Anthropic Claude Certified Developer-Foundations CCDV-F Prüfungsfragen mit Lösungen (Q25-Q30):

25. Frage
You are setting up Claude Code for a new project repository. Your team has shared coding standards, preferred libraries, and project-specific context that every developer working on the repository should have available when they use Claude Code.
How would you set this up?

A. Initialize Claude Code in the repository and document the standards and project-specific context in a CLAUDE.md file at the repository root.
B. Document the standards in a separate wiki page maintained outside the repository so the documentation stays decoupled from the source code.
C. Configure Claude Code through environment variables that each developer sets on their own machine when they begin working in the repository.
D. Add the coding standards and project context to the repository's existing README file and direct developers to reference it when starting Claude Code sessions.

Antwort: A

Begründung:
Option C is correct. Claude Code uses CLAUDE.md as the standard mechanism for supplying persistent project-level instructions and context. Anthropic's Claude Code documentation states that project instructions can be stored in ./CLAUDE.md or ./.claude/CLAUDE.md and shared with team members through source control. Appropriate content includes coding standards, architectural decisions, project conventions, build/test commands, preferred workflows, and information developers would otherwise need to repeat to Claude during every session. The /init command can also generate an initial CLAUDE.md based on the repository.
A wiki may be valuable for human documentation, but Claude Code does not automatically receive that material as project context. B creates developer-specific configuration and risks inconsistency across the team. D places the information in a human-facing README but does not use Claude Code's purpose-built persistent instruction mechanism.
Therefore, C gives the repository a shared, version-controlled source of Claude-specific project guidance.
Relevant Study Guide topics: CLAUDE.md, project configuration, persistent instructions, repository context, team standards, and configuration management.

26. Frage
A new Claude model release includes performance improvements for several reasoning tasks but has changed the format of its responses to system prompts that use multi-section instructions. Your application uses multi- section system prompts heavily. Initial evaluation on the application's actual workload shows the new model performs 8 percent better on reasoning tasks but produces malformed output on roughly 3 percent of requests because of the format change. The team is debating whether to upgrade.
How would you decide?

A. Upgrade immediately, because the 8 percent reasoning improvement outweighs the 3 percent malformed output rate across the application's typical request distribution.
B. Upgrade and add a downstream validation step that catches the 3 percent malformed output before it reaches users, treating the validation step as the team's mitigation for the format change.
C. Adapt the application's system prompt to the new model's format expectations and re-evaluate, then upgrade only if the adapted prompt eliminates the malformed output while preserving the reasoning improvements.
D. Stay on the previous model permanently to avoid the malformed output rate and any future format changes that subsequent model releases might introduce in the application.

Antwort: C

Begründung:
The supplied examination page marks B . The scenario already demonstrates why model upgrades must be treated as evaluated software changes rather than automatic replacements: the new model improves one metric while introducing a regression in another.
Anthropic's official model-selection guidance recommends creating benchmark tests specific to the application's use case, testing models with the application's actual prompts and data, comparing response quality and edge-case performance, and weighing performance against operational tradeoffs. Therefore, the correct action is to adapt the multi-section system prompt to the new model's behavior and repeat the evaluation. Only after the formatting regression is eliminated-or reduced below an explicitly acceptable threshold-should the upgrade proceed.
A incorrectly assumes that an 8% reasoning improvement numerically compensates for a 3% malformed- output rate; these metrics measure different consequences and cannot simply be subtracted. C treats the known incompatibility only downstream instead of first correcting the prompt/model interaction. D permanently rejects future improvement and is inconsistent with controlled lifecycle evolution.
The engineering principle is migration through regression testing and adaptation , not blind upgrading or permanent version avoidance.
Relevant Claude Developer topics: Systems Life Cycle, model migration, regression evaluation, prompt adaptation, compatibility testing, deployment gates, and continuous evolution .

27. Frage
A teammate has asked you to explain why the team's Claude application is billed for output tokens at a different rate than input tokens. They had assumed the rate was the same for both.
How would you explain the difference?

A. Output tokens are typically billed at a lower rate than input tokens, because output tokens are cheaper to produce than input tokens are to process.
B. Output tokens are typically billed at the same rate as input tokens, and the apparent rate difference is a billing error to report to Anthropic.
C. Output tokens are typically billed at a higher rate than input tokens, and cost models for the application should reflect both rates separately.
D. Output tokens are not billed at all, because cost is determined entirely by the input tokens sent to the model on each request.

