Question 1 of 488

A company makes forecasts each quarter to decide how to optimize operations to meet expected demand. The company uses ML models to make these forecasts.

An AI practitioner is writing a report about the trained ML models to provide transparency and explainability to company stakeholders.

What should the AI practitioner include in the report to meet the transparency and explainability requirements?

Answer choices
Show answer

Correct answer: B

Partial dependence plots (PDPs) show how changes in an input feature affect a model’s prediction while averaging the effects of other features. They help stakeholders understand which variables influence demand forecasts and whether the relationship is positive, negative, or nonlinear. This provides model-level transparency without requiring stakeholders to interpret training code or raw sample data. Convergence tables describe training progress, but they do not explain how the trained model reaches individual predictions.

Question 2 of 488

A law firm wants to build an AI application by using large language models (LLMs). The application will read legal documents and extract key points from the documents.

Which solution meets these requirements?

Answer choices
Show answer

Correct answer: C

A summarization chatbot uses an LLM to identify and condense the main arguments, facts, obligations, and conclusions in legal documents. It can present those key points in a concise form while retaining the source document’s context. Named entity recognition extracts specific entities such as people, organizations, or dates, but it does not generally produce an overall summary of the document.

Question 3 of 488

A company wants to classify human genes into 20 categories based on gene characteristics. The company needs an ML algorithm to document how the inner mechanism of the model affects the output.

Which ML algorithm meets these requirements?

Answer choices
Show answer

Correct answer: A

Decision trees provide interpretable classification by showing the sequence of feature-based splits that leads to each category prediction. Each branch documents how a gene characteristic influences the model’s decision, making the internal logic easy to inspect and explain. They also support multiclass classification, including assignment across 20 gene categories. Neural networks are generally less transparent, while linear and logistic regression do not provide the same rule-based decision path.

Question 4 of 488

A company has built an image classification model to predict plant diseases from photos of plant leaves. The company wants to evaluate how many images the model classified correctly.

Which evaluation metric should the company use to measure the model's performance?

Answer choices
Show answer

Correct answer: B

Accuracy measures the proportion of image predictions that match the correct plant disease labels. Because this is a classification task with discrete categories, it directly shows how many images the model classifies correctly out of the total evaluated images. R-squared and RMSE are regression metrics for numeric predictions, while learning rate is a training hyperparameter rather than an evaluation metric.

Question 5 of 488

A company is using a pre-trained large language model (LLM) to build a chatbot for product recommendations. The company needs the LLM outputs to be short and written in a specific language.

Which solution will align the LLM response quality with the company's expectations?

Answer choices
Show answer

Correct answer: A

Adjust the prompt to explicitly request brief product recommendations in the required language. Prompt instructions guide the model’s output format, tone, length, and language without changing the underlying model. Increasing temperature or Top K generally makes responses more varied and less predictable, rather than enforcing these requirements. Selecting a different model size does not directly control the response style or language.

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.

I don't usually leave reviews, but this one felt worth sharing. The questions were quite close to what actually appeared on the exam, more than I expected. I spent about a week going through the material before my test, and it helped me feel more prepared.

Does what it says it does. Content felt solid, nothing confusing to navigate and I didn't run into any weird issues. I been putting off scheduling the exam for a while and going through this gave me enough confidence to finally book it and pass.
Neil Savage
