What are two probable causes of a VoIP implementation experiencing dropouts, echoes, or glitches? (Choose two.)
A. high bandwidth
B. high latency
C. high cable voltage
D. high cable impedance
E. high jitter

A. high bandwidth
B. high latency
C. high cable voltage
D. high cable impedance
E. high jitter

Answer:

First, let’s the understand VoIP (Voice over IP): VoIP converts analog voice signals into digital data packets for transmission over IP networks. 

Given Options: Step by Step Answering

a) High bandwidth

  • VoIP usually requires minimal bandwidth, so excess bandwidth is not a cause of dropouts or glitches.

b) High Latency

  • Latency refers to the delay in data transmission over a network. When latency is high, it can result in delayed audio transmission, causing echoes or dropouts in a VoIP call.

c) High cable voltage

  • This is not typically related to network issues affecting VoIP.

d) High cable impedance

  • This is related to electrical resistance in the cable, but it’s not a common cause for VoIP quality issues.

e) High Jitter

  • Jitter refers to variations in packet arrival times. When jitter is high, packets arrive out of order, which can cause glitches and audio distortion during VoIP calls.

Final Answer:

Based on the above analysis, the correct answer is:

B. High latency
E. High jitter

Two probable causes of a VoIP implementation experiencing dropouts, echoes, or glitches are high latency and high jitter.

These are both network-related issues that directly impact the quality of VoIP communications by affecting how voice data packets are transmitted and received.
