Comparing throughput and latency | AWS Certified AI Practitioner (AIF-C01) original practice question

1.3Standard

A summarization API is slow under concurrent use.

Clarify performance goals.

Choose two measurements.

Hint 1: Focus on the requirement

Identify what must change and what must remain unchanged. Then choose the command whose scope matches that requirement.

Hint 2: Check each command's role

Separate commands that display information, change state, remove data, or affect a child process.

Detailed explanation

CorrectMeasure p50, p95, p99, timeouts, and errors against user impact

Long-tail delay is visible.

CorrectTrack concurrency, queue length, tokens, throughput, and cost

Bottlenecks can be found.

IncorrectUse only average latency for all users

Long tails are hidden.

IncorrectUnlimited concurrency always lowers latency

Quota and contention exist.

An example you can run in a temporary verification environment.

Foundation review

Check whether the command acts on the current shell, a new process, an existing process, or a file.

Use the supplied command and compare the output with the expected result.
