質問 # 30
A storage administrator has just completed an ISCSI implementation in a customer environment running VMware and needs to validate that the entire network path supports jumbo frames.
Which action should be taken?
正解：C
解説：
To validate that the entire network path supports jumbo frames after an iSCSI implementation, you should perform a ping test from the host with fragmentation. This involves using the ping command with specific options to test jumbo frame support:
ping -M do -s 8972 < target_IP >
In this command:
* -M do ensures the packets are not fragmented.
* -s 8972 sets the packet size to 8972 bytes (9000 bytes MTU minus 28 bytes for the ICMP header).
By confirming that the large packets are successfully transmitted without fragmentation, you can validate that the network path, including switches and adapters, supports jumbo frames.
For more details, you can check:
* NetApp Documentation - iSCSI Configuration and Best Practices ( NetApp ) ( NetApp ).

A customer wants a NetApp ONTAP All SAN Array (ASA) cluster set up with a redundant Ethernet configuration.
What needs to be configured to achieve this?
正解：B
解説：
IP SAN redundancy requires independent storage paths between each host and both nodes of the HA pair.
NetApp SAN networking guidance recommends creating multiple iSCSI paths from each node and specifically allows two data LIFs per node to provide connectivity through separate Ethernet networks. These networks should use separate IP subnets or ranges so that loss of one network, switch, port, or path does not eliminate host access to the storage. Host-side MPIO then uses the remaining paths during a failure. A node- management LIF provides administrative connectivity and is not a redundant data path. Selective LUN Mapping controls which cluster nodes report a LUN, while separate SVMs are not required merely to create network redundancy. Therefore, at least two data LIFs per node across separate IP networks provide the requested redundant Ethernet SAN configuration.
質問 # 32
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?
正解：B
解説：
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.
質問 # 33
What will enable iSCSI multipathing on a new Windows Server 2022?
正解：D
解説：
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.
質問 # 34
A storage administrator wants to increase security and optimize performance in a recently implemented SAN deployment.
What should the storage administrator configure to ensure initiator restriction to certain LIFs?
正解：A
解説：
To increase security and optimize performance in a SAN deployment, configuring an access list is essential.
Access lists restrict initiator access to specific LIFs, ensuring that only authorized hosts can connect to the storage system. This helps in enhancing security by preventing unauthorized access and optimizes performance by controlling and managing the paths used for storage access.
