Question 1

Which of the following statements describes an advantage of the DiffServ QoS model over the IntServ QoS

model?

A : DiffServ reserves resources dynamically using the RSVP protocol.

B : DiffServ only requires packets to be classified into forwarding classes at the first network hop.

C : DiffServ provides granular differentiation and superior fairness because it processes traffic streams individually.

D : DiffServ is more scalable it treats traffic streams as aggregates.

Answer: D

Question 2

If packets egressing a SAP do not match any criteria defined in the SAP-egress policy, which forwarding class

will these packets be assigned to?

A : The default forwarding class defined in the SAP-egress policy.

B : The forwarding class inherited from network ingress classification.

C : Best Effort.

D : If there is no match, packets will be dropped.

Answer: A

Question 3

E : An SLA is a standard set of network QoS policies that a provider shares to all its customers, allowing them to better understand the treatment of traffic within the provider-s network.

Answer: B,D

Question 4

What feature makes a traffic stream real-time?

A : Its rate fluctuates rapidly with time.

B : Its bandwidth requirements are high.

C : Time between packets remains unchanged and end-to-end delay is kept to a minimum.

D : All packets received are guaranteed to be delivered to the destination.

Answer: C

Question 5

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.
