Question 1

A facility that is pre-wired for necessary telecommunications and computer equipment,but doesn't have equipment installed,is known as a

Accepted Answer

A cold site is a facility that is pre-wired and ready for necessary equipment installation, but does not have any equipment on site. It is essentially an empty shell that can be used in case of a disaster or outage to quickly install necessary equipment and get operations back up and running. A hot site, on the other hand, not only has the necessary wiring but is also fully equipped and operational, while remote site and subsidiary location refer to different types of physical locations rather than pre-wiring and equipment readiness.

Question 2

What is the most effective way to ensure information system availability?

Accepted Answer

Maintaining a hot site is the most effective way to ensure information system availability as it involves keeping a duplicate system with all the required data and resources in a fully operational state, which can take over immediately in the event of a primary system failure. This ensures minimal downtime and maximum availability of the system. High bandwidth, cold site, and frequent backups are also important, but they may not be as effective as a hot site in ensuring immediate availability of the system.

Question 3

Which of the following is not a risk associated with the data input process?

Accepted Answer

Data corruption typically occurs during storage or transmission, not during the input process. The input process risks include invalid, incomplete, or inaccurate data, but not corruption, which is generally associated with errors in storing or transmitting data.

Question 4

A facility that contains all the computing equipment the organization needs to perform its essential business activities is known as a

Accepted Answer

A hot site is a fully equipped facility that contains all the computing equipment necessary to perform essential business activities. It is designed to quickly take over operations in the event of a disaster or disruption in the main facility. A cold site is a facility that is not fully equipped and requires additional setup before it can be operational. A remote site is a geographically separate location and not necessarily equipped for computing activities. A subsidiary location is not specifically related to computing equipment.

Question 7

The control that verifies accuracy by comparing two alternative ways of calculating the same total is called

Accepted Answer

The control that verifies accuracy by comparing two alternative ways of calculating the same total is called cross-footing balance test. This control ensures that the total is accurate and has not been tampered with. The other options listed (A, C, and D) are different types of controls that serve other purposes in the data processing system.

Question 8

The control that protects records from errors that occur when two or more users attempt to update the same record simultaneously is called

Accepted Answer

The control that protects records from errors that occur when two or more users attempt to update the same record simultaneously is called concurrent update controls. This control ensures that multiple users can access and update the records concurrently without creating any inconsistency or errors. The other answer choices, such as cross-footing balance test, data conversion controls, and recalculation of batch totals, are not directly related to protecting records from concurrent updates.

Question 9

Which of the following is an example of a turnaround document?

Accepted Answer

A turnaround document is a type of document that is generated by a computer system and then used by a person, who adds some additional information to the document before returning it back to the computer system. In this case, a telephone bill is generated by a computer system and then sent to the customer, who has to fill out the bill and return it with the payment.

Question 10

When opening an Excel file,Sonja received a message saying that the file is locked for editing.This is happening because

Accepted Answer

The message indicates that the file is currently being edited by someone else, and concurrent update controls have locked the file to prevent multiple users from editing it at the same time. It is important to coordinate with the other user(s) to avoid conflicting changes and ensure data integrity.

Question 11

Which of the following is not an objective of a disaster recovery plan?

Accepted Answer

While it is important to establish alternative means of processing information during a disaster, the objective of a disaster recovery plan is not to establish a permanent alternative means. The objective is to minimize the extent of the disruption, damage or loss; resume normal operations as soon as possible; and train employees for emergency operations.

Question 12

Modest Expectations Investment Services (MEIS)allows customers to manage their investments over the Internet.If customers attempt to sell more shares of a stock than they have in their account,an error message is displayed.This is an example of a

Accepted Answer

A reasonableness test checks whether the input data is reasonable or makes sense, such as ensuring that a customer cannot sell more shares than they own.

Question 13

Which of the following statements is true with regards to system availability?

Accepted Answer

Threats to system availability can come in various forms such as hardware and software failures, as well as natural and man-made disasters. Human error can also be a threat to system availability. While proper controls can mitigate risks, they cannot completely eliminate them.

Question 14

Which of the following is an important control to prevent buffet overflow vulnerabilities?

Accepted Answer

Size check is crucial for preventing buffer overflow vulnerabilities as it ensures that the amount of data written to a buffer does not exceed its allocated size, thus preventing overflow.

Question 15

Question 16

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

A header record could best have prevented this from happening because it includes file identification information that can be checked before a file is processed to ensure the correct file is being used.

Question 17

What control are zero balance tests an example of?

Accepted Answer

Zero balance tests are a type of processing control designed to ensure that transactions are processed correctly. For example, they might be used to verify that the total debits equal the total credits in a transaction, ensuring accuracy in data processing.

Question 18

A ________ control entails verifying that the proper number of bits are set to the value 1 in each character received.

Accepted Answer

A parity check involves adding an extra bit to each character to ensure that the total number of bits set to the value 1 is always even or odd, depending on the parity used. This allows for detection of errors such as a single bit being flipped during transmission.

Question 19

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 20

A disaster recovery plan typically does not include

Accepted Answer

A disaster recovery plan is focused on restoring the systems and data in the event of a disaster or disruption. A system upgrade due to operating system software changes is not considered part of a disaster or disruption, but rather a planned change that would be addressed through standard change management processes. The other options listed are all common components of a disaster recovery plan.
