How does latency differ from throughput?

Latency measures data rate, while throughput measures delay.

Latency is measured in bits per second, while throughput is measured in milliseconds.

Latency measures delay, while throughput measures data rate.

Latency and throughput are the same measurement.

A user runs a speed test and gets 100 Mbps download and 100 Mbps upload on a 200 Mbps symmetric plan. The user then runs a second speed test and gets 50 Mbps download and 50 Mbps upload. What is the most likely explanation for the difference?

The second test was affected by higher latency, which directly reduced throughput.

The bandwidth of the plan changed between the two tests.

The second test may have been affected by network congestion or other traffic on the connection.

The first test measured bandwidth, while the second measured throughput.

Which of the following is a factor that can reduce throughput below the bandwidth of a link?

Increasing the link's bandwidth

A network engineer is validating a new 10 Gbps link between two buildings. An Iperf test shows 9.5 Gbps throughput, but an internet speed test from a computer on the same link shows only 800 Mbps. The engineer needs to explain the discrepancy to management. Which explanation is most accurate?

The link's bandwidth is actually 800 Mbps, and the Iperf test is wrong

The Iperf test measures throughput on the local link, while the speed test measures throughput to an external server, which is limited by internet factors

The Iperf test is inaccurate because it does not use TCP

The speed test is inaccurate because it measures upload speed instead of download speed
