VCP-CMA 2024 Question 201
Single answerAn administrator is configuring a storage profile in VMware vRealize Automation (vRA) to meet the following requirements:
- Ensure that virtual machines (VMs) are provisioned on datastores with sufficient free space.
- Prevent placement of VMs on datastores with known performance issues.
- Automatically apply policies based on storage capabilities.
Which configuration step should the administrator take to meet the requirements?
- A
Create and configure a tag-based storage profile linked to specific datastore tags.
- B
Enable the 'Storage I/O Control' feature on all datastores in the vCenter Server.
- C
Define a custom placement policy in vRealize Automation and associate it with the storage profile.
- D
Configure a storage profile that uses vSphere Storage DRS to manage datastore placement.
Show answer and explanation
Correct answer: A
Explanation
To meet the requirements of ensuring sufficient free space, avoiding performance issues, and applying policies automatically, tag-based storage profiles are the most appropriate solution. By tagging datastores with relevant attributes and linking them to storage profiles, vRealize Automation can intelligently deploy VMs to suitable datastores.
- A. Correct.
This is the correct answer because tag-based storage profiles allow the administrator to define policies based on datastore tags. These tags can indicate free space, performance characteristics, or other criteria, ensuring VMs are placed on appropriate datastores.
- B. Incorrect.
Enabling 'Storage I/O Control' manages storage performance but does not facilitate placement policies based on datastore attributes. It is not sufficient to meet the requirements described.
- C. Incorrect.
Custom placement policies in vRealize Automation are not directly associated with storage profiles. They are typically used for VM placement in clusters rather than specific datastore management.
- D. Incorrect.
While Storage DRS helps with load balancing and initial placement, it does not provide the granularity required to define specific datastore attributes such as performance or free space.
