Question 1
Your retail company is concerned about their BigQuery analytics spend. The company runs several queries that require the use of the same aggregation for the store ID and real-time sales volume. You need to implement the optimal solution that minimizes analytics spend and returns faster results. What should you do?
Question 2
You are provided a dataset of customer interactions logs, currently stored as compressed JSON files in Cloud Storage. The data is highly nested and semi-structured and needs to be loaded into BigQuery for training a BigQuery ML model. You want to leverage BigQuery's native capabilities for handling this data type, while still maintaining its nested structure. What should you do?
Question 3
You created an analytics environment on Google Cloud so that your data scientist team can explore data without impacting the on-premises Apache Hadoop solution. The data in the on-premises Hadoop Distributed File System (HDFS) cluster is in Optimized Row Columnar (ORC) formatted files with multiple columns of Hive partitioning. The data scientist team needs to be able to explore the data in a similar way as they used the on-premises HDFS cluster with SQL on the Hive query engine. You need to choose the most cost-effective storage and processing solution. What should you do?
Question 4
You have designed an Apache Beam processing pipeline that reads from a Pub/Sub topic. The topic has a message retention duration of one day, and writes to a Cloud Storage bucket. You need to select a bucket location and processing strategy to prevent data loss in case of a regional outage with an RPO of 15 minutes. What should you do?
Question 5
You are migrating your on-premises data warehouse to BigQuery. As part of the migration, you want to facilitate cross-team collaboration to get the most value out of the organization's data. You need to design an architecture that would allow teams within the organization to securely publish, discover, and subscribe to read-only data in a self-service manner. You need to minimize costs while also maximizing data freshness. What should you do?
Question 6
You store and analyze your relational data in BigQuery on Google Cloud with all data that resides in US regions. You also have a variety of object stores across Microsoft Azure and Amazon Web Services (AWS), also in US regions. You want to query all your data in BigQuery daily with as little movement of data as possible. What should you do?

Professional Data 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.
