Which evidence-based metric is most useful for diagnosing whether a network link is causing VoIP call quality degradation?

Accepted Answer

Jitter, latency, and packet loss measurements

Answer

Total bandwidth capacity of the link

Answer

Number of connected devices

Answer

Link-layer frame size settings

Question 2

A technician uses 'pathping' in Windows to investigate a slow connection. What evidence does this tool combine compared to ping alone?

Accepted Answer

It combines traceroute hop mapping with per-hop packet loss and latency statistics

Answer

It tests UDP connectivity instead of ICMP

Answer

It measures DNS resolution times at each hop

Answer

It shows physical port speeds at each router

In an evidence-based network design review, what does 'variance analysis' compare?

Accepted Answer

Actual measured network performance against the documented baseline or design targets

Answer

The cost of two competing vendors

Answer

Number of users on each network segment

Answer

Physical cable distances against theoretical limits
