Netapp NS0-162 Exam With Confidence Using Practice Dumps

The performance capacity report shows the current and optimal performance metrics for the CPU resource on each node of the cluster. The current metrics reflect the actual workload on the resource, while the optimal metrics reflect the workload that would result in the best performance. The performance capacity, or headroom, is the difference between the current and optimal metrics. A low or negative headroom indicates that the resource is over utilized and may experience performance degradation. The exhibit shows that both nodes have negative headroom for the CPU resource, which means that the CPU has been over utilized. A storage failover event will cause performance issues, as the surviving node will have to handle the workload of both nodes, which will further reduce the headroom and increase the latency. References :- Identify remaining performance capacity, What is Performance Capacity in ONTAP 9 and Unified Manager?

When you set up an ONTAP cluster, the cluster setup process automatically creates the admin SVM and the node SVMs for the cluster. The admin SVM represents the cluster and provides cluster-wide management services. The node SVMs represent the individual nodes of the cluster and provide node-specific management services. The data SVMs and the cluster SVMs are not automatically created, but can be created manually or by using the System Manager GUI. The data SVMs provide data access to the clients and applications using various protocols. The cluster SVMs provide intercluster communication and data replication between clusters12. References :- Types of SVMs, ONTAP - Types of SVMs

The auto-revert option determines whether a LIF automatically reverts to its home port after a failover event. If this option is set to true, the LIF will revert to its home port when it becomes available. If this option is set to false, the LIF will remain on the failover port until manually reverted. In this scenario, the cluster LIFs are not on their home ports after an ONTAP upgrade, which might have triggered a failover event. Therefore, setting the auto-revert option to true would change this outcome and ensure that the LIFs return to their home ports after the upgrade. References :- network interface modify, Verify all LIFS are on home ports after ONTAP upgrade
