NetApp NS0-521 Implementation Engineer - SAN ONTAP Exam Practice Test

Answer : C

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

Answer : B

To verify if jumbo frames have been configured correctly for an iSCSI workload, the command ping -lif <LIF> -vserver <SVM> -destination <IP> -disallow-fragmentation true -packet-size 9000 should be used. This command tests the network path with the jumbo frame size (9000 bytes) and ensures that the packets are not fragmented, confirming that jumbo frames are supported end-to-end.

Answer : C

To concurrently serve a namespace over NVMe/FC, a LUN over FCP, a LUN over iSCSI, and an NFS export, only one data SVM (Storage Virtual Machine) is required. NetApp ONTAP allows a single SVM to support multiple SAN and NAS protocols simultaneously, enabling efficient and consolidated management of storage resources.

Answer : C

To verify that a modified FC port is usable after it has been repurposed from tape backup to FCP SAN, the command system node hardware unified-connect show should be used. This command checks the status and configuration of the unified connect hardware, ensuring that the port is correctly set up for the new function in the SAN environment.

Answer : C

In a two-node NetApp AFF ASA cluster, the recommended minimum number of paths for a SAN environment from the client host perspective is 4. This configuration ensures high availability and load balancing, which are critical for maintaining performance and resilience in a SAN environment. Each host should have at least two paths to each controller to achieve this setup.

Answer : A

For a NetApp AFF All SAN Array (ASA) A800 MetroCluster IP configuration with 72 disks per site and Cisco N9K-C9336C-FX2 backend switches, the minimum number of rack units required on each site is 16 RU. This includes space for the controllers, disk shelves, and the necessary network switches. This configuration ensures that all components are properly accommodated and operational within the specified rack space.

Answer : C

To configure SnapMirror active sync across two data centers using FC (Fibre Channel), the required connectivity between NetApp ONTAP clusters is cluster peering. Cluster peering involves establishing a trust relationship between the clusters, allowing them to replicate data seamlessly. This setup ensures that data synchronization and disaster recovery processes are effective and reliable.
