Question
A network technician is troubleshooting VoIP calls that have jumbled and distorted audio. The network technician analyzes the voice VLAN traffic and determines packets on the voice VLAN are being received out of order. Which of the following network metrics are causing the VoIP issues?
A. Jitter
B. Bandwidth
C. Latency
D. Delay
Answer
A. Jitter
Explanation
Jitter is a network metric that refers to the variation in the delay of received packets. When packets arrive at inconsistent intervals, they may be processed out of order, leading to jumbled and distorted audio in VoIP calls.
Here’s why the other options are incorrect:
B. Bandwidth: Bandwidth is the maximum amount of data that can be transmitted over a network connection in a given time period. While insufficient bandwidth can cause issues with VoIP calls, it does not directly cause packets to arrive out of order.
C. Latency: Latency is the time it takes for a packet to travel from its source to its destination. High latency can cause delays in VoIP calls but does not typically result in packets being received out of order.
D. Delay: Delay is similar to latency and refers to the time it takes for a packet to travel across a network. Like latency, delay can cause slowdowns in VoIP calls but does not directly lead to packets arriving out of order.
In summary, jitter is the network metric responsible for causing VoIP issues where packets are received out of order, resulting in jumbled and distorted audio.
