Enable point-in-time data recovery (Option B): A snapshot freezes the state of a volume at a specific second. If data is subsequently corrupted, deleted, or encrypted by ransomware, the administrator can use the snapshot to restore the data exactly as it was at that "point in time," minimizing data loss.

Create multiple Storage Pools (Option A): A Protection Domain (PD) is a container for nodes. Inside that container, you can define multiple storage pools (e.g., "PD1_Performance_Pool" and "PD1_Capacity_Pool") to segregate media types within the same group of servers.

Monitor fault tolerance compliance (Option B): Since the PD is the boundary for mesh mirroring, you monitor the health and rebuild status at the PD level. If a node fails, you monitor the PD to see the "Rebuild Progress" to ensure fault tolerance is restored.

Incorrect Options: Nodes are grouped for storage (SDS), not metadata management (C). Snapshots (D) are enabled on Volumes, not on the Protection Domain object itself.

This question likely refers to PowerFlex Manager (PFxM) concepts, where "Resource Groups" are used to organize hardware.

Simplifies storage resource management (Option A): Resource Groups allow administrators to logically group disparate hardware (Nodes, Switches) into a single entity. This simplifies operations like upgrades or configuration changes, as you can apply a "Service Template" to the whole group at once.

Allows shared access (Option D): In a multi-tenant environment, Resource Groups allow you to define which administrators or users have access to specific sets of hardware resources (Role-Based Access Control).

Note: "Fault Isolation" (B) is handled by Protection Domains, not Resource Groups.

True: After the initial software deployment (Day 0), the system consists of installed MDM/SDS software but no logical storage structure.

Day 1 Tasks: The administrator's first tasks are to:

Create a Protection Domain (grouping the SDS nodes).

(Optional but recommended) Configure Fault Sets within that Protection Domain for rack awareness.

Create Storage Pools within the PD.

Add Devices (Drives) to the Pool.

Only after these "post-installation" tasks are complete can volumes be created and mapped to hosts.
