 Temperature Sensitive Storage Efficiency (TSSE) is a method of compressing data based on data “temperature”, or how often the data is used. “Cold” data, or data that is not used often, is recompressed with a higher compression ratio for increased storage efficiency. TSSE is enabled automatically on newly created thinly provisioned AFF volumes, not thick provisioned volumes. TSSE operations on AFF arrays are automatically throttled depending on whether data is hot or cold, to balance performance and efficiency. TSSE is not supported on Cloud Volumes ONTAP or ONTAP Select, as these platforms have different storage characteristics and requirements. References :- Temperature-sensitive storage efficiency overview, How does Temperature Sensitive Storage Efficiency affect SnapMirror?, ONTAP Temperature Sensitive Storage Efficiency (TSSE) – A Simple Introduction

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

The easiest and fastest way to restore a single file from a Snapshot copy is to use the Windows Shadow Copy Client, which allows the user to access and restore Data ONTAP Snapshot files from the Previous Versions tab in the Properties menu. This does not require any CLI commands or ONTAP System Manager operations. References :- Restoring files from Snapshot copies, Restore a single file from a Snapshot copy
