At ValidExamDumps, we consistently monitor updates to the NetApp NS0-521 exam questions by NetApp. Whenever our team identifies changes in the exam questions,exam objectives, exam focus areas or in exam requirements, We immediately update our exam questions for both PDF and online practice exams. This commitment ensures our customers always have access to the most current and accurate questions. By preparing with these actual questions, our customers can successfully pass the NetApp Implementation Engineer - SAN ONTAP Exam exam on their first attempt without needing additional materials or study guides.
Other certification materials providers often include outdated or removed questions by NetApp in their NetApp NS0-521 exam. These outdated questions lead to customers failing their NetApp Implementation Engineer - SAN ONTAP Exam exam. In contrast, we ensure our questions bank includes only precise and up-to-date questions, guaranteeing their presence in your actual exam. Our main priority is your success in the NetApp NS0-521 exam, not profiting from selling obsolete exam questions in PDF or Online Practice Test.
After deleting a LUN, an administrator notices that the space does not show as available. What needs to be done to reclaim the space?
After deleting a LUN, if the space does not show as available, performing space reclamation is necessary. Space reclamation involves identifying and reclaiming unused space on the storage system, making it available for new data. This process ensures that the deleted LUN's space is properly freed up and reflected in the available storage capacity.

Which two NetApp features provide synchronous data replication between two sites for SAN workloads with automatic failover in case of a site disaster? (Choose two.)
For synchronous data replication between two sites with automatic failover in case of a site disaster for SAN workloads, the two NetApp features that provide these capabilities are SnapMirror Synchronous and MetroCluster IP.
SnapMirror Synchronous: This feature provides volume-granular, synchronous replication with zero RPO (Recovery Point Objective), ensuring that data is mirrored in real-time to a secondary site. This setup supports automatic failover, maintaining data availability even during site failures
MetroCluster IP: This solution provides synchronous replication and combines high availability and disaster recovery capabilities. MetroCluster IP uses IP networking to extend the distance over which replication can occur and supports automatic failover and failback, making it suitable for critical SAN workloads
An administrator configured an SVM with LUNs with two WWPNs per node. The administrator accidentally created a WWPN on node1 that needs to move to node2. The SAN hosts use ALUA.
Based on this requirement, what must be taken offline to correct the situation?
To move a WWPN from node1 to node2 in a NetApp ONTAP SAN environment where ALUA is used, you must take the Logical Interface (LIF) offline. Modifying LIFs involves changing their assignment between nodes, which requires them to be temporarily offline. This ensures that the path states are correctly updated without causing disruption to the SAN hosts.

NetApp Community on Moving LIFs
NetApp Documentation on SAN LIFs
A storage administrator wants to increase security and optimize performance in a recently implemented SAN deployment.
What should the storage administrator configure to ensure initiator restriction to certain LIFs?
To increase security and optimize performance in a SAN deployment, configuring an access list is essential. Access lists restrict initiator access to specific LIFs, ensuring that only authorized hosts can connect to the storage system. This helps in enhancing security by preventing unauthorized access and optimizes performance by controlling and managing the paths used for storage access.

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?
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.
