NQA is a real-time network performance detection and statistics technology. NQA does not support statistics on which of the following network information?

Question

Options

• ALink MTU
• BNetwork jitter
• CPacket loss rate
• DResponse time

• A
  80% (45)
• B
  5% (3)
• C
  4% (2)
• D
  11% (6)

Explanation

Link MTU (A) is correct because NQA operates by injecting test probe packets into the network and analyzing the responses to measure dynamic performance metrics. MTU (Maximum Transmission Unit) is a static interface configuration parameter - a fixed property of a link - not a time-varying performance characteristic that probe-based measurements can collect. NQA's statistical engine is designed for real-time performance data, not interface configuration discovery.

B, C, and D are all wrong as distractors because they represent exactly what NQA is built to measure: jitter (variation in packet delay, captured by timing sequential probes), packet loss rate (calculated from sent vs. received probe counts), and response time (round-trip time measured from probe send to reply receipt). These three are core NQA output metrics.

Memory tip: Think of NQA as a stopwatch, not a tape measure. It times packet journeys (response time, jitter, loss) but cannot measure the physical "width" of the road (MTU) - that's set by the interface, not discovered through probes.
