Question 1
An administrator has Playbook that continues to fail with this error:
failed to execute action with error: Internal Error, Maximum Memory size limit reached.
What action are required to resolve the issue?
Answer : A
A Playbook action has a default memory limit of 256 MB, which can be increased up to 1024 MB in the advanced settings of the action. If the action requires more memory than the limit, it will fail with the error message ''Internal Error, Maximum Memory size limit reached''. To resolve this issue, the administrator can edit the action and increase the memory limit to a suitable value, depending on the complexity and requirements of the action.
Question 2
An administrator needs to create a Playbook to be notified when VMs are deleted.
Which X-Play Trigger would satisfy this task?
Question 3
An administrator is trying to deploy a VM from an image onto a newly-built cluster, but the image is unavailable. The administrator is able to deploy the image onto other clusters with no issue. Image placement policies have already been created within Prism Central.
Why is the image unavailable for deployment on the cluster?
Question 4
An administrator wants to create a blueprint for a development environment that uses an existing on-premise GitLab repository. Every new development environment requires a new user in the GitLab repo.
Which two tasks should the administrator perform within a Calm blueprint to automate this process? (Choose two.)
Answer : A, B
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:

Question 5
A developer Is building and testing a new Blueprint to deploy a Window Server VM on AHV. During one of the test runs, the application build fails.
The developer asks an administrator to investigate the failure. After careful review, the administrator finds this error message on a task that execute a Poweredshell script.
What is the cause of this error message?
Answer : B
The error message 'A specified logon session does not exist. It may already have been terminated' is often caused by the lack of CredSSP (Credential Security Support Provider) being enabled on the Windows Operating System. CredSSP is necessary for certain remote operations, including executing PowerShell scripts remotely.

Question 6
Refer to the exhibit.
A subset of Linux VMS is required to be gracefully shutdown each evening. A Playbook is created to shut down the targeted VMs, however, the error message shown in the error message when the Playbook is executed.
Data flow
Playbook execution terminated due to action failure.
Trigger
Manual
Action
Power of vm
Error message Failed to with Internal Error. VM power state task failed to complete. status: Error: INTERNAL_ERROR: Errorcode: 9
What is causing the error message?
Answer : D
The error message ''INTERNAL_ERROR: ErrorCode: 9'' typically indicates an issue with the SSH service on the VMs. In this context, where a playbook is being executed to shut down Linux VMs, it's essential that the SSH service is running to allow for remote management and execution of commands. If the SSH service isn't running, the playbook won't be able to execute commands on the VMs, leading to an internal error.
Question 7
When a developer launches the created Blueprint within the Blueprint Editor, the application gets deployed correctly. However, when the Blueprint is launched via Marketplace, it gets a check login error.
