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.

Categories are a way of organizing and managing resources in Nutanix Calm. Categories can be used to define access policies, filter resources, and group applications. By assigning new VMs to a category, the administrator can grant access to the OS Team based on their Active Directory Group membership. The OS Team can then use the web SSH console to access the Linux VMs from the Calm UI.

The administrator should modify the alert by adding the correct category and assign the category Environment:Development to development VMs. By doing this, they can filter out alerts for development VMs that are expected to have memory constrained alerts and focus on those that are critical, such as production VMs. This is based on the general practices in managing alerts in a multicloud environment, as well as the specific features and requirements of Nutanix Calm and Prism Central.Reference:

According to the Nutanix Calm Administration Guide1, the minimum system requirements for Prism Central are 32 GB of RAM and 8 vCPUs. If the production Prism Central has less than the minimum RAM, it may affect the performance of Calm and other services running on Prism Cen

Runtime variables are used to pass information between different components of a Blueprint, such as VMs, services, tasks, and replicas. They can be defined in the Blueprint YAML file or in the UI. By setting the mount_path as a runtime variable, the administrator can ensure that both database VMs use the same value for the mount_path during the deployment. This way, the backup files can be hosted on the same location for both VMs.Reference:

An HTTP task is a type of task that can be added to a blueprint or a runbook to perform REST API calls to external systems. An HTTP task can be used to reserve an IP address in the IPAM system before deploying a VM or an application, by sending a POST request with the required parameters and headers. The HTTP task can also capture the response from the IPAM system and store it as a variable for later use. This is the simplest and most efficient way to integrate with an IPAM system, as it does not require any additional configuration or scripting.

The error code 1314 indicates that the user does not have the required privilege to perform the requested operation. This means that the credentials provided in the Calm Blueprint are not valid or do not have enough permissions to run the script on the Windows machine. To fix this issue, the administrator should verify the credentials and ensure that they have the appropriate rights to execute the script, such as local administrator or domain administrator privileges.Reference:Nutanix Certified Professional - Multicloud Automation (NCP-MCA) Exam Blueprint Guide, page 15, section 3.3.Nutanix Multicloud Automation Administration (NMCAA) course, module 5, lesson 2.Nutanix NCP-MCA Certification Exam Sample Questions, question 25.

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.
