250 Practice Questions with Rationales
EXAM COVERAGE OVERVIEW (10 Key Points)
1. AIS Fundamentals – An AIS consists of people, procedures, data, software, and IT
infrastructure to collect, record, process, store, and communicate information for
decision-making . Data collection is critical because errors at this stage propagate
through the entire system .
2. Useful Information Characteristics – Useful information has five
characteristics: relevance, timeliness, accuracy, completeness, and summarization . Old
information wastes resources; inaccurate information leads to materially wrong
decisions; excessive detail overwhelms decision-makers .
3. AIS Subsystems – The Transaction Processing System (TPS) captures operational
transactions . The Management Reporting System (MRS) provides variance reports and
internal decision-making information . The Financial Reporting System (FRS) produces
external reports like the comparative balance sheet .
4. Data Management – The flat-file approach causes problems: data redundancy, data
storage inefficiency, difficult updating, and currency issues . The database
approach solves task-data independence problems. The closed database
architecture maintains data in distinct, separate, independent applications .
5. System Flowcharts – A system flowchart shows physical relationships among
organizational departments, processes, and files. The inverted triangle represents
temporary files: "N" = numeric filing system, "C" = chronological filing system.
The bucket symbol represents a clerk's manual tasks .
6. Internal Controls & Risk – Primary revenue cycle risk: inaccurately recording sales and
cash receipts. Greatest misappropriation risk: accounts payable. A compensating control
for customer payments is supervision. Internal control weakness: paychecks distributed
by employees' immediate supervisor .

7. Transaction Cycles – The customer purchase order triggers the revenue cycle . Accounts
payable is least involved in the revenue cycle. The sales invoice bills the customer . The
three-way match reconciles quantities ordered with quantities received .
8. Data & File Types – The general ledger master file contains balances for each chart of
accounts account . The master file stores account data updated by transactions.
A material requirements list shows vendor shipments and expected receipts for an
order .
9. ERP & Data Warehousing – The objective of an ERP is to integrate key organizational
processes . A data mart is a warehouse created for a single function or department . Big
data is characterized by volume, velocity, and variety of data . Prescriptive analytics tells
users what actions to take .
10. Documentation & Security – Documentation tools include data flow diagrams,
document flowcharts, system flowcharts, and program flowcharts. Encryption converts
cleartext to ciphertext . A digital signature uses the sender's private key . Continuous
auditing enables reviewing transactions at frequent intervals .

record, process, store, and communicate information for decision-making . It serves not just
financial reporting but operational decision-making across the organization.
2. A manager receives a report that contains detailed transaction data but lacks any summary
information about performance against budget. Which characteristic of useful information is
missing?
A) Relevance
B) Timeliness
C) Completeness
D) Summarization
Correct Answer: D
Rationale: Useful information requires summarization to be valuable . The manager is
overwhelmed by detail without a summary that highlights key insights. Without summarization,
the decision-maker is overwhelmed by excessive detail and cannot extract meaningful
conclusions .
3. An office manager receives a marketing fax: "Our company is having a promotion this
month for all our main products. Please call for more information." Which characteristic of
useful information is missing?
A) Relevance
B) Timeliness
C) Accuracy
D) Completeness
, Page 4 of 103
Correct Answer: D
Rationale: The information is incomplete because it lacks specific details about which products
are on promotion, discount amounts, and terms of the offer . The recipient cannot make an
informed decision without complete information.
4. An accounting report contains data that is three months old when delivered to
management. What is the likely impact on decision-making?
A) The decision-maker will have more time to analyze the information
B) The decision-maker will waste resources analyzing outdated information
C) The information will be more accurate than current data
D) The decision-maker will receive materially wrong information
Correct Answer: B
Rationale: If information is old, the decision-maker wastes resources analyzing outdated
information that no longer reflects current conditions . Timeliness is a critical characteristic of
useful information.
5. Which of the following is NOT a characteristic of useful information in an AIS?
A) Relevance
B) Timeliness
C) Complexity
D) Accuracy
Correct Answer: C
Rationale: The five characteristics of useful information
