NEW QUESTION # 44
A customer wants to use NVMe/FC to connect three Linux hosts to their NetApp ONTAP cluster.
What is the minimum speed for an HBA in an ONTAP controller in this scenario?
Answer: D
Explanation:
The required controller-side FC adapter capability for the NVMe/FC configuration represented by this question is 32 Gbps. NetApp's NVMe/FC implementation for the relevant ONTAP platforms uses supported
32 Gb FC target adapters, and NetApp platform specifications identify NVMe/FC connectivity through 32 Gbps FC ports. NetApp's NVMe/FC documentation also identifies supported Linux host configurations using
32 Gb Fibre Channel adapters, with exact host adapter, firmware, driver, switch, and ONTAP combinations validated through the Interoperability Matrix Tool. Traditional 4, 8, or 16 Gbps FC adapters may support conventional FCP on applicable platforms, but they do not meet the NVMe/FC controller-adapter requirement tested here. Relevant SAN ONTAP topics include NVMe/FC, 32 Gb FC target adapters, HBAs, Fibre Channel fabrics, and IMT validation.
NEW QUESTION # 45
A customer opens a support case for performance issues with an FC Oracle database after migrating from a NetApp AFF system to a NetApp All SAN Array (ASA) platform. Further investigation shows that the number of paths exceeds the recommendation for SAN deployment.
What are two ways to address this problem? (Choose two.)
Answer: A,B
Explanation:
When the number of paths exceeds the recommended configuration for SAN deployment, it can cause performance issues. To address this problem, you can:
* Use Selective LUN Mapping (SLM): SLM allows you to control which LIFs (Logical Interfaces) are used to access specific LUNs, thus reducing the number of paths and potentially improving performance by aligning with best practice configurations.
* Reconfigure the fabric switch zoning: Adjusting the zoning on the fabric switches can help manage and optimize the number of paths, ensuring that there are not too many paths that could lead to inefficient I
/O operations and performance degradation.

* NetApp Best Practices for SAN
NEW QUESTION # 46
An administrator is troubleshooting a SAN network issue where the NVMe/TCP LIF keeps disconnecting.
Which command helps the administrator investigate this issue?
Answer: C
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.
NEW QUESTION # 47
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 # 48
A customer currently operates a legacy iSCSI storage environment that is connected to network switches with several Windows hosts. As part of an upcoming NetApp ONTAP software upgrade, an engineer needs to verify compatibility.
Which two NetApp tools would help the engineer assess the environment? (Choose two.)
Answer: B,C
Explanation:
To verify compatibility in an iSCSI storage environment before a NetApp ONTAP software upgrade, the following tools are recommended:
* Interoperability Matrix Tool (IMT): This tool helps verify the compatibility of different components, including network switches, hosts, and storage systems, ensuring that the planned upgrade will be supported.
* Active IQ OneCollect: This tool collects comprehensive configuration and performance data from the storage environment, which can be used to assess the current setup and identify any compatibility issues before the upgrade.
For further details, refer to:
* NetApp Interoperability Matrix Tool
* Active IQ OneCollect Documentation
