Exam CAS-004 topic 1 question 103 discussion

"in use" = processed in the memory "at rest" = stored in drives etc "in transit" = as data moves across media

Key words are "in use". Answer should be memory.

This option correctly identifies the context of "data in use" and how cryptographic solutions can be applied to protect it during active processing

Data in use is always in volatile memory, whether that is VRAM on the file system or within the RAM.

Data in use is data that is currently being updated, processed, erased, accessed or read by a system. This type of data is not being passively stored, but is instead actively moving through parts of an IT infrastructure. https://www.techtarget.com/whatis/definition/data-in-use

If the data is being passed across a local network, would that not mean that it is "in use". It wouldn't pass if it were not being accessed. I could be wrong, but that is my thinking.
