NCP-MCA: Nutanix Certified Professional - Multicloud Automation

According to the Nutanix Multicloud Automation Administration (NMCAA) course1, one of the prerequisites for using X-Play to automate tasks on VMs is to have SSH enabled and configured on the target VMs. This allows X-Play to connect to the VMs and execute commands or scripts remotely. If the SSH service is not running on the VMs, then X-Play will fail to connect and perform the actions, resulting in the error message shown in the exhibit. The other options are not likely to cause this error, as they are either unrelated to X-Play (A and B) or not required for X-Play to work .Reference:Nutanix Multicloud Automation Administration (NMCAA) course

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 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.Reference:Nutanix Certified Professional - Multicloud Automation (NCP-MCA) Exam Blueprint Guide, page 11; Nutanix Calm User Guide, section 3.1.

To automate the creation of a new user in GitLab for every new development environment, the administrator should perform the following tasks within a Calm blueprint:

Create an HTTP pre-create task to create the user in GitLab via REST API. This task will send an HTTP request to the GitLab server with the user information and credentials, and receive a response with the user ID and status. The administrator can use the response to verify the user creation and store the user ID as a variable for later use.

Create runtime-editable variables for user and password in the blueprint. These variables will allow the administrator to specify the user name and password for the new GitLab user at the time of launching the blueprint. The variables can be passed as parameters to the HTTP pre-create task and used in the REST API call.

The other two options are not correct because:

Adding a task within the service to ask for user and password at runtime is redundant and unnecessary, as the runtime-editable variables can already provide this functionality.

Creating a task script to login with ssh to GitLab and create a random user and password is not a good practice, as it exposes the GitLab server to security risks and does not use the REST API that GitLab provides for user management.Reference:

Protection Domains are a Nutanix feature that allows you to replicate data across clusters or to a remote site. You can use Protection Domains to replicate images from one cluster to another, and then use them for workload automation.This is one of the methods documented in the Nutanix Solutions Portal for Citrix MCS on Nutanix AHV1.Alternatively, you can also use Prism Central to manage multiple clusters and use Protection Policies to replicate images across clusters2. However, this option is not listed in the question, so the best answer is A.Reference:

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.

The error message indicates that the script failed to authenticate to the remote server using CredSSP. CredSSP is a security mechanism that allows a client to delegate its credentials to a remote server for authentication. To use CredSSP, both the client and the server need to enable it and configure the role and the trusted hosts. The command Enable-WSManCredSSP -Role Client enables CredSSP on the client side and specifies the remote server as a trusted host. This command should be added to the script before invoking the Invoke-Command cmdlet that runs the script block on the remote server. The other commands are either irrelevant or incorrect for this scenario.Reference:Nutanix Calm: PowerShell Scripts - Read the DocsandEnable-WSManCredSSP (Microsoft.PowerShell.Management) - PowerShell | Microsoft Docs.
