Your organization has a security policy to ensure that all Cloud SQL for PostgreSQL databases are secure. You want to protect sensitive data by using a key that meets specific locality or residency requirements. Your organization needs to control the key's lifecycle activities. You need to ensure that data is encrypted at rest and in transit. What should you do?
Correct Answer:
B

Your team is building a new inventory management application that will require read and write database instances in multiple Google Cloud regions around the globe. Your database solution requires 99.99% availability and global transactional consistency. You need a fully managed backend relational database to store inventory changes. What should you do?
Correct Answer:
D
Explanation
Spanner covers the SLA
You are configuring the networking of a Cloud SQL instance. The only application that connects to this database resides on a Compute Engine VM in the same project as the Cloud SQL instance. The VM and the Cloud SQL instance both use the same VPC network, and both have an external (public) IP address and an internal (private) IP address. You want to improve network security. What should you do?
Correct Answer:
D
Explanation
It is always more secure to use an internal IP, so removing them doesn't make sense. Eliminate A. You can use Private Google Access when VM instances only have internal IP addresses, so disabling the internal IPs and use Private Google Access doesn't make sense. Eliminate B. Specifying an authorized network when they're on the same subnet doesn't make sense. Eliminate C. A way to improve network security would be to disable external IPs since they're not needed.
Your customer is running a MySQL database on-premises with read replicas. The nightly incremental backups are expensive and add maintenance overhead. You want to follow Google-recommended practices to migrate the database to Google Cloud, and you need to ensure minimal downtime. What should you do?
Correct Answer:
D
Your organization is running a low-latency reporting application on Microsoft SQL Server. In addition to the database engine, you are using SQL Server Analysis Services (SSAS), SQL Server Reporting Services (SSRS), and SQL Server Integration Services (SSIS) in your on-premises environment. You want to migrate your Microsoft SQL Server database instances to Google Cloud. You need to ensure minimal disruption to the existing architecture during migration. What should you do?
Correct Answer:
C
You finished migrating an on-premises MySQL database to Cloud SQL. You want to ensure that the daily export of a table, which was previously a cron job running on the database server, continues. You want the solution to minimize cost and operations overhead. What should you do?
Correct Answer:
A
You are setting up a Bare Metal Solution environment. You need to update the operating system to the latest version. You need to connect the Bare Metal Solution environment to the internet so you can receive software updates. What should you do?
Correct Answer:
C
Explanation
https://cloud.google.com/bare-metal/docs/bms-setup?hl=en#bms-access-internet-vm-nat The docs specifically says 'Setting up a NAT gateway on a Compute Engine VM' is the way to give BMS internet access.

FAQ
Professional-Cloud-Database-Engineer Exam FAQ
Common questions about the exam itself
What prior experience is needed before attempting the Professional Cloud Database Engineer exam?
Google recommends 5 or more years of overall database and IT experience, with at least 2 years of hands-on work with Google Cloud database solutions. This ensures you have the depth to handle both design decisions and operational management across multiple database engines and deployment models.
How difficult is the Professional Cloud Database Engineer exam compared to other Google Cloud certifications?
This is a Professional-level exam requiring deep understanding of relational and NoSQL databases, multi-region architectures, and operational excellence. It demands more than console familiarity - you need to architect solutions, troubleshoot under pressure, and justify design choices with business and technical tradeoffs.
Which domain of the Professional Cloud Database Engineer exam do candidates typically find most challenging?
Migration strategies tend to be the toughest area because they combine planning (zero downtime approaches), technical execution (reverse replication, schema conversion), and fallback design. You need to balance speed against risk and select tools like Database Migration Service correctly for different scenarios.
How long should I prepare for the Professional Cloud Database Engineer exam?
Most candidates with the recommended background need 2 to 4 months of focused study and hands-on lab work. Adjust based on your gap - if you lack multi-region or disaster recovery experience, add time for practical setup and testing of high availability failover.
What happens on exam day for the Professional Cloud Database Engineer certification?
You sit for a proctored exam lasting 240 minutes through either Pearson VUE's online OnVUE platform from home or at a physical testing centre. The exam combines multiple-choice and scenario-based questions that test both conceptual knowledge and decision-making through realistic Google Cloud database challenges.
Can I retake the Professional Cloud Database Engineer exam if I fail, and what are the costs?
Yes, you can retake after 14 days if you fail once or twice. After three failures, you must wait 60 days before trying again. Each attempt costs the full USD 200 fee with no discounts, so preparation matters to avoid repeated costs.
How long is the Professional Cloud Database Engineer certification valid for, and what renewal requires?
Google Cloud has not published a specific expiration period for this certification on their official pages. Check the exam guide or contact Google Cloud Certification support directly for current validity terms and renewal requirements.
What job role does the Professional Cloud Database Engineer certification map to?
This certification targets database professionals, cloud architects, and database engineers who design, build, and manage Google Cloud databases for applications. You work on sizing decisions, high availability design, multi-database management, and migration planning alongside application and infrastructure teams.
How does the Professional Cloud Database Engineer exam relate to other Google Cloud certifications?
It is a Professional-level cert that stands independently - no Associate-level prerequisite exists. It pairs well with Professional Cloud Architect (which covers broader infrastructure) and sits alongside other Professional roles like DevOps Engineer, Security Engineer, and Solutions Architect.
What languages can I sit the Professional Cloud Database Engineer exam in?
Google Cloud has not published a language list for this specific exam on their official pages. Most Google Cloud Professional exams offer English at minimum. Contact Pearson VUE or Google Cloud Certification directly to confirm available languages for your region.
