Given this Flask-SQLAlchemy setup:

app.config['SQLALCHEMY_POOL_SIZE'] = 5
app.config['SQLALCHEMY_MAX_OVERFLOW'] = 10

What is the maximum number of simultaneous database connections allowed?

Pool size is 5 connections kept open. Max overflow allows 10 extra temporary connections.
Step 2: Calculate total max connections
Total max = pool size (5) + max overflow (10) = 15 connections.
Final Answer:
