2010 Final Examination Paper
(3 points each from 1 to 25)
1,In order to deliver the system on time, the development team implemented a straightforward,
brute force algorithm(蛮力算法) in the system. This algorithm is sufficient for the current needs
But when the volume of business increases，it doesn’t meet the performance requirements.
This situation would be an example of:
a. An exception
b. An error
c. A fault
d. A failure
2,One of the outside systems has defects in its own software, and sometimes sends data to your
system in which some of the data are not in the correct format. When this occurs your system
alerts the Administrators and none of the data from this outside system is updated.
This situation would be an example of:
a. An exception
b. An error
c. A fault
d. A failure
3,Which are NOT valid choices and rationales according to V Model（one kind of Software
Process Models）？
a.Uses unit testing to verify program design;
b.Uses integration testing to verify architectural (system) design;
c.Uses system testing to validate the requirements;
d.Uses acceptance testing to validate the requirements;
4,The Manifesto for Agile Software Development:
“We are uncovering better ways of developing software by doing it and helping others do it.
Through this work we have come to value:
 Individuals and interactions over processes and tools
 Working software over comprehensive documentation
 Customer collaboration over contract negotiation
 Responding to change over following a plan
That is, while there is value in the items on the right, we value the items on the left more.”
Which are NOT valid choices and rationales according to the Manifesto for Agile Software
Development?
a.Emphasis on flexibility in producing software quickly and capably;
b.If we choose Agile Software Development proccess,never need to write documents ;
c.Concentrate on responding to change rather than on creating a plan and then following it;
d.Develops software iteratively with a heavy emphasis on construction activities

5,IBM Rational Unified Process® (RUP®) is a comprehensive process framework that provides
industry-tested practices for software and systems delivery and implementation and for effective
project management.Which are valid choices and rationales according to RUP?
a.Views software development as manufacturing process rather than as creative process
b.There is no iterative activities that lead to creating a final product
c.Provides no guidance how to handle changes to products and activities during development
(assumes requirements can be frozen)
d.Driven by use case to develop Iteratively and continuously verify quality
To build a schedule, the critical path method is used. The activity graph (shown below) is used to
depict the dependencies among the activities and milestones of the project. The nodes of the graph
represent the milestones of the project. The edges linking the nodes represent the activities. The
numbers adjacent to the edges represent the number of days required for the activity. For example,
it will take 5 days to complete the activity starting at milestone A and ending in milestone C. Use
this activity graph to answer the following question 6 and 7:
6.What is the length of the critical path from milestone A to milestone K?
a. 28
b. 32
c. 33
d. 37
7.What is the slack time for the activity starting at milestone F?
a. 4
b. 5
c. 16
d. 21

improve

⑤ To solicit feedback from potential users about what functionality is missing
⑥ Determine whether the customer's problem has a feasible solution
⑦ Assist in exploring options for otimizing quality requirements

14,Which is NOT valid choice and rationale about some common types of architectural views?
a.The decomposition view portrays the system as programmable units,this view is likely to be
hierarchical
b.The dependencies view shows dependencies among software units,This view is useful in project
planning,Also useful for assessing the impact of making a design change to some software unit
c.The implementation view shows the runtime structure of a system in terms of its components
and connectors
d.The deployment view maps runtime entities, such as components and connectors, onto computer
resources, such as processors, data stores, and communication networks
15,Which belongs to Publish-Subscribe Architectural Style?
a.Observer Pattern
b.Strategy Pattern
c.PPLive Streaming Media System
d.Expert System
16,Which is NOT valid choice and rationale about Coupling?
a.Two or more components share the same global variables,that is Common Coupling
b.When one module passes parameters or a return code to control the behavior of another
module,that is Control Coupling
c.when complex data structures are passed between modules,that is Stamp coupling
d.when only data values are passed between modules,that is Stamp coupling
17,Which is NOT valid choice and rationale about the figure(Meta-model of OO constructs)
below?
a.The interface is a kind of type definition,so it doesn't need memory in run-time,but it usaully
appears in header files.
b.The object is the run-time structure of an OO system,so it need memory to store its information
in run-time,and it is as an independent component in source files.
c.The class is code module,so it doesn't need memory in run-time,but it usaully appears in source
files.An object's implementation details are encpsulated in its class definition.
d.The instance variable is program variable whose value is reference/pointer to object,so it need
memory in run-time.
