During a private cloud migration, to reduce storage utilization for a file server with many duplicates and compressed audio files, which storage technology is MOST likely to help?

• A. Compression
• B. Thin provisioning
• C. Deduplication
• D. Tokenization

Answer: (C)

Deduplication removes redundant data across the stored data. It identifies identical blocks or chunks that appear in multiple files and stores only one copy, with references from the other locations to that single copy. In a private cloud migration where a file server has many duplicates and a lot of compressed audio, deduplication can massively cut the physical storage needed because the same data (the duplicates) is saved only once, no matter how many files reference it. Compression helps reduce size within individual files, but it doesn’t automatically consolidate identical blocks across different files. Thin provisioning and tokenization don’t reduce the actual amount of stored data—the former delays space allocation, and the latter replaces data with tokens for security. So deduplication is the most effective choice for reducing storage utilization in this scenario.
