NEW QUESTION # 42
An administrator creates a new SVM for SAN connectivity on their two-node cluster. The customer needs a redundant configuration at the node layer and fabric layer.
How many LIFs, at minimum, should the administrator create for the SVM?
Answer: D
Explanation:
For a redundant two-node FC SAN configuration, NetApp requires two FC LIFs per node when redundancy must exist across both the node and fabric layers. Each node should have connectivity to both independent fabrics, normally through one FC LIF per fabric. With two controller nodes, this results in four SAN LIFs in total. Although ONTAP can technically support a minimum of one FC LIF per node for an SVM, that would provide only two LIFs and would not satisfy the stated requirement for redundant node-layer and fabric-layer connectivity. NetApp ' s FC SVM configuration guidance specifically states that two LIFs per node and two fabrics provide this redundancy. Relevant SAN ONTAP topics include FC SVM configuration, SAN LIF design, dual-fabric architecture, multipathing, node redundancy, and high availability.

Which two steps must be taken first to restore a LUN from a SnapMirror Synchronous destination? (Choose two.)
Answer: B,D
NEW QUESTION # 44
What are two possible options for iSCSI authentication methods? (Choose two.)
Answer: A,B
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 # 45
A storage engineer zones a new FCP SVM to an SQL cluster.
Which two commands can be used to check connectivity? (Choose two.)
Answer: A,B
Explanation:
ONTAP provides dedicated FCP connectivity tests for validating communication between host initiators and FC LIFs. The vserver fcp ping-igroup show command performs a connectivity check between FCP initiators contained in an igroup and the FCP LIFs through which those initiators are configured to connect. The vserver fcp ping-initiator show command performs the equivalent validation for an individual FC initiator. These commands are therefore appropriate after zoning a new FCP SVM to SQL hosts. cluster ping-cluster validates ONTAP ' s internal cluster network and is unrelated to host-to-storage FC connectivity. network fcp zone show displays discovered FC zoning information but is not the specific FCP initiator connectivity test requested. Relevant SAN ONTAP topics include FC zoning validation, igroups, WWPN connectivity, FCP LIFs, and SAN troubleshooting commands.
NEW QUESTION # 46
A customer has a new eight-node NetApp AFF cluster that will serve NVMe/TCP namespaces to clients.
Bidirectional in-band authentication is required between all NVMe hosts and the AFF cluster.
Which NetApp ONTAP feature must be configured to meet the requirement?
Answer: A
Explanation:
DH-HMAC-CHAP is the ONTAP mechanism for secure in-band NVMe authentication. NetApp documents that ONTAP supports both unidirectional and bidirectional authentication for NVMe/TCP and NVMe/FC by using DH-HMAC-CHAP. For bidirectional mode, a host secret and a controller secret are configured so that the controller authenticates the NVMe host and the host also authenticates the controller. The authentication configuration is associated with the NVMe subsystem host by its NQN. SAML, Kerberos, and an Active Directory domain tunnel are not NVMe transport authentication mechanisms and therefore do not satisfy this requirement. In current ONTAP releases, DH-HMAC-CHAP can be configured through System Manager or the CLI, depending on release. Relevant SAN ONTAP topics are NVMe subsystem host configuration, secure in-band authentication, host/controller secrets, and NVMe/TCP security.
