Question 1
You are optimizing the training of a 175-billion parameter LLM on Gemini Enterprise Agent Platform. You have provisioned a TPU v5p Pod slice with 32 chips for the job. You initially ran the training using standard data parallelism, but the job immediately failed with an out-of-memory (OOM) error. You need to implement a training strategy that resolves the memory issue and minimizes training latency. What should you do?
Question 2
You are building an ML workflow that preprocesses data, trains a model with hyperparameter tuning, and deploys the best model to an Agent Platform endpoint. Your preprocessing step takes two hours and outputs a 100 GB dataset. You run experiments daily with different model architectures using the same preprocessing step. You need to automate this process and optimize the pipeline runs to minimize cost and time. What should you do?
Question 3
You deployed a conversational application that uses Gemini. You recently collected thousands of rows of user feedback about the verbosity and accuracy of the model's responses. The feedback indicated that the responses are factually correct but users want different levels of verbosity depending on the type of question. You need to adjust the model to return responses that are more consistent with users' expectations. You want to use a scalable solution and minimize application maintenance. What should you do?
Question 4
You have a high-traffic ecommerce application that uses a recommendation model deployed on an Agent Platform endpoint. During flash sales, traffic quickly spikes from 1,000 to 50,000 queries per second (QPS). During these spikes, the application returns 503: Service Unavailable errors because the autoscaler cannot provision new resources quickly enough to meet the sudden demand. Your need to eliminate service disruptions during the start of the sale. How should you configure the endpoint?
Question 5
You work for an international bank. Your team is developing a generative AI application that summarizes complex financial reports. You need to implement an automated, scalable solution to evaluate and quantify the quality of generated summaries against the previous version of the solution. What should you do?
Question 6
You work for a retail company. You have a managed tabular dataset in Gemini Enterprise Agent Platform that contains regional sales data for each item across stores. The dataset includes several features, such as store name, items sold, and sale timestamp. You want to use the data to train a classification model that predicts whether an item will sell out in each store in the coming week. You need to split the data between the training, validation, and test sets. What approach should you use to split the data?

Professional Machine Learning Engineer Practice and Access FAQs

Understand review, study tools and access before choosing your next step.

Who verifies the questions and answers?

Subject matter expert trainers in each niche review every question and answer before it enters the ExamPrepare database. Answer votes and discussions add perspectives after publication; they do not replace this review. Learn more on our methodology page.

How closely does the simulator match an exam?

The simulator uses vendor-style layouts and supported question interactions to help you practise navigation and pacing. Choose learning, practice or timed exam mode. Formats vary by exam; try the five-question sample to see the experience available for your certification.

What are hot questions?

Hot questions help you prioritise questions with stronger reporting or answer-vote activity. In the reading library, the filter selects questions with at least three recorded sightings or at least three votes for an answer. It has no recency cutoff and does not predict your exam questions. Use it alongside weaker topics and the exam objectives.

Can I read questions without starting a simulation?

Yes. Paid reading access lets you display 6, 10, 25, 50 or 100 questions per page, select a question range, filter for hot questions and show answers while reading. Choose the simulator whenever you want a learning, practice or timed exam session.

Can I download questions and answers as a PDF?

Each exam overview offers a free PDF sample of up to 10 supported questions. With paid reading access, you can also export supported single- and multiple-choice questions with their answers and images. Interactive question formats need the website and are not included as interactive PDF exercises.

How do votes and discussions relate to verified answers?

SME trainers review the questions and answers before publication. Imported answer reports show aggregate responses, while on-site votes and comments reflect participation on ExamPrepare. Use discussion to compare reasoning and investigate disagreements; a majority vote alone does not prove an answer correct.

What does a purchase unlock?

A purchase unlocks the complete question bank for the selected exam, access without CAPTCHA checks, reading controls, supported PDF exports and full learning, practice and timed simulation features. It covers that exam for the duration of the plan you choose, rather than every certification in the catalogue.

Where can I find my purchased exams and expiry dates?

Sign in to the account used for your purchase and open your profile. Your purchased exam library shows study links and access expiry dates so you can return to an exam and check how much access time remains.