Antwort: C

Begründung:
The supplied Claude Certified Developer Foundations question identifies D as the correct answer. Anthropic prices input and output tokens separately, so application cost models must independently account for the number of tokens supplied to Claude and the number generated in response.
Anthropic's official pricing documentation confirms that output-token pricing is normally higher than base input-token pricing. For example, current Claude models maintain distinct columns for base input tokens and output tokens; the exact dollar amounts depend on the selected model. This distinction matters because an application with relatively small prompts but very large generated responses can incur substantial output- token expenditure even when input volume is modest.
Therefore, cost forecasting should use approximately: input tokens × input rate + output tokens × output rate , with additional adjustments where prompt caching, batch processing, server tools, or other pricing modifiers apply. Option A incorrectly assumes equivalent rates, B reverses the normal relationship, and C incorrectly excludes generated tokens from billing.
Relevant Claude Developer topics: Claude API Mechanics, token accounting, model pricing, input/output token usage, cost modeling, prompt caching, and production API economics .

28. Frage
You are choosing a Claude model for a high-volume classification task. Each classification is straightforward, latency requirements are tight, and per-request cost matters at scale.
Which model would you choose?

A. Multiple Claude models in series, where each request runs through more than one model and the application combines the outputs into a final classification.
B. The largest, highest-capability Claude model, to maximize quality on every classification the application produces during normal operation across all requests.
C. A mid-tier Claude model selected by default, because mid-tier models balance quality and cost in a way the team can apply across most tasks.
D. A smaller, faster Claude model, because the task is straightforward and the workload prioritizes latency and per-request cost at scale.

Antwort: D

Begründung:
Option C matches Anthropic's efficiency-first model-selection guidance. For a straightforward, high-volume workload where latency and unit cost are explicit constraints, the correct starting point is a faster, economical model that can meet the task's quality threshold. Anthropic specifically lists high-volume straightforward tasks, tight latency requirements, and cost-sensitive implementations as cases where an efficiency-first model choice is appropriate.
The crucial qualification is that "smaller" does not mean accepting inadequate quality. The team should evaluate the candidate against representative classification examples and defined accuracy criteria. If it passes, moving to a larger model adds cost and often latency without delivering required business value.
A selects a mid-tier model by convention rather than workload evidence. B multiplies inference calls, generally increasing both latency and cost for a simple classification problem. D optimizes maximum capability even though the task does not require frontier-level reasoning.
Therefore, C is the appropriate initial model choice, followed by workload-specific validation. Relevant Study Guide topics: Claude model selection, efficiency-first design, classification workloads, throughput, latency, per-request economics, evaluation, and quality/cost tradeoffs.

29. Frage
Your Claude application's token costs have grown faster than expected. The team has not been tracking token usage by feature, so the team cannot identify which features are driving cost. The team is debating how to respond.
How would you respond?

A. Tell the team that cost growth is unavoidable as the application scales and that no investigation will change the trajectory of the application's cost over the next several quarters.
B. Switch every feature to the smallest model to cut cost broadly across the application during normal operation.
C. Add token usage tracking by feature to the application's logging so the team can identify which features drive cost before recommending changes.
D. Reduce token usage uniformly across all features by half, applying the cut evenly across the application during normal operation.

Antwort: C

Begründung:
Option D follows the fundamental optimization rule of measuring before changing. Without feature-level usage telemetry, the team cannot know whether cost growth comes from request volume, long prompts, excessive outputs, low cache-hit rates, expensive models, agent loops, tool results, or one particularly inefficient workflow.
Anthropic's Usage and Cost API exists specifically to provide granular historical usage and cost information.
It supports token tracking and breakdowns by dimensions including model, workspace, service tier, API key, context window, and other usage characteristics. Anthropic describes this data as useful for monitoring, cost reconciliation, optimization, and determining whether system changes improve efficiency.
B applies a model downgrade indiscriminately and may damage features whose quality requirements genuinely demand a stronger model. C similarly imposes an arbitrary token reduction without identifying where waste exists. A abandons cost management entirely.
The correct lifecycle is instrument, establish a baseline, identify high-cost features, analyze why they are expensive, apply targeted optimizations, and measure again. Relevant Study Guide topics: observability, usage telemetry, cost attribution, token accounting, production monitoring, capacity planning, and evidence- driven optimization.
