Validation and Verification Quiz

What kind of a validation check is shown in the code?

• Length Check

• Range Check

• Presence Check

• Type Check

Answer explanation

The code performs a range check, which verifies if a value falls within a specified minimum and maximum limit. This ensures that the input is valid and meets the required criteria, distinguishing it from other checks.

The process of checking that the data entered is reasonable and within bounds is called

Answer explanation

What is the purpose of verification?

• check that the data entered is correct

• check that the data has been accurately copied from one source to another

• checks that the data entered is within a correct range

• checks that the data entered is of a given data type

Answer explanation

The purpose of verification is to check that the data has been accurately copied from one source to another, ensuring data integrity and accuracy during data transfer.

Identify which validation rule tihs algorihtm uses

• Range check

• Type check

• Format check

• Check digit

Answer explanation

The algorithm uses a range check to ensure that input values fall within a specified range. This validation rule is crucial for maintaining data integrity by preventing out-of-bounds values.

Identify which validation rule tihs algorihtm uses

• Range check

• Presence check

• Format check

• Check digit

Answer explanation

The algorithm uses a presence check, which ensures that required data is provided. This validation rule confirms that necessary fields are not left empty, making it essential for data integrity.
