1. Which of the following measures the amount of data that might be potentially lost as aresult of a system failure? a. recovery time objective (RTO) b. recovery point objective (RPO) c. disaster recovery plan (DRP)d. business continuity plan (BCP) |
b. recovery point objective (RPO) (Correct. The RPO measures the time between the lastdata backup and the occurrence of a problem.) |
|

2. Pre-numbering of all source documents is a mitigating control to preserve processing integrityat what stage of the process? a. input b. processing c. output |
a. input [Correct. Prenumbering improves control by making it possible to verify that nodocuments are missing.] |
|
|
3. Automated controls supplement manual safeguards in checking source documents forreasonableness and propriety. Which of the following is not a data entry control? a. a sign check b. a range check c. a validity check d. a stability check |
d. a stability check [Correct.] |
|
|
4. A reasonableness test checks the validity of the logical relationship between two dataitems. It is an application control that verifies that an account number entered in a transactionrecord matches an account number in the related master file. a. True b. False |
a. True [Correct. Reasonable test is an edit check of the logical correctness of relationshipsamong data items.] |
|
|
5. Which of the following statements is true? a. Incremental daily backups are faster toperform than differential daily backups,but restoration is slower and morecomplex. b. Incremental daily backups are fasterto perform than differential dailybackups, and restoration is faster andsimpler. c. Differential daily backups are faster toperform than incremental daily backups,but restoration is slower and morecomplex. d. Differential daily backups are fasterto perform than incremental dailybackups, and restoration is faster andsimpler. |
a. Incremental daily backups are faster to perform than differential daily backups, butrestoration is slower and more complex. (Correct.) |
|
|
6. A transposition error results when numbers of two adjacent columns are inadvertentlyexchanged (for example, 64 is written instead of 46). It can be mitigated with a. input controls. b. processing controls. c. output controls. |
b. processing controls. [Correct. Processing controls ensure that data is processedcorrectly.] |
|
|
7. Which of the following is an example of the kind of batch total called a hash total? a. the sum of the purchase amount fieldin a set of purchase orders b. the sum of the purchase order numberfield in a set of purchase orders c. the number o f completed documentsin a set of purchase orders d. all of the above |
b. the sum of the purchase order number field in a set of purchase orders (Correct. Thesum of purchase order numbers has no intrinsic meaning.) |
|
|
8. Which of the following statements is true? a. Virtualization significantly reducesRTO for hardware problems. b. Cloud computing reduces the risk thata single catastrophe from either a naturaldisaster or terrorist attack wouldresult in significant downtime and lossof availability. c. Backups still need to be made whenusing either virtualization or cloudcomputing. d. All of the above are true. |
d. All of the above are true. (Correct.) |
|
|
9. What is the name of the basic option for replacing IT infrastructure that is an empty building,prewired for necessary telephone and Internet access, plus a contract with one ormore vendors to provide all necessary equipment within a specified period of time? a. A hot site. b. A cold site. c. A switch site. |
b. A cold site. [Correct. A disaster recovery option that relies on access to an alternativefacility that is prewired for necessary telephone and Internet access.] |
|
|
10. Organizations also need to implement controls designed to minimize the risk of data transmissionerrors. When data is transmitted, the sending device can calculate a hash of the file, called a a. parity bit. b. parity checking. c. check sum. |
c. check sums. [Correct. A data transmission control that uses a hash of a file to verifyaccuracy.] |
