ZIP is for files, not images! DCT is the way to go.

I heard it’s not just DCT, but that’s the main part.

TIFF-8 doesn’t sound right for JPEG compression, but I’m a bit confused about the other options.

I feel like I’ve seen DCT mentioned in practice questions before, but I can’t recall if it’s the right answer here.

I remember studying compression techniques, but I’m not sure if it was DCT or something else like ZIP.

I think JPEG uses some kind of transformation for compression, maybe DCT? That sounds familiar.

Okay, I've got this. JPEG uses discrete cosine transform (DCT) to compress image data by transforming the pixel information into frequency domain. I'm confident that's the right answer.

Wait, is it not ZIP? I thought JPEG used a similar compression algorithm to ZIP files. I'll have to think this through more carefully.

DCT, that's the one! I remember learning about how JPEG uses discrete cosine transform to compress image data. Definitely going with that option.

I think the key here is understanding how routing protocols like OSPF and EIGRP determine the best path. Metrics and administrative distance would be my top picks.
