Anthropic CCDV-F Exam Syllabus Topics:

Anthropic Claude Certified Developer-Foundations Sample Questions:

Question 1

Your application uses the Messages API to handle multi-turn conversations. Each new turn resends the entire conversation history, and your token costs are growing as conversations get longer. You suspect there is a more efficient approach.
How would you address this?

A. Switch to the Batch API for every turn so the per-call cost is reduced, treating the batch as the team's primary cost-control mechanism for multi-turn work.
B. Truncate every conversation to the last two messages so that token usage stays low and costs remain predictable across the application's normal operation.
C. Use prompt caching to reuse the static portions of the conversation context across turns instead of paying for them at the normal input-token rate on every request the application sends.
D. Summarize each conversation after every turn and replace the full history with the summary on the next request, reducing token count at the cost of fidelity.

Question 2

Your Claude application validates structured output but has been treating validation failures as terminal errors. Each validation failure causes the entire user request to fail. The team wants to handle validation failures more gracefully.
How would you handle the validation failures?

A. Pass validation failures directly to downstream systems and let each downstream system decide how to handle the malformed output.
B. Disable output validation until the underlying cause of validation failures has been identified and addressed in a future release.
C. Treat validation failures as a recognized error path that triggers retry, repair, or fallback logic before failing the user request.
D. Tell users that validation failures are unavoidable and instruct them to perform manual accuracy checks before relying on outputs.

Question 3

Your team is preparing a new Claude application for production, and the product team has asked for a cost projection. The team needs to estimate the cost based on expected request volume, average input length, and average output length. How would you build the projection?

A. Build a cost model that combines expected request volume and average input tokens, treating output tokens as a small enough share of cost to leave out of the projection.
B. Build a cost model based on expected request volume and the chosen model's pricing, treating average input and output token counts as variables to be estimated post-launch.
C. Build a cost model that combines expected request volume, average input tokens, average output tokens, the chosen model's pricing, and any caching benefits.
D. Build a cost model that uses the average per-request cost from a similar Claude application the team built last year, scaling that figure by expected request volume.

Question 4

You are building a Claude application that needs to deliver model output to end users as it is generated, instead of waiting for the full response to complete.
The Claude API mechanism you would use is...

A. Prompt caching, which speeds up the cost profile of future requests and does not affect the delivery timing of the first response.
B. Streaming responses, which deliver tokens incrementally as the model generates them so users see output progressively.
C. The Batch API, which delivers full responses after a delay suitable for non-interactive workloads.
D. Structured JSON output, which delivers responses only after the model has finalized the JSON shape across the entire response.

Question 5

Your team is choosing how to add a capability to a Claude application. You want to apply the appropriate option, whether built-in tool, custom tool, Skill, or MCP server, based on the use case.
You would choose the option that...

A. Matches the use case's scope, reuse needs, and integration context.
B. Is the easiest to build given the team's current development tools and workflows.
C. Is the most familiar to the team based on prior experience with similar capabilities.
D. Is the newest available option among built-in tools, custom tools, Skills, and MCP servers.
