Which option is the default Cisco Wireless Unified Communications endpoints marking for video media traffic or video RTP traffic? 

Answer options:

A. DSCP 8
B. DSCP 24
C. DSCP 34
D. DSCP 46

C

When configuring network-level quality of service (QoS), Cisco video endpoints (including Cisco Unified IP Phone 8900 and 9900 Series and Cisco TelePresence System EX Series devices) generally mark traffic at Layer 3 according to Cisco general QoS guidelines related to voice and video packet marking (video media as DSCP 34 or PHB AF41; call signaling as DSCP 24 or PHB CS3) and therefore these devices can be trusted.
