Anthropic CCDV-F Exam Syllabus Topics:

Anthropic Claude Certified Developer-Foundations Sample Questions:

Question 1

You have just shipped a new Claude-powered application to production. The development phase is complete, and the system is now in active use by internal teams.
The next phase of work for this system is...

A. Running a formal post-deployment review that assesses the development phase before the team does any further work on the system.
B. Operating and maintaining the system, including monitoring, responding to issues, and planning evolution.
C. Retiring the system, since shipping is the final lifecycle stage for any application that reaches production.
D. Handing the system over to a separate operations team that will manage it independently of the development team going forward.

Question 2

You are choosing between using STDIO-based communication and HTTP-based communication for an MCP server. The server will be invoked by a Claude Code session running locally.
Which communication pattern would you use?

A. HTTP polling against the MCP server, treating HTTP as a substitute for the standard MCP communication patterns.
B. HTTP on the grounds that HTTP is preferable to STDIO in any context the application might encounter during normal operation.
C. STDIO because STDIO is well-suited to local process communication and avoids unnecessary network setup.
D. STDIO and HTTP simultaneously for redundancy, with the team running two communication patterns at the same time across Claude Code sessions.

Question 3

You are setting up a CI/CD pipeline for a new Claude application. The pipeline needs to run automated checks on every pull request before code can be merged.
The CI/CD checks would include...

A. Automated tests of the Claude integration only, with linting handled separately during local development on each developer's machine.
B. Automated tests of the Claude integration, linting, and any other standard quality gates the team applies to its other services.
C. Automated linting and security scanning, with Claude integration testing handled manually during pre- release verification by a designated reviewer.
D. A full end-to-end production deployment on every pull request to catch all possible issues before any code is merged into the main branch.

Question 4

The team is debating whether to build a new capability as a custom tool or to use an existing built-in tool that nearly covers the use case but lacks one specific feature.
How would you decide?

A. Identify whether the team has previously built similar custom tools and use those precedents to determine which approach is more consistent with the existing codebase.
B. Evaluate whether the missing feature can be addressed by extending the built-in tool or warrants a custom tool, then choose accordingly.
C. Examine the custom tool option by scoping the implementation effort and determining whether the additional flexibility justifies the development and maintenance cost.
D. Review the built-in tool's documentation and assess whether its existing capabilities are sufficient to cover the use case without any modification or extension.

Question 5

Your Claude application uses tool calling to fetch patient data and generate summary reports. The flow occasionally fails because the model returns a tool_use block that references arguments not present in the schema, and your application code does not handle this case gracefully.
How would you address this?

A. Retry the same request repeatedly until the model returns a valid tool_use block that matches the schema as expected.
B. Stop using tool calling entirely and replace tools with prompted text generation that asks the model to describe what it would do.
C. Log invalid tool_use blocks when they occur and allow the tool dispatch to proceed, relying on the tool's own error handling to surface failures back to the application.
D. Validate the tool_use block's arguments against the tool schema before dispatching the tool and handle invalid arguments as a recognized error path.
