NEW QUESTION # 95
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: C
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 # 96
A customer is deploying an IP-based SAN on a NetApp AFF All SAN Array (ASA) system. A solution should be used that will increase security and improve reliability.
What is a network best practice for IP-based SAN when implementing AFF ASA infrastructure solutions?
Answer: B
Explanation:
Separate VLANs are a recommended design practice for IP-based SAN traffic because they provide logical network segmentation and enable independent broadcast domains. ONTAP VLANs can separate storage traffic by function or network path even when the underlying physical switching infrastructure is shared. For SAN redundancy, NetApp also recommends separate Ethernet networks and multiple paths so that failure of one network does not eliminate storage connectivity. VLAN separation additionally limits unnecessary broadcast-domain exposure and provides clearer operational boundaries for iSCSI or NVMe/TCP traffic. An MTU of 1500 is supported but does not inherently provide the requested security and reliability improvement, while simply using routed networking is not the relevant SAN best practice. Therefore, separate VLANs provide the appropriate segmentation and path-isolation characteristics for an AFF ASA IP SAN design.
NEW QUESTION # 97
Which two steps must be taken first to restore a LUN from a SnapMirror Synchronous destination? (Choose two.)
Answer: A,B
NEW QUESTION # 98
A customer is migrating FC-mounted VMFS datastores using SnapMirror from their existing NetApp ONTAP cluster to their new ONTAP cluster.
After breaking the SnapMirror relationship on the destination cluster, what does the customer need to do before mapping the LUN to the VMware hosts?
Answer: A
Explanation:
For an FC-attached VMware VMFS datastore migrated through SnapMirror, maintaining the expected LUN identity is critical when presenting the replicated LUN from the destination cluster. VMware uses persistent SCSI device identifiers associated with the LUN, including its serial-based identity, when recognizing an existing VMFS device. ONTAP provides the lun modify -serial capability specifically to modify a LUN serial number. Therefore, after the SnapMirror destination is made writable, the destination LUN ' s serial number must be configured appropriately before the LUN is mapped back to the VMware initiators. Creating a FlexClone, restoring from a Snapshot copy, or changing the LUN OS type does not address device identity.
Relevant SAN ONTAP topics include SnapMirror SAN migration, LUN identity, LUN serial numbers, VMware VMFS, and LUN mapping.
NEW QUESTION # 99
What are two possible options for iSCSI authentication methods? (Choose two.)
Answer: A,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.
