I've heard that some EX Series switches do support up to 30 W, but for IEEE 802.3af it's 15.4 W.

I think you might be mistaken. The IEEE 802.3af standard definitely allows for more power allocation.

Okay, let's think this through. The question says we're using EX Series switches, which I believe support the 802.3af standard. So the answer has to be 15.4W, right?

Wait, wait, wait... I thought 802.3af was 30W? Or is that the newer 802.3at standard? Ugh, I need to brush up on my PoE knowledge.

Definitely, this is a pretty basic PoE question. I'm just hoping there aren't any tricky parts that'll catch us off guard.

Wow, this question is pretty straightforward, don't you think? The 802.3af standard is pretty well-known, so I'm sure we all know the answer to this one.
