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Other certification materials providers often include outdated or removed questions by NetApp in their NetApp NS0-521 exam. These outdated questions lead to customers failing their NetApp Implementation Engineer - SAN ONTAP Exam exam.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.
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?
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.

A customer wants to configure an NVMe protocol-based NetApp ONTAP based storage system in a SAN environment.
What is used to configure the list of hosts?
When configuring an NVMe protocol-based NetApp ONTAP storage system in a SAN environment, a subsystem is used to configure the list of hosts. A subsystem in the NVMe context is an entity that groups NVMe namespaces (storage units) and presents them to the connected hosts. The hosts access these namespaces through the subsystem, allowing for efficient management and configuration of NVMe resources.
This configuration ensures that the appropriate hosts have access to the necessary namespaces for storage operations. This approach is critical in NVMe SAN environments to maintain high performance and manageability.

A customer wants to enable CHAP authentication on their iSCSI sessions.
Which command should be used to set up the appropriate security policies and passwords?
To enable CHAP (Challenge-Handshake Authentication Protocol) authentication on iSCSI sessions, the command vserver iscsi security create should be used. This command sets up the necessary security policies and passwords required for CHAP authentication, ensuring secure access to iSCSI targets.
For more details, refer to:
NetApp Documentation on iSCSI Configuration (NetApp).
What Is a recommended setting for using the NetApp ONTAP LUN fractional reserve?
The recommended setting for using the NetApp ONTAP LUN fractional reserve is to set the space guarantee to 'volume'. This setting ensures that the required space for overwrites in the volume is reserved, preventing potential write failures when snapshot copies are created. This setup helps in maintaining the performance and reliability of the storage system by ensuring there is always enough space allocated for the LUN.

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.
