Nokia Quality of Service Questions and Answers

Question 29

When deploying a Nokia MPLS network with QoS, how are the EXP bits set?

The first 3 bits of the DSCP value are copied directly into the EXP field on the first network egress.

The EXP bits are set on the first network egress, based on a combination of the SAP-ingress classification and the network policy applied.

The 3 priority bits are copied directly from the dot1p header into the EXP field of the first MPLS header.

The EXP bits are set based on a default map that translates DSCP codes into internal forwarding classes on SAP-ingress.

Question 30

What can be learned from the output of the command “show pools 1/2/2 network-egress” on the GigE port?

All incoming packets belonging to forwarding class “l2” are stored in the reserved buffer space.

All incoming packets belonging to forwarding class “af” are stored in the reserved buffer space.

All incoming packets belonging to forwarding class “l1” are stored in the reserved buffer space.

In-profile packets in the shared buffer space are being dropped.

Question 31

On a Nokia IOM 3, how is buffer memory allocated per forwarding complex?

512 MB ingress, 512 MB egress

256 MB ingress, 256 MB egress

1 GB dynamically allocated between ingress and egress.

768 MB dynamically allocated between ingress and egress.

768 MB, with a minimum of 256 MB ingress and egress, and an additional 256 MB dynamically allocated.

Question 32

Which of the following statements about CIR of a queue is TRUE?
