Explanations

A corporate manager says wireless phones do not work properly inside the main building.

After a troubleshooting process, the network administrator detects that the voice packets are arriving on the wireless phones with different delay times.

Which of the following performance issues is the company facing?

A.

Jitter

B.

Latency

C.

Attenuation

D.

Frequency mismatch.

A.

The performance issue that the company is facing is most likely jitter.

Jitter refers to the variation in delay of packets arriving at their destination. In this case, the voice packets arriving on the wireless phones are experiencing different delay times, which means they are arriving with varying amounts of jitter.

This can be caused by a number of factors, such as network congestion, poor quality of service (QoS) settings, or problems with the network infrastructure. Jitter can cause poor call quality, dropped calls, and other issues with real-time communication applications like VoIP.

Latency, on the other hand, refers to the delay between sending a packet and receiving a response. While latency can also cause issues with real-time communication, it typically results in delays in conversation rather than varying delay times for individual packets.

Attenuation refers to the loss of signal strength as it travels through a medium like a cable or through the air. This can cause problems with wireless communication, but it is not the most likely cause of the issue described in the scenario.

Frequency mismatch occurs when devices are not using the same frequency or channel for communication. This can also cause issues with wireless communication, but it is not the most likely cause of the issue described in the scenario.
