Question 42
What risk can arise from not having a separate system maintenance function?
A) Improved system performance B) Increased operational costs C) Difficulty in testing and debugging the system D) Fewer security vulnerabilities
Answer: C) Difficulty in testing and debugging the system
Explanation: Without a separate system maintenance function, it can be challenging to interpret, test, and debug systems efficiently.
Question 43
What do filtering rules in a network-level firewall control?
A) The type of data processed by the accounting system B) Access to system resources based on defined criteria C) The allocation of computer memory D) The accuracy of transaction postings
Answer: B) Access to system resources based on defined criteria
Explanation: Filtering rules in a firewall determine which access requests are allowed or denied based on specified criteria.
Question 44
What process describes recording every data value within a system?
A) Data redundancy B) Data recording C) Data backup D) Data completeness
Answer: D) Data completeness
Explanation: Data completeness tests ensure that all required data values are recorded within the system.
Question 45
Why might a medical firm decide to purchase a commercial system rather than continue developing an in-house system?
A) In-house systems are too customizable B) Special-purpose commercial systems are available for the medical field C) Commercial systems are harder to maintain D) Commercial systems are more expensive
Answer: B) Special-purpose commercial systems are available for the medical field
Explanation: Many commercial systems are designed for specific industries, such as medical firms, and may offer more targeted functionality than in-house systems.
Question 46
What is the most effective type of control according to the preventive-detective-corrective (PDC) control model?
A) Corrective B) Preventive C) Detective D) Reconciliation
Answer: B) Preventive
Explanation: Preventive controls are the most effective in the PDC model as they aim to stop undesirable events from occurring in the first place.
Question 47
What type of anomaly occurs when data is accidentally deleted from a table?
A) Update anomaly B) Deletion anomaly C) Insertion anomaly D) Sequence anomaly
Answer: B) Deletion anomaly
Explanation: A deletion anomaly occurs when data is unintentionally deleted, often due to poor database normalization.
Question 48
How many surprise checks must an organization undergo annually to maintain the International Computer Security Association (ICSA) seal?
A) 1 B) 2 C) 3 D) 4
Answer: B) 2
Explanation: Organizations must undergo two surprise checks annually to maintain the ICSA seal, ensuring data security.
Question 49
What function does a system maintenance group perform?
A) Monitoring the flow of information across systems B) Maintaining system documentation and correcting issues C) Approving transactions for payroll processing D) Conducting system audits and reports
Answer: B) Maintaining system documentation and correcting issues
Explanation: A system maintenance group ensures that system documentation is up-to-date and fixes any errors or issues that arise.
Question 50
Which of the following helps detect errors in a production database?
A) Parallel simulation B) Transaction sequencing C) Reconciliation report D) Access test
Answer: A) Parallel simulation
Explanation: Parallel simulation is a method used to detect errors by reprocessing the same transactions that the production application processed to compare results.
