Question No : 1

A company wants to ensure that all developers are able to request new development environments on demand by using ServiceNow.
The administrator notices that even though developers create new environments, they rarely remove these environments when moving on to new assignments. Today, the administrator has gone into Prism Central to check when the VM was created, in order to reach out to the developer and ask if it can be deleted. The administrator has accidentally deleted the wrong VM in the past.
Which two methods can the administrator use to automate this task to avoid deleting the incorrect VMs? (Choose two.)

A.Create a playbook REST API action to delete the VM from a ServiceNow approval flow.
B.Create a playbook webhook action to delete the VM from a ServiceNow approval flow.
C.Create a playbook webhook trigger to delete the VM from a ServiceNow approval flow.
D.Create a playbook REST API trigger to delete the VM from a ServiceNow approval flow.

정답:
Explanation:
A playbook REST API action allows the administrator to send an HTTP request to a specified endpoint, such as the Prism Central API, to perform an operation, such as deleting a VM. A playbook webhook action allows the administrator to send a payload to a specified URL, such as a ServiceNow webhook, to trigger an event, such as an approval flow. Both of these actions can be used to automate the deletion of VMs from a ServiceNow approval flow, where the developers can request and confirm the removal of their environments. A playbook webhook trigger and a playbook REST API trigger are not valid options, as they are used to initiate a playbook based on an external event, not to perform an action within a playbook.

A blueprint service needs to use scaling. The requirements are:
Windows 2019 VM (12 vCPU, 24 GB memory, 500 GB volume)
Minimum VMs needed at any time and at time of deployment is 2 VMs
VMs should not exceed the project quota of 100 vCPUs or 300 GB of memory
There are no other services in use within the project
Which scaling VM replica settings meet all requirements?

A.MIN: 2, MAX: 11, Default: 2
B.MIN: 2, MAX: 7, Default: 2
C.MIN: 2, MAX: 10, Default: 1
D.MIN: 2, MAX: 8, Default: 1

정답:
Explanation:
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.

Question No : 3

An administrator has built a Playbook to run a Powershell script in a VM when a specific alert is generated. Several days later, the alert is generated, but the script does not execute and there are no Plays recorded for the Playbook.
What is causing this issue?

A.The Playbook was never enabled.
B.The version of Playbooks is not correct for the version of Prism Central.
C.The script executed, but closed with an error code.
D.The path to the script was not correct.

정답:
Explanation:
A Playbook is a set of actions that are triggered by an event or a schedule. To run a Playbook, it must be enabled first. If a Playbook is not enabled, it will not respond to any events or schedules, and no Plays will be recorded for it. Therefore, the most likely cause of the issue is that the administrator forgot to enable the Playbook after building it.

Question No : 4

An administrator at a busy software development company is looking to roll out Calm for automation and estimates they will be creating 200 Projects, 500 Runbooks, 1500 Blueprints and automating the deployment of 7500 VMs for their development teams.
What size of Prism Central VM(s) is recommended to host the Calm environment?

A.3 nodes Large - 10vCPU and 52GB Memory per node.
B.1 node Small - 6vCPU and 30GB Memory per node.
C.3 nodes Small - 6vCPU and 30GB Memory per node.
D.1 node Large - 10vCPU and 52GB Memory per node.

정답:
Explanation:
According to the Nutanix Multicloud Automation Administration (NMCAA) course, the recommended Prism Central VM size depends on the number of VMs that are managed by Calm and the number of concurrent users. For a large-scale environment with more than 5000 VMs and more than 100 concurrent users, the recommended size is 3 nodes Large - 10vCPU and 52GB Memory per node1.
This size provides enough resources for the Prism Central cluster to handle the workload and performance requirements of Calm.

Question No : 5

An administrator has an existing set of VMs that were deployed before the company started using Calm. The administrator would like to now use Calm to manage those existing VMs.
What should the administrator do to manage the existing VMs?

