質問 # 84
An administrator connects to a LUN from Node A to a host in a redundant pathing configuration.
How does the administrator show that the LUN delivers data if a node disruption occurs?
正解：D
解説：
A controlled storage takeover and giveback is the appropriate method for validating HA behavior without deliberately creating uncontrolled infrastructure failures. NetApp recommends testing an HA pair after configuration to verify uninterrupted access to storage during takeover and giveback. During takeover, the surviving HA partner assumes responsibility for the affected node ' s storage and continues serving its data.
Host multipathing redirects SAN I/O through surviving paths. Giveback subsequently returns storage ownership and processing to the home node. Pulling cluster-interconnect cables, removing rack power, or disabling backend connectivity introduces unnecessary failure conditions and can affect more infrastructure than required for a controlled validation. Therefore, performing takeover and giveback on the nodes verifies both storage-controller failover and the host ' s redundant SAN path configuration.
質問 # 85
What connectivity Is required between NetApp ONTAP clusters in order to configure SnapMirror active sync across two data centers for FC?
正解：A
解説：
To configure SnapMirror active sync across two data centers using FC (Fibre Channel), the required connectivity between NetApp ONTAP clusters is cluster peering. Cluster peering involves establishing a trust relationship between the clusters, allowing them to replicate data seamlessly. This setup ensures that data synchronization and disaster recovery processes are effective and reliable.
For more detailed information, you can check:
* NetApp Documentation on SnapMirror and Cluster Peering
質問 # 86
What needs to be done to create a consistent Snapshot copy of a LUN without disruptions?
正解：A
解説：
To create a consistent Snapshot copy of a LUN without disruptions, it is necessary to quiesce I/O to the LUN.
This process involves pausing or temporarily stopping the input/output operations to ensure that the data is in a consistent state when the snapshot is taken. This method is crucial for maintaining data integrity and consistency in the snapshot.
For further details, refer to:
* NetApp Documentation on Snapshot Consistency
* NetApp Best Practices for Snapshot Management
質問 # 87
What is used to release space from a NetApp ONTAP LUN when something is removed from within the Windows operating system?
正解：D
解説：
SCSI UNMAP is the mechanism used by a supported SAN host to inform ONTAP that logical blocks within a thin-provisioned LUN are no longer required. Deleting files within Windows normally changes the filesystem
' s allocation information; without storage reclamation, ONTAP may still regard the associated LUN blocks as allocated. When LUN space allocation is enabled and the host supports logical block provisioning, Windows can issue SCSI UNMAP commands identifying unused blocks so ONTAP can return that physical capacity to the available storage pool. A SCSI reservation controls device-access coordination and does not reclaim capacity. Snapshot Autodelete manages Snapshot copies, while SnapCenter provides application-consistent data protection and management. Therefore, SCSI UNMAP is the SAN protocol operation responsible for reclaiming blocks released by the Windows filesystem.
質問 # 88
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?
正解：C
解説：
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.
