NEW QUESTION # 89
A storage administrator wants to perform online data migration using Foreign LUN Import.
In this scenario, which two conditions are required to support this task? (Choose two.)
Answer: A,D
Explanation:
For an FC-based online Foreign LUN Import, ONTAP requires connectivity on both sides of the migration path. On the backend, ONTAP acts as a SCSI initiator when reading data from the foreign storage array; NetApp therefore specifies that FC FLI requires at least one FC port per controller capable of operating in initiator mode, with redundant ports preferred. On the frontend, the destination ONTAP LUN must be presented to the host so that application I/O can resume while the import continues. For an FCP host, this requires the data SVM to have the FCP service and appropriate FCP LIFs. iSCSI LIFs and iSCSI target definitions are irrelevant to an FC-based FLI workflow. Relevant SAN ONTAP topics include FLI prerequisites, FC initiator ports, FCP LIFs, online FLI, zoning, and host cutover.
NEW QUESTION # 90
What is the maximum size for a LUN in NetApp ONTAP 9.14.1 software?
Answer: C
Explanation:
In NetApp ONTAP 9.14.1 software, the maximum size for a LUN is 128TiB. This limit ensures that large datasets can be stored and managed efficiently within a single LUN, catering to the needs of high-capacity SAN environments
NEW QUESTION # 91
A customer has a two-node NetApp ONTAP cluster that Is hosting FC LUNs for 64 SAN hosts. An administrator is tasked to add 40 more hosts to the environment.
What two actions would the administrator need to take to avoid potential performance problems with the environment? (Choose two.)
Answer: A,D
Explanation:
When adding 40 more hosts to a two-node NetApp ONTAP cluster that is already hosting 64 SAN hosts, the following actions are necessary to avoid potential performance problems:
* Configure additional FC target ports: Increasing the number of Fibre Channel (FC) target ports on the storage nodes will help distribute the I/O load more evenly, reducing the risk of bottlenecks.
* Configure additional SAN LIFs: Adding more SAN Logical Interfaces (LIFs) will ensure that the increased number of hosts can connect efficiently, improving load balancing and path management.
These actions help maintain optimal performance and prevent congestion in the SAN environment.

* NetApp SAN Host Configuration Overview
* NetApp Best Practices for SAN ( NetApp ) ( NetApp )
NEW QUESTION # 92
Which two NetApp features enable an administrator to limit the number of paths that a host sees to a LUN?
(Choose two.)
Answer: A,D
Explanation:
Selective LUN Mapping (SLM) and portsets are ONTAP mechanisms specifically used to control the number of paths visible between hosts and mapped LUNs. SLM automatically limits LUN access to paths through the node that owns the LUN and its HA partner, reducing unnecessary paths in larger clusters. A portset provides additional restriction by defining exactly which FCP or iSCSI LIFs an igroup can use to reach its mapped LUNs. NetApp notes that portsets can be combined with SLM when further path restriction is required.
ALUA identifies optimized and non-optimized paths but does not itself reduce the number of visible paths.
An igroup controls which initiators can access a LUN but does not independently restrict target LIF visibility.
Relevant topics include SLM, portsets, igroups, SAN multipathing, and path-count optimization.
NEW QUESTION # 93
What is used to release space from a NetApp ONTAP LUN when something is removed from within the Windows operating system?
Answer: B
Explanation:
SCSI UNMAP is the mechanism used by a supported SAN host to inform ONTAP that logical blocks within a thin-provisioned LUN are no longer required. Deleting files within Windows normally changes the filesystem
' s allocation information; without storage reclamation, ONTAP may still regard the associated LUN blocks as allocated. When LUN space allocation is enabled and the host supports logical block provisioning, Windows can issue SCSI UNMAP commands identifying unused blocks so ONTAP can return that physical capacity to the available storage pool. A SCSI reservation controls device-access coordination and does not reclaim capacity. Snapshot Autodelete manages Snapshot copies, while SnapCenter provides application-consistent data protection and management. Therefore, SCSI UNMAP is the SAN protocol operation responsible for reclaiming blocks released by the Windows filesystem.
