NEW QUESTION # 11
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?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: A
Explanation:
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 supportmultiple SAN and NAS protocols simultaneously, enabling efficient and consolidated management of storage resources.

NEW QUESTION # 12
What connectivity Is required between NetApp ONTAP clusters in order to configure SnapMirror active sync across two data centers for FC?
- A. Dedicated IP switches and ISL
- B. Shared FC switches
- C. Cluster peering
- D. Cedicated FC switches and ISL
Answer: C
Explanation:
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.

- B. SVM
- C. LIF
- D. LUN
Answer: C
NEW QUESTION # 14
A NetApp AFF node in a four-node cluster has a single FC port on one node, which Is used for legacy tape backup. Tape is no longer needed, and the port is disconnected and modified for reuse in the FCP SAN.
Based on this change, which command will verify that the port is usable?
- A. vserver fcp initiator show
- B. syszem node hardware unified-connect show
- C. networkinterface show
- D. lun persistent-reservationshow
Answer: B
Explanation:
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.

On a two-node NetApp AFF ASA cluster, what is the recommended minimum number of paths for a SAN environment from the client host perspective?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: D
Explanation:
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.

NEW QUESTION # 16
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?
- A. Active/Nonoptimized
- B. Active/Optimized
- C. Unavailable
- D. Offline
Answer: A
Explanation:
In the scenario where a storage failover is performed on Node 1 in an HA pair, the path marked in the exhibit would becomeActive/Nonoptimized. After the failover, the LIFs from Node 1 that were activeand optimized will switch to Node 2. Paths that were previously optimized will become nonoptimized because they are now served through the partner node.

NEW QUESTION # 17
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?
- A. CHAP authentication
- B. igroup creation
- C. LUN mapping
- D. LIF failover
Answer: D
Explanation:
In NetApp ONTAP 9.13.1, one of the automatic features that can be used with iSCSI isLIF 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
NEW QUESTION # 18
An administrator has a NetApp AFF cluster with two SVMs serving LUNs. SnapMirror active sync is configured, and a disaster recovery test is planned over the weekend.
Which NetApp ONTAP command will show the status of this test?
- A. snapnirror config-replication status show
- B. network interface failover-groups show
- C. storage failover hwassist show
- D. snapmirror failover show
Answer: D
Explanation:
To check the status of a SnapMirror active sync disaster recovery test on a NetApp ONTAP cluster, you would use the command snapmirror failover show. This command provides the necessary details about the failover status, helping administrators verify if the disaster recovery test is proceeding as expected. It displays the status of the failover groups and their readiness, which is essential for confirming the effectiveness of the disaster recovery setup.

NEW QUESTION # 19
During maintenance of A NetApp AFF ONTAP cluster, which two steps are needed to move the SAN UFs to new nodes that are members of a portset? (Choose two.)
- A. Take the SAN LIF offline.
- B. Disable the SLM feature for the node that hosts the LIF.
- C. Remove the LIF from the portset.
- D. Disable the zoning of the LIF WWPN.
Answer: A,C
Explanation:
To move SAN LIFs to new nodes that are members of a portset during maintenance of a NetApp AFF ONTAP cluster, you should take the following steps:
* Remove the LIF from the portset: This ensures that the LIF is no longer associated with the current node, preparing it for the move to the new node.
* Take the SAN LIF offline: This step is necessary to make configuration changes without causing disruption to the SAN hosts. Once offline, the LIF can be moved to the new node and reconfigured as needed.
These actions help maintain the integrity and performance of the SAN environment during the migration of LIFs.

NEW QUESTION # 20
Which two steps must be taken first to restore a LUN from a SnapMirror Synchronous destination? (Choose two.)
- A. Resync the relationship.
- B. Delete the relationship.
- C. Release the relationship.
- D. Initialize the relationship.
Answer: B,C
Explanation:
To restore a LUN from a SnapMirror Synchronous destination, the following steps must be taken:
* Release the relationship: This step is necessary to break the SnapMirror relationship, allowing the LUN to be restored independently.
* Delete the relationship: After releasing the relationship, deleting it ensures that there are no residual dependencies or configurations that might interfere with the restore process.
For more information, refer to:
* NetApp Documentation on SnapMirror Synchronous (NetApp) (NetApp).

NEW QUESTION # 22
What configuration must be applied for NVMe/FC?
- A. Create multiple initiator zones and multiple target zones.
- B. Configure igroup and IQN mapping.
- C. Enable NPIV on all fabric switches.
- D. Enable NPV on all fabric switches.
Answer: C
Explanation:
When configuring NVMe/FC (NVMe over Fibre Channel), it is necessary to enable N_Port ID Virtualization (NPIV) on all fabric switches. NPIV allows multiple Fibre Channel initiators to share a single physical Fibre Channel port, which is crucial for NVMe/FC environments where efficient utilization of available ports is needed.
NPIV support enables the creation of virtual ports, which can significantly optimize the configuration and management of Fibre Channel fabrics, thus supporting NVMe/FC operations.

NEW QUESTION # 24
An administrator creates a new volume and a LUN for an SAN-connected application that uses snapshots. The application has fast-growing data that is constantly being populated and deleted afterwards.
Which option can be set to manage the space automatically?
- A. Enable automatic resizing on the volume.
- B. Disable volume snapshot autodelete.
- C. Enable space reservation on the LUN.
- D. Unmap the LUN.
Answer: A
Explanation:
To manage space automatically for a volume containing a LUN with fast-growing data, enabling automatic resizing on the volume is recommended.

NEW QUESTION # 29
A storage administrator recently implemented ISCSI SAN in a customer environment. Which two actions should be done to ensure the best performance? (Choose two.)
- A. Zone the host by using the host WWPNs.
- B. Connect host and storage ports to the same switches.
- C. Decrease the default queue depth on the host to eight.
- D. Configure Jumbo frames In the entire data path.
