary or incorrect steps.Reference: [Enabling and Accessing Calm | Nutanix Community] (https://next.nutanix.com/installation-configuration-23/enabling-and-accessing-calm-40191); [Nutanix Certified Professional - Multicloud Automation (NCP-MCA) Exam Blueprint Guide] (https://www.nutanix.com/content/dam/nutanix/resources/support/ds-ncp-mca.pdf), section 2.1.
Question 16
Where should an administrator check why a Playbook failed to grow the memory of a VM?
The Plays dashboard in Prism Central provides a centralized view of all the Playbooks that have been executed across the clusters registered with Prism Central. It shows the status, duration, and output of each Playbook run, as well as the details of the triggers, targets, and actions involved. An administrator can use the Plays dashboard to troubleshoot why a Playbook failed to grow the memory of a VM by checking the error messages, logs, and output of the Playbook run. The other options are not the correct places to check for Playbook failures, as they do not provide the same level of information and visibility as the Plays dashboard.Reference:Nutanix Certified Professional - Multicloud Automation (NCP-MCA) v6.5,Nutanix Certified Professional - Multicloud Automation (NCP-MCA) 6 Exam,Nutanix Exam NCP-MCA Topic 4 Question 20 Discussion
Question 17
An administrator is trying to delete a category, but the option is greyed out.
Which two conditions could be causing this issue? (Choose two.)
Categories are key-value pairs that you can use to tag and filter entities in Nutanix. There are two types of categories: system defined and user defined. System defined categories are built-in and cannot be deleted. User defined categories are created by the administrator and can be deleted if they are not used in any policy. Policies are rules that apply actions or restrictions to entities based on their categories. Flow policies are policies that control the network security and visibility of VMs. If a category is part of a flow policy, it cannot be deleted unless the policy is removed or modified. Therefore, the two conditions that could prevent an administrator from deleting a category are: the category is system defined, or the category is part of a flow policy.Reference:
Nutanix Support & Insights: This is the official Nutanix documentation for categories, where you can find information about the types, usage, and deletion of categories.

Question 18
An application team wants faster releases and starts an initiative to automate the entire database and application deployments.
The current manual process involves:
Creating virtual machines to host the databases and applications
Allocate right amount of storage for the database and applications
Deploy database software and create database
Schedule backup and recovery process for the database
Deploy applications
How can application releases be repeatedly deployed in the least amount of time?
The best way to automate the entire database and application deployments is to use a combination of Nutanix Calm and Nutanix Era. Nutanix Calm is a multicloud automation platform that allows you to create blueprints to deploy and manage infrastructure and applications across different cloud environments. Nutanix Era is a database management platform that allows you to provision, clone, patch, refresh, and restore databases in a simplified and automated way. By creating a Calm blueprint that deploys applications and calls Era APIs to automate database deployments, you can achieve faster and consistent releases, as well as reduce the manual effort and complexity involved in the process. You can also leverage the features of Calm and Era, such as self-service, governance, showback, backup, and recovery, to enhance the efficiency and security of your deployments.Reference:

Question 19
Refer to the exhibit.
A customer has decided to enable Calm Showback feature but started to receive an alert in Prism Central stating that Calm showback is not able to reach beam service.
Which two configuration items should the administrator check to ensure Calm can communicate with Beam? (Choose two.)
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.

Question 20
A director would like to have an up to date Cluster Efficiency Summary report emailed on the first of every month to keep management up to date on how the cluster is being utilized.
How could a playbook be configured to satisfy this request with the least human interaction?
A time trigger is a type of playbook trigger that allows the user to specify a schedule for running a playbook. This trigger is useful for automating tasks that need to be performed periodically or at a specific time. A manual trigger requires the user to initiate the playbook execution manually, which is not ideal for a recurring task. A report trigger is a type of playbook trigger that allows the user to run a playbook when a specific report is generated. However, this trigger does not guarantee that the report will be generated on the first of every month, as it depends on the report settings. A wait until day of month action is a type of playbook action that pauses the playbook execution until a specified day of the month. This action is unnecessary if the playbook already has a time trigger that specifies the desired schedule.
