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

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.)



Answer : C, D

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


Question 3

An administrator needs to ensure that Snapshot copies of database files across multiple FCP LUNs are taken at the same point in time.

Which two configurations enable the administrator to achieve this? (Choose two.)



Answer : C, D

To ensure that Snapshot copies of database files across multiple FCP LUNs are taken at the same point in time, the following configurations can be used:

Create a consistency group that uses FlexVol volumes: This setup ensures that snapshots of all volumes in the consistency group are taken simultaneously.

Create each LUN within the same FlexGroup volume: This configuration allows for a unified snapshot across multiple LUNs within the FlexGroup, ensuring data consistency.

Question 4

An SVM is created for FCP traffic. LUNs must be created to share with ESXi hosts for datastores. Which two items must be configured after the LUN is created, for this to happen? (Choose two.)



Answer : A, D

For configuring LUNs to share with ESXi hosts for datastores in an SVM created for FCP traffic, the following steps are necessary after creating the LUN:

Create an igroup with the ESXi hosts' WWPNs: This step involves defining an initiator group that includes the WWPNs of the ESXi hosts that need access to the LUN.

Map the LUNs to the igroup: This step assigns the LUN to the created igroup, allowing the ESXi hosts to access the LUN.

NetApp Documentation on LUN and igroup Configuration


Question 5

A customer Is setting up a four-node NetApp AFF cluster for use with NVMe/TCP and wants to use automatic host discovery.

Which protocol is used for the discovery of controllers?



Answer : B

For automatic host discovery in a four-node NetApp AFF cluster using NVMe/TCP, the protocol used is mDNS (Multicast DNS). mDNS allows for the discovery of controllers and other networked devices without the need for a centralized DNS server, simplifying the setup process in environments that support NVMe over TCP.

Question 6

A storage administrator recently implemented ISCSI SAN in a customer environment. Which two actions should be done to ensure the best performance? (Choose two.)



Answer : A, D

To ensure the best performance in an iSCSI SAN implementation:

Connect host and storage ports to the same switches: This minimizes latency and maximizes the efficiency of data paths by ensuring direct connections within the same network segment.

Configure Jumbo frames in the entire data path: Setting a larger Maximum Transmission Unit (MTU) size reduces the overhead for processing each packet, thus improving overall network performance. Ensuring Jumbo frames are configured end-to-end in the data path is crucial for optimal performance.

Question 7

A LUN Is displaying 90% used space in the NetApp ONTAP CLI, but a Windows Server shows only 10% used space.

What is the first step to take to address this issue?



Answer : D

When a LUN shows 90% used space in the NetApp ONTAP CLI but a Windows Server shows only 10% used space, the discrepancy is often due to how space allocation is handled between the two systems. Enabling space allocation ensures that the ONTAP system accurately reflects the actual space usage as reported by the host system, in this case, the Windows Server. This adjustment allows ONTAP to reclaim and manage space more effectively, aligning the reported usage between the ONTAP system and the host.
