A Protection Group in Pure Storage Purity//FA is a logical container used to apply consistent data protection policies, such as snapshot schedules and replication, to a group of related storage objects. When an administrator adds members to a Protection Group, the available object types are individual volumes, hosts, and host groups. Adding a host or a host group as a member automatically includes all volumes currently connected to that host or group, ensuring that all components of an application are protected with crash-consistency.

C. Add Snapshots: Snapshots are the result of a protection policy being applied to the members of a Protection Group; they are not objects that can be added as members.

E. Add HBA WWN: An HBA WWN (Host Bus Adapter World Wide Name) is a hardware identifier for Fibre Channel connectivity and is not a manageable object that can be directly added to a Protection Group.
