NS0-162 Exam Dumps : NetApp Certified Data Administrator (ONTAP)

To cache on-premises ONTAP volumes into the cloud with Cloud Volumes ONTAP, you need to use the FlexCache feature, which creates a writable, persistent cache of a data volume that is consistent and coherent with its original data set and stored in a remote location. FlexCache supports both SMB and NFS protocols, which are the traditional file access protocols for Windows and UNIX/Linux systems respectively. You can control file access using UNIX-style permissions, NTFS-style permissions, or a mix of both. Clients can access the same files using both SMB and NFS protocols123.

• NVMe and iSCSI are not supported by FlexCache, as they are block protocols that run on standard Ethernet networks. FlexCache is a file-based solution that works with file protocols only12. References :- Client protocols | NetApp Documentation, Client protocols - NetApp, Cloud Volumes ONTAP for AWS: Storage for the Cloud Era.

 The problem is that the NFS export policy only allows access to the IP range of 192.168.10.11-12, which does not include HOST 3’s IP address of 192.168.10.13. Therefore, the ESXi host cannot mount the NFS datastore. To solve the problem, you need to add HOST 3’s IP address to the NFS export policy, or modify the IP range to include it. This will grant the ESXi host the permission to access the NFS datastore. References :- ONTAP 9 Network Management Guide, ONTAP 9 NFS Reference, Troubleshooting NFS datastore connectivity issues (1003967)

When you perform an upgrade using ONTAP System Manager 9.8, you can use the automated nondisruptive update (ANDU) feature, which simplifies and streamlines the update process. The latest available images will appear in the ONTAP System Manager interface, and you can select the image you want to install. The update history is available within the ONTAP System Manager interface, and you can view the status and progress of the update. You do not need to manually upload the images to the cluster or download them from the NetApp Support site, as ONTAP System Manager will automatically download and upload the images as needed. References :- Automated nondisruptive ONTAP upgrade, How to Upgrade to ONTAP 9.8
