Question: What type of database is Cloud SQL?
- Non-relational database
- Warehouse database
- Object database
- Relational database
Explanation
Cloud SQL is a fully managed database service for familiar SQL engines such as MySQL, PostgreSQL, and SQL Server. These engines use structured tables, schemas, and SQL-based querying. Google Cloud handles routine administration tasks such as backups, maintenance, and updates. This makes Cloud SQL appropriate for applications that need managed SQL database compatibility.
Why the other options are incorrect
Non-relational database describes services such as Cloud Firestore or Cloud Bigtable, not Cloud SQL.
Warehouse database describes analytics storage such as BigQuery, not Cloud SQL.
Object database does not match the managed SQL engine model provided by Cloud SQL.
