12? Seems low for a 90 W budget.

Wait, are you sure? I thought it was 13.

Class 2 devices use 7 W each, so that's 12 devices.

I feel like 14 sounds too high; I might lean towards 12 or 13 based on what I studied.

I practiced a similar question, and I think it was around 12 devices, but I can't remember the exact math.

I remember something about needing to account for overhead, but I'm not sure how much that is for PoE switches.

I think class 2 devices use about 7 watts each, so maybe we can divide 90 by that?

Alright, let me double-check my work. Yep, I agree with Emily - the answer is 12 class 2 devices that can be powered by the 90 W PoE switch.

Wait, I'm not sure about this. Shouldn't we round up to the nearest whole number? I think the answer might be 13 devices.

I've got this! The answer is 12 class 2 devices. It's just a simple division problem - 90 W / 7 W per device = 12.8, which rounds down to 12.

Hmm, I'm a bit confused. Do we need to account for any overhead or efficiency factors? I want to make sure I'm not missing anything.

Okay, let's think this through step-by-step. The power budget is 90 W, and class 2 devices have a max power of 7 W each. So we just need to divide the total power by the power per device.

This is a good question to test our understanding of marketing technology. I'll review the key features of Marketo and ESPs, and then match those up with the answer choices to identify the best response.

Hmm, I'm a bit unsure about the difference between "Zoom to selection" and "Zoom-out". I'll need to think through those options carefully to make sure I understand the distinction.

Whoa, hold up! Did someone say 'class 2 devices'? I thought this was a PoE switch, not a high school dance! *chuckles* Anyway, A looks legit.

Okay, let's think this through. 90W budget, class 2 devices at 7W each... Yep, A is the way to go. Easy peasy lemon squeezy!

Yep, that's correct. Class 2 devices consume 7W each, so 90W budget can power 12 of them.

Hmm, seems like a straightforward power budget calculation. Let's see, class 2 devices have a max power of 7W, so 90W / 7W per device would give us 12 devices. I'm going with A.
