Google Cloud Certified - Professional Cloud Database Engineer Sample Questions:
Your company is migrating from an on-premises database to a single-region Spanner instance.
The current database supports 40,000 reads each second, and 7,000 writes each second, at 1- KB row sizes at peak. You need to determine the most cost-effective size for the Spanner instance to handle the equivalent current workload. What should you do-
- A. Select a 4-node Spanner instance.
- B. Select a 6-node Spanner instance.
- C. Select a 1-node Spanner instance.
- D. Recommend a multi-region Spanner instance.

You have a non-critical business application running on Google Kubernetes Engine (GKE) in the app-dev VPC. You have created an AlloyDB cluster with Private Service Access (PSA) and no public IP address in the db-dev VPC. You want your application to securely connect to AlloyDB in a cost-effective way. What should you do-
- A. Connect by using the private IP address of the AlloyDB cluster directly from the application.
- B. Connect by using AlloyDB Auth Proxy installed in the GKE cluster.
- C. Install a SOCKS proxy in a VM in the db-dev VPC. Install AlloyDB Auth Proxy in your GKE cluster, and connect to the AlloyDB cluster through the SOCKS server and port.
- D. Set up a high availability VPN between the app-dev and db-dev VPCs. Connect the application directly to AlloyDB.

Your IoT monitoring platform ingests sensor data from 100,000 devices, generating 2 million writes per second during peak hours and 500,000 writes per second during off-peak hours. Each record is 1KB with a row key format: deviceId#timestamp. Your current 12-node Bigtable cluster experiences hotspotting on specific device ranges, with three nodes handling majority ofthe traffic while others remain underutilized. Read queries typically access the last 24 hours of data for specific devices. Storage costs are becoming a concern as you retain two years of historical data (500TB total). You need to optimize performance, eliminate hotspotting, and reduce storage costs while maintaining read latency under 10ms. What should you do-
- A. Split the table by device type, use separate Bigtable instances for different geographic regions, and implement read replicas for query optimization.
- B. Increase cluster size to 20 nodes, implement row key salting with hash prefix, and enable compression on all column families.
- C. Implement row key sting wth hash prefix, configure automsted sealing with an optimal min max threshold setting, and migrate data older than 6 months to Cloud Storage.
- D. Change the row key format to deviceId#timestamp, implement automated scaling with an optimal min max threshold setting based on CPU utilization, and migrate data older than 6 months to Cloud Storage
