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
