Exam 3V0-21.25 Topic 1 Question 48 Discussion

Actual exam question for VMware's 3V0-21.25 exam
Question #: 48
Topic #: 1
An administrator has been tasked with creating a workflow in VCF Operations orchestrator. The workflow will be used to take a snapshot before planned maintenance work is carried out within the virtual machine, and then automatically remove the snapshot at the end of the maintenance window. The following information has been provided for the workflow:
. The workflow must allow a user to specify a virtual machine on which a snapshot should be taken.
. The workflow must take a snapshot of the virtual machine specified by the user.
. The workflow must name the snapshot based on the current date and time.
. The workflow must delete all snapshots on the virtual machine after a cooling off period of 5 days has elapsed.
. The workflow must stop running after the snapshot is created, a second workflow should automatically start when the 5 day cooling off period has elapsed.
The administrator creates a new workflow for this task and adds an input parameter to allow the user to specify the virtual machine.
Drag and drop the additional five steps the administrator should perform to continue configuring the workflow from the Possible Steps list on the left and place them into the Selected Steps list on the right in any order (Choose five.)

Suggested Answer:


Explanation:
* Add a Variable of type string to the workflow named currentDate for storing the current date and time value.
* Add a Workflow element to the schema and configure it to use the Create a Snapshot workflow provided by the orchestrator workflow library.
* Map the name input parameter to the currentDate variable to define the name of the snapshot.
* Add a Schedule workflow element to the schema and configure it to use the Remove all snapshots workflow.
* Configure the Scheduled workflow to run 5 days from the value of the currentDate variable.
In VMware Cloud Foundation (VCF) 9.0, the Operations orchestrator (vRO) is used to build complex, state-aware automation. To satisfy the requirement that the main workflow stops running while a second cleanup task triggers later, the administrator must use the Schedule workflow element rather than a "Waiting Timer". A waiting timer keeps the workflow "Active," consuming system resources for the duration of the wait (5 days), whereas a scheduled task is handed off to the orchestrator's database to be triggered independently.
The configuration begins by defining a currentDate variable of type string. This variable captures the execution timestamp, which is then mapped to the Create a Snapshot library workflow to provide the required dynamic naming. To handle the automated cleanup, the administrator adds a Schedule workflow element. Unlike a standard workflow call, the scheduler allows for a specific execution offset.
By configuring the Remove all snapshots workflow to run 5 days from the currentDate value, the administrator ensures the snapshot exists for exactly the maintenance and cooling-off period before being programmatically removed. This approach is robust against orchestrator service restarts and provides a clean, asynchronous method for managing the temporary infrastructure lifecycle in a VCF
9.0 environment.
