BC
Explanation:
For a successful deployment of a switchless HA pair with two NetApp DS224C shelves in an already populated rack, it is crucial to verify:
Rack units: Ensure that there are enough rack units available to accommodate the new shelves and any associated equipment. Proper planning of space in the rack is essential for a neat and functional setup.
Power connections: Verify that there are sufficient and appropriately rated power connections available. Ensuring proper power distribution and redundancy is critical for the reliability and uptime of the storage system.

A customer has a two-node NetApp AFF ASA cluster in an environment with a Cisco Fibre Channel SAN and Cisco UCS Servers. The customer wants to upgrade the UCS Server BIOS and the Cisco NX-OS system running on the switches.
Which NetApp resource should be consulted to check compatibility with the new versions?
- A . Interoperability Matrix Tool (IMT)
- B . BlueXP digital advisor
- C . Hardware Universe
- D . Active IQ Config Advisor
A
Explanation:
When planning to upgrade the UCS Server BIOS and Cisco NX-OS system running on the switches in a NetApp AFF ASA cluster environment, the Interoperability Matrix Tool (IMT) is the recommended resource to check compatibility with the new versions. The IMT provides detailed compatibility information for various hardware and software components, ensuring that the planned upgrades will not cause any interoperability issues.

An administrator has a NetApp AFF cluster supporting an application with twelve LUNs allocated across four volumes. There is a requirement to configure a Snapshot copy of all LUNs simultaneously as a single unit.
Which NetApp ONTAP command should be used to configure this requirement?
- A . lun igroup create
- B . network port ifgrp create
- C . volume conversion start
- D . vserver consistency-group create
D
Explanation:
To configure a Snapshot copy of all LUNs simultaneously as a single unit in an application with multiple LUNs spread across several volumes, the command vserver consistency-group create should be used. This command creates a consistency group that allows for coordinated snapshot creation across multiple volumes, ensuring that the snapshots are consistent with each other.

A customer has created an SVM for their SAN workloads. They now want to configure the SVM to use NVMe/FC.
Which two steps are needed to accomplish this task? (Choose two.)
- A . Add the FC protocol.
- B . Create the FC service.
- C . Create an NVMe/FC LIF.
- D . Create the NVMe service.
AC
Explanation:
To configure an SVM to use NVMe/FC, the following steps are necessary:
Add the FC protocol: This step involves enabling the Fibre Channel protocol on the SVM, which is required to support NVMe over Fibre Channel.
Create an NVMe/FC LIF: Logical Interfaces (LIFs) must be created to handle NVMe traffic over the Fibre Channel network. These LIFs enable the NVMe namespace access to the host systems.
These steps ensure that the SVM is correctly set up to use NVMe/FC, allowing for efficient and high-performance access to NVMe storage.

NetApp NVMe/FC Configuration
A storage engineer in SAN environment needs to Identify FC ports using the company-wide naming policy.
Which command will accomplish this task?
- A . vserver fcp wwpn-alias set
- B . network interface modify
- C . TCP portname set
- D . ucadmin modify
A
Explanation:
The vserver fcp wwpn-alias set command is used to set or modify the World Wide Port Name (WWPN) aliases for Fibre Channel (FC) ports in a NetApp ONTAP environment. This command allows you to apply a company-wide naming policy to FC ports, ensuring consistent and easily identifiable naming conventions across your storage infrastructure.
For further details, you can refer to:
NetApp Documentation on FC Management
NetApp Community Discussion on WWPN Aliases
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?
- A . LIF
- B . LUN
- C . SVM
- D . Volume
A
Explanation:
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.

A customer asks for help cloning one database LUN from a SnapMlrror destination volume for testing the data with a new application.
What command should the administrator use to clone the LUN?
- A . volume file clone create
- B . lun wove start
- C . volume clone create
- D . volume move start
C
Explanation:
To clone a LUN from a SnapMirror destination volume for testing purposes, the volume clone create command should be used. This command creates a FlexClone volume from the SnapMirror destination, making the LUN within it accessible for testing without disrupting the original volume.
For more details, refer to:
NetApp Documentation on Volume Clone Create
NetApp Community Discussion on LUN Cloning
An engineer Is implementing a data migration scenario for a customer who has multiple FC LUNs across multiple third-party SAN arrays. The engineer wants to use Foreign LUN Import (FLI) for the migration.
What is a requirement on the destination NetApp ONTAP cluster for FLI?
- A . A valid SnapMirror license
- B . At least one FC port in initiator mode
- C . A valid NetApp XCP license
- D . At least one FC port in target mode
D
Explanation:
When using Foreign LUN Import (FLI) for migrating LUNs from third-party SAN arrays to a NetApp ONTAP system, one of the requirements is to have at least one Fibre Channel (FC) port configured in target mode on the destination NetApp ONTAP cluster. This configuration is necessary to facilitate the migration process as the target mode port will accept and manage incoming data from the source SAN arrays.
For additional details, refer to:
NetApp Documentation on FLI
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 NPV on all fabric switches.
- D . Enable NPIV on all fabric switches.
D
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.

NetApp Community – NVMe/FC Configuration (NetApp Community).
NetApp Documentation – NVMe Overview (NetApp).
A customer Is setting up a two-node cluster to serve (SCSI LUNs.
How many interfaces should be created?
- A . One iSCSI LIF per node
- B . One ISCSI LIF per SVM
- C . Two iSCSI LIFs per node
- D . Two ISCSI LIFs per SVM
C
Explanation:
For a two-node cluster serving iSCSI LUNs, it is recommended to create two iSCSI LIFs per node. This configuration provides redundancy and load balancing, ensuring that each node can handle failover scenarios effectively and maintain high availability for the iSCSI connections.
