Question
What is a key advantage of PoE (Power over Ethernet)?
A. Reduces power consumption
B. Provides faster data transfer speeds
C. Allows network devices to receive power through Ethernet cables
D. Increases wireless network range
E. Improves network security
Answer
C. Allows network devices to receive power through Ethernet cables
Explanation
PoE enables devices like IP cameras and access points to receive power and data over a single Ethernet cable.
The key advantage of Power over Ethernet (PoE) is that it allows network devices to receive power through Ethernet cables.
PoE technology enables devices such as IP cameras, wireless access points, and VoIP phones to receive both electrical power and data over a single Ethernet cable, eliminating the need for separate power supplies or electrical outlets near each device.
This integration simplifies installation, reduces cabling and labor costs, and provides greater flexibility in device placement since devices are no longer limited by the location of power outlets.
PoE also supports centralized power management, making it easier to monitor and control power delivery to network devices.
By streamlining infrastructure and supporting both data and power transmission in one cable, PoE is especially valuable for modern networks, IoT deployments, and environments where ease of installation and flexibility are priorities.
PoE enables devices to receive both power and data over a single cable, simplifying network design and installation while reducing costs and increasing flexibility.
