2V0-21.23 Question 11
Single answerA VMware administrator is tasked with configuring a shared storage solution to support a vSphere environment. The storage solution must allow for file-based access, integration with existing NAS devices, and support for VMware features such as vMotion and Storage vMotion. Which storage access protocol should the administrator select?
- A
NFS
- B
iSCSI
- C
Fibre Channel (FC)
- D
VMFS
Show answer and explanation
Correct answer: A
Explanation
The scenario specifies the need for a file-based storage access protocol that integrates with NAS devices and supports VMware features like vMotion and Storage vMotion. NFS is the correct choice as it is a file-based protocol supported by VMware for such use cases. iSCSI and Fibre Channel are block-based protocols and do not meet the file-based requirement, while VMFS is not a storage access protocol but a file system.
- A. Correct.
NFS (Network File System) is a file-based storage protocol that allows for shared storage access over a network. It is supported by VMware for use with features such as vMotion and Storage vMotion, making it suitable for this scenario.
- B. Incorrect.
iSCSI is a block-based storage protocol. While it supports VMware features, it does not provide file-based access, which is a requirement in this scenario.
- C. Incorrect.
Fibre Channel (FC) is another block-based storage protocol. Like iSCSI, it does not meet the file-based access requirement specified in this scenario.
- D. Incorrect.
VMFS (VMware Virtual Machine File System) is a clustered file system used on block storage devices. It is not a storage access protocol and does not integrate directly with NAS devices.
