NEW QUESTION # 81
Which NetApp ONTAP option enables automatic host-side space management for a LUN?
Answer: A
Explanation:
The space-allocation option enables ONTAP support for SCSI thin-provisioning functions and allows compatible SAN hosts to manage and reclaim unused LUN space. When space allocation is enabled, ONTAP can communicate storage-space conditions to the host and support host-initiated space reclamation through mechanisms such as SCSI UNMAP. NetApp specifically states that enabling space allocation allows SAN hosts to reclaim storage that is no longer being used. space-reserve controls whether physical capacity is reserved for the LUN but does not provide host-side reclamation. resize relates to changing storage size, and alua controls asymmetric path behavior rather than capacity management. Current ONTAP releases enable space allocation by default for many newly created SAN objects. Relevant SAN ONTAP topics include LUN thin provisioning, SCSI UNMAP, space reclamation, and LUN space-allocation configuration.
NEW QUESTION # 82
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 # 83
On a two-node NetApp AFF ASA cluster, what is the recommended minimum number of paths for a SAN environment from the client host perspective?
Answer: B
Explanation:
In a two-node NetApp AFF ASA cluster, the recommended minimum number of paths for a SAN environment from the client host perspective is 4. This configuration ensures high availability and load balancing, which are critical for maintaining performance and resilience in a SAN environment. Each host should have at least two paths to each controller to achieve this setup.
For more detailed information, you can refer to:
* NetApp SAN Configuration
* NetApp All-Flash SAN Array Documentation
NEW QUESTION # 84
A customer has data in a LUN on an existing third-party SAN storage system that will be migrated to a new NetApp AFF A400 all-flash MetroCluster system. The host connected to the LUN is a Windows Server 2019 system.
In this scenario, which two methods are supported? (Choose two.)
Answer: A,B
Explanation:
To migrate data from a LUN on an existing third-party SAN storage system to a new NetApp AFF A400 all- flash MetroCluster system, the supported methods include:
* Foreign LUN Import in online mode: This method allows for data migration without significant downtime, enabling the system to continue serving data while the migration process is ongoing.
* Foreign LUN Import in offline mode: This method involves taking the LUN offline during the migration process, which may be necessary in certain scenarios to ensure data integrity.
For more details, refer to:
* NetApp Documentation on Foreign LUN Import
* NetApp Community on LUN Import Methods
NEW QUESTION # 85
Which two NetApp features provide synchronous data replication between two sites for SAN workloads with automatic failover in case of a site disaster? (Choose two.)
Answer: A,C
Explanation:
For synchronous data replication between two sites with automatic failover in case of a site disaster for SAN workloads, the two NetApp features that provide these capabilities are SnapMirror Synchronous and MetroCluster IP.
* SnapMirror Synchronous: This feature provides volume-granular, synchronous replication with zero RPO (Recovery Point Objective), ensuring that data is mirrored in real-time to a secondary site. This setup supports automatic failover, maintaining data availability even during site failures
* MetroCluster IP: This solution provides synchronous replication and combines high availability and disaster recovery capabilities. MetroCluster IP uses IP networking to extend the distance over which replication can occur and supports automatic failover and failback, making it suitable for critical SAN workloads
