300-360 Question #75: Real Exam Question with Answer & Explanation

The correct answer is A: IP Camera. In a Cisco mesh network, when a wired device (such as an IP camera) is connected to the LAN port of a RAP (Root Access Point), the wired device itself is responsible for marking its own QoS DSCP values on upstream traffic before it enters the mesh network. The RAP trusts DSCP mar

Question

After implementing mesh with an IP surveillance camera connected to the LAN port on a RAP, the engineer notices that QoS is not being marked. In this setup, what device is responsible for marking upstream traffic from the camera?

Options

AIP Camera
BMAP
CRAP
DWireless Controller
EFirst-Hop Router

Explanation

In a Cisco mesh network, when a wired device (such as an IP camera) is connected to the LAN port of a RAP (Root Access Point), the wired device itself is responsible for marking its own QoS DSCP values on upstream traffic before it enters the mesh network. The RAP trusts DSCP markings from wired devices but does not re-mark traffic originating from those devices. The MAP (Mesh Access Point) is a wireless backhaul node and handles traffic forwarding but not origination QoS marking. The WLC (Wireless Controller) manages wireless QoS policies for wireless clients but does not mark traffic from wired devices attached to RAP LAN ports. The first-hop router is downstream from the RAP and not involved in marking traffic from the camera. Therefore, the IP camera must be configured to apply the appropriate DSCP markings.
