Question 1 of 197

You are developing a new application on a VM that is on your corporate network.

The application will use Java Database Connectivity (JDBC) to connect to Cloud SQL for PostgreSQL.

Your Cloud SQL instance is configured with IP address 192.168.3.48, and SSL is disabled.

You want to ensure that your application can access your database instance without requiring configuration changes to your database.

What should you do?

Show answer

Correct answer: C

The Cloud SQL Auth proxy authenticates with a service account through IAM and encrypts the connection itself, so the application gets an encrypted, identity-based connection to the instance's private IP address without enabling SSL on the database or changing any instance setting. The JDBC connection string simply points at the local proxy endpoint, and the proxy carries the traffic over the corporate network's private connectivity. Connecting straight to the private IP with a database password would send credentials and data in clear text because SSL is disabled, and the public IP options either expose the instance or are unreachable for an instance that only has a private address.

Question 2 of 197

Your digital-native business runs its database workloads on Cloud SQL. Your website must be globally accessible 24/7. You need to prepare your Cloud SQL instance for high availability (HA). You want to follow Google-recommended practices. What should you do? (Choose two.)

Answer choices
Show answer

Correct answers: D, E

To prepare your Cloud SQL instance for high availability, Google recommends enabling point-in-time recovery and scheduling automated backups. Point-in-time recovery allows you to restore your database to a specific point in time, helping you to recover from data loss or corruption. Scheduling automated backups ensures that you have a recent copy of your database available for recovery in case of an outage or other issue. Automated processes reduce the risk of human error and ensure regular, reliable backups, which are essential for maintaining high availability.

Question 3 of 197

Your company wants to move to Google Cloud. Your current data center is closing in six months. You are running a large, highly transactional Oracle application footprint on VMWare. You need to design a solution with minimal disruption to the current architecture and provide ease of migration to Google Cloud. What should you do?

Answer choices
Show answer

Correct answer: A

Migrating applications and Oracle databases to Google Cloud VMware Engine (VMware Engine) is the best approach for minimizing disruption while preserving the current architecture. This solution allows you to lift and shift your existing VMware-based Oracle environment directly to Google Cloud with minimal changes, maintaining the same structure and operational processes. This ensures continuity and makes the migration process simpler and less disruptive compared to other options, which would require significant architectural changes or are not fully supported for Oracle databases.

Question 4 of 197

Your customer has a global chat application that uses a multi-regional Cloud Spanner instance. The application has recently experienced degraded performance after a new version of the application was launched. Your customer asked you for assistance. During initial troubleshooting, you observed high read latency. What should you do?

Answer choices
Show answer

Correct answer: C

To address the issue of high read latency, it is crucial to gather data about read operations. Analyzing the SPANNER_SYS.READ_STATS* tables provides statistics on read operations, including the number of reads, read latency, and any read errors. This information is vital for understanding the root cause of the high read latency and taking appropriate corrective actions. Changing the configuration to single region or using query parameters may not directly address the issue of read latency and may have other unintended consequences.

Question 5 of 197

Your company has PostgreSQL databases on-premises and on Amazon Web Services (AWS). You are planning multiple database migrations to Cloud SQL in an effort to reduce costs and downtime. You want to follow Google-recommended practices and use Google native data migration tools. You also want to closely monitor the migrations as part of the cutover strategy. What should you do?

Answer choices
Show answer

Correct answer: A

For migrating PostgreSQL databases to Cloud SQL while following Google-recommended practices and using Google native data migration tools, the best approach is to use the Database Migration Service. This service is designed for both one-time migrations and change data capture (CDC) style migrations, making it suitable for reducing costs and downtime while allowing close monitoring of the migration process.

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.