A.Create a Greenfield Application, select the snapshots of the VMs to manage and redeploy the VMs from the latest snapshot.
B.Create a Brownfield Application, select the VMs that are needed for each deployment from the drop down list.
C.Create a Greenfield Application, select the VMs that are needed for each deployment from the drop down list.
D.Create a Brownfield Application, select the snapshots of the VMs to manage and redeploy the VMs from the latest snapshot.

정답:
Explanation:
A Brownfield Application is a type of application that allows you to import and manage existing VMs that were not deployed by Calm. You can use a Brownfield Application to perform actions such as start, stop, restart, delete, or execute scripts on the imported VMs. You can also add services, credentials, variables, and policies to the Brownfield Application blueprint. To create a Brownfield Application, you need to select a multi-VM blueprint and then choose the VMs that you want to include in the application from the drop down list. You can also filter the VMs by name, cluster, or power state.
A Greenfield Application is a type of application that allows you to deploy new VMs from scratch using Calm. You can use a Greenfield Application to provision and configure VMs on different cloud platforms, such as Nutanix AHV, VMware ESXi, AWS, Azure, or GCP. You can also add services, credentials, variables, and policies to the Greenfield Application blueprint. To create a Greenfield Application, you need to select a single-VM or a multi-VM blueprint and then specify the VM properties, such as name, image, flavor, network, storage, etc.

A.Nutanix provides a documented process to seed Github based scripts into the Calm Task Library.
B.Calm's public repository contains Nutanix-vetted custom scripts created and published by community members.
C.Nutanix publishes official vetted blueprints and tasks to Nutanix's public Github Calm repository.
D.Nutanix provides documented processes to seed scripts from any source repository.

정답:
Explanation:
Nutanix provides a documented process to seed Github based scripts into the Calm Task Library, which allows users to import and use custom tasks from the Nutanix public Github repository or any other Github repository. This process is described in the Nutanix Calm DSL User Guide and the Nutanix Calm DSL Tutorial.
Nutanix also publishes official vetted blueprints and tasks to Nutanix’s public Github Calm repository, which is located at https://github.com/nutanix/blueprints. These blueprints and tasks are created and maintained by Nutanix engineers and can be used as reference or templates for building Calm applications.
Some examples of these blueprints and tasks are:
Kubernetes Cluster: A blueprint that deploys a Kubernetes cluster on Nutanix AHV using Calm. MySQL HA: A blueprint that deploys a MySQL cluster with high availability on Nutanix AHV using Calm.
Windows Server: A blueprint that deploys a Windows Server 2019 VM on Nutanix AHV using Calm.
[Install Python]: A task that installs Python on a Linux VM using Calm.
Calm’s public repository does not contain Nutanix-vetted custom scripts created and published by community members. These scripts are hosted in a separate repository called [Automation], which is a centralized repo for community driven Nutanix automation. These scripts are not officially supported or endorsed by Nutanix and may not be compatible with the latest versions of Calm or Nutanix products.
Nutanix does not provide documented processes to seed scripts from any source repository. Users can only import scripts from Github repositories using the Calm Task Library.
Other source repositories are not supported by Calm.

Which two features does the Calm Marketplace provide? (Choose two.)

A.Published and versioned Blueprints
B.Library of executable tasks
C.Store of all Blueprints created in Calm
D.Set of pre-seeded application Blueprints

정답:
Explanation:
The Calm Marketplace acts as an application store, providing end users with a catalog of available applications. By default, Calm comes pre-seeded with validated Blueprints for multiple open source and enterprise applications. These are the set of pre-seeded application Blueprints. Additionally, Marketplace Manager acts as a staging area for publishing default and user-created Blueprints to your local Marketplace. 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.

Where would a Calm Developer find logging related to blueprint package failures?

