200-301 Question 234
Select 3A network administrator is deploying a new wireless network using lightweight access points (APs) and a Wireless LAN Controller (WLC). The APs need to be connected to the WLC for centralized management. Which of the following physical infrastructure connections are required to ensure proper communication between the APs and the WLC?
- A
APs must be connected to a switch that has Layer 2 connectivity to the WLC.
- B
APs must be directly connected to the WLC via Ethernet cables.
- C
The switch connecting the APs must support Power over Ethernet (PoE) to power the APs.
- D
The WLC must be connected to the network core or distribution layer switch.
- E
A dedicated wireless link is required between the APs and the WLC.
Show answer and explanation
Correct answers: A, C, D
Explanation
To enable communication between lightweight APs and the WLC, the APs must be connected to a switch that has Layer 2 or Layer 3 connectivity to the WLC. The switches connecting the APs should support PoE to power the APs. Additionally, the WLC should be connected to a core or distribution layer switch to facilitate efficient traffic routing. Direct physical connections or dedicated wireless links between APs and the WLC are not required in typical deployments.
- A. Correct.
Correct: APs are typically connected to access layer switches, which in turn need Layer 2 or Layer 3 connectivity to the WLC for control and data traffic.
- B. Incorrect.
Incorrect: Lightweight APs do not require direct physical connections to the WLC; they communicate through the network infrastructure.
- C. Correct.
Correct: Power over Ethernet (PoE) support is usually required to power lightweight APs without needing separate power adapters.
- D. Correct.
Correct: The WLC is typically connected to the core or distribution layer to ensure proper routing of control and data traffic between APs and other network devices.
- E. Incorrect.
Incorrect: No dedicated wireless link is required between the APs and the WLC, as communication happens over the wired network.
