Free EDPT (Electronic Data Processing Test) Questions and Answers

Question 1

Which of the following can be utilized in an online computer system to verify that users have the right authorization to carry out a task?

Accepted Answer

Passwords

Answer

Passwords are a fundamental security control used to verify a user's identity and determine their authorization levels within a computer system. By requiring a unique password, the system ensures that only authenticated users can access specific functions or data, thereby controlling who can carry out a task.

Question 2

Data clerks add up the employee gross pay amounts for each batch of payroll transactions for control purposes. Which of the following summaries best sums up the final result?

Accepted Answer

Financial total

Answer

A financial total is a sum of a field that has intrinsic monetary value, such as gross pay, sales amounts, or invoice totals. These totals are used for control purposes to ensure accuracy and completeness of data processing. A hash total, in contrast, sums non-financial fields (like employee IDs) where the total itself has no inherent meaning but is used for error detection.

Question 3

Inadvertently, a customer places an order for part number 1234-8 rather than 1243-8. Which of the subsequent controls would pick up this problem when it was being processed?

Accepted Answer

Check digit

Answer

A check digit is a single digit computed from the other digits in a number and appended to it, primarily used to detect errors during data entry, such as transcription (single digit error) or transposition (swapping two adjacent digits) errors. If '1234-8' is entered instead of '1243-8', a check digit algorithm would likely identify '1234-8' as an invalid number if '8' is not the correct check digit for '1234', thus catching the transposition error.

Question 4

Which of the subsequent controls would stop the condition below? Because he typed ABC, an invalid code, instead of CAB in his department identification code, the employee's paycheck was processed improperly.

Accepted Answer

Table-lookup procedure

Answer

A table-lookup procedure is a control that validates input data by checking if an entered code or value exists in a predefined master file or table of valid entries. If 'ABC' is an invalid department code, a table-lookup would compare it against the list of approved codes and reject it because it does not match any valid entry, preventing improper processing.

Question 5

When master files are kept on what, can the son-father-grandfather backup strategy be used?

Accepted Answer

Both Magnetic disk and Magnetic tape

Answer

The son-father-grandfather backup strategy is a method of rotating backup media to ensure multiple generations of data are preserved. This strategy is applicable to any storage medium capable of holding sequential backups, including both magnetic tape (which is inherently sequential) and magnetic disk (which can be used for sequential backups, even though it also supports direct access). Therefore, master files kept on either magnetic disk or magnetic tape can utilize this robust backup approach.
