In this lesson
Prepare for the Claude Certified Developer – Foundations exam, on the exam guide version 1.0, effective July 2026. In this lesson: tokens and the context window, sampling and non-deterministic outputs (and why current models reject temperature), fast mode, adaptive thinking and effort, and zero-shot, one-shot, and few-shot prompting. Includes three original practice questions.
Preview the topics
- Driftwood’s test checks that the tag Claude gives a listing matches one exact string, and it fails one run in five, with the same prompt. What should change?
- Driftwood’s live chat runs on Opus 5.5, and the team wants long answers to stream faster, with the same quality. Which setting fits?
- Driftwood’s prompt shows one example of a listing summary, and Claude now copies the wording and the length of that example for every product. What should change?
