CV0-003 Question #265: Real Exam Question with Answer & Explanation

The correct answer is D: Compression 1.8:1Deduplication 2.7:1Overall savings 4.2:1Average latency 1.2ms. The two stated requirements are (1) 4:1 overall storage efficiency and (2) sub-millisecond latency (strictly less than 1ms = less than 1000 microseconds). Evaluating each option: Option A achieves 4:1 efficiency but 1.0ms latency, which is not sub-millisecond. Option B achieves o

Question

A cloud administrator has deployed a new all-flash storage array with deduplication and compression enabled, and moved some of the VMs into it. The goal was to achieve 4:1 storage efficiency while maintaining sub-millisecond latency. Which of the following results would BEST suit the requirements?

Options

  • ACompression 1:1Deduplication 4:1Overall savings 4:1Average latency 1.0ms
  • BCompression 1.5:1Deduplication 1.8:1Overall savings 2.2:1Average latency 600us
  • CCompression 1.3:1Deduplication 3.1:1Overall savings 4.3:1Average latency 900us
  • DCompression 1.8:1Deduplication 2.7:1Overall savings 4.2:1Average latency 1.2ms

Explanation

The two stated requirements are (1) 4:1 overall storage efficiency and (2) sub-millisecond latency (strictly less than 1ms = less than 1000 microseconds). Evaluating each option: Option A achieves 4:1 efficiency but 1.0ms latency, which is not sub-millisecond. Option B achieves only 2.2:1 efficiency, failing the storage goal. Option C achieves 4.3:1 overall savings (exceeding the 4:1 target) with 900us latency (which IS sub-millisecond, since 900us < 1000us). Option D achieves 4.2:1 efficiency but 1.2ms latency, which exceeds 1ms and therefore FAILS the sub-millisecond requirement. The correct answer that satisfies both requirements is C, not D. D should be eliminated because 1.2ms > 1ms violates the sub-millisecond latency constraint.
