Implementing Cisco Enterprise Wireless Networks (ENWLSI) — Question 270

A network engineer wants to implement QoS across the network that supports multiple VLANs. All the APs are connected to switch ports and are configured in local mode. Which trust model must be configured on the switch ports to which the APs are connected?

Answer options

• A. CoS
• B. WMM UP
• C. DSCP
• D. IPP

Correct answer: C

Explanation

The correct answer is DSCP, as it is the model used for differentiating service levels in IP networks. CoS, WMM UP, and IPP are not suitable for managing QoS across multiple VLANs in this context, as they do not provide the same level of granularity and compatibility with IP traffic as DSCP does.
