71. Frage
What are two benefits of implementing VLANs for NVMe/TCP configurations? (Choose two.)
Antwort: A,D
Begründung:
Implementing VLANs for NVMe/TCP configurations provides several benefits, two of which are increased resiliency and increased security:
* Increased Resiliency: VLANs help segment the network traffic, reducing the risk of a single point of failure. By isolating NVMe/TCP traffic into specific VLANs, network issues can be contained within a VLAN, preventing them from affecting other parts of the network. This isolation ensures that disruptions are minimized and network resiliency is enhanced.
* Increased Security: VLANs provide an added layer of security by segregating traffic. This segregation ensures that NVMe/TCP traffic is isolated from other types of traffic, reducing the risk of unauthorized access or data breaches. VLANs help in enforcing stricter access controls and monitoring, thereby increasing the overall security of the network.
For more information on the benefits of VLANs in NVMe/TCP configurations, you can refer to NetApp ' s technical resources:
* Implementing and Configuring Modern SANs with NVMe-oF ( NetApp ).
* SAN Configuration Best Practices ( NetApp Community ).
72. Frage
Where is the zoning configuration stored in an FC SAN environment?
Antwort: A
Begründung:
Fibre Channel zoning is configured and maintained within the FC switching fabric. ONTAP hosts and storage LIFs provide WWPN identities, but the switch configuration determines which initiator and target ports are permitted to communicate. NetApp's FC zoning guidance instructs administrators to log in to the FC switch administration interface, create zones containing host initiator WWPNs and ONTAP FC LIF WWPNs, save the zones, and activate the resulting zone configuration. Cisco environments use zones and zonesets, while comparable constructs exist on Broadcom/Brocade fabrics. Neither the host HBA nor the ONTAP storage system stores the authoritative fabric zoning configuration. Therefore, the FC switches are the correct location. Relevant SAN ONTAP topics include FC fabric design, WWPN zoning, zonesets, dual-fabric configurations, and SAN connectivity.
73. Frage
What Is the storage construct that enables an NVMe client to store data in an SVM?
Antwort: B
Begründung:
In an NVMe environment, the storage construct that enables an NVMe client to store data in an SVM (Storage Virtual Machine) is a Subsystem. A subsystem is a collection of one or more namespaces, which are used to store data. This abstraction allows for efficient management and scaling of NVMe storage within the ONTAP environment.

74. Frage
When using tagged VLANs on Cisco Nexus switches for NVMe over TCP, which two changes must be made to enable jumbo frames? (Choose two.)
Antwort: A,C
Begründung:
For enabling jumbo frames on Cisco Nexus switches for NVMe over TCP with tagged VLANs, the following changes are required:
* Modify the Cisco Nexus switches to use an MTU of 9216: Setting the MTU to 9216 ensures that the network can handle jumbo frames, reducing the number of packets needed for large data transfers and thus improving performance.
* Modify the appropriate broadcast domain in NetApp ONTAP software to use an MTU of 9216: This setting must match the network configuration to ensure end-to-end support for jumbo frames, which is essential for optimizing performance in NVMe over TCP environments.
For additional information, refer to:
* NetApp Documentation on NVMe over TCP
* Cisco Documentation on Jumbo Frames
75. Frage
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?
Antwort: D
Begründung:
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 ).
