Three of the 349 questions in this pack

Question 1

Your company is in a highly regulated industry. One of your requirements is to ensure individual users have access only to the minimum amount of information required to do their jobs. You want to enforce this requirement with Google BigQuery. Which three approaches can you take? (Choose three.)

  1. Disable writes to certain tables.
  2. Restrict access to tables by role.
  3. Ensure that the data is encrypted at all times.
  4. Restrict BigQuery API access to approved users.
  5. Segregate data across multiple tables or databases.
  6. Use Google Stackdriver Audit Logging to determine policy violations.
Show answer and explanation

Correct answer: B, D, E. Restrict access to tables by role; Restrict BigQuery API access to approved users; Segregate data across multiple tables or databases.

To enforce minimum access requirements, you should restrict access to tables by role (B), allowing different users different permissions based on job function. Restricting BigQuery API access to approved users (D) ensures only authorized personnel can query data. Segregating data across multiple tables or databases (E) enables fine-grained control by separating sensitive information so users only access what they need. Together, these three approaches implement least privilege through access control, API restriction, and data isolation.

Why the other options are wrong

  • A. Disabling writes does not control read access or limit information exposure.
  • C. Encryption protects data in transit and at rest but does not restrict which users can access it.
  • F. Audit logging detects violations after they occur but does not prevent unauthorized access proactively.

Question 2

You are designing a basket abandonment system for an ecommerce company. The system will send a message to a user based on these rules: • No interaction by the user on the site for 1 hour Has added more than $30 worth of products to the basket • Has not completed a transaction You use Google Cloud Dataflow to process the data and decide if a message should be sent. How should you design the pipeline?

  1. Use a fixed-time window with a duration of 60 minutes.
  2. Use a sliding time window with a duration of 60 minutes.
  3. Use a session window with a gap time duration of 60 minutes.
  4. Use a global window with a time based trigger with a delay of 60 minutes.
Show answer and explanation

Correct answer: C. Use a session window with a gap time duration of 60 minutes.

A session window with a gap time duration of 60 minutes is the correct choice because it groups events based on user activity patterns. When a user has no interaction for 60 minutes (the gap duration), the session closes, triggering the abandonment logic. This naturally captures the requirement of no interaction for 1 hour. Session windows are designed for exactly this type of user behavior analysis where you need to detect inactivity periods and trigger actions when gaps occur.

Why the other options are wrong

  • A. Fixed windows emit results at fixed intervals regardless of user activity, missing the inactivity detection requirement.
  • B. Sliding windows would continuously overlap and re-evaluate, not specifically detecting a 60-minute gap in activity.
  • D. Global windows do not partition data by time and would not properly handle the 60-minute inactivity requirement.

Question 3

Your company handles data processing for a number of different clients. Each client prefers to use their own suite of analytics tools, with some allowing direct query access via Google BigQuery. You need to secure the data so that clients cannot see each other's data. You want to ensure appropriate access to the data. Which three steps should you take? (Choose three.)

  1. Load data into different partitions.
  2. Load data into a different dataset for each client.
  3. Put each client's BigQuery dataset into a different table.
  4. Restrict a client's dataset to approved users.
  5. Only allow a service account to access the datasets.
  6. Use the appropriate identity and access management (IAM) roles for each client's users.
Show answer and explanation

Correct answer: B, D, F. Load data into a different dataset for each client; Restrict a client's dataset to approved users; Use the appropriate identity and access management (IAM) roles for each client's users.

Load data into a different dataset for each client (B) provides logical separation, ensuring clients cannot see each other's data at the dataset level. Restrict a client's dataset to approved users (D) enforces access control so only authorized personnel from each client organization can access their data. Use appropriate IAM roles for each client's users (F) implements fine-grained permission management, assigning roles that match client responsibilities. Together, these three steps create a secure multi-tenant architecture with strong data isolation and access governance.

Why the other options are wrong

  • A. Partitions organize data within a single table and do not provide isolation between clients.
  • C. This mixes logical organization concepts; datasets already provide separation without needing multiple tables per client.
  • E. Service accounts are for applications, not users, and do not address client-specific access control needs.

A PDE attempt costs US$200. This pack is US$39, paid once.

What makes the PDE hard

Every question on the PDE is a storage-and-processing decision wearing a business scenario as a disguise: a company with specific latency, cost and consistency requirements, and four Google services that all technically hold data.

BigQuery versus Bigtable versus Spanner versus Firestore is the exam's favourite fork, followed closely by Dataflow windowing and late-data handling for streaming pipelines, Pub/Sub delivery semantics, and when Dataproc exists purely because the scenario mentions existing Hadoop jobs.

It is two hours for only 40 to 50 questions, fewer than most Google professional exams, which means each one carries more weight and the scenarios are longer. IAM, encryption, DLP and a layer of Vertex AI questions round out the paper. This pack will have 349 practice questions mapped to the PDE exam objectives, covering the service-selection and pipeline scenarios Google rotates through.

About the exam

The Professional Data Engineer certifies designing, building, securing, and operationalising data processing systems on Google Cloud. Google recommends three or more years of industry experience including one or more year on Google Cloud. It is valid for two years.
