B . Patch panel and access point can receive but don't provide electricity, pretty sure that's the trap here.
B . Only the PoE switch actually sends power out to devices over the network cable.
Option B. Only the PoE switch actually powers devices by sending electricity down the Ethernet cable.

B tbh, unless you're talking about devices that actually receive the power, not supply it.
Option B makes the most sense. Only a PoE switch actually provides power through the Ethernet cable to devices like access points or VoIP phones, while others just receive or pass data. Saw similar wording in practice exams and it always pointed to PoE switches for supplying electricity. Pretty sure that’s right, but open if anyone disagrees.
B is it. Only a PoE switch actually sends power down the cable, not just data. You’ll see this in the official objectives and plenty of practice tests. I think that’s the best answer here but open to feedback.
B for sure. Only a PoE switch injects power onto the network cable so powered devices like IP cameras or VoIP phones can run without separate adapters. Access points and patch panels get power, but don’t supply it to downstream devices. Pretty confident here but let me know if I’m missing something.
A patch panel or access point won't power anything, so it's B. This kind of thing shows up in the official guide and practice exams, pretty sure.
Not totally sure but I think it’s C. Don’t PoE access points send power out too? Can someone confirm?
Be respectful. No spam.
