2V0-21.23 Question 18
Select 3A VMware administrator is configuring a new storage array that supports vStorage APIs for Array Integration (VAAI). The goal is to improve the efficiency and performance of virtual machine operations, such as cloning and Storage vMotion. Which of the following benefits are directly provided by enabling VAAI in this environment?
- A
Offloading certain storage-intensive operations to the storage array
- B
Reducing the load on the ESXi host CPU during storage operations
- C
Allowing the storage array to automatically resize VM disks when needed
- D
Improving the speed of virtual machine cloning and template deployment
- E
Enabling automatic tiering based on virtual machine usage patterns
Show answer and explanation
Correct answers: A, B, D
Explanation
VAAI is designed to improve the efficiency of storage operations by offloading certain tasks from the ESXi host to the storage array. This reduces the CPU and memory usage on the host and speeds up operations like cloning and template deployment. However, VAAI does not handle tasks like disk resizing or storage tiering, as these are outside its scope.
- A. Correct.
Correct: VAAI offloads specific storage operations, such as cloning and zeroing, to the storage array, reducing the workload on the ESXi host and improving performance.
- B. Correct.
Correct: By offloading tasks to the storage array, VAAI reduces the CPU and memory usage on the ESXi host during storage-related operations.
- C. Incorrect.
Incorrect: VAAI does not provide automatic disk resizing. This is typically managed through other VMware features or manual configuration.
- D. Correct.
Correct: VAAI accelerates operations like cloning and template deployment by allowing the storage array to handle these tasks more efficiently.
- E. Incorrect.
Incorrect: VAAI does not enable automatic tiering. Storage tiering is managed by the storage array itself or through other VMware features like Storage DRS.
