NEW QUESTION # 58
A storage administrator wants to perform online data migration using Foreign LUN Import.
In this scenario, which two conditions are required to support this task? (Choose two.)
Answer: A,B
Explanation:
For an FC-based online Foreign LUN Import, ONTAP requires connectivity on both sides of the migration path. On the backend, ONTAP acts as a SCSI initiator when reading data from the foreign storage array; NetApp therefore specifies that FC FLI requires at least one FC port per controller capable of operating in initiator mode, with redundant ports preferred. On the frontend, the destination ONTAP LUN must be presented to the host so that application I/O can resume while the import continues. For an FCP host, this requires the data SVM to have the FCP service and appropriate FCP LIFs. iSCSI LIFs and iSCSI target definitions are irrelevant to an FC-based FLI workflow. Relevant SAN ONTAP topics include FLI prerequisites, FC initiator ports, FCP LIFs, online FLI, zoning, and host cutover.
NEW QUESTION # 59
A customer has a LUN that is already mapped and connected to a host using FCP. They now want to map the same LUN to another host using iSCSI.
Which two tasks would enable the administrator to share the LUN? (Choose two.)
Answer: A,D
Explanation:
ONTAP igroups can be created with an fcp, iscsi, or mixed protocol type. An iSCSI igroup is therefore valid for presenting the existing LUN specifically to the new iSCSI host. A mixed igroup is also valid because it permits both Fibre Channel and iSCSI initiators and can be used when access to a LUN involves both protocol types. ONTAP permits an igroup to be mapped to multiple LUNs and a LUN to be presented through appropriate SAN igroup mappings. Creating another FC-only igroup would not accommodate the new iSCSI initiator. A subsystem belongs to the NVMe architecture and is used to map NVMe namespaces to NVMe hosts; it is not used for FCP or iSCSI LUN presentation. Thus, both iSCSI and mixed igroups are valid configurations for the requirement.
NEW QUESTION # 60
An administrator installs a new NetApp ONTAP system in a customer ' s SAN environment. The customer wants to confirm that ALUA correctly changes the path states between Active/Optimized and Active
/Nonoptimized.
Which event causes ALUA to change the path states?
Answer: C
Explanation:
ALUA (Asymmetric Logical Unit Access) is a protocol used in SAN environments to manage paths between a host and its storage. It enables the host to recognize and manage paths to the LUNs more efficiently by designating paths as either " Active/Optimized " or " Active/Nonoptimized " . A significant event, such as shutting down all FC LIFs on the HA partner node, will trigger ALUA to change the path states. This action effectively causes the storage paths to transition from the HA partner node to the local node, switching the path states from Active/Nonoptimized to Active/Optimized on the paths that remain active.
For more information, you can refer to:
* NetApp Community Discussion on ALUA
* NetApp Documentation on ALUA
NEW QUESTION # 61
A customer has just purchased new FC adapters to use in their NetApp ONTAP nodes.
Where can the customer verify which slots the cards should be installed in?
Answer: A
Explanation:
NetApp Hardware Universe is the authoritative resource for platform-specific hardware compatibility, supported adapter configurations, and slot priorities. When adding an FC adapter or another I/O module to an ONTAP controller, the administrator must verify that the adapter is supported by the specific controller model and determine the correct or preferred PCIe slot. NetApp installation documentation explicitly directs administrators to Hardware Universe when multiple slots are available so that the documented slot priorities are followed. The Interoperability Matrix Tool validates interoperability among ONTAP releases, hosts, HBAs, drivers, firmware, switches, and related components, but it is not the primary source for controller slot placement. Relevant SAN ONTAP topics include Hardware Universe, controller I/O architecture, FC adapters, PCIe slot priorities, hardware compatibility, and installation planning.
NEW QUESTION # 62
A customer is using a new two-node NetApp All SAN Array (ASA) configuration with SnapMirror active sync. To verify that everything is set up correctly, the customer is reviewing the number of paths on the ESXi hosts.
How many paths should the customer see?
Answer: A
Explanation:
Eight Active/Optimized paths and zero Active/Unoptimized paths is the correct result for the described ASA configuration. NetApp All SAN Array systems use symmetric active-active multipathing, under which all valid paths to a LUN are presented as active and optimized. NetApp's VMware guidance likewise states that ESXi recognizes ASA storage as symmetric and uses the active paths with round-robin multipathing. With SnapMirror active sync and the host connected through the intended redundant paths, the expected path presentation therefore does not contain the Active/Unoptimized paths characteristic of asymmetric access on non-ASA configurations. The key distinction is that ASA pathing is designed to avoid waiting for an ALUA transition after a controller failure. Relevant SAN ONTAP topics are ASA symmetric active-active, ALUA, ESXi multipathing, SnapMirror active sync, and redundant SAN paths.
