About the Claude Certified Developer - Foundations exam

The Claude Certified Developer - Foundations (CCDV-F) is a Foundations-level certification. It covers agents, Claude application integration, Claude Code, evals, model optimization, prompts and context, security, tools, and MCP. The exam has 53 questions and runs 120 minutes. You need a scaled score of 720 out of 1000 to pass.

The 20 practice questions on this page are original independent practice mapped to the public blueprint and official Claude learning material and balanced across the exam domains using the official exam guide weighting. They use the same scenario-based style as the real CCDV-F exam.

Frequently asked questions about the Claude Certified Developer - Foundations exam

What does CCDV-F test most heavily?+

Applications and Integration carries the largest public blueprint weight. Expect practical decisions around Messages API behavior, application state, streaming, tools, agents, cost, safety, and MCP.

Do I need hands-on API experience?+

Hands-on experience is the most useful preparation because the certification targets developers building Claude applications. Build a small agent loop, tool integration, eval suite, and safe authorization boundary.

Are these real exam questions?+

No. These are original study questions based on public blueprint topics and official documentation, not live exam recollections or dumps.

Sample Claude Certified Developer - Foundations questions

Three examples from the 20-question quiz. Answers stay hidden until you reveal them.

Sample Question 1Applications and Integration

A worker may retry after a network timeout while executing a payment-refund tool. What application control is essential?

AAutomatic retries with no limit
BA higher temperature
CAn idempotency key and server-side duplicate check around the consequential operation
DA longer tool description only
Show answer
Answer: C — An idempotency key and server-side duplicate check around the consequential operation

Network ambiguity can cause a successful action to be repeated. Idempotency must be enforced by the application or tool service, not inferred by the model.

Sample Question 2Applications and Integration

Every API request fails immediately with an authentication error before any output tokens are produced. What should the developer inspect first?

APrompt wording
BAPI credentials, request headers, account access, and endpoint configuration
CThe tool schema descriptions
DThe model's reasoning quality
Show answer
Answer: B — API credentials, request headers, account access, and endpoint configuration

An authentication failure occurs before model generation. Debug transport and credential configuration before changing prompts or application logic.

Sample Question 3Applications and Integration

An application needs a response that downstream code can safely parse into a fixed object. What is the strongest design?

AUse a supported structured-output schema and still validate the received object before side effects
BExtract fields with regular expressions from an essay
CRetry forever when parsing fails
DAsk for valid JSON in prose and trust the result
Show answer
Answer: A — Use a supported structured-output schema and still validate the received object before side effects

Schema-constrained output reduces formatting variance, while application validation remains necessary before using data in consequential operations.
