The best option to automate the installation of the local agent on all Linux VMs is to create an Endpoint that includes all Linux VMs and include the Endpoint in a Runbook that executes a shell script for agent installation. This way, the administrator can leverage the Calm Runbook feature, which allows orchestrating tasks across multiple VMs without the need of a blueprint or an application. The administrator can also filter the VMs by name, tag, or other criteria to select the target VMs for the Endpoint. The shell script can be added as a task in the Runbook and run on the selected Endpoint.

Option A is not correct because a Brownfield deployment is used to create an application from existing VMs and an existing blueprint. It is not suitable for automating tasks across multiple VMs without a blueprint. Moreover, a Brownfield deployment cannot attach to post-Calm created VMs, as they are already managed by Calm.

Option C is not correct because creating a new golden image and deploying all VMs again is a very time-consuming and disruptive process. It also requires the administrator to migrate the data and configuration of the existing VMs to the new ones. This option does not leverage the Calm automation capabilities and is not recommended. References: Nutanix Calm Runbooks & API Automation, Nutanix Support & Insights, Calm 3.0 is Here!, Nutanix Cloud Manager

Scaling VM replica settings allow you to specify the minimum, maximum, and default number of VMs that can be created from a blueprint service. The minimum and default values must be equal to or greater than the number of VMs needed at any time and at time of deployment, which is 2 in this case. The maximum value must be equal to or less than the project quota divided by the VM resources, which is 100/12 = 8 for vCPUs and 300/24 = 12 for memory. The lowest of these two values is the limit for the maximum value, which is 8. Therefore, the only option that meets all the requirements is B. MIN: 2, MAX: 7, Default: 2.

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]

Substrates are the components of a blueprint that define the cloud resources and configurations for deploying VMs or applications. Substrates can be associated with different cloud accounts, such as AWS, Azure, GCP, or Nutanix, to enable multicloud deployments. By using substrates, an administrator can create a blueprint that can deploy VMs to multiple clouds, depending on the availability, cost, or performance requirements.
