Nutanix NCP-MCA Dumps

To update the running configuration for a multi-VM application in AWS using the Manage tab for the application in Calm, the administrator needs to provide the provider information for the AWS account. This includes the access key, secret key, region, and VPC ID. If the provider information is missing, the administrator will not be able to perform any actions on theapplication from Calm. References: Nutanix Certified Professional - Multicloud Automation (NCP-MCA) Exam Blueprint Guide, page 16, section 4.1.1. 

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.

 The Send Alert to Webhook action allows the administrator to send an HTTP request to a specified URL, which can be used to trigger a PagerDuty incident via its REST API1. This action requires the least number of configurations compared to the other options, as it only needs the webhook URL, the HTTP method, and the payload. The other optionswould require additional steps, such as creating a custom action, configuring the IP address, or using the Nutanix v3 API, which is not designed for integrating with third-party services.
