Which of the following is not a function of the DPC client?

Question

Options

• AStorage space allocation
• BLoad balancing
• CEC operation
• D1/0 addressing

• A
  83% (19)
• B
  4% (1)
• C
  4% (1)
• D
  9% (2)

Explanation

Storage space allocation belongs to a higher-level storage management layer - typically a metadata server, volume manager, or storage controller - not the DPC (Data Path Controller/Client). The DPC client operates at the data path level, handling how I/O flows through the system, not how capacity is provisioned or partitioned.

Why the distractors are wrong:

• B (Load balancing) is a core DPC client responsibility - it distributes I/O requests across available resources to prevent bottlenecks.
• C (EC operation) - Erasure Coding (or Error Correction) is handled at the data path level, making it a DPC client function for data protection and reconstruction.
• D (I/O addressing) is fundamental to the DPC client's role - it translates logical I/O requests into physical addresses to locate and access data.

Memory tip: Think of the DPC client as the traffic director for data - it routes, balances, checks, and addresses. Storage allocation (deciding how much space exists and where) is a management-plane concern, not a data-plane concern. If the function sounds like "managing capacity," it's not the DPC client's job.
