NEW QUESTION # 82
What does an Active/Optimized path mean in a FAS configuration?
Answer: B
Explanation:
In a traditional FAS SAN configuration, ONTAP uses ALUA to distinguish optimized paths from non- optimized paths. Active/Optimized paths are serviced by the controller associated with the aggregate and LUN being accessed. These paths provide the preferred I/O route because data does not need to be forwarded through another controller. Paths through the HA partner remain available but are normally Active/Non- Optimized and are used when optimized paths become unavailable. NetApp host configuration guidance explicitly describes AFF and FAS systems as having higher-priority Active/Optimized paths serviced by the controller where the aggregate resides and lower-priority non-optimized paths served through another controller. Round-robin is a host multipathing policy and does not define ALUA path state. Relevant topics include ALUA, Active/Optimized paths, Active/Non-Optimized paths, FAS multipathing, and HA architecture.
NEW QUESTION # 83
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 # 84
When using SnapMirror active sync between two clusters, which NetApp service orchestrates failover in case the primary storage system fails?
Answer: C
Explanation:
ONTAP Mediator provides the quorum and health information required for automated failover in a SnapMirror active sync configuration. It operates as an independent third party that monitors communication with both participating ONTAP clusters and provides information that enables ONTAP to determine whether the primary system is unavailable. During an automatic unplanned failover, ONTAP uses Mediator-assisted quorum information before allowing the surviving cluster to serve the protected workload. The Mediator does not carry application data and is not equivalent to MetroCluster Tiebreaker. Active IQ provides monitoring and analytics, while SANtricity manages E-Series storage. NetApp requires a properly configured Mediator for automated failover functionality in applicable SnapMirror active sync configurations. Relevant SAN ONTAP topics include SnapMirror active sync, ONTAP Mediator, quorum, automated unplanned failover, and synchronous replication.
NEW QUESTION # 85
An administrator is setting up a NetApp ONTAP AFF system for both NVMe/TCP and iSCSI. Which task is required for SAN configuration?
Answer: C
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 # 86
An administrator is troubleshooting a SAN network issue where the NVMe/TCP LIF keeps disconnecting.
Which command helps the administrator investigate this issue?
Answer: B
Explanation:
The network port reachability show command is the best troubleshooting choice because it validates Layer-2 reachability for ONTAP Ethernet ports against their expected broadcast domains. NetApp documents that this command reports expected reachability, actual reachability, and conditions such as misconfigured reachability, making it directly useful when an NVMe/TCP LIF repeatedly disconnects because of an underlying network-path or VLAN/broadcast-domain problem. ipspace show only displays IPspace configuration, and vserver nvme subsystem show focuses on NVMe subsystem objects rather than Ethernet path health. cluster ping-cluster tests the cluster network and is not the correct diagnostic for a client-facing NVMe/TCP data LIF. Relevant SAN ONTAP topics are NVMe/TCP networking, Ethernet port reachability, broadcast domains, VLAN connectivity, and SAN network troubleshooting.
