You captured the wireless frame shown in the exhibit during a post-deployment verification site survey.
What can you tell the customer about this network?

A.
This is a video stream packet, and there is a QoS marking issue on the wired side, because the DSCP
value should not be set to 0.

B.
This is a voice control packet, and the configuration looks normal, as voice control may or may not have
a DSCP tag.

C.
This is a video stream packet, and the configuration looks normal, as DSCP is always set to 0 when
802.11e QoS is specified at Layer 2.

D.
This is a voice RTP packet, and its marking was downgraded from Voice to Video which is a sign of
congestion issues.
