Prepare for the Claude Certified Developer – Foundations exam, on the exam guide version 1.0, effective July 2026.

Includes three original practice questions.

- Driftwood’s refund requests follow a fixed policy: check the order, check the delivery date, then apply one of three outcomes. Which architecture fits best?
- A lead agent sends each subagent the same short line: “research the competitors”. Three subagents return the same three companies. What is the most likely fix?
- Driftwood’s team wants to split a tightly coupled refactor across five parallel subagents, each editing related files. What is the best advice?
