How does an IOM3 improve the queue usage over an IOM2 in a Nokia 7750 SR? (Choose two)

A. The IOM3 adds more memory to both forwarding complexes which increases the total number of queues available.

B. The IOM3 only contains a single forwarding complex which reduces the number of queues used.

C. The IOM3 allows multiple forwarding classes to be assigned to a single queue.

D. The IOM3 allows queues to be dynamically allocated between ingress and egress.

E. The IOM3 has a larger CPU capable of tracking active hardware queue utilization and adjusting memory allocation accordingly.

Which of the following statements about scheduling on the Nokia 7750 SR is FALSE?

A. When using priority-mode queues, traffic marked as low-priority on ingress and scheduled in the above-CIR loop will be considered as in-profile at egress.

B. When using priority-mode queues, traffic marked as high-priority on ingress and scheduled in the above-CIR loop will be considered as out-of-profile at egress.

C. When using profile-mode queues, traffic marked as low-priority on ingress and scheduled in the aboveCIR loop will be considered as out-of-profile at egress.

D. When using profile-mode queues, traffic marked as in-profile on ingress and scheduled in the above-CIR loop will still be considered as in-profile at egress.

Which of the following statements about a queue's rate parameters is FALSE?

A. If CIR = PIR, then all packets will be considered as in-profile.

B. CIR can be set to 0.

C. CIR can be larger than PIR.

D. CIR can be set to `max'.

Packets arrive at the VPLS SAP on PE1 with DSCP marking of af11 and Dot1p of 2. According to the QoS policies applied at routers PE1, P, and PE2, what is the DSCP value of packets egressing router PE2? (All the SDPs are MPLS- encapsulated, and all interfaces are using their default trust states).

A. af11

B. af21

C. af23

D. af31

Which of the following statements about the QoS treatment of self-generated traffic in the Nokia 7750 SR is FALSE?

A. All self-generated traffic is assigned into forwarding class NC by default.

B. Ingress self-generated traffic is stored in CPM queues and egress self-generated traffic is stored in IOM queues.

C. The self-generated packets will be marked with a default DSCP value.

D. The self-generated packets will be marked with default EXP bits.
