To utilize Fault Sets effectively for their intended purpose (rack-level fault tolerance), the cluster architecture imposes specific minimums.

PowerFlex relies on distributing data copies (Mesh Mirroring). The standard redundancy scheme creates 2 copies of data. To ensure that data remains available even if one entire Fault Set (e.g., an entire rack) fails, the system must be able to distribute the mirrors across different Fault Sets. Consequently, you generally need a minimum of 3 Fault Sets (System requires 3+ Fault Sets to support 2-copy layouts effectively). Since a Fault Set must contain at least one node, the cluster requires a minimum of 3 nodes to support a Fault Set configuration.

These tasks are handled by the Snapshot Policy feature in PowerFlex.

Scheduling snapshot creation (Option A): Administrators can define a policy (e.g., "Gold Policy") that triggers a snapshot every 15 minutes. Once applied to a volume, the system automates this trigger.

Managing snapshot retention policies (Option C): The policy also dictates the lifecycle of the snapshot. For example, "Keep 10 hourly snapshots and 5 daily snapshots." As new snapshots are created, the system automatically deletes the oldest ones to free up space and maintain the defined retention count.

Incorrect Options:

Assigning to Fault Sets (B): Snapshots reside in the same Storage Pool as the source volume; they are not assigned to Fault Sets.

Automating replication (D): While replication uses snapshots, the Snapshot Policy feature itself is distinct from the Replication Consistency Group configuration.

In PowerFlex terminology, the Storage Data Server (SDS) acts as the "Target" for I/O operations.

Organize drives for storage pools (Option B): The SDS takes ownership of the local physical drives (NVMe/SSD/HDD) installed in the server. It aggregates these drives and contributes them to the Storage Pool. It handles the reading and writing of data blocks to this physical media.

Incorrect Options: Metadata is managed by the MDM (A). Access to external resources (C) is not the function of the SDS (which provides internal storage). Deduplication (D) is a specific feature, not the primary function of the component.
