SECTION 1: FOUNDATIONAL CONCEPTS (14 Questions)
Competency Focus: C724 Competencies 1.1-1.4 – Define IS components, distinguish
data types, describe system development life-cycle phases, identify strategic role of IS.
Q1: A mid-size retailer asks the CIO to explain the difference between the systems that
run daily sales and the system that predicts next-quarter revenue. Which statement best
captures the distinction?
A. Both are operational systems that use real-time data.
B. The sales system is on-line transaction processing (OLTP); the forecast system is
on-line analytical processing (OLAP).
C. OLTP and OLAP are simply two names for the same enterprise database.
D. Forecasting systems never use historical data; they stream live sensor feeds only.
Correct Answer: B
Rationale: Competency 1.2 – Distinguish operational vs. analytical systems. OLTP
captures, inserts, updates routine transactions in real time (sales); OLAP queries large
volumes of historical data for decision support (revenue forecast). Distractors: A) blurs
the two worlds; C) ignores structural differences; D) is factually wrong.
,Q2 (Select all that apply): Which items are characteristics of structured data? (Select all
that apply.)
A. Resides in fixed fields of a record or file
B. Conforms to a pre-defined data model
C. Typically queried with SQL
D. Includes free-text clinician notes
E. Can be stored in a relational DBMS
Correct Answer: A, B, C, E
Rationale: Competency 1.2 – Differentiate data types. Structured data is organized,
labelled, and searchable (A,B,C,E). Free-text notes (D) are unstructured and require NLP
for analysis.
Q3: During which phase of the Systems Development Life Cycle (SDLC) would a project
team construct entity-relationship diagrams and define field constraints?
A. Implementation
B. Design
C. Testing
D. Maintenance
Correct Answer: B
, Rationale: Competency 1.3 – Outline SDLC phases. Design translates requirements into
blueprints: DB schemas, E-R diagrams, UI mock-ups. Implementation writes code;
Testing validates; Maintenance performs post-go-live fixes.
Q4: The strategic "resource-based view" in IS management argues that a firm should
invest in technologies that are:
A. Common across the industry
B. Rare, valuable, non-substitutable and hard to imitate
C. Open-source to minimise cost
D. Popular with competitors
Correct Answer: B
Rationale: Competency 1.4 – Explain strategic IS role. RBV posits sustainable
advantage comes from resources meeting VRIN criteria (Barney). Generic or easily
copied systems (A,C,D) yield no edge.
SECTION 2: APPLICATION & ANALYSIS (35 Questions)
Competency Focus: C724 Competencies 2.1-3.5 – Apply DB concepts, analyse BI value,
evaluate enterprise systems, design basic networks, justify security controls.
Q5: A hospital’s relational database contains the functional dependency:
Patient_ID → Patient_Name, Blood_Type
Which anomaly will occur if the hospital allows duplicate Patient_ID values to be
entered for two different patients?
