What is the maximum acceptable latency for voice traffic?

• 400 ms

• 150 ms

• 30 ms

• 80ms

What is the maximum acceptable jitter for video traffic?

• 30 ms

• 50 ms

• 150 ms

• 400 ms

What is the minimum bandwidth requirement for voice traffic?

• 384 Kbps

• 150 ms

• 30 Kbps

• 1%

Which protocol is used by data applications that have no tolerance for data loss?

• UDP

• TCP

• RSTP

• HTTP

What is the maximum acceptable packet loss for both voice and video traffic?

• 1%

• 5%

• 10%

• 0.5%

Which UDP port is used for RSTP and should be prioritized over less delay-sensitive traffic?

• 80

• 443

• 554

• 8080

What is the minimum bandwidth requirement for video traffic?

• 30 Kbps

• 150 ms

• 384 Kbps

• 1%

Which type of traffic is described as predictable and smooth?

• Video traffic

• Data traffic

• Voice traffic

• Email traffic

What is the maximum acceptable latency for video traffic?

• 150 ms

• 400 ms

• 30 ms

• 50 ms

Why does it make no sense to retransmit voice packets if they are lost?

• voice traffic is not sensitive to delays

• voice packets must receive a lower priority

• voice is sensitive to delays, retransmission would cause further delay

• voice traffic requires less bandwidth
