An admin is setting up replication and has set up a Protection Group.

When setting up replication on a Pure Storage FlashArray, an admin creates aProtection Groupto define which entities will be replicated to a remote FlashArray. When adding members to a Protection Group, there are three valid choices:Volumes,Snapshots, andHost Groups. Here's a breakdown of each option:

Choices for Adding Members:

Add Volumes:

Volumes are the primary entities that can be added to a Protection Group. Replication ensures that the data within these volumes is copied to the remote FlashArray.

This is the most common use case for replication, especially for protecting critical data such as databases or virtual machine disks.

Add Snapshots:

Snapshots of volumes can also be added to a Protection Group. This allows point-in-time copies of the data to be replicated to the remote array.

Snapshots are useful for disaster recovery scenarios where you need to restore data to a specific point in time.

Add Host Groups:

Host Groups can be added to a Protection Group to replicate all volumes associated with the host group. This simplifies management when multiple volumes are tied to a single application or server.

Replicating Host Groups ensures that all related volumes are protected together, maintaining consistency across the workload.

Incorrect Options:

A. Add Hosts:

Hosts themselves cannot be directly added to a Protection Group. Instead, replication focuses on the data (volumes) or logical groupings (host groups) associated with the hosts.

E. Add HBA WWN:

HBA WWNs (World Wide Names) are identifiers for Fibre Channel adapters and are not relevant to replication or Protection Groups. They are used for zoning and connectivity but do not play a role in defining replication members.

Final Recommendation:

The correct options areB. Add Volumes,C. Add Snapshots, andD. Add Host Groups, as these are the valid entities that can be added to a Protection Group for replication.
