Wait, can you really use readinto with a bytearray like that?

I definitely recall using readinto before, so I think A and C could be the best choices here.

I’m a bit confused about option D; it seems like it could work, but I’m not sure if it matches the question exactly.

I think option A looks familiar, but I'm not sure if it's the right way to initialize the bytearray.

I'm a little confused by this question. The options seem to cover a range of different machine learning techniques, but I'm not sure which one is best for anomaly detection. I'll have to review my notes and try to figure this out.

I've seen a practice question that mentioned HDX Insight specifically in relation to optimization techniques. That's where I'm leaning.
