D.
Create a new virtual private gateway dedicated to FSx for ONTAP data traffic
Suggested answer: B

Explanation:

When an administrator is unable to mount the file system from FSx for ONTAP to cloud instances within the same Virtual Private Cloud (VPC), the issue often lies with the network security settings. Specifically, verifying and adjusting the inbound and outbound rules of the security group associated with the VPC can resolve the issue. Here's the recommended approach:

Check Security Group Settings: Examine the security group rules associated with the cloud instances and the FSx for ONTAP system. Ensure that the rules allow NFS (or SMB/CIFS, depending on the protocol used) traffic between the instances and the FSx for ONTAP.

Adjust Rules as Necessary: If the current settings do not permit the required network traffic, modify the security group rules to allow the appropriate ports and protocols (e.g., TCP/UDP for NFS on port 2049).

Test Connectivity: After updating the security group settings, attempt to mount the file system again to confirm that the issue has been resolved.

For additional troubleshooting tips and configuration guidance, AWS documentation provides detailed instructions on setting up and managing security groups: AWS Security Groups Guide.
