NEW QUESTION # 37
An engineer is troubleshooting FC connectivity issues on a customer's system and sees the following output from the network fcp adapter show command:
According to the output, what is the domain ID of the switch that is connected to port 2a of node n2?
Answer: B
Explanation:
The port address shown for node n2, adapter 2a is 10020. ONTAP reports the FC host port address as a hexadecimal fabric address. Fibre Channel port addresses are interpreted as a 24-bit FC address; when the displayed value is zero-padded to six hexadecimal digits, 10020 becomes 010020. The high-order byte is therefore 01, identifying switch domain ID 1. NetApp's network fcp adapter show command reference confirms that the command reports the Host Port Address and also exposes a domain-id field for the connected fabric. The other choices do not match the domain portion of this FC address. Therefore, the V9.02 supplied answer of D is incorrect for the displayed output. Relevant SAN ONTAP topics are FCP adapter diagnostics, FC port addresses, domain IDs, and fabric connectivity.
NEW QUESTION # 38
A customer is deploying an IP-based SAN on a NetApp AFF All SAN Array (ASA) system. A solution should be used that will increase security and improve reliability.
What is a network best practice for IP-based SAN when implementing AFF ASA infrastructure solutions?
Answer: A
Explanation:
Separate VLANs are a recommended design practice for IP-based SAN traffic because they provide logical network segmentation and enable independent broadcast domains. ONTAP VLANs can separate storage traffic by function or network path even when the underlying physical switching infrastructure is shared. For SAN redundancy, NetApp also recommends separate Ethernet networks and multiple paths so that failure of one network does not eliminate storage connectivity. VLAN separation additionally limits unnecessary broadcast-domain exposure and provides clearer operational boundaries for iSCSI or NVMe/TCP traffic. An MTU of 1500 is supported but does not inherently provide the requested security and reliability improvement, while simply using routed networking is not the relevant SAN best practice. Therefore, separate VLANs provide the appropriate segmentation and path-isolation characteristics for an AFF ASA IP SAN design.
NEW QUESTION # 39
An administrator runs the vserver nvme namespace convert-from-iun command on a NetApp ASA cluster to increase host performance.
What is modified by the convert command?
Answer: A
Explanation:
The vserver nvme namespace convert-from-lun command in a NetApp ASA cluster is used to convert a LUN to an NVMe namespace to increase host performance. This process involves modifying the metadata of the storage object to make it compatible with the NVMe protocol, allowing for faster access and reduced latency
NEW QUESTION # 40
A customer uses several node types in their SAN environment. They want to migrate iSCSI LIFs without disruption.
Which command can achieve this?
Answer: A
Explanation:
ONTAP supports iSCSI LIF migration between nodes specifically on All-Flash SAN Array (ASA) platforms running ONTAP 9.11.1 or later. The migration is restricted to ports on the LIF's home node or its HA partner, and the applicable CLI operation is network interface migrate. Standard AFF and FAS configurations do not provide the same cross-node iSCSI LIF migration capability described in this scenario. For those systems, an iSCSI LIF normally must be created on the required destination node rather than migrated between nodes.
The ucadmin modify command changes unified adapter personality and is unrelated to LIF migration.
Therefore, option D correctly combines the supported ASA platform with the appropriate ONTAP command.
Relevant topics include ASA SAN networking, iSCSI LIF mobility, HA partners, LIF migration, and nondisruptive SAN operations.
NEW QUESTION # 41
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: B
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.
