Enterprise Module 9 Network Transmission Quality

Prioritizing Traffic: What is the purpose of Quality of Service (QoS)?

• a) To prioritize traffic and ensure high-quality delivery
• b) To increase network capacity
• c) To eliminate congestion on routers
• d) To encrypt data for secure transmission

Prioritizing Traffic: What is congestion in networking?

• a) When data packets are lost during transmission
• b) When multiple communication lines aggregate onto a single device
• c) When the network experiences a complete outage
• d) When devices fail to connect to the network

Prioritizing Traffic: How does congestion affect packet transmission?

• a) It increases the speed of packet transmission
• b) It decreases the latency in the network
• c) It causes delay and can result in dropped packets
• d) It improves the overall network performance

Prioritizing Traffic: What happens when devices queue packets?

• a) They encrypt the packets for secure transmission
• b) They prioritize large data packets over smaller packets
• c) They hold the packets in memory until resources are available to transmit them
• d) They drop the packets to reduce congestion

Prioritizing Traffic: How can QoS help with packet queuing and congestion?

• a) By eliminating the need for packet queuing
• b) By prioritizing data into multiple queues
• c) By reducing the overall network traffic volume
• d) By increasing the memory capacity of networking devices

Bandwidth, Congestion, Delay, and Jitter : Which term refers to the situation when there is a high volume of traffic on the network, causing performance degradation?

• a) Bandwidth
• b) Congestion
• c) Delay
• d) Jitter

Bandwidth, Congestion, Delay, and Jitter: Which term describes the time it takes for a packet to travel from the source to the destination?

• a) Bandwidth
• b) Congestion
• c) Delay
• d) Jitter

Bandwidth, Congestion, Delay, and Jitter: Which delay represents the variable amount of time a frame or packet waits to be transmitted on the link?

• a) Queuing delay
• b) Serialization delay
• c) Propagation delay
• d) De-jitter delay

Packet Loss: What happens to packets in a network without any QoS mechanisms in place?

• a) They are processed in the order they are received
• b) They are dropped indiscriminately
• c) They are prioritized based on their content
• d) They are delayed until congestion subsides

Packet Loss: In the context of Voice over IP (VoIP), what is the purpose of the playout delay buffer?

• a) To handle packet loss
• b) To compensate for jitter
• c) To prioritize real-time packets
• d) To increase the overall network capacity
