Question 148

(0)

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

Question 149

(0)

Which of the following is NOT an adaptation rule supported on the Nokia 7750 SR for calculating the operational CIR/PIR of a queue?

Question 150

(0)

Which of the following statements about burst-limit of a queue is FALSE?

Question 141

Which of the following statements about buffer admission control techniques is FALSE?

A packet is accepted into a queue based on its priority and forwarding class.

Buffer admission control limits the number of out-of-profile packets that enter the queue.

Both high priority-only buffer space and WRED can be used in a queue.

Priority is used when a packet enters a SAP-ingress queue.

Question 142

Which of the following is NOT a reason for configuring a slope policy on a queue?

To have control over the amount of the low priority packets that enter the queue.

To control any traffic flowing through the shared buffer space of the queue.

To limit the number of the TCP sessions that go into slow start during congestion.

To force the TCP algorithm to increase its transmission window upon detecting a congestion.

A profile-mode queue is configured with MBS = 100 KB, CBS = 50 KB and High-Priority-Only = 40%. Assume there is no CBS overbooking, and the slope-policy is disabled. If the current queue depth is 70 KB, what will happen to an out-of-profile packet when it is transmitted to the queue?

It will be stored in the reserved buffer space and remain out-of-profile.

It will be stored in the reserved buffer space and become in-profile.

It will contend for shared buffer space with packets from other queues.

It will be discarded because the high-priority-only threshold has been reached.

Question 144

Which of the following is NOT an advantage of deploying queue-groups on a network port?

It enables fine-tuned SLA control that is not possible when using a common set of queues for all L2/L3 services.

It enables CFHP and hierarchy scheduling (egress) for each network interface.

It improves scalability by allowing the use of queues instead of the default set of policers used on network egress.

It allows for enforcing bandwidth reservations of the LSPs that are used by the SDPs configured on the network interfaces.

Question 145

A queue-group template can contain both queues and policers when applied under which conditions?

When applied at the port level for access ingress.

When applied at the FP (Forwarding Pass) level for access ingress.

When applied at the FP (Forwarding Pass) level for network ingress.

When applied at the port level for network egress.

Question 146

According to the SAP-egress policy configured and applied, which queue will forwarding class AF's traffic use?

Policer 2 on the queue-group Q-Group1 instance 1.

Policer 1 on the queue-group Q-Group1 instance 1.

The default policer 1.

AF traffic is dropped.

Question 147

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

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.

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.

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

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.
