13.01 Server Side Python With A Microframework And The Back End Request Flow - Quiz

Check your understanding

1. In a typical web request flow, what is the primary role of the web server (like nginx or Apache)?

   • Execute Python application code
   • Handle socket connections and serve static files { data-correct }
   • Process database queries
   • Render HTML templates

2. Which Flask decorator is used to define a route that handles both GET and POST requests?

   • @app.route('/path')
   • @app.route('/path', methods=['GET', 'POST']) { data-correct }
   • @app.get_post('/path')
   • @app.method('/path', 'GET,POST')

3. What is the most important security practice when inserting user input into database queries?

   • Validating input length
   • Using parameterized queries { data-correct }
   • Checking input type
   • Escaping special characters

4. What is the primary difference between client-side and server-side input validation?

   • Client-side validation is faster and more secure
   • Server-side validation can be bypassed while client-side cannot
   • Client-side validation improves user experience while server-side ensures security { data-correct }
   • There is no difference between the two approaches

5. In g object?Flask, what is the purpose of the

   • Global configuration settings
   • Application context storage for the current request { data-correct }
   • User session data
   • Database connection pool

6. Which component in the web stack is responsible for converting between HTTP and Python application interfaces?

   • Web server
   • WSGI server { data-correct }
   • Database connector
   • Template engine

7. What is the most likely consequence when a web application’s database becomes temporarily unavailable?

   • The web server will automatically restart
   • Users will receive HTTP 500 errors for database-dependent requests { data-correct }
   • Static files will stop being served
   • The application will switch to a backup database automatically

8. What is the primary purpose of middleware in web frameworks?

   • Handle database connections
   • Process requests before they reach route handlers { data-correct }
   • Render HTML templates
   • Manage static file serving

9. Which Flask function should be used to securely hash passwords?

   • hash()
   • hashlib.md5()
   • generate_password_hash() { data-correct }
   • base64.encode()

10. In the complete path of a web request from browser to database, which component typically comes between the web server and the Flask application?

    • Template engine
    • Database connector
    • WSGI server { data-correct }
    • Load balancer
