NEW QUESTION # 104
What configuration must be applied for NVMe/FC?
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.
For further details, you can refer to:
* NetApp Community - NVMe/FC Configuration ( NetApp Community ).
* NetApp Documentation - NVMe Overview ( NetApp ).
NEW QUESTION # 105
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?
Answer: 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.

NEW QUESTION # 106
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.)
Answer: C,D
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
NEW QUESTION # 107
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: C
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 # 108
After a storage administrator creates a LUN using the CLI, the LUN does not appear on the corresponding host.
What should be done to correct this issue?
Answer: D
Explanation:
A LUN created with the ONTAP CLI is not automatically visible to a host merely because the storage object exists. For FCP or iSCSI access, ONTAP must associate the LUN with an initiator group by creating a LUN mapping. NetApp's SAN provisioning workflow explicitly creates the LUN, creates or identifies the igroup containing the host initiators, and then maps the LUN to that igroup. The mapping assigns host access and a LUN ID that the initiator uses to discover the device. Bringing the LUN online does not grant host access, mounting a volume is not part of SAN LUN presentation, and export policies apply to NAS protocols rather than FCP/iSCSI LUN access. Relevant SAN ONTAP topics are LUN provisioning, igroups, LUN mapping, LUN IDs, and host discovery.
