Huawei Certified ICT Professional – Storage (HCIP-Storage) — Question 22

An enterprise has deployed multiple applications, such as desktop cloud, database, video on demand (VoD), and backup. These applications occupy a large amount of storage resources. The enterprise plans to use the deduplication and compression features. Which of the following configurations are recommended?

Answer options

• A. Deduplication and compression are not recommended for VOD scenarios because video files have been compressed by application software and re-compression will be inefficient.
• B. Deduplication is recommended for desktop cloud scenarios because there is a large amount of duplicate data among multiple virtual images.
• C. Compression is recommended for database-scenarios because a large amount of data needs to be stored.
• D. Deduplication is not recommended for backup scenarios because all backup data must be retained.

Correct answer: C

Explanation

The correct answer is C because databases often contain large amounts of redundant data that can benefit significantly from compression, thus saving storage space. Option A is incorrect as video files are typically already compressed, rendering further compression ineffective. Option B, while true, does not pertain to compression, which is the focus of the question. Option D is also wrong because deduplication is indeed useful for backup scenarios, even if data retention is necessary.
