質問 # 36
What are two required components for a NetApp AFF All SAN Array (ASA) A800 MetroCluster IP with automated switchover? (Choose two.)
正解：B、C
解説：
MetroCluster IP uses an IP-based backend infrastructure and supported Ethernet switches rather than the FC switching and FibreBridge architecture associated with MetroCluster FC configurations. The ASA A800 is supported in MetroCluster IP configurations, including deployments using supported Cisco IP switches. For automated unplanned switchover, ONTAP Mediator provides the independent quorum/state mechanism used by MetroCluster IP nodes to determine whether an automatic switchover should occur. NetApp describes Mediator-assisted automatic unplanned switchover (MAUSO) as the MetroCluster IP capability that can initiate switchover following qualifying failures, including complete site failure. ATTO FibreBridge devices and FC switches belong to FC-based MetroCluster topologies and are not the required IP components in this scenario. Consequently, the required choices are Ethernet switches and ONTAP Mediator.
質問 # 37
An administrator is troubleshooting a SAN network issue where the NVMe/TCP LIF keeps disconnecting.
Which command helps the administrator investigate this issue?
正解：B
解説：
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.
質問 # 38
During expansion planning for a 10-node cluster running NetApp ONTAP 9.14.1 software, which uses SAN and NAS, how many additional nodes can be added to this cluster?
正解：B
解説：
NetApp ONTAP 9.14.1 supports up to a 16-node cluster for SAN and NAS configurations. Given a current
10-node cluster, you can add up to 6 additional nodes to reach the maximum supported node count. This expansion capability ensures scalability for growing storage needs while maintaining high availability and performance.

質問 # 39
An administrator finishes an installation of a new NetApp ASA system at the customer site and creates a new LUN. The customer wants to restrict the access of the LUN to specific UFs.
Where would the administrator configure this?
正解：A
解説：
To restrict access to a newly created LUN to specific hosts, the administrator should configure the igroup (initiator group). An igroup is used to control which initiators (hosts) are allowed to access specific LUNs.
This ensures that only authorized hosts can access the storage, enhancing security and access control.
For more details, refer to:
* NetApp Documentation on iGroups ( NetApp ).
質問 # 40
A customer opens a support case for performance issues with an FC Oracle database after migrating from a NetApp AFF system to a NetApp All SAN Array (ASA) platform. Further investigation shows that the number of paths exceeds the recommendation for SAN deployment.
What are two ways to address this problem? (Choose two.)
正解：A、C
解説：
When the number of paths exceeds the recommended configuration for SAN deployment, it can cause performance issues. To address this problem, you can:
* Use Selective LUN Mapping (SLM): SLM allows you to control which LIFs (Logical Interfaces) are used to access specific LUNs, thus reducing the number of paths and potentially improving performance by aligning with best practice configurations.
* Reconfigure the fabric switch zoning: Adjusting the zoning on the fabric switches can help manage and optimize the number of paths, ensuring that there are not too many paths that could lead to inefficient I
/O operations and performance degradation.

* NetApp SAN Host Configuration
