Test Script is a feature of Nutanix Cloud Manager (NCM) Self-Service that allows users to test or validate scripts before deployment. Test Script enables users to run scripts on a VM without creating a blueprint or a runbook. Users can select a VM, choose a script type, enter the script content, and execute the script. The output of the script is displayed in the Test Script window. Test Script can be used to troubleshoot errors, verify functionality, or preview the results of a script before using it in a blueprint or a runbook. References: Nutanix Certified Professional - Multicloud Automation (NCP-MCA) Exam Blueprint Guide, page 14, section 3.1. Nutanix Multicloud Automation Administration (NMCAA) course, module 3, lesson 4. Validate Your Nutanix Cloud Manager Self-Service Skills + Access Special Offer.

The best way to automate the scale-out of the application layer using a third-party tool is to create a Playbook with a webhook as a trigger and a REST API call as an action. A webhook is a mechanism that allows a third-party service to send a notification to a Calm server when a certain event occurs, such as a code commit or a build completion. A REST API call is a way to interact with the Calm server programmatically, such as launching a blueprint or scaling out a service. By creating a Playbook that combines these two elements, the administrator can enable the third-party tool to trigger the scale-out action on the Calm server with a single command. The other options are either not feasible, not efficient, or not relevant for this task. References: Nutanix Calm: Playbooks - Read the Docs and Nutanix Calm: REST API - Read the Docs.

Calm can be deployed as a VM on ESXi or AHV hypervisors and leverage calm functionality without the Nutanix infrastructure. Calm can also be enabled inside of Prism Central, which is a VM that can run on any Nutanix supported hypervisor, including ESXi and AHV. However, Calm cannot be enabled inside of Prism Element, which is the management interface for each Nutanix cluster. Calm also cannot be deployed as a VM on Hyper-V, as this is not a supported hypervisor for Calm. References: Nutanix Calm Configuration and Training, Calm on ESXi Deployment | Nutanix Community, Nutanix Support & Insights

The hercules.log file is the log file for the Calm service, which is responsible for managing the integration with various cloud providers, including Azure. The administrator can check this log file to troubleshoot any issues related to the Azure integration, such as authentication, configuration, or communication errors. The other log files are not relevant for the Azure integration. The sytx.log file is the log file for the Sytx service, which is responsible for managing the Calm UI and API. The durga.log file is the log file for the Durga service, which is responsible for managing the Calm Marketplace and blueprints. The arjun.log file is the log file for the Arjun service, which is responsible for managing the Calm runbooks and playbooks.

To make a custom variable type available for all deployments, the developer should publish the variable type to the Marketplace. By publishing it to the Marketplace, the variable type becomes accessible to all administrators and users across different projects, ensuring consistency and reusability.

To launch application deployments on any remote Prism Central (PC) from the PC hosting Calm Global, the administrator must create a Nutanix account for each remote PC on the local PC (the one hosting Calm Global) and add these accounts to the relevant project. This setup allows Calm to manage and orchestrate resources across multiple Prism Central instances.

 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.

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]

The administrator needs to add AWS as a provider in Calm. 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. To add a provider, the administrator needs to go to the Providers page in the Calm UI and click on the +Create Provider button. Then, the administrator needs to select the AWS provider type and enter the required information such as name, access key, secret key, and regions. References: Nutanix Certified Professional - Multicloud Automation (NCP-MCA) Exam Blueprint Guide, page 11; Nutanix Calm User Guide, section 3.1.

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. References: 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
