An administrator is providing users with access to the company's LOB applications through a VDI solution. The administrator received information that the company are going to hire 200 new employees who will be using these applications.

The environment is monitored by a third-party tool that notifies the administrator when the VDI solution is about to run out of capacity. This gives the administrator time to create additional resources and add them to the VDI solution.

What should the administrator use when creating a playbook to automate this?

A trigger based on a REST API

Answers
D.
A trigger based on an alert
Suggested answer: C

Explanation:

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.
