NetApp Implementation Engineer - SAN ONTAP NS0-521 Exam Questions
Question 1
An administrator runs the vserver nvme namespace convert-from-iun command on a NetApp ASA cluster to increase host performance.
What is modified by the convert command?
Answer : D
The vserver nvme namespace convert-from-lun command in a NetApp ASA cluster is used to convert a LUN to an NVMe namespace to increase host performance. This process involves modifying the metadata of the storage object to make it compatible with the NVMe protocol, allowing for faster access and reduced latency
Question 2
An administrator finishes an installation of a new NetApp ASA system at the customer site and creates a new LUN. The customer wants to restrict the access of the LUN to specific UFs.
Where would the administrator configure this?
Answer : B
To restrict access to a newly created LUN to specific hosts, the administrator should configure the igroup (initiator group). An igroup is used to control which initiators (hosts) are allowed to access specific LUNs. This ensures that only authorized hosts can access the storage, enhancing security and access control.
For more details, refer to:
NetApp Documentation on iGroups (NetApp).
Question 3
A four-node NetApp ONTAP SAN cluster has been deployed. After installation, the engineer wants to verify cabling.
Which NetApp tool should the engineer use?
Answer : B
To verify the cabling of a four-node NetApp ONTAP SAN cluster after installation, the recommended tool is Active IQ Config Advisor. This tool provides detailed checks for proper configuration, including cabling verification, and helps ensure that best practices are followed for optimal performance and reliability.

Question 4
A customer requires multiple SAN and NAS protocols on a NetApp AFF cluster. The cluster must concurrently serve a namespace over NVMe/FC, a LUN over FCP, a LUN over iSCSI, and an NFS export.
Based on these requirements, what is the minimum data SVM count that is required?
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.

Question 5
An administrator upgraded their NetApp ONTAP software from release 9.10.1 to 9.13.1 on a NetApp All SAN Array (ASA) cluster and is creating a new iSCSI SVM.
Which automatic feature can be used with iSCSI?
Answer : A
In NetApp ONTAP 9.13.1, one of the automatic features that can be used with iSCSI is LIF failover. This feature ensures that in the event of a network failure or a node issue, the Logical Interface (LIF) will automatically fail over to another available port, maintaining connectivity and minimizing disruption to iSCSI traffic.

NetApp ONTAP 9.13.1 Features
Question 6
Click the Exhibit button.
A customer is testing a newly installed NetApp AFF A400 all-flash HA storage system. An SVM for FCP with a LUN on Node 1 has been configured, and a server has been connected as shown in the exhibit. For testing, the engineer plans to do a storage failover of Node 1.
After the failover, what is the expected status of the marked path?
Answer : C
In the scenario where a storage failover is performed on Node 1 in an HA pair, the path marked in the exhibit would become Active/Nonoptimized. After the failover, the LIFs from Node 1 that were active and optimized will switch to Node 2. Paths that were previously optimized will become nonoptimized because they are now served through the partner node.

NetApp Documentation on ALUA
Question 7
What needs to be done to create a consistent Snapshot copy of a LUN without disruptions?
Answer : B
To create a consistent Snapshot copy of a LUN without disruptions, it is necessary to quiesce I/O to the LUN. This process involves pausing or temporarily stopping the input/output operations to ensure that the data is in a consistent state when the snapshot is taken. This method is crucial for maintaining data integrity and consistency in the snapshot.
