Netapp Updated NS0-522 Exam Questions and Answers by eyad

In a traditional FAS SAN configuration, ONTAP uses ALUA to distinguish optimized paths from non-optimized paths. Active/Optimized paths are serviced by the controller associated with the aggregate and LUN being accessed. These paths provide the preferred I/O route because data does not need to be forwarded through another controller. Paths through the HA partner remain available but are normally Active/Non-Optimized and are used when optimized paths become unavailable. NetApp host configuration guidance explicitly describes AFF and FAS systems as having higher-priority Active/Optimized paths serviced by the controller where the aggregate resides and lower-priority non-optimized paths served through another controller. Round-robin is a host multipathing policy and does not define ALUA path state. Relevant topics include ALUA, Active/Optimized paths, Active/Non-Optimized paths, FAS multipathing, and HA architecture.

In a multitenant environment where a user needs access only to perform replication within a specific SVM to another cluster, the default role vsadmin-backup is appropriate. This role provides the necessary permissions to manage backup and replication tasks without granting broader administrative rights.

To ensure that all network traffic is encrypted for iSCSI on an SVM, configuring IPsec is required. IPsec (Internet Protocol Security) provides end-to-end encryption for IP traffic, ensuring that data transmitted over the network is secure.

In NetApp ONTAP 9.14.1 software, the maximum size for a LUN is 128TiB. This limit ensures that large datasets can be stored and managed efficiently within a single LUN, catering to the needs of high-capacity SAN environments
