NEW QUESTION # 10
What are two possible options for iSCSI authentication methods? (Choose two.)
Answer: B,D
Explanation:
ONTAP defines the supported iSCSI authentication types as CHAP, deny, and none. Therefore, among the options provided, CHAP and deny are the two valid choices. CHAP authenticates an initiator by using a username and password. ONTAP supports inbound CHAP, where the storage system authenticates the initiator, and optional outbound CHAP for mutual authentication. The deny authentication type explicitly prevents the specified initiator from accessing the SVM. Certificates and SAML are not available values for ONTAP iSCSI initiator authentication. The vserver iscsi security create command exposes the authentication type as {CHAP|deny|none}. Consequently, the V9.02 supplied answer A, B is incorrect and has been corrected to A, C. Relevant topics include iSCSI security, CHAP, mutual CHAP, initiator credentials, and authentication policies.
NEW QUESTION # 11
After a storage administrator creates a LUN using the CLI, the LUN does not appear on the corresponding host.
What should be done to correct this issue?
Answer: A
Explanation:
A LUN created with the ONTAP CLI is not automatically visible to a host merely because the storage object exists. For FCP or iSCSI access, ONTAP must associate the LUN with an initiator group by creating a LUN mapping. NetApp's SAN provisioning workflow explicitly creates the LUN, creates or identifies the igroup containing the host initiators, and then maps the LUN to that igroup. The mapping assigns host access and a LUN ID that the initiator uses to discover the device. Bringing the LUN online does not grant host access, mounting a volume is not part of SAN LUN presentation, and export policies apply to NAS protocols rather than FCP/iSCSI LUN access. Relevant SAN ONTAP topics are LUN provisioning, igroups, LUN mapping, LUN IDs, and host discovery.
NEW QUESTION # 12
An administrator needs to ensure that Snapshot copies of database files across multiple FCP LUNs are taken at the same point in time.
Which two configurations enable the administrator to achieve this? (Choose two.)
Answer: C,D
Explanation:
To ensure that Snapshot copies of database files across multiple FCP LUNs are taken at the same point in time, the following configurations can be used:
* Create a consistency group that uses FlexVol volumes: This setup ensures that snapshots of all volumes in the consistency group are taken simultaneously.
* Create each LUN within the same FlexGroup volume: This configuration allows for a unified snapshot across multiple LUNs within the FlexGroup, ensuring data consistency.
For more details, see:
* NetApp Documentation on Consistency Groups
* NetApp FlexGroup Overview
NEW QUESTION # 13
An administrator is deploying a new SAN workload that has a NetApp All SAN Array (ASA) cluster. The customer wants to reclaim space by tiering to Azure Blob storage.
According to NetApp best practices, which volume tiering policy should be applied?
Answer: C
Explanation:
The Auto FabricPool tiering policy permits ONTAP to identify cold blocks in both the active filesystem and Snapshot data and move those blocks from the performance tier to the configured object-store capacity tier, including Microsoft Azure Blob Storage. Unlike the all policy, Auto does not immediately classify all blocks as cold; active data remains on the performance tier until it satisfies the cooling criteria. The default cooling period for Auto is 31 days and can be adjusted within supported limits. snapshot-only restricts tiering primarily to Snapshot-related blocks, while none prevents additional blocks from being tiered. Because the customer specifically wants to reclaim performance-tier capacity while retaining active SAN workload behavior, the Auto policy provides the appropriate balance between cloud-tier space reclamation and performance.
NEW QUESTION # 14
Which NetApp ONTAP option enables automatic host-side space management for a LUN?
Answer: C
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.
