2V0-21.23 Question 15
Single answerAn administrator is setting up storage for a VMware vSphere environment and needs to select a datastore type that supports features such as thin provisioning, snapshots, and improved performance in a vSphere cluster. The workload primarily involves virtual machines running business-critical applications. Which datastore type would be the most suitable for this use case?
- A
VMFS (Virtual Machine File System)
- B
NFS (Network File System)
- C
vSAN Datastore
- D
iSCSI LUN without VMFS
Show answer and explanation
Correct answer: A
Explanation
VMFS (Virtual Machine File System) is the most suitable datastore type for this scenario because it is specifically designed to optimize storage for VMware environments. It supports advanced features like thin provisioning, snapshots, and high performance, which are crucial for running business-critical virtual machines. While other storage types like NFS and vSAN have their use cases, VMFS is the optimal choice for this specific workload.
- A. Correct.
VMFS is a high-performance clustered filesystem designed specifically for VMware environments. It supports features like thin provisioning, snapshots, and clustering, making it suitable for business-critical workloads.
- B. Incorrect.
While NFS is a valid datastore type that supports features like snapshots, it may not provide the same level of performance and integration as VMFS for business-critical applications.
- C. Incorrect.
vSAN is a hyper-converged storage solution and could be a good option, but it requires additional configuration and resources, which may not be ideal for this use case.
- D. Incorrect.
An iSCSI LUN without VMFS lacks the advanced features and capabilities of VMFS, such as snapshots and thin provisioning, which are critical for this scenario.
