Which DSCP marking is represented as 101110 in an IP header?

The correct answer is A. EF. DSCP (Differentiated Services Code Point) values are 6-bit binary numbers embedded in the IP header. The binary value 101110 converts to decimal 46, which corresponds to the EF (Expedited Forwarding) DSCP marking. EF (DSCP 46) is used for the highest-priority traffic, typically…

Explanation

DSCP (Differentiated Services Code Point) values are 6-bit binary numbers embedded in the IP header. The binary value 101110 converts to decimal 46, which corresponds to the EF (Expedited Forwarding) DSCP marking. EF (DSCP 46) is used for the highest-priority traffic, typically voice bearer (RTP). For reference: CS3 = DSCP 24 = 011000; AF41 = DSCP 34 = 100010; AF31 = DSCP 26 = 011010. Memorizing that EF = 46 = 101110 is a fundamental QoS fact tested on Cisco collaboration exams.
