Why should production databases have backups enabled?

In a production environment using Supabase, why is it important to enable automatic backups for your database?

A To improve the speed of database queries during peak hours.

B To reduce the storage costs by deleting old data automatically.

C To ensure data can be restored in case of accidental deletion or corruption.

D To allow multiple users to edit the same data simultaneously without conflicts.

💡 Hint

Think about what happens if data is lost or damaged in production.

Automatic backups protect production data by allowing recovery if data is lost or corrupted. This is critical to avoid downtime and data loss.

❓ security

What is the risk of using default API keys in production?

Supabase provides default API keys when you create a project. What is the main risk of using these default keys in a production environment?

A They can be easily guessed or found, allowing unauthorized access to your database.

B They limit the number of concurrent users to one.

C They automatically expire after 24 hours, causing service interruptions.

D They cause the database to run slower under heavy load.

💡 Hint

Consider what happens if someone else knows your API keys.

Default API keys are publicly known and not secure. Using them in production can let attackers access or modify your data.

Which configuration change improves production performance in Supabase?

To improve performance in a Supabase production environment, which configuration change is most effective?

A Enable connection pooling to reduce database connection overhead.

B Disable SSL to speed up data transfer.

C Increase the frequency of backups to every minute.

D Use the free tier for all production workloads to save costs.

💡 Hint

Think about how database connections affect speed and resource use.

Connection pooling reuses database connections, reducing overhead and improving response times in production.

What happens if environment variables are misconfigured in production?

In Supabase, environment variables store important settings. What is the likely result if these variables are misconfigured in production?

A The application will run faster due to fewer checks on variables.

B The database will automatically fix the variables and continue running.

C Users will be able to access the database without authentication.

D The application may fail to connect to the database or use incorrect credentials.

💡 Hint

Consider what environment variables control in an app.

Misconfigured environment variables can cause connection failures or security issues because the app uses wrong settings.

❓ Architecture

expert

How should you architect Supabase for high availability in production?

To ensure your Supabase production setup is highly available, which architecture approach is best?

A Run a single database instance with daily manual backups.

B Use multiple database replicas with automatic failover and distribute traffic across them.

C Use only the free tier with no replicas to reduce costs.

D Disable all monitoring to improve performance.

💡 Hint

Think about how to keep the service running even if one part fails.

Multiple replicas with failover ensure the database stays available if one instance fails, which is critical for production uptime.
