A Customer with a Dedicated Frame Relay Network Is Planning

Multiple Choice

A customer with a dedicated Frame Relay network is planning to move its circuits onto a service provider MPLS network. Instead of moving to Ethernet access links right away, the customer wants to tunnel the Frame Relay information across the MPLS network using AToM pseudowire. How is QoS information transmitted across an AToM pseudowire?

A) QoS information is translated into the MPLS EXP bits in the MPLS header
B) QoS information is carried in a control word that is attached to the MPLS frame
C) QoS information is preserved in the Frame Relay header and encapsulated into the pseudowire frame
D) QoS information cannot be transported through a pseudowire and is dropped