A.In Calm select Application icon > select application name > Audit Tab
B.In Calm select Application icon > select application name > Services Tab
C.SSH to Prism Central > /home/calm/log/styx.log
D.In Prism Central go to Activities > Audits and get the audits filter by date

정답:
Explanation:
The styx.log file contains the logs related to blueprint packaging and deployment. It can be accessed by SSHing to Prism Central and navigating to the /home/calm/log directory. The other options are not relevant for blueprint package failures, as they show the application status, audit events, or service logs.

Question No : 10

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.Time Trigger > VM SSH > Wait for Some Time > VM SSH
C.Webhook Trigger > REST API > Wait for Some Time > REST API
D.Manual Trigger > VM SSH > Wait for Some Time > VM SSH

정답:
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 in this 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).

Question No : 11

Within a Calm blueprint, which two actions can an administrator apply to a Service under the Guest Customization section? (Choose two.)

A.Apply a Cloudinit Script
B.Apply a Sysprep file
C.Modify the base OS image
D.Choose UEFI or Legacy BIOS

정답:
Explanation:
Within a Calm blueprint, an administrator can apply two actions to a Service under the Guest Customization section: Apply a Cloudinit Script and Apply a Sysprep file. These actions allow the administrator to customize the configuration and behavior of the virtual machines that are provisioned from the blueprint. A Cloudinit Script is a set of commands or scripts that run on Linux-based virtual machines during the boot process. A Sysprep file is a configuration file that specifies the Windows settings and options for the virtual machines. These actions can be used to perform tasks such as setting the hostname, network configuration, user accounts, software installation, and more.

Question No : 14

A developer updated a blueprint to ensure that the IP address of the VM is reserved in IPAM as part of the deployment process. The developer noticed that when new VMs are created, they still get a DHCP IP address and not a reserved IP address.
What is the most likely reason for this behavior?

A.Developer created a pre-create task for reserving the IP address
B.Developer created a post-create task for reserving the IP address
C.Developer forgot to save the updated blueprint
D.Developer forgot to publish the updated blueprint

정답:
Explanation:
The most likely reason for this behavior is that the developer created a post-create task for reserving the IP address. A post-create task is executed after the VM is created and powered on, which means that the VM already obtained a DHCP IP address before the task is run. To reserve the IP address in IPAM as part of the deployment process, the developer should create a pre-create task instead. A pre-create task is executed before the VM is created and powered on, which allows the task to reserve the IP address in IPAM and assign it to the VM.

Question No : 15

Refer to the exhibit.

An administrator created the Playbook shown in the exhibit to allow for manual reduction of vCPU count on any selected VM within their environment. During a test run of the play on one of the VMs running in development, the administrator ran into an error that the Playbook cannot be completed against the selected VM.
Here are the details of the affected VM:
VM Name: VM2
vCPU: 4
RAM: 8 GB
OS: Windows 2016
Hypervisor: AHV
What caused this Playbook to fail?

A.This play cannot be executed against a VM on AH
B.The VM needs to be powered off before vCPU can be reduced.
C.Reduction of vCPU cannot be done on a VM with a running snapshot.
D.The play will cause the VM to go below the minimum vCP

정답:
Explanation:
The Playbook is designed to manually reduce the vCPU count on any selected VM within the environment. However, it failed during a test run on VM2 because there was a running snapshot of the VM. According to Nutanix Multicloud Automation (NCP-MCA) principles, you cannot reduce the vCPU count on a VM that has an active snapshot1. This is because the snapshot captures the state of the VM configuration and data, and reverting to a snapshot will restore both the guest OS and the virtual hardware2. Therefore, changing the vCPU count while a snapshot is running will cause inconsistency and error.
The other options are incorrect because:
A. The Playbook can be executed against a VM on AHV, as long as there is no snapshot running3.
B. The VM does not need to be powered off before vCPU can be reduced, as this can be done using hot-plug CPU feature4.
D. The play will not cause the VM to go below the minimum vCPU, as the minimum number of vCPUs is set to 1 in the Playbook, and the VM has 4 vCPUs initially.
