200-301 Question 237
Select 3A network engineer is tasked with setting up a WLAN and is connecting several Access Points (APs) to a Wireless LAN Controller (WLC). The APs are configured to operate in lightweight mode. Which of the following physical infrastructure connections are required to ensure proper communication between the APs and the WLC?
- A
The APs must be connected to a switch that supports VLANs.
- B
The WLC must be connected to the same Layer 3 network as the APs.
- C
Each AP requires a unique SSID broadcast to connect to the WLC.
- D
The APs must be powered through either a Power over Ethernet (PoE) source or a separate power supply.
- E
The WLC must be directly connected to each AP through a dedicated Ethernet cable.
Show answer and explanation
Correct answers: A, B, D
Explanation
To establish physical infrastructure connections for lightweight APs, a switch that supports VLANs and Layer 3 connectivity between the APs and the WLC is necessary. Additionally, APs require a power source, such as PoE or a separate power supply. SSIDs and direct connections between APs and the WLC are not prerequisites for this setup.
- A. Correct.
Correct: APs typically connect to a switch that supports VLANs, allowing traffic to be appropriately tagged and managed.
- B. Correct.
Correct: For lightweight APs to register with the WLC, they must be on the same Layer 3 network or reachable via routing.
- C. Incorrect.
Incorrect: SSIDs are used to identify wireless networks for end devices, but they are not required for APs to connect to the WLC.
- D. Correct.
Correct: APs need power to function, which can be provided via PoE or a separate power source.
- E. Incorrect.
Incorrect: Direct Ethernet connections between each AP and the WLC are not required. APs connect to the WLC using the network infrastructure (e.g., switches).
