NS0-304 NetApp Certified Hybrid Cloud Administrator Professional Exam Questions and Answers

For Cloud Data Sense to scan an NFS volume effectively, it requires appropriate access permissions to the files and directories within the volume. Since the issue involves Cloud Data Sense not scanning a newly provisioned NFS volume, the most likely cause is insufficient read permissions. Here’s what to do:

• Verify and Modify NFS Export Policies:Check the NFS export policies associated with the volume to ensure that they allow read access for the user or service account running Cloud Data Sense. This permission is critical for the service to read the content of the files and perform its data classification and management functions.
• Adjust Permissions if Necessary:If the current permissions are restrictive, modify the export policy to grant at least read access to Cloud Data Sense. This might involve adjusting the export rule in the NetApp management interface.
• Restart Cloud Data Sense Scan:Once the permissions are correctly configured, initiate a new scan with Cloud Data Sense to verify that it can now access and scan the volume.

For further guidance on configuring NFS permissions for Cloud Data Sense, refer to the NetApp documentation on managing NFS exports and Cloud Data Sense configuration: NetApp Cloud Data Sense Documentation.

When configuring an iSCSI LUN for use on a Cloud Volumes ONTAP (CVO) HA instance in AWS, especially during failover testing for host access, the administrator must use a Floating IP address. Here’s why:

• Purpose of Floating IP:In an HA configuration, the Floating IP provides a consistent network address that remains accessible, even when the service fails over from one node to another. This ensures that any connections to the iSCSI LUN remain uninterrupted during node failures.
• Configuration and Testing:By using a Floating IP, the administrator ensures that the storage clients or hosts always connect to the active node, maintaining access to the iSCSI LUN even during the failover processes.
• High Availability Setup:During failover testing, the Floating IP facilitates the seamless transition of network services from one node to another without requiring configuration changes on the client side or re-establishing connectivity.

For more details on configuring Floating IPs in a NetApp CVO HA setup in AWS, you can refer to the NetApp documentation on HA configurations: NetApp High Availability Guide.

If an administrator has iSCSI LUNs on an AWS FSxN instance and is unable to mount these LUNs from a Linux host in the same AWS region due to the host being in a different Virtual Private Cloud (VPC), the solution is to configure VPC peering. Here’s the process:

• VPC Peering Setup:VPC peering allows two VPCs to communicate with each other as if they are in the same network. This enables the Linux host to connect to the AWS FSxN instance across different VPCs.
• Configuration Steps:To set up VPC peering, the administrator must create a peering connection between the two VPCs in the AWS Management Console, and then update the route tables in each VPC to allow traffic to and from each other.
• Mounting iSCSI LUNs:Once VPC peering is configured, the network route will be established, allowing the Linux host to successfully mount the iSCSI LUNs located on the FSxN instance.

For guidance on setting up VPC peering in AWS, consult the AWS documentation:AWS VPC Peering Guide.
