2V0-21.23 Question 9
Single answerA VMware administrator is designing a storage solution for a new vSphere environment. The design requires shared storage for high availability, support for features like vSphere HA and vMotion, and the ability to scale capacity as needed. Which storage type would best meet these requirements?
- A
iSCSI
- B
NFS
- C
Direct-Attached Storage (DAS)
- D
vSAN
Show answer and explanation
Correct answer: D
Explanation
vSAN is the best choice for the described scenario because it is tightly integrated with vSphere, providing shared storage by aggregating local storage across hosts in a cluster. It supports high availability, vMotion, and scalability, making it an ideal solution for environments that require robust features and flexibility.
- A. Incorrect.
iSCSI is a good option for shared storage, but it might require additional setup and hardware considerations compared to vSAN. While it can support HA and vMotion, it does not offer the same integration and scalability as vSAN.
- B. Incorrect.
NFS is a file-based storage protocol that supports shared storage, HA, and vMotion, but it does not provide the same native integration and benefits as vSAN, such as storage policy-based management and scalability.
- C. Incorrect.
Direct-Attached Storage (DAS) is not suitable for shared storage in a vSphere environment because it is local to a single host and does not allow for HA or vMotion.
- D. Correct.
vSAN is a VMware-native storage solution that provides shared storage by pooling local storage across hosts in a cluster. It supports advanced features such as vSphere HA, vMotion, and storage policy-based management, making it the best choice for this scenario.
