During an iSCSI deployment, the customer requests a change of front-end network connections on the NetApp ONTAP cluster from twinax cables to fiber-optic cables.
Which two NetApp tools would an administrator use to verify the supported port speeds and transceivers? (Choose two.)

  1. Hardware Universe to determine supported transceivers
  2. Interoperability Matrix Tool to determine supported transceivers
  3. Hardware Universe to determine supported port speeds
  4. Interoperability Matrix Tool to determine supported port speeds

Answer(s): A,B

Explanation:

During an iSCSI deployment, if a customer requests a change from twinax cables to fiber-optic cables, two NetApp tools can be used to verify the supported port speeds and transceivers:
Hardware Universe (HWU): This tool is essential for determining the supported transceivers and port speeds for NetApp hardware. It provides detailed information on hardware compatibility, including supported transceivers, cables, and port speeds, which helps ensure that the selected components are compatible with the NetApp storage system.
Interoperability Matrix Tool (IMT): The IMT provides comprehensive compatibility information between NetApp products and third-party components. It includes details on supported transceivers and port speeds, ensuring that any changes made to the network connections are supported and will function correctly in the given configuration.

For more detailed information, you can refer to the following resources:
NetApp Hardware Universe(NetApp).
NetApp Interoperability Matrix Tool(NetApp).



An administrator has a NetApp AFF cluster with two SVMs serving LUNs. SnapMirror active sync is configured, and a disaster recovery test is planned over the weekend.
Which NetApp ONTAP command will show the status of this test?

  1. snapmirror failover show
  2. network interface failover-groups show
  3. storage failover hwassist show
  4. snapnirror config-replication status show

Answer(s): A

Explanation:

To check the status of a SnapMirror active sync disaster recovery test on a NetApp ONTAP cluster, you would use the command snapmirror failover show. This command provides the necessary details about the failover status, helping administrators verify if the disaster recovery test is proceeding as expected. It displays the status of the failover groups and their readiness, which is essential for confirming the effectiveness of the disaster recovery setup. For more detailed information on SnapMirror commands and their usage, refer to:
NetApp Documentation - SnapMirror Commands(NetApp Community)(NetApp Community).



What configuration must be applied for NVMe/FC?

  1. Create multiple initiator zones and multiple target zones.
  2. Configure igroup and IQN mapping.
  3. Enable NPV on all fabric switches.
  4. Enable NPIV on all fabric switches.

Answer(s): D

Explanation:

When configuring NVMe/FC (NVMe over Fibre Channel), it is necessary to enable N_Port ID Virtualization (NPIV) on all fabric switches. NPIV allows multiple Fibre Channel initiators to share a single physical Fibre Channel port, which is crucial for NVMe/FC environments where efficient utilization of available ports is needed.
NPIV support enables the creation of virtual ports, which can significantly optimize the configuration and management of Fibre Channel fabrics, thus supporting NVMe/FC operations.
For further details, you can refer to:
NetApp Community - NVMe/FC Configuration(NetApp Community).
NetApp Documentation - NVMe Overview(NetApp).



A storage administrator has just completed an ISCSI implementation in a customer environment running VMware and needs to validate that the entire network path supports jumbo frames.
Which action should be taken?

  1. Ping from the host with fragmentation.
  2. Check the VMkernel adapter settings.
  3. Ping from the host without fragmentation.
  4. Check the broadcast domain settings.

Answer(s): A

Explanation:

To validate that the entire network path supports jumbo frames after an iSCSI implementation, you should perform a ping test from the host with fragmentation. This involves using the ping command with specific options to test jumbo frame support:

ping -M do -s 8972 <target_IP>
In this command:
-M do ensures the packets are not fragmented.
-s 8972 sets the packet size to 8972 bytes (9000 bytes MTU minus 28 bytes for the ICMP header). By confirming that the large packets are successfully transmitted without fragmentation, you can validate that the network path, including switches and adapters, supports jumbo frames.
For more details, you can check:
NetApp Documentation - iSCSI Configuration and Best Practices(NetApp)(NetApp).
