ENSA 9.1 -- Network Transmission Quality

Front

What happens when the volume of traffic exceeds the network's capacity to transport it?

Back

Devices queue the packets in memory until resources are available.

Front

What is the consequence of queuing packets in a network device?

Back

It causes a delay because new packets have to wait.

Front

What happens if the number of packets to be queued continues to increase?

Back

The device's memory fills up and packets are dropped.

Front

Which Quality of Service (QoS) technique can help manage network congestion? Options: Increasing the bandwidth, Classifying data into multiple queues, Reducing the number of devices on the network, Using a single queue for all data.

Back

Classifying data into multiple queues.

Front

What is the default behavior of packet processing without any QoS mechanisms?

Back

Packets are processed in the order in which they are received.

Front

What protocol is used for Voice over IP (VoIP) digital audio streams?

Back

RTP

Front

What mechanism compensates for jitter in VoIP audio streams?

Back

Playout delay buffer

Front

What happens when jitter exceeds what the DSP can handle in VoIP?

Back

Audio problems are heard.

Front

What is the role of the playout delay buffer in a network?

Back

It compensates for jitter in audio streams.
