NS0-157 Question #53: Real Exam Question with Answer & Explanation

The correct answer is C: Flash Pool. Flash Pool enhances both read and write performance by combining SSDs and HDDs within the same aggregate, making it the correct choice for workloads requiring improved throughput in both directions.

Performance, Troubleshooting, and Security

Question

A customer wants the best performance for their Oracle DB solution. They are willing to configure their high-availability nodes so the load is less than 50% per node, to protect performance during failover. They want to enhance read and write performance. Which NetApp technology accomplishes this task?

Options

  • Adeduplication
  • Bthin provisioning
  • CFlash Pool
  • DFlashCache

Explanation

Flash Pool enhances both read and write performance by combining SSDs and HDDs within the same aggregate, making it the correct choice for workloads requiring improved throughput in both directions.

Common mistakes.

  • A. Deduplication reduces capacity consumption by eliminating redundant data blocks, but it does not directly enhance read or write I/O performance and can add CPU overhead.
  • B. Thin provisioning allocates storage on demand to save space, but it is a capacity management feature that provides no read or write performance improvement.
  • D. FlashCache (the PAM card) is a read-only cache module that accelerates read performance only; it does not cache writes, so it cannot satisfy the requirement to enhance both read and write performance.

Concept tested. Flash Pool hybrid aggregate read and write caching
