4A0-107 Exam Dumps - Nokia SRC Certification Questions and Answers

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.

TRUE

FALSE

Classification rules must specify both an FC and a profile for the packets.

A network policy is applied at a physical port.

Classification is performed with behavior-aggregate statements only.

Match criteria can be chosen from dot1p, DSCP, and EXP fields in the packet.

On the SDP.

On the access ingress port.

On the egress MDA.

On the SAP.

On the ingress MDA.

Signal degradation, attenuation, line loss

It will be discarded because the high-priority-only threshold is exceeded.

It will be queued but re-marked as "out-of-profile."

It will be queued in the reserved portion of the buffer pool and remain "in-profile."

It will be queued in the shared portion of the buffer pool but contend for shared buffer space with packets from other queues.

It will be queued in the shared portion of the buffer pool but may be dropped if the buffer utilization exceeds the start-average value of the low slope.

On the network egress port.

On the SAP.

On the ingress MDA.

WRED monitors the shared buffer space utilization over a period of time.

WRED disables the TCP slow-start congestion control mechanism.

WRED uses two configurable slopes for each buffer pool: a high slope and a low slope.

WRED uses the shared buffer utilization, instead of the individual queue depth, to get a better picture of the average resource utilization of the shared buffer space.

WRED polices the shared buffer pool and marks all packets above a certain rate as "discard eligible."
