NEW QUESTION # 12
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?
Answer: D
Explanation:
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.
NEW QUESTION # 13
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?
Answer: C
Explanation:
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.
For additional details, you can refer to:
* NetApp SAN Administration Guide
NEW QUESTION # 14
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 # 15
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 # 16
An administrator is setting up a NetApp ONTAP AFF system for both NVMe/TCP and iSCSI. Which task is required for SAN configuration?
Answer: A
Explanation:
When setting up a NetApp ONTAP AFF system for both NVMe/TCP and iSCSI, a critical task required for SAN configuration is to configure Logical Interfaces (LIFs). LIFs are necessary for network connectivity and are used by both NVMe/TCP and iSCSI protocols to communicate between the storage system and the host.
The configuration of LIFs involves creating and managing these interfaces to ensure they are correctly mapped and available for use by the respective protocols. This step is essential for the SAN setup to function properly.
For more detailed steps on configuring LIFs, you can refer to NetApp ' s documentation:
* How to Configure NVMe/TCP with ONTAP ( NetApp Community ).
* SAN Configuration with ONTAP ( NetApp ).
