1. In form validation, what does a schema define?

   1. The database structure where data will be stored
   2. The error messages shown to users
   3. The visual layout of form input fields
   4. The set of rules that determine what valid input looks like

2. A developer creates a form with client-side validation but skips server-side validation. What is the most likely security risk?

   1. The website will become unavailable
   2. Attackers can bypass client validation and submit invalid data
   3. Users will see slower form submission times
   4. The form will not work on mobile devices

3. What is Zod?

   1. A validation library that lets you define schemas in code
   2. A programming language for building websites
   3. A visual tool for designing web forms
   4. A type of database that stores user information

4. What is the primary reason for validating form input on the client side?

   1. To completely eliminate the need for server-side validation
   2. To provide immediate feedback to users about input errors
   3. To store user data permanently
   4. To prevent the server from processing any requests

5. Why is server-side validation considered essential for security?

   1. It makes forms work on older web browsers
   2. It ensures the database receives only properly validated data
   3. It allows users to submit forms more quickly
   4. It improves the visual design of web forms

6. If a form has a birthdate field requiring users to be 13 years or older, what does this rule enforce?

   1. Users must submit their birth certificate
   2. Users must be at least 13 years old
   3. Users must be born in the 13th month of a year
   4. Users must provide their exact birth year

7. In form validation, where do error messages typically appear?

   1. In a separate email sent to the user
   2. Next to the specific field that failed validation
   3. Only in the server logs
   4. In a pop-up window that blocks further use

8. How can AI help with form validation?

   1. By designing the visual colors and layout of a form
   2. By sending form data directly to other websites
   3. By writing validation schemas that check input rules
   4. By automatically posting content on social media

9. A web form checks that an email address contains an @ symbol and a domain name. What type of validation is this performing?

   1. Syntax or format validation
   2. Password strength validation
   3. Database validation
   4. Server-side validation only

10. What security problem occurs when a form only validates input in the browser?

    1. The website will crash permanently
    2. The website will load more slowly
    3. Form submissions will be accidentally deleted
    4. Malicious users can bypass validation and submit harmful data

11. Why is it important to check if a username already exists in the database during registration?

    1. To prevent multiple users from having identical usernames
    2. To make the registration process faster
    3. To improve the visual appearance of the user interface
    4. To allow users to change their password more easily

12. If client-side validation accepts invalid input, what additional step must still be performed?

    1. Nothing else is required
    2. Send the data to a third party
    3. Display the error messages again
    4. Reject the input through server-side validation

13. When AI generates a Zod schema for a signup form, what has been created?

    1. An automated email system
    2. A set of code rules defining what input is considered valid
    3. A backup of the user database
    4. A graphical interface for entering data

14. A validation rule requiring passwords to be at least 8 characters is an example of protecting against what?

    1. Weak passwords that are easy to guess
    2. Users who forget their passwords
    3. Incorrect email formatting
    4. Slow internet connections

15. What is the main advantage of using the same validation schema for both client and server validation?

    1. It removes the necessity for any validation
    2. It allows the form to load more quickly
    3. It makes the form work on mobile devices
    4. It creates consistent rules in both locations, reducing gaps attackers could exploit
