Question 1 of 53

You are starting a new Claude application and have a small set of well-labeled examples that demonstrate the desired output format. You want to use these examples to guide Claude’s behavior. How would you guide the application’s behavior?
Answer choices
Show answer

Correct answer: D

Multi-shot prompting includes several labeled input-output examples directly in the prompt, giving Claude an immediate pattern to follow. The examples demonstrate both the required format and the intended behavior for the current request, which is especially useful when only a small example set is available. Zero-shot prompting provides no such format demonstration, while custom training is unnecessary for a small set of examples and retrieval alone does not ensure the examples are presented to Claude.

Question 2 of 53

Your Claude application’s content policy specifies categories of content it should not produce under any circumstance. The application currently has no mechanism to enforce this policy, and content matching these categories is appearing in the application’s output. How would you enforce the content policy?
Answer choices
Show answer

Correct answer: C

Deterministic output filtering enforces the content policy by evaluating every generated response before it is shown to a user and blocking or handling prohibited content consistently. A system prompt can guide model behavior, but it is not a guaranteed control and should not be the sole enforcement mechanism for categories that must never appear. User reporting occurs only after exposure, whereas pre-delivery filtering prevents the violation from reaching users.

Question 3 of 53

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?
Answer choices
Show answer

Correct answer: B

Adapting the system prompt to the new model’s format expectations tests whether the regression is caused by prompt-model interaction rather than an unavoidable model limitation. Re-evaluating on the application’s real workload verifies that structured output remains reliable while retaining the reasoning improvement. A downstream validator may catch failures but does not address the source of the malformed responses, while an immediate upgrade accepts an unvalidated production risk.

Question 4 of 53

Your team’s Claude application has been in production for a year, and the team has decided to formalize its testing strategy. Currently, the team writes ad- hoc tests for individual features but has no overall testing approach. What testing approach would you formalize?
Answer choices
Show answer

Correct answer: B

A layered testing strategy provides appropriate coverage at different levels of the application. Unit tests validate individual functions quickly, integration tests verify that the application interacts correctly with Claude, and end-to-end tests confirm that critical user workflows work as intended. Applying these test types consistently creates a maintainable, repeatable quality process rather than relying on feature-specific ad-hoc testing. End-to-end tests alone are slower and less effective at isolating failures.

Question 5 of 53

Your Claude application makes high-volume API calls during business hours and very few calls overnight. The team is concerned about staying within rate limits during peak hours and wants to understand how the Claude API enforces those limits. How would you proceed?
Answer choices
Show answer

Correct answer: D

Claude API rate limits define the allowed request and token throughput over specific time windows, so the application must first identify the applicable limits and keep peak-hour traffic within them. When a limit is reached, exponential backoff spaces retries progressively, reducing repeated failures and allowing capacity to recover. Smoothing or consolidating traffic may help operationally, but neither replaces designing against the documented limits and handling 429 responses correctly.

Stories from the certified

Charles Sirois
Canada
As this was my first certification exam, I was understandably nervous about what to expect. These study materials made the preparation process much easier, and many of the questions closely reflected those on the actual exam.
Lance Chambers
United States
Wasted about a month going through the free dump sites scattered all over reddit, half the answers were wrong and the other half were for a version of the exam that doesn't even exist anymore. Eventually gave in and paid the small fee here, and the difference was night and day.
Alisha Kelly
Italy
Honestly, I had already gone through the official documentation quite thoroughly, but still didn't feel fully confident going in. This helped things finally click for me. I realized I knew the material, but just hadn't connected all the pieces yet.
Casper Claassen
Netherlands
Used this along with Microsoft Learn and the combo worked really well. The practice questions made the stuff I'd read actually stick. Passed first attempt, no complaints from me.
Gabriele Ghesla
Italy
The content is accurate and clearly presented, and it's more affordable than competitors. The team has been incredibly responsive whenever I've had an issue, and they've been open to small changes that improve the platform.
