2V0-21.23 Question 388
Select 3A VMware administrator is tasked with configuring storage for a new vSphere cluster. The organization uses a mix of VMFS datastores and NFS datastores. During storage configuration, the administrator wants to ensure that multipathing is optimized to improve redundancy and performance for the VMFS datastores, while also ensuring proper configuration for the NFS datastores. Which actions should the administrator take to meet these requirements?
- A
Configure the Storage Array Type Plug-in (SATP) for the VMFS datastores to support specific multipathing policies.
- B
Enable NFS Multipathing by configuring multiple NICs on the NFS traffic port group.
- C
Set the path selection policy (PSP) to 'Round Robin' for the VMFS datastores to improve load balancing.
- D
Use the vSphere Web Client to enable iSCSI Port Binding for the NFS datastores.
- E
Ensure that all NFS datastores are mounted with the 'Read-Only' option to improve redundancy.
Show answer and explanation
Correct answers: A, B, C
Explanation
To optimize multipathing for VMFS datastores, the administrator must configure the appropriate SATP and set the PSP to 'Round Robin' for load balancing. For NFS datastores, enabling multipathing through multiple NIC configurations ensures redundancy and performance. The incorrect options involve misconfigurations or irrelevant features (e.g., iSCSI Port Binding or Read-Only NFS mounts), which do not contribute to the stated requirements.
- A. Correct.
This is correct because configuring the Storage Array Type Plug-in (SATP) allows the administrator to define appropriate multipathing policies for VMFS datastores, ensuring redundancy and optimized performance.
- B. Correct.
This is correct because enabling NFS Multipathing by configuring multiple NICs provides network redundancy and improves performance for NFS datastores.
- C. Correct.
This is correct because setting the PSP to 'Round Robin' for VMFS datastores helps distribute I/O load across multiple paths, optimizing performance.
- D. Incorrect.
This is incorrect because iSCSI Port Binding is used for iSCSI storage configurations, not for NFS datastores. NFS datastores do not rely on iSCSI Port Binding.
- E. Incorrect.
This is incorrect because mounting NFS datastores as 'Read-Only' does not improve redundancy. It restricts writes and is only used for specific use cases, such as backups or archival data.
