Multiple Choice

Q. 

Which of these is not a method for ensuring a program is robust?

• Keeping passwords safe

• Data Sanitisation

• Authentication

• Data Validation

Multiple Choice

 

What does a range check do?

• Checks data across a range of numbers

• Checks the data is within an acceptable range

• Where three types of data are used

• Checks that the data is in the correct format

Multiple Choice

What is the difference between Data Validation and Input Sanitisation?

• Nothing, they are the same?

• Data Validation checks the data is reasonable and Sanitisation removes unexpected or unrequired data

• Data Validation checks the data is correct and Sanitisation removes data that contains errors

• Sanitisation checks the data is correct and Validation removes invalid

• Calculating answers from formula

Multiple Choice

A user enters in extra data attempting to access the system, which method would identify this issue?

• Data Validation

• Input Sanitisation

• Input Check

• Format Check

Multiple Choice

What is a defensive programming design?

• Making your code / program error free

• Creating code that is easy to use and understand

• A method of ensuring that your code is not misused

• Code where the data is validated

Multiple Choice

 

Which of these is not a method for authenticating a user?

• Password

• Password and Username

• Finger print scanner

• Encryption

Multiple Choice

 

Which one of these is not a method for planning for misuse?

• Limiting the number of login attempts

• Requesting a password and username

• Authentication

• Not validating the data entry

Multiple Choice

What is data validation?

• Checking that the data entered is wrong

• Checking that the data entered is correct

• Checking that the data entered is sensible or reasonable

Multiple Choice

What is maintainability?

• Checking programs work

• Updating Code so that it is compatible with current requirements

• Testing a program for errors

• Training staff to use the program correctly

Multiple Choice

Which of these IS NOT an example of validation.

• Mr Jones

• Sarah

• Sarah Jones

• Mrs Jones

Multiple Choice

 

A user attempts to enter in an incorrect password, what method would identify this issues?

• Data Validation

• Authentication

• Program Comments

• Indentation

Multiple Choice

Why is code indented?

• To group together a function

• The code does not use a { syntax and indentation is used instead

• To make the code easier to read

• All of the above

Multiple Choice

When should comments be used within a program?

• To help describe what code and structures are expected to do

• To remind the developer when lunch is

• Every line, so that you know exactly what is happening

• To add random jokes to the code to make it interesting

Multiple Choice

What is a subroutine?

• Subroutines are small blocks of code in a modular program designed to perform a particular task

• Sequence, selection and iteration

• A programming construct that determines the order in which data is stored

• POSITIVE or NEGATIVE
