QUESTION 237

An access-layer Cisco Catalyst 3550 is configured with voice and data VLANs. All QoS settings remain the factory default settings, with two exceptions.

1.         1.”mls qos trust device cisco-phone” is applied to all access-edge ports

2.         “mls qos trust dscp” is applied to all uplink-ports

A.      Voice: CoS 5 and DSCP 40

Call-Signaling: CoS 3 and DSCP 24

Data: CoS 0 and DSCP 0

 

B.      Voice: CoS 5 and DSCP 46

Call-Signaling: CoS 3 and DSCP 24

Data: CoS 0 and DSCP 0

 

C.      Voice: CoS 5 and DSCP 40

Call-Signaling: CoS 3 and DSCP 26

Data: CoS 0 and DSCP 0

 

D.      Voice: CoS 5 and DSCP 40

Call-Signaling: CoS 3 and DSCP 24
