2V0-21.23 Question 19
Select 2A VMware administrator is configuring a vSphere environment with a storage array that supports VMware APIs for Storage Awareness (VASA). The administrator needs to ensure that the environment is optimized for storage performance and redundancy. Which two configurations should the administrator implement to achieve this? (Choose two.)
- A
Register the storage array with the vCenter Server using VASA Provider.
- B
Enable round-robin multipathing policy for the datastore.
- C
Disable VAAI (vSphere APIs for Array Integration) to avoid conflicts with VASA.
- D
Configure Storage Policies to leverage capabilities advertised by the VASA Provider.
- E
Manually create and assign paths to each LUN for improved control.
Show answer and explanation
Correct answers: A, D
Explanation
To optimize the vSphere environment with VASA, the administrator must register the storage array with the vCenter Server using the VASA Provider to enable communication and integration between the array and vSphere. Additionally, configuring Storage Policies allows the administrator to leverage the array's advertised capabilities, ensuring that storage is allocated and used according to the organization's requirements. These steps are essential for leveraging the full capabilities of VASA and improving storage performance and management.
- A. Correct.
Registering the storage array with the vCenter Server using the VASA Provider is necessary to take advantage of the storage array's advertised capabilities, such as data services and health monitoring.
- B. Incorrect.
Enabling the round-robin multipathing policy can optimize performance, but it is not specifically tied to VASA or required for this scenario. It is a general best practice for multipathing but not directly related to the question.
- C. Incorrect.
Disabling VAAI is not recommended, as VAAI complements VASA by improving storage performance through hardware acceleration. Disabling it would reduce storage efficiency.
- D. Correct.
Configuring Storage Policies based on the capabilities advertised by the VASA Provider ensures that storage is allocated according to performance, availability, or other specific requirements. This is a key benefit of using VASA.
- E. Incorrect.
Manually creating and assigning paths to each LUN is not required or recommended, as VMware's native multipathing mechanisms handle path management effectively and efficiently.
