Answer: a) N² files. b) 2N files.
Explanation:
if an user can choose freeely both the video and the audio quality, if they are stored separately, but the user can download any mix of them as a single file, the server must store one audio version for each video version, so it will need to store NxN = N² files.
If, instead, the server can send the audio and video streams separately, so the user can choose one of the N video available, and one of the N audio versions, the server will need to store only N video files + N audio audio files, i.e. , 2 N files.
