A university is deploying a WLAN for a new research building. The building will have three types of users: researchers who need high-priority access to a research database, students who need general internet access, and guests who should have only basic internet access. The network team wants to use a single WLAN but needs to differentiate traffic based on user role. Which approach will best meet this requirement?

Use a single WLAN and rely on the client devices to mark their own traffic

Create three separate WLANs, one for each user group, and apply different QoS policies

Use a single WLAN with a QoS policy that prioritizes all traffic equally

Use a single WLAN and configure the WLC to prioritize based on MAC addresses

In a Cisco wireless network, how are wired QoS markings such as DSCP or CoS typically handled when a frame is received by the wireless LAN controller (WLC) and forwarded to a wireless client?

The WLC maps the wired marking to an 802.11 User Priority (UP) and WMM access category for the wireless transmission.

The WLC relies on the access point to map the wired CoS value to the wireless priority.

The WLC preserves the DSCP value unchanged and uses it directly as the 802.11 User Priority.

The WLC strips all QoS markings and transmits the frame with best-effort priority.
