第22题:
a Frame Relay header includes a 1-bit discard eligible (DE) bit to provide the class of service (CoS)
an ATM header includes a 1-bit DE field to provide the CoS
an MPLS EXP field is inserted in the Layer 3 IP precedence field to identify the CoS
the CoS field only exists inside Ethernet frames when 802.1Q or Inter-Switch Link (ISL) trunking is used
in the IEEE 802.1p standard, three bits are used to identify the user priority bits for the CoS
in the IEEE 802.1q standard, six bits are used to identify the user priority bits for the CoS
