NEW QUESTION # 52
What two pieces of information can an administrator obtain from Plays? (Choose two.)
- A. Execution result status
- B. Host where the action runs
- C. Start time and end time of each action
- D. CVM IP where the alert was triggered
Answer: A,B
Explanation:
Plays are event-driven automation workflows that can be triggered by alerts, schedules, or manual actions.
They consist of one or more actions that run on specified hosts or clusters. An administrator can obtain the following information from Plays:
* Host where the action runs: Each action in a Play can be configured to run on a specific host or cluster, or on the host or cluster where the alert was triggered. The administrator can view the host or cluster name for each action in the Play details page.
* Execution result status: Each action in a Play has an execution result status that indicates whether the action was successful, failed, skipped, or cancelled. The administrator can view the status for each action in the Play details page, as well as the overall status of the Play.
The other options are incorrect because:
* Start time and end time of each action: Plays do not show the start time and end time of each action, only the duration of the action. The administrator can view the duration for each action in the Play details page, as well as the overall duration of the Play.
* CVM IP where the alert was triggered: Plays do not show the CVM IP where the alert was triggered, only the host or cluster name where the alert was triggered. The administrator can view the host or cluster name for the alert in the Play details page.

NEW QUESTION # 70
Refer to the exhibit.
Calm encountered the error shown in the exhibit when importing a script that maps a network drive.
Upon further investigation, the Calm administrator was unable to run the script manually on a VM and discovered that elevated permissions were needed.
Which command should the administrator add to the script?
- A. Enable-WSManCredSSP -Role Server -Force
- B. Enable-WSManCredSSP -Role Server
- C. Disable-WSManCredSSP -Role Server -Force
- D. Enable-WSManCredSSP -Role Client
Answer: D
Explanation:
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.

These are the published and versioned Blueprints. The other two options, library of executable tasks and store of all Blueprints created in Calm, are not features of the Calm Marketplace. References: Calm: Marketplace - Read the Docs and Calm: Marketplace - Read the Docs
NEW QUESTION # 72
An administrator has a Linux VM that does batch processing out of a queue. Currently, a technician connects to the VM console and runs a command on the VM to initiate or terminate the batch processing application, as there is no programmatic interface for the application.
The application is processor intensive, so it should only run outside of business hours. The VM has the ability to send REST API calls to Prism.
How should the administrator configure a Playbook to satisfy the needs of this process with minimal external interaction?
- A. Manual Trigger > Power On > VM SSH > Wait for Some Time > Power Off VM
- B. Webhook Trigger > REST API > Wait for Some Time > REST API
- C. Time Trigger > VM SSH > Wait for Some Time > VM SSH
- D. Manual Trigger > VM SSH > Wait for Some Time > VM SSH
Answer: C
Explanation:
A Playbook is a collection of tasks that can be executed based on a trigger, such as a time, a webhook, or a manual action. A Playbook can be used to automate workflows across different systems and services, such as Nutanix Prism, VMs, hosts, and external APIs. A Playbook can also use variables, conditions, and loops to customize the execution logic and data.
In this scenario, the administrator wants to automate the batch processing application on the Linux VM, which can only be controlled by a command on the VM console. The application should run only outside of business hours, and the VM should send REST API calls to Prism to report its status.
The best way to configure a Playbook for this process is to use a Time Trigger, which allows the administrator to specify a schedule for the Playbook execution, such as daily, weekly, or monthly. The Time Trigger can also be configured to run only on certain days or hours, such as weekdays or nights. This way, the administrator can ensure that the Playbook runs only outside of business hours, without requiring any manual intervention.
The Playbook should then have two VM SSH tasks, one to initiate the batch processing application, and one to terminate it. A VM SSH task is a task that executes a command or script on a target VM using SSH. A VM SSH task can be used to control applications or services that do not have a programmatic interface, such as the batch processing application in this scenario. The VM SSH task can also use variables to pass data to or from the command or script, such as the VM name, IP address, or output.
The Playbook should also have a Wait for Some Time task, which is a task that pauses the Playbook execution for a specified duration or until a condition is met. A Wait for Some Time task can be used to ensure that the batch processing application has enough time to complete its work, or to wait for a certain event or state to occur, such as a file creation, a service status, or a VM power state.
The Playbook should also have two REST API tasks, one before and one after the Wait for Some Time task. A REST API task is a task that executes an HTTP request to a specified URL, with optional headers, body, and authentication. A REST API task can be used to interact with external systems or services that expose an API, such as Nutanix Prism inthis scenario. The REST API task can also use variables to pass data to or from the HTTP request, such as the VM name, IP address, or response.
The REST API tasks should be configured to send the VM status to Prism, such as the start and end time of the batch processing, the CPU and memory usage, or the output of the application. This way, the administrator can monitor and manage the VM and the application from Prism, without having to connect to the VM console.
The Playbook configuration should look something like this:
* Time Trigger: Set the schedule to run daily, only on weekdays, and only at night (e.g., 10 PM to 6 AM).
* VM SSH: Set the target VM to the Linux VM, and set the command or script to initiate the batch processing application (e.g., ./batch.sh start).
* REST API: Set the URL to the Prism API endpoint, and set the HTTP method, headers, body, and authentication as required. Use variables to pass the VM name, IP address, and start time of the batch processing to the HTTP request (e.g., {"vm_name": "{{vm_name}}", "vm_ip": "{{vm_ip}}",
"start_time": "{{start_time}}"}).
* Wait for Some Time: Set the duration to the expected time for the batch processing to finish, or set a condition to wait until a certain event or state occurs (e.g., wait until file /tmp/batch.done exists).
* REST API: Set the URL to the Prism API endpoint, and set the HTTP method, headers, body, and authentication as required. Use variables to pass the VM name, IP address, end time, and output of the batch processing to the HTTP request (e.g., {"vm_name": "{{vm_name}}", "vm_ip": "{{vm_ip}}",
"end_time": "{{end_time}}", "output": "{{output}}"}).
* VM SSH: Set the target VM to the Linux VM, and set the command or script to terminate the batch processing application (e.g., ./batch.sh stop).
