CWNA: Certified Wireless Network Administrator v107 — Question 53

When implementing PoE, what role is played by a switch?

Answer options

• A. PD
• B. PSE
• C. Midspan injector
• D. Power splitter

Correct answer: D

Explanation

The correct answer is D, as a power splitter divides the power received over Ethernet into separate streams for powered devices. Options A (PD) and B (PSE) refer to powered devices and power sourcing equipment, respectively, and do not describe the role of a switch. Option C, a Midspan injector, is used to add power to an Ethernet cable but is not the switch itself.
