Dell EMC Associate – Information Storage and Management v4 — Question 65

Which data deduplication method increases the probability of identifying duplicate data even when there is only a minor difference between two documents?

Answer options

• A. Variable-length segment
• B. Single-instance
• C. File-level
• D. Object-level

Correct answer: A

Explanation

The correct answer is A, Variable-length segment, because it allows for more granular comparison of data segments, making it easier to detect duplicates with minor differences. The other methods, such as Single-instance, File-level, and Object-level, may not capture subtle variations as effectively due to their broader focus on entire files or objects.
