CompTIA Cloud+ (CV0-002) — Question 7

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?

Answer options

• A. Compression 1:1 Deduplication 4:1 Overall savings 4:1 Average latency 1.0ms
• B. Compression 1.5:1 Deduplication 1.8:1 Overall savings 2.2:1 Average latency 600us
• C. Compression 1.3:1 Deduplication 3.1:1 Overall savings 4.3:1 Average latency 900us
• D. Compression 1.8:1 Deduplication 2.7:1 Overall savings 4.2:1 Average latency 1.2ms

Correct answer: A

Explanation

Answer A is correct because it achieves the desired 4:1 overall storage savings while maintaining an average latency of 1.0ms, which is within the sub-millisecond requirement. The other options do not meet both the required storage efficiency or have higher latencies than allowed, making them unsuitable for the specified goals.
