[amp_mcq option1=”consistency check” option2=”Syntax check” option3=”Range check” option4=”All of the above E. None of the above” correct=”option4″]
The correct answer is: D. All of the above
A consistency check is a type of data validation that ensures that the data entered into a system is consistent with other data in the system. For example, a consistency check might ensure that the value entered in a “date of birth” field is consistent with the value entered in a “age” field.
A syntax check is a type of data validation that ensures that the data entered into a system is in the correct format. For example, a syntax check might ensure that the value entered in a “phone number” field is in the correct format (e.g., 123-456-7890).
A range check is a type of data validation that ensures that the data entered into a system is within a specified range. For example, a range check might ensure that the value entered in a “salary” field is within a specified range (e.g., $10,000 – $100,000).
All of these types of checks can be carried out on the input data to a system. However, there are some types of data that cannot be checked using these methods. For example, it is not possible to perform a consistency check on the value entered in a “comment” field, because there is no way to know what the correct value should be. It is also not possible to perform a syntax check on the value entered in a “free text” field, because there is no defined format for this type of data.
In conclusion, all of the types of checks mentioned in the question can be carried out on the input data to a system, but there are some types of data that cannot be checked using these methods.
