NEW QUESTION # 57
A customer wants a NetApp ONTAP All SAN Array (ASA) cluster set up with a redundant Ethernet configuration.
What needs to be configured to achieve this?
Answer: B
Explanation:
IP SAN redundancy requires independent storage paths between each host and both nodes of the HA pair.
NetApp SAN networking guidance recommends creating multiple iSCSI paths from each node and specifically allows two data LIFs per node to provide connectivity through separate Ethernet networks. These networks should use separate IP subnets or ranges so that loss of one network, switch, port, or path does not eliminate host access to the storage. Host-side MPIO then uses the remaining paths during a failure. A node- management LIF provides administrative connectivity and is not a redundant data path. Selective LUN Mapping controls which cluster nodes report a LUN, while separate SVMs are not required merely to create network redundancy. Therefore, at least two data LIFs per node across separate IP networks provide the requested redundant Ethernet SAN configuration.
NEW QUESTION # 58
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 ).
NEW QUESTION # 59
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: B
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.
NEW QUESTION # 60
A customer wants to enable CHAP authentication on their iSCSI sessions.
Which command should be used to set up the appropriate security policies and passwords?
Answer: B
Explanation:
To enable CHAP (Challenge-Handshake Authentication Protocol) authentication on iSCSI sessions, the command vserver iscsi security create should be used. This command sets up the necessary security policies and passwords required for CHAP authentication, ensuring secure access to iSCSI targets.
For more details, refer to:
* NetApp Documentation on iSCSI Configuration ( NetApp ).
NEW QUESTION # 61
A customer deploys an SVM for FCP with four LIFs across two fabrics. Equal client traffic is seen across all four LIFs.
In this scenario, how is the traffic across the active, unoptimized paths forwarded to the node hosting the LUN?
Answer: A
Explanation:
In a traditional AFF or FAS SAN configuration using ALUA, paths through the controller that owns the LUN are reported as Active/Optimized. Paths entering through another controller can be Active/Non-Optimized.
When I/O arrives through an active, non-optimized path, ONTAP must forward that I/O internally to the node servicing the LUN. This indirect data path uses the ONTAP cluster interconnect, represented in the choices as the cluster network, and therefore introduces additional latency compared with a direct optimized path. The external FC fabric transports traffic only as far as the target LIF; the HA interconnect is associated primarily with HA-pair storage failover functions, and the peering network is used for intercluster communications and replication. Relevant SAN ONTAP topics include ALUA, optimized versus non-optimized paths, cluster interconnect forwarding, SLM, and FCP multipathing.
