Question 87 - D-PSC-MN-01 discussion

To test connectivity between a Dell EMC PowerScale cluster and an NFS client, you should create an NFS export on the cluster and then mount it on the client. This verifies both network connectivity and proper NFS configuration.

Steps to Test NFS Connectivity:

Create an NFS Export on the Cluster:

Use the OneFS web administration interface or CLI to create an NFS export.

Specify the directory path and configure export permissions.

Configure Client Access:

Ensure the client's IP address is allowed in the export settings.

Adjust network configurations if necessary.

Mount the NFS Export on the NFS Client:

Use the mount command on the client:

mount -t nfs <cluster_ip>:/export_path /mount_point

Replace <cluster_ip>, /export_path, and /mount_point with appropriate values.

Verify Access:

Navigate to the mount point and perform read/write operations as permitted.

Why Other Options Are Incorrect:

Option A: Mapping a drive is applicable to SMB (Windows) clients, not NFS.

Option B: Pinging the DNS server tests name resolution, not NFS connectivity.

Option D: Accessing the cluster via a web browser tests HTTP connectivity.
