Wait, the PDCP layer? I was sure it was the RLC layer. Dang, I really need to stop guessing and start studying harder for these exams.

Hmm, the PDCP layer, huh? I was totally off with my guess of the MAC layer. Guess I need to brush up on my LTE knowledge.

I thought the PHY layer was responsible for all the physical-layer stuff, but I guess the PDCP layer handles the security stuff. Interesting!

I’m leaning towards PDCP as well, but I wish I had reviewed the specifics of each layer more thoroughly.

I remember practicing a similar question, and I think RLC was more about reliability, not encryption.

I think the answer might be PDCP since it handles encryption, but I'm not completely sure.

I'm a bit confused on the differences between the layers. Maybe I should review my notes on the LTE air interface before answering this.
