Which term represents the granularity levels used for encrypting data at rest, from file-level to database-level?

• A. Data In Motion
• B. Data At Rest
• C. True Random Number Generator (TRNG)
• D. Encryption Levels

Answer: (D)

Protecting data at rest can be applied at different scopes, from individual files up to entire databases. This describes the encryption levels—the different granularities at which you can apply encryption. You might encrypt a single file, a group of files, a database as a whole, or even specific columns within a database. That range of scopes is what “encryption levels” captures. This concept differs from data in motion (protecting data as it’s transmitted), data at rest in general (the state of stored data), and a random number generator (a cryptographic primitive used to create randomness). Understanding encryption levels helps you design the right balance of security and performance based on how finely you want to control encryption.
