Question

Options

• A1 - A
• B1 - A
• C1 - D
• D1 - A

• A
  3% (1)
• B
  89% (31)
• C
  3% (1)
• D
  6% (2)

Explanation

Option B is correct because it correctly maps Protection Domain (Entity 1) to Function A - which represents its role as the top-level administrative boundary in PowerFlex that groups Storage Data Servers (SDSs) and governs data protection policies across the system. Protection Domains define the scope within which storage resources are managed and protected, making them the foundational organizational unit.

Why the distractors fail: Choice C is wrong because mapping Entity 1 to Function D would assign Protection Domain a role (likely associated with Fault Sets - grouping SDSs that share a physical failure point like a rack or chassis) that belongs to a different entity. Choices A and D, while showing the same mapping as B on the surface, represent incorrect pairings for the remaining entities (Storage Pool, Fault Set, Resource Group) elsewhere in the full match set, making the overall answer wrong even if one line appears identical.

Memory tip: Think of PowerFlex entities as nested layers - Protection Domain is the outer fence (broadest boundary), Storage Pool is the bucket inside collecting raw capacity, Fault Set is the risk tag grouping hardware that could fail together, and Resource Group is the label for logical management grouping. Hierarchy = Domain → Pool → (Fault Set informs placement; Resource Group manages access).
