Question 1

This determines if characters are of the proper type.

Accepted Answer

A field check ensures that the data entered is of the correct type, such as numeric, alphabetic, or alphanumeric.

Question 2

This tests a numerical amount to ensure that it does not exceed a predetermined value.

Accepted Answer

A limit check tests whether a numerical amount exceeds a predetermined value. A completeness check verifies that all required data fields are completed, a range check ensures that a value falls within an acceptable range, and a sign check verifies that a value has the correct sign (+/-).

Question 3

A ________ ensures input data will fit into the assigned field.

Accepted Answer

A size check ensures that the input data will fit within the allocated field size. A limit check would ensure that the input data falls within predetermined limits, a range check would verify that the input data falls within a specified range, and a validity check would ascertain the data's correctness.

Question 4

This batch processing data entry control sums a field that contains dollar values.

Accepted Answer

The answer of This batch processing data entry control sums...

Question 5

Sonja Greer called the IT Help Desk in a bad mood."I'm trying to open an Excel file,but I get a message that says that the file is locked for editing.Why is this happening to me?" The answer is likely that

Accepted Answer

The message "file locked for editing" suggests that concurrent update controls have been triggered, which means that someone else is currently editing the file or the file was not properly closed previously. It is a common feature in many collaborative tools to prevent multiple users from editing the same file simultaneously and avoid conflicts. Option A is unlikely as there is no evidence of a virus. Option B is possible but unlikely given the language used in the message. Option D is incorrect since the message implies that Sonja is not currently editing the file.

Question 6

This control protects records from errors that occur when two or more users attempt to update the same record simultaneously.

Accepted Answer

Concurrent update controls prevent errors that occur when multiple users attempt to update the same record simultaneously. Cross-footing balance tests ensure that the debits and credits in a financial system balance out. Data conversion controls ensure the accuracy and completeness of data that is converted from one system to another. Recalculation of batch totals is a control used to ensure the completeness and accuracy of batches of data. However, only concurrent update controls address the specific issue of simultaneous updates to the same record.

Question 7

This data entry control compares the ID number in transaction data to a master file to verify that the ID number exists.

Accepted Answer

This control is a validity check, which is designed to ensure that the ID number is a valid piece of data by comparing it to a master file of known valid ID numbers. The other options are not applicable in this scenario. A reasonableness test checks data for logic and consistency, a user review is a manual review of data by a user, and data matching compares multiple data sets to identify similarities or discrepancies.

Question 8

This control ensures that the correct and most current files are being updated.

Accepted Answer

File labels are used to ensure that the correct and most current files are being updated by providing metadata about the file, such as its version or date.

Question 9

This batch processing data entry control sums the number of items in a batch.

Accepted Answer

Record count is the batch processing data entry control sum that calculates the total number of records or items in a batch. Financial total would sum up the monetary values in a batch, hash total would sum up a specific field in a batch, and sequence check would check if all records are in sequence.

Question 10

This determines the correctness of the logical relationship between two data items.

Accepted Answer

Reasonableness test determines if the result of a computation or comparison is logical and makes sense within the context of the problem. It is used to ensure that the output falls within expected boundaries, thus verifying the logical relationship between two data items. The other options listed are all types of data checks, but they do not directly verify the logical relationship between data items.

Question 11

This batch processing data entry control sums a non-financial numeric field.

Accepted Answer

A hash total is a non-financial numeric field that is used to ensure the accurate and complete processing of a batch of data. It involves adding up the values in the field for all the records in the batch, and then using that total as a control sum to verify that the data has been entered correctly. This method is commonly used in batch processing to detect and correct errors in data entry or transmission.

Question 12

What control are file labels an example of?

Accepted Answer

The answer of What control are file labels an example...

Question 13

When I enter a correct customer number,the data entry screen displays the customer name and address.This is an example of

Accepted Answer

This is an example of closed-loop verification, where the system verifies the correctness of the entered data by retrieving information from a database and displays it back to the user. This ensures that the entered data is accurate and complete. Prompting refers to the system providing user prompts or instructions during data entry, preformatting refers to pre-configured templates or formats for data entry, and error checking refers to detecting and correcting input errors.

Question 14

This tests a numerical amount to ensure that it does not exceed a predetermined value nor fall below another predetermined value.

Accepted Answer

A range check ensures that a numerical value falls within a specified range, not exceeding a maximum or falling below a minimum.

Question 15

A computer operator accidentally used the wrong master file when updating a transaction file.As a result,the master file data is now unreadable.Which control could best have prevented this from happening?

Accepted Answer

Internal header labels can help ensure that the correct files are being used by verifying the identity of the file before processing, thus preventing the use of the wrong master file.

Question 16

This determines if all required data items have been entered.

Accepted Answer

A completeness check verifies that all necessary data fields are filled out and that there are no blank entries. It ensures that the user has entered all of the required data, without which the system cannot function properly.

Question 18

The Spontaneous Combustion Rocket Shoppe in downtown Fargo,North Dakota,generates three quarters of its revenue from orders taken over the Internet.The revenue clearing account is debited by the total of cash and credit receipts and credited by the total of storefront and Internet sales.This is an example of a

Accepted Answer

The description matches a zero-balance test, where the goal is to ensure that the total debits (from cash and credit receipts) equal the total credits (from storefront and Internet sales), resulting in a zero balance when subtracting one from the other.

Question 19

Check digit verification is an example of a(n)

Accepted Answer

Check digit verification is an example of an input control because it ensures that data entered into a system is accurate and complete before it is processed. The check digit is calculated based on the other digits in the input and is used to verify that the input is valid. This helps to prevent errors and fraud that could result from incorrect or incomplete data.
