2.3_Assessment_Defensive Design and Testing

What is a key consideration in defensive design to prevent unauthorized access?

• Anticipating misuse

• Use of sub programs

• Naming conventions

• Iterative testing

Which of the following is a part of maintainability in programming?

• Authentication

• Input validation

• Commenting

• Iterative testing

What type of testing is performed at the end of the development process?

• Iterative testing

• Final/terminal testing

• Boundary testing

• Invalid testing

Which type of test data is used to check the system's response to unexpected inputs? (select 2)

• Normal

• Boundary

• Invalid

• Erroneous

What is the main purpose of defensive design in programming?

• To make programs run faster

• To ensure programs run correctly under unexpected conditions

• To improve the visual design of programs

• To reduce the cost of program development

When planning for contingencies, what should you consider about user input data?

• The color of the input field

• The format and type of data

• The speed of data entry

• The user's age

What should a program do if a user enters incorrect data, according to defensive design principles?

• Ignore the input and continue

• Display an error message and ask the user to try again

• Automatically correct the input

• Shut down the program

What is the purpose of converting user input to lowercase in the pseudocode example (using .lower() )?

• To ensure the program runs faster

• To prevent syntax errors

• To handle case sensitivity in user input

• To make the output more readable

What is the purpose of authentication in a program?

• To ensure only authorized users can access the program

• To make the program run faster

• To improve the graphics of the program

• To reduce the size of the program

Which of the following is a method of authentication mentioned in the text / book?

• Using a CAPTCHA

• Sending an email with a code

• Asking for a user’s favorite color

• Using a QR code
