Free Practice Questions for Nutanix NCP-MCA Exam

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.

Calm integrates natively with AWS and AHV as providers. A provider is a cloud platform or infrastructure that hosts the application VMs or services. Calm supports various providers such as Nutanix, AWS, Azure, GCP, VMware, and Kubernetes. AWS and AHV are two of the most commonly used providers in Calm, as they offer scalability, flexibility, and cost-efficiency for deploying applications. References: Nutanix Certified Professional - Multicloud Automation (NCP-MCA) Exam Blueprint Guide, page 11; Nutanix Calm User Guide, section 3.1.

The warnings in the exhibit indicate that certain variables are missing or incorrectly defined. To resolve these warnings, the administrator should:

Create the variable under the action: Ensure that the necessary variables are defined in the scope of the action where they are required.

Create an add_worker_node_count variable: Specifically, the blueprint requires a variable named add_worker_node_count. This variable should be defined and given an appropriate value to ensure the action can execute properly.

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:

The PagerDuty Integration service allows you to create and manage incidents in PagerDuty based on events in Nutanix X-Play. To configure the PagerDuty Integration service, you need to provide the following information:

Service Name: The name of the PagerDuty service that you want to integrate with X-Play.

API Key: The API key generated from the PagerDuty service settings.

Plays: The plays that you want to trigger incidents in PagerDuty. You can select one or more plays from the list of available plays in X-Play. You can also specify the incident priority, escalation policy, and alert details for each play.

Alert Grouping: (Optional) The alert grouping strategy that you want to use for the PagerDuty incidents. You can choose from the following options:

Intelligent: PagerDuty will group alerts based on their content and context.

Time: PagerDuty will group alerts based on the time they are received.

None: PagerDuty will not group alerts and create a new incident for each alert. References: Nutanix Multicloud Automation Administration (NMCAA) course, Nutanix Certified Professional - Multicloud Automation (NCP-MCA) 6.5 Exam Guide, Process Automation | PagerDuty

Alerts are a way of monitoring the health and performance of the Nutanix cluster and the VMs running on it. Alerts can be triggered by various metrics, such as CPU usage, memory usage, disk space, network traffic, etc. Alerts can also be configured to send notifications to the administrator or other recipients via email, Slack, PagerDuty, etc. To satisfy the request from the Accounting department, the administrator should create an Alert with the following settings:

Trigger: CPU Usage (%) > 90 OR Memory Usage (%) > 90

Scope: VM

Category: LOB:Accounting

Notification: Email to accounting@company.com This way, the Alert will only apply to the VMs that belong to the Accounting department, and will send an email notification to the Accounting department when any of their VMs exceed the specified thresholds. References: Nutanix Multicloud Automation Administration (NMCAA), page 9; Nutanix Certified Professional - Multicloud Automation (NCP-MCA), section 1; [Nutanix Prism Central Guide - Alerts]

This solution meets the requirements of creating a multicloud, three-tier application using Calm. It ensures that each tier of the application has a redundant copy running on both Nutanix and AWS, and that the application can tolerate either a cloud provider outage or a local Nutanix cluster outage. The other options do not provide full redundancy for each tier, or require manual intervention to create the AWS instances. References: Nutanix Certified Professional - Multicloud Automation (NCP-MCA) Exam Blueprint Guide, page 10; Nutanix Multicloud Automation Administration (NMCAA) Course, Module 5: Blueprints.

A Playbook is a feature of Nutanix Calm that allows you to automate tasks based on certain triggers or events. You can use a Playbook to create a workflow that monitors the storage capacity of the cluster and sends an email notification to the IT Director when the capacity reaches a certain threshold. You can also use the Playbook to generate a forecast report that shows the projected storage usage and availability based on historical data and trends.

The port 5986 is used for PowerShell Remoting over HTTPS, which is a secure way of executing PowerShell commands on a remote Windows VM. Calm uses PowerShell Remoting to run scripts on Windows VMs as part of the blueprint actions. Therefore, the port 5986 needs to be opened on the VM firewall to allow the communication between Calm and the VM. The other ports are not related to PowerShell Remoting, as they are used for SQL Server (1433), Remote Desktop Protocol (3389), and PowerShell Remoting over HTTP (5985). References: Nutanix Certified Professional - Multicloud Automation (NCP-MCA) 6.5 Exam Blueprint Guide, page 10; Nutanix Certified Professional - Multicloud Automation (NCP-MCA), section 3; Nutanix Calm User Guide, page 93.
