Question 7
Customer requirements and a WLAN site survey require a Cisco 1250 AP operating at full
802.11a/b/g/n located approximately 150 meters from the closest IDF. What is the best solution to provide wireless coverage to this portion of the customer's facility?
- A. At the AP location, install a power drop and a Cisco Aironet Power Injector Media Converter (AIR-PWRINJ-1000AF) to power and the Cisco 1250 and extend the Cat 5 link.
- B. Install an external Cisco Mid-Span 802.3af power injection panel in the same rack as the access switch to extend the driven distance of the structured cable plant.
- C. At the AP location, install a power drop and a Cisco Aironet Power Injector Media Converter (AIR-PWRINJ-FIB) for the Cisco 1250. Then connect a Cat 5 cable from the AP to a fiber-optic-to-copper transceiver which connects to a fiber link to the IDF. At the access switch, connect the fiber cable from the AP location to a fiber-optic port on the switch.
- D. At the AP location, install a power drop and a Cisco AIR-PWRINJ4 power adapter for the Cisco 1250. Connect the Cat 5 cable to the AP from the IDF.
- E. At the AP location, install a local power drop and local power supply for the Cisco 1250. Connect the AP through a pair of fiber-optic-to-copper transceivers back to the access layer switch to provide data access.
Answer : E
