Which of the following statements are TRUE when discussing self-generated traffic QoS? (Choose two)

A.

In order to mark Layer 2 traffic, sgt-qos will set various ToS bits.

B.

DSCP bits can be set per application, per routing instance.

C.

The DSCP marking stays nc1 for all applications. Only the internal FC is manipulated across different applications.

D.

In order to mark Layer 2 self-generated traffic, network interfaces must be set to dot1Q.

E.

The internal forwarding class for self-generated traffic is set once and applied to the base router and all VPRN instances.

Which priority-mode queue parameter may influence both the profile marking, and scheduling priority of a queue?

A.

PIR

B.

CIR

C.

MBS

D.

burst-limit

For the Inter-AS model A VPRN, which of the following is TRUE when CE2 sends an IP packet to 192.168.1. J?

A.

PE2 pushes one label on the IP packet and label-switches it to ASBR2.

B.

ASBR2 forwards an unlabeled IP packet to ASBR1.

C.

ASBR1 pushes one label on the IP packet and label-switches it to PEL

D.

PE1 pops one label and forwards the IP packet to CE1.
