200-301 Question 236
Select 3A network administrator is setting up a WLAN for an office and needs to establish the physical connections between the Access Points (APs) and the Wireless LAN Controller (WLC). Which of the following connections are required to ensure proper functionality of the WLAN components?
- A
Each AP should be connected to a PoE-enabled switch port.
- B
The WLC should be connected to the network core switch.
- C
APs must be directly connected to the WLC using Ethernet cables.
- D
The WLC must have a Layer 3 interface configured for communication with APs.
- E
Each AP must be connected to the WLC using a serial connection.
Show answer and explanation
Correct answers: A, B, D
Explanation
To ensure proper functionality of WLAN components, Access Points (APs) require a Power over Ethernet (PoE) connection to provide both power and network access. The WLC must be integrated into the network by connecting it to the core switch, and Layer 3 communication must be configured between the WLC and APs. Direct Ethernet or serial connections between the APs and WLC are not required, as communication occurs over the existing network infrastructure.
- A. Correct.
Correct: APs typically require a PoE-enabled switch port to power them and to provide network connectivity.
- B. Correct.
Correct: The WLC should be connected to the core switch of the network to manage and communicate with the APs effectively.
- C. Incorrect.
Incorrect: APs do not need to be directly connected to the WLC; they communicate with the WLC over the network, typically using Layer 3 protocols.
- D. Correct.
Correct: The WLC must have a Layer 3 interface configured to enable communication with the APs over the network.
- E. Incorrect.
Incorrect: Serial connections are not used to connect APs to the WLC. Communication is done over Ethernet and IP-based networks.
