Question

Difficulty: MediumNetwork Hardware Devices

A network technician is tasked with deploying an outdoor Wireless Access Point (WAP) located 250 meters (820 feet) away from the main telecommunications closet. The WAP requires Power over Ethernet (PoE) to function, but standard copper Ethernet cables have a maximum distance limitation of 100 meters. Which TWO of the following hardware devices should the technician install to establish connectivity and supply power to the remote WAP? (Select TWO.)

  1. Fiber media convertersAnswer
  2. PoE injectorAnswer
  3. C
    Unmanaged Layer 2 switch
  4. D
    DHCP server

Answer

The technician should install fiber media converters to span the 250-meter distance over fiber optic cabling and a PoE injector to supply electrical power over the final copper patch cable to the access point.
Fiber media converters allow data transmission to bypass the 100-meter copper restriction by utilizing fiber optic cable across the 250-meter span. A PoE injector injects necessary electrical power into the final copper Ethernet patch cable to operate the wireless access point.

Step-by-Step Solution

1
Identify physical media distance constraints
Standard Category 6 Ethernet cabling is limited to 100 meters (328 feet). Reaching 250 meters requires fiber optic cable.
Media converters are necessary at each end of the fiber run to bridge the copper switch port to the fiber line and back to copper at the remote end.
2
Determine power delivery method
The access point requires Power over Ethernet (PoE), but optical fiber cannot transport electrical current.
A PoE injector must be installed on the short copper patch cord between the receiving media converter and the WAP to add inline power.

Key Concept

Utilizing media converters for distance extension and PoE injectors for inline power delivery.
