The space guarantee setting determines how much space is reserved in the aggregate for the volume. A space guarantee of “none” means that no space is reserved for the volume, and the volume can use any available space in the aggregate. This approach to space management is called thin provisioning. This setting would prevent the hosting aggregates from showing a decrease in available space when creating new volumes, as long as the aggregate is not overcommitted. References :- How volume guarantees work with FlexVol volumes, How you set space guarantees for new or existing volumes, What is the impact of changing volume space-guarantee from “volume” to “none”?

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 point-to-point topology is the simplest and most common way to connect a single host to a storage system using FC. It allows direct communication between two devices without any intermediate devices. The UTA2 ports on the AFF A220 cluster support the point-to-point topology when configured as FC ports. Therefore, to connect a single Windows host directly to the storage using FC, you need to use the point-to-point topology on all ports and make sure that the host and the storage have compatible FC settings, such as speed, WWPN, and zoning. The other options are not correct because they involve additional devices or topologies that are not necessary or supported for this scenario. References :- Quick guide - AFF A220, Detailed guide - AFF A220, ONTAP 9 SAN Configuration Guide
