Questions and Answers

Why is it necessary to trunk wired VLANs from the distribution layer to the access layer switches in a network with autonomous APs?

To simplify the configuration of SSIDs on the autonomous APs.
To forward traffic between the wireless LANs and the wired VLANs where routing decisions are made. (correct)
To reduce the number of IP addresses needed for the wireless network.
To ensure that each autonomous AP can be managed directly without VLANs.

What purpose does a dedicated management VLAN serve in a network utilizing autonomous APs?

It carries all user data traffic, improving network performance.
It provides a separate channel for remote management of the APs, isolated from the data VLANs. (correct)
It automatically configures the transmit power of the APs.
It simplifies the process of assigning IP addresses to wireless clients.

What is a potential drawback of using autonomous APs as a network scales?

Autonomous APs require specialized hardware, reducing hardware choices for the network.
The increasing overhead of managing each AP individually and ensuring VLAN reachability can become cumbersome. (correct)
Autonomous APs do not support multiple SSIDs so deploying multiple SSIDs will result in multiple APs.
Autonomous APs offer lower security compared to controller-based APs.

Flashcards

Autonomous APs

Operate independently, each providing one or more fully functional, standalone basic service sets (BSSs).

Autonomous APs

Self-sufficient and standalone access points that are a natural extension of a switched network, connecting wireless SSIDs to wired VLANs.

Lightweight APs

Cisco access points that require a wireless LAN controller (WLC) to operate.

Trunked VLANs

The wired VLANs must be configured to extend from the distribution layer, where routing occurs, down to the access layer switches where the VLANs connect to each AP.
