Exam 200-301 topic 1 question 28 discussion

A, B, and C all are connection related. D is the only answer that relates to "communication"

the correct answer is option D: "The access point has the ability to link to any switch in the network, assuming connectivity to the WLC." The AP can be connected to any switch in the network, as long as the switch has connectivity to the WLC. The AP and the WLC exchange CAPWAP messages over IP, using UDP port 5246 or 5247, depending on whether the messages are encrypted.

D. The access point has the ability to link to any switch in the network, assuming connectivity to the WLC. Option A is incorrect because the access point needs to be connected to the wired network to establish CAPWAP communication with the WLC. Option B is incorrect because the access point doesn't necessarily have to be connected to the same switch as the WLC. It can be connected to any switch within the network infrastructure, as long as there is connectivity between the access point and the WLC. Option C is incorrect because the access point does not typically require a direct copper cable connection to the WLC. The communication between the access point and the WLC is achieved through the existing network infrastructure, not through a direct point-to-point connection. Therefore, option D is the correct answer. The access point has the flexibility to link to any switch in the network, as long as there is connectivity to the WLC, allowing for CAPWAP communication between the access point and the WLC.

D is correct

"B" seems correct. For option "D" on the other hand, access point does not have the ability to link to any switch in the network assuming connectivity to the WLC. CAPWAP communication between an access point in local mode and a WLC typically occurs over the wired network infrastructure using the CAPWAP protocol. The access point must be able to reach the WLC's IP address, which can be configured statically or obtained dynamically through DHCP. The access point and WLC must be on the same IP subnet or have Layer 3 connectivity between their subnets.

Ref: Understanding Local Switching on Access Points - TechLibrary - Juniper Networks “… How Does Local Switching Work? When local switching is enabled on an access point, control traffic is managed by a controller and data traffic is handled by the local switches using CAPWAP. …” A. The access point must not be connected to the wired network, as it would create a loop Wrong answer. B. The access point must be connected to the same switch as the WLC Wrong answer. C. The access point must directly connect to the WLC using a copper cable Wrong answer. D. The access point has the ability to link to any switch in the network, assuming connectivity to the WLC Correct answer.

D is most correct and is the general case.

Cisco AP Modes. ■ Local: The default lightweight mode that offers one or more functioning BSSs on a specific channel. During times that it is not transmitting, the AP will scan the other channels to measure the level of noise, measure interference, discover rogue devices, and match against intrusion detection system (IDS) events. ■ FlexConnect: An AP at a remote site can locally switch traffic between an SSID and a VLAN if its CAPWAP tunnel to the WLC is down and if it is configured to do so. I think this question should be asking the FlexConnect mode not the Local mode. In this sense, D is not really right but the other options are totally wrong.

CAPWAP doesnt communicate, the communcation is called CAPWAP. its a tunnel from the core layer that terminates on the access layer.

This is split-Mac address topic

Answer D seems to be best answer here the Control And Provisioning of Wireless Access Points is a point to point tunnel between the AP's you deploy out in the office space and the central WLC device sitting in your datacentre

Is this topic relevant in the CCNA? No where can I find CAPWAP (in detail) in the CCNA study material. Unless if this is new material added to the CCNA.

not found direct reference to support answer D, but reference to reject B, see the topology of, which has one layer-2 and one layer-3 switches between WLC and AP

i need the reference for capwap
