- A
Compute Engine with a self-managed MySQL installation.
Why wrong: Self-managed MySQL on Compute Engine requires the team to handle patching, backups, HA configuration, and monitoring — exactly what the question says they want to avoid.
- B
Cloud SQL
Cloud SQL is a fully managed MySQL/PostgreSQL/SQL Server service. Google handles all infrastructure: patching, backups, HA with automatic failover, and monitoring.
- C
Cloud Bigtable
Why wrong: Cloud Bigtable is a NoSQL key-value/column-family database optimized for high-throughput workloads. It doesn't support SQL, relational schemas, or ACID transactions.
- D
Cloud Storage
Why wrong: Cloud Storage is an object storage service for files (images, backups, datasets). It cannot serve as a relational database with SQL query capabilities.
Quick Answer
The answer is Cloud SQL, the fully managed relational database service on Google Cloud that supports MySQL, PostgreSQL, and SQL Server. This is the correct choice because Cloud SQL handles all administrative tasks automatically, including backups, patching, and high availability through regional failover replicas, so the development team never needs to manage the underlying database server. On the Google Cloud Digital Leader exam, this question tests your understanding of managed services versus self-managed options like Compute Engine; a common trap is confusing Cloud SQL with Cloud Spanner, but remember that Cloud SQL is for traditional relational databases with automatic backups, while Spanner is for globally distributed, horizontally scalable workloads. A useful memory tip is to think of Cloud SQL as “SQL without the server hassle”—it’s the go-to service when the requirement explicitly mentions automatic backups and patching for MySQL or PostgreSQL.
Cloud Digital Leader Practice Question: Google Cloud products, services, and solutions
This GCDL practice question tests your understanding of google cloud products, services, and solutions. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A development team needs a managed relational database (MySQL or PostgreSQL) for their web application. They want automatic backups, patching, and high availability without managing a database server. Which Google Cloud service provides this?

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Cloud SQL
Cloud SQL is a fully managed relational database service for MySQL, PostgreSQL, and SQL Server. It handles automated backups, patching, and high availability (via regional failover replicas) without requiring the user to manage the underlying database server, directly matching the team's requirements.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Google Cloud often tests the distinction between managed and unmanaged services, and the trap here is that candidates may confuse Cloud SQL with Compute Engine self-managed setups, overlooking the 'without managing a database server' requirement.
Detailed technical explanation
How to think about this question
Cloud SQL provides automated backups using point-in-time recovery (PITR) with binary logging, and high availability is achieved through a regional persistent disk and a standby instance in a different zone within the same region, using synchronous replication. Under the hood, Cloud SQL uses a proxy agent for secure connections and automatically applies database patches during maintenance windows, with configurable maintenance timing to minimize disruption.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
