2V0-21.23 Question 10
Single answerAn administrator is deploying a new VMware vSphere environment and needs to configure storage for the virtual machines. The requirement is to use a protocol that supports file-level storage, is easy to set up, and can leverage existing IP-based infrastructure. Which storage protocol should the administrator choose?
- A
iSCSI
- B
NFS
- C
Fibre Channel (FC)
- D
vSAN
Show answer and explanation
Correct answer: B
Explanation
The administrator's requirements specify file-level storage, simplicity, and compatibility with IP-based infrastructure. Among the listed options, NFS is the only protocol that meets all these criteria. It allows hosts to access shared storage over a network using standard IP protocols, making it ideal for this scenario.
- A. Incorrect.
iSCSI is a block-level storage protocol that uses IP-based infrastructure. While it is compatible with vSphere, it is not a file-level storage protocol and requires additional configuration for LUNs and targets.
- B. Correct.
NFS is a file-level storage protocol that is easy to set up and uses existing IP-based infrastructure, making it suitable for the requirements described.
- C. Incorrect.
Fibre Channel (FC) is a block-level storage protocol that requires dedicated hardware, such as Fibre Channel switches and HBAs, and does not meet the simplicity or IP-based infrastructure requirements.
- D. Incorrect.
vSAN is VMware's proprietary storage solution that aggregates local storage across ESXi hosts. While it simplifies storage management, it is not a traditional storage protocol like NFS, iSCSI, or Fibre Channel.
