Target for data-at-rest encryption, ranging from more granular (file or row/record) to less granular (volume/partition/disk or database), is known as?

• A. Encryption Levels
• B. Data In Transit
• C. True Random Number Generator (TRNG)
• D. Trusted Platform Module (TPM)

Answer: (A)

The concept here is the level of granularity at which data at rest can be encrypted. Encryption levels describe how finely you apply encryption, ranging from very granular targets like individual files or database rows to coarser targets such as entire volumes, partitions, disks, or the whole database. This spectrum helps determine how much data is protected at once and how easily access-controlled encryption can be managed. The other terms don’t describe this target scope: data in transit refers to encryption of data while it’s moving, not stored; a True Random Number Generator is about producing unpredictable numbers for cryptographic use; and a Trusted Platform Module is a hardware component that stores keys and performs secure operations, not the concept of how finely data at rest is encrypted.
