200-301 Question 235
Select 3A network administrator is setting up a new wireless network. The Access Points (APs) will connect to a Wireless LAN Controller (WLC) for centralized management. To ensure proper physical connectivity, which of the following infrastructure connections are required?
- A
APs are connected to a switch using Ethernet cables.
- B
WLC is connected to the network core switch using Ethernet.
- C
APs are directly connected to the WLC using a console cable.
- D
APs require a Power over Ethernet (PoE) enabled switch for power supply.
- E
WLC requires a wireless connection to communicate with APs.
Show answer and explanation
Correct answers: A, B, D
Explanation
To ensure proper physical infrastructure connections, APs must connect to a switch using Ethernet. The switch provides network connectivity and, in many cases, Power over Ethernet (PoE) to power the APs. The WLC connects to the network core switch using Ethernet to manage the APs and the wireless network effectively. Direct console connections or wireless connections between APs and the WLC are not part of standard WLAN infrastructure designs.
- A. Correct.
Correct: APs are typically connected to a switch using Ethernet cables to allow data transmission to the network and the WLC.
- B. Correct.
Correct: The WLC must be connected to the network core switch using Ethernet to manage the APs and the WLAN.
- C. Incorrect.
Incorrect: APs are not directly connected to the WLC using a console cable. They communicate with the WLC over the Ethernet network.
- D. Correct.
Correct: APs commonly use Power over Ethernet (PoE) to receive both power and data over a single Ethernet cable.
- E. Incorrect.
Incorrect: The WLC uses wired connectivity to communicate with APs, not a wireless connection.
