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

  • A. DSCP 8
  • B. DSCP 24
  • C. DSCP 34
  • D. DSCP 46
Answer: Option C.
Explanation: 

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.
