An administrator notices that a file server is filling up quickly but has many of the same files in different directories. Which of the following storage management techniques would resolve this…

Provisioning refers to the allocation of storage resources, either thin or thick, but does not inherently reduce the amount of data stored.

Encryption secures data by transforming it into an unreadable format, but it does not reduce the storage space consumed by duplicate files.

Deduplication is a data compression technique that eliminates redundant copies of data. It works by identifying identical blocks or files and storing only a single copy, replacing subsequent duplicates with pointers to the original, thereby saving significant storage space, which directly addresses the issue of many identical files.

Partitioning divides a physical disk into logical sections, which helps in organizing data and managing file systems, but it does not reduce the overall amount of data stored or eliminate duplicates.
