EXAM QUESTIONS AND ANSWERS
Question 1
When designing a management support system, some benefits may be difficult to
express directly in monetary terms. In such cases, these benefits can be linked to
measurable indicators, such as higher sales, to assess their value.
Answer: True
Explanation: Some information-system benefits are intangible and cannot easily be
assigned a direct monetary value. Connecting them to measurable outcomes, such as
improved sales or productivity, makes it easier to evaluate their contribution.
Question 2
Blockchain technology has recently been overtaken by payment services such as Apple
Pay and PayPal.
Answer: False
Explanation: Apple Pay and PayPal are digital payment platforms, whereas blockchain
is an underlying technology with applications extending beyond payments. The two
should therefore not be treated as technologies competing on exactly the same basis.
Question 3
Which nanotechnology-based structure can be designed to transport medication
through the body for applications such as dissolving blood clots?
,A. Nanotubes
B. Nanocapsules
C. Nanowires
D. Nanofibres
Answer: B. Nanocapsules
Explanation: Nanocapsules can be engineered to carry and release therapeutic
substances at targeted locations. This makes them useful in drug-delivery applications,
including approaches aimed at treating blood clots.
Question 4
Which early expert system was developed to identify the molecular structures of
chemical compounds?
A. MYCIN
B. DENDRAL
C. XCON
D. ELIZA
Answer: B. DENDRAL
Explanation: DENDRAL was an important early expert system developed for analysing
chemical information and determining molecular structures. It demonstrated how
specialist knowledge could be incorporated into an artificial-intelligence system.
Question 5
Senior executives using management support systems are generally least willing to
tolerate which of the following?
A. Complex reports
B. Large databases
, C. Slow response times
D. Detailed analysis
Answer: C. Slow response times
Explanation: Executives typically need information quickly to support time-sensitive
decisions. A system that responds slowly can reduce the usefulness of the information
and frustrate its users.
Question 6
Which part of a decision-support system performs analytical operations on information
stored within the system?
A. User interface
B. DSS engine
C. Database
D. Communication network
Answer: B. DSS engine
Explanation: The DSS engine performs the analytical processing required by the
decision-support system. The database primarily stores the information, while the
engine uses that information to support analysis and decision-making.
Question 7
Nanotechnology is based on methods that specifically involve cloud computing.
Answer: False
Explanation: Nanotechnology concerns the manipulation and application of materials
and structures at extremely small scales. Cloud computing is a separate information-
technology concept involving network-based computing resources and services.
