Question

An access-layer Cisco Catalyst 3550 is configured with voice and data VLANs. All QoS settings Cisco 350-030 Exam have been left at factory defaults, with two exceptions only:

Some access-edge ports are connected to Cisco IP Phones and other ports are directly connected to PCs. Assume that malicious users are setting the CoS and DSCP values of all their PC- generated packets to CoS 6 and EF, respectively. Assume that the IP Phones are administered by Cisco CallManager 4.0 (or higher). What will be the DSCP settings of the (IP Phone-generated) Voice and Call-Signaling packets, as well as the (PC-generated) data packets as these packets exit the switch en route to the distribution layer?
