NEW QUESTION # 10
What will enable iSCSI multipathing on a new Windows Server 2022?
Answer: B
Explanation:
NetApp Windows Host Utilities are used to configure Windows hosts correctly for ONTAP SAN storage and include support for Microsoft Multipath I/O configuration. During Host Utilities installation, multipathing support can be selected when multiple paths exist between the Windows server and the storage system. The package also configures required Windows registry and storage parameters so the host correctly handles ONTAP pathing behavior. Device Mapper Multipathing is primarily associated with Linux and is therefore inappropriate for Windows Server. An iSCSI target represents the storage endpoint and does not itself configure host multipathing. ANA is the NVMe multipathing mechanism and does not apply to an iSCSI LUN. Relevant SAN ONTAP topics include Windows Host Utilities, Microsoft MPIO, iSCSI host configuration, ALUA, redundant SAN paths, and Windows Server interoperability.
NEW QUESTION # 11
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 # 12
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: B,C
Explanation:
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.
For more details, see:
* NetApp Documentation on Consistency Groups
* NetApp FlexGroup Overview
NEW QUESTION # 13
A customer has demanding database servers that require larger I/O queue counts and queue depths.
What should be done to increase these parameters for certain hosts?
Answer: D
Explanation:
Adding the selected hosts to the NVMe subsystem with high priority is the correct method because ONTAP host priority controls the NVMe I/O queue resources assigned to a host. NetApp's NVMe subsystem model defines the host priority setting as allocating appropriate I/O queue counts and queue depths for the host to submit I/O commands. Therefore, demanding database hosts that require larger queue counts and deeper queues should receive the higher host-priority setting rather than changing a volume QoS policy. QoS governs workload throughput or performance limits and does not directly redefine the NVMe host submission-queue count and depth. Likewise, queue depth is not configured on an individual namespace in the manner described by option D. Relevant SAN ONTAP topics are NVMe subsystems, host priority, I/O queue count, I/O queue depth, and host performance configuration.
NEW QUESTION # 14
An administrator is troubleshooting a SAN network issue where the NVMe/TCP LIF keeps disconnecting.
Which command helps the administrator investigate this issue?
Answer: D
Explanation:
The network port reachability show command is the best troubleshooting choice because it validates Layer-2 reachability for ONTAP Ethernet ports against their expected broadcast domains. NetApp documents that this command reports expected reachability, actual reachability, and conditions such as misconfigured reachability, making it directly useful when an NVMe/TCP LIF repeatedly disconnects because of an underlying network-path or VLAN/broadcast-domain problem. ipspace show only displays IPspace configuration, and vserver nvme subsystem show focuses on NVMe subsystem objects rather than Ethernet path health. cluster ping-cluster tests the cluster network and is not the correct diagnostic for a client-facing NVMe/TCP data LIF. Relevant SAN ONTAP topics are NVMe/TCP networking, Ethernet port reachability, broadcast domains, VLAN connectivity, and SAN network troubleshooting.
