Cisco CCNA WLAN Architectures and Concepts Questions and Answers

Question 1

A network administrator is designing a wireless network for a large corporate campus with hundreds of access points.
The requirements include centralized management, seamless client roaming, and consistent policy enforcement.
Which WLAN architecture is BEST suited for this scenario?

Accepted Answer

Controller-based architecture

Answer

Ad-hoc mode

Answer

Autonomous AP architecture

Answer

Cloud-based architecture with each AP managed individually

Question 2

In a controller-based WLAN architecture using CAPWAP, what is the primary function of the 'Split-MAC' concept?

Accepted Answer

It divides the 802.11 MAC functions between the Lightweight Access Point (LAP) and the Wireless LAN Controller (WLC).

Answer

It allows a single AP to use multiple MAC addresses to serve different SSIDs.

Answer

It enables MAC filtering to be performed at either the AP or the switch, but not both.

Answer

It splits the wireless traffic into separate tunnels for data and voice.

Question 3

A company needs to deploy a wireless access point in a small, remote branch office with an unreliable WAN link to the central headquarters where the WLC is located. The goal is to allow wireless clients to continue accessing local resources even if the WAN link fails. Which AP mode should the administrator configure?

Accepted Answer

FlexConnect Mode

Answer

Local Mode

Answer

Monitor Mode

Answer

Sniffer Mode

Question 4

Which of the following correctly describes the CAPWAP tunnels established between a Lightweight Access Point (LAP) and a Wireless LAN Controller (WLC)?

Accepted Answer

Two separate UDP tunnels are used: a control tunnel on port 5246 and a data tunnel on port 5247.

Answer

A single encrypted TCP tunnel is used for both control and data traffic on port 5246.

Answer

Two separate UDP tunnels are used: a data tunnel on port 5246 and a control tunnel on port 5247.

Answer

A single unencrypted UDP tunnel is used for all traffic to maximize performance.

Question 5

A wireless client roams from an AP associated with WLC1 to an AP associated with WLC2. Both WLCs are in the same mobility group, but the client is assigned to a different VLAN/subnet after roaming. To maintain the client's session and IP address, what type of roaming occurs?

Accepted Answer

Layer 3 Inter-controller Roaming

Answer

Intra-controller Roaming

Answer

Layer 2 Inter-controller Roaming

Answer

Static Channel Roaming

Question 6

What is a primary characteristic of an autonomous WLAN architecture?

Accepted Answer

Each access point is individually configured and manages its own settings, security, and client associations.

Answer

It relies on a cloud-based dashboard for all configuration and firmware updates.

Answer

All client traffic is tunneled back to a central appliance using the CAPWAP protocol.

Answer

It requires a dedicated Wireless LAN Controller (WLC) on the local network.
