Question # 137

All interfaces are using their default trust states and MPLS is used as the transport tunnel. The SAP-ingress, SAP-egress, and network QoS policies have been configured as shown below. Assume that the default network-queue policy is used on each router.

At router PE 1, customer traffic is arriving marked with DSCP BE and tagged with a dot1p value of 3.

Based on the configuration shown below for the VPRN service, what will be the DSCP and dot1p marking for the packet egressing at router PE 2? (Choose two)

Options:

The DSCP value will be set to af21.

The DSCP value will be set to be.

TheDSCPvaluewillbesettoaf23.

The DSCP value will be set to af 12.

Thedot1pvaluewillbesetto5.

Only one interface on the CE is required for both VPN and Internet connectivity.

The Nokia 7750 SR supports route leaking in full mesh and extranet VPRN topologies only.
