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

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

 FabricPool is a feature of ONTAP that allows you to tier cold data from a local tier (aggregate) to a capacity tier (object storage) in the cloud or on-premises. ONTAP 9.8 supports four types of capacity tiers: AWS S3, Azure Blob, Google Cloud Storage, and ONTAP S3. StorageGRID is a NetApp product that provides on-premises S3 object storage. Therefore, both StorageGRID and ONTAP S3 are supported as capacity tiers for FabricPool aggregates in ONTAP 9.8. SWIFT Object Store and NFS Export are not supported as capacity tiers for FabricPool aggregates. References :- Considerations and requirements for using FabricPool, Storage Efficiencies, FabricPool with StorageGRID Recommendation Guide

 To increase access security in both NFS and iSCSI environments, you can use Kerberos and CHAP as authentication methods. Kerberos is a network authentication protocol that uses tickets to provide mutual authentication between clients and servers. CHAP is a challenge-response protocol that verifies the identity of a peer by using a shared secret. ONTAP supports Kerberos for NFS exports, which allows you to secure NFS traffic with encryption and integrity checking. ONTAP also supports CHAP for iSCSI LUN access, which prevents unauthorized access to iSCSI targets and initiators. References :- NFS security overview, iSCSI Security Configuration
