質問 1：
A car manufacturer is updating its airbag deployment system for its family cars. It has increased the number of airbags from four to nine.
This has necessitated an upgrade to the airbag control software (ACS) to allow deployment of the extra airbags where appropriate.
The car manufacturer receives information from on-board sensors. From this, it calculates the amount of deployment needed (minimal, medium and full), and from which airbag(s). For this upgrade, it will receive information from extra sensors to be used in its calculations.
The car manufacturer employs its own in-house software development team. It uses the V model for its software development. There are four stages of testing, from unit through to factory acceptance testing. The development team is made up of project, programming and test managers. The programmers use object-oriented methods for development. The car manufacturer wishes to be first to market with the extra airbags, which will allow it to increase the safety ratings for its family cars, thereby increasing sales in a very competitive market. Which of the following are risks associated with the use of the V model for this upgrade?
I. The sensors may not be responsive enough in impacts.
II. The manufacturer may not be able to process the information received from the sensors quickly enough.
III. The time required to create the high- and low-level designs may mean that insufficient time can be spent on system testing.
IV. The system may fail factory acceptance testing, necessitating costly rework.
A. III and IV
B. II and III
C. I and IV
D. I and II
正解：A

質問 2：
Use the following code; x=1 y=2 z=3 If (x = = 2) { print "Hi There !"; } else { print "Good bye"; } z=x + y; if (z ==4) { print "Welcome Back!"; } else { print "Thank you"; } How many test cases at minimum are required to test branch / decision coverage?
A. 2
B. 3
C. 4
D. 1
正解：A

質問 3：
A software company developed a software application for a Life Insurance Company. The testers of the software company were given the release to test. The software application calculates the annual life insurance cost based on customers' age. Life insurance cost is as follows per year; # Age 18 or less: US $ 300 # Age over 18 or less than 70: US $ 500 # Person has to be at least 1 year old to purchase insurance If a customer enters any other age, the software prints an error message. The Application accepts only positive integer values (no decimals). Given above scenario, how many valid test cases at minimum can you derive using equivalence partitioning?
A. 2
B. 3
C. 4
D. 5
正解：A

質問 4：
Select the correct pair;
I. "Unexpected occurrence that requires a further investigation"
II. "Recognition of failure caused by a defect"
III. Requires a change to the work item a) Incident b) Defect c) Bug d) Failure
A. I-a,II-d,III-b
B. I-a,II-a,III-b
C. I-b,II-c,III-d
D. I-c,II-d,III-b
正解：B

質問 5：
A development house (DH) uses the V model for its projects. It delivers systems to the energy industry. In response to consumer demands, DH has been asked to create an online system for consumers to switch energy suppliers easily. There are already offerings in the marketplace for this service, but DH thinks it can provide a service which is easier to use. It will request more detailed information on homes and occupant lifestyles in order to accurately predict likely bills per quarter, and will update users if a cheaper tariff becomes available. For this new service, the specifications have been defined, code has been created, and system testing is about to start. Which of the following could form part of the entry criteria into system testing?
I. 100 per cent decision coverage of all tariff calculations.
II. 100 per cent functional specification coverage of all household types.
III. Outstanding defects at integration testing highlighted.
IV. Test summary report for system testing produced.
V. Business requirements signed off.
A. II, III and IV
B. I and III
C. I, III and IV
D. I, II and III
正解：B

質問 6：
The main Objective of Test Analysis and Design phase is to;
A. Design and create the test environment
B. Create test strategy and test plan
C. Archive test results, logs and reports in the configuration management system
D. Identify test conditions and create test cases
正解：D

質問 7：
Which of the statement are true about risk based testing;
I. All risks have equal weights / concerns.
II. The level of risk is influenced by likelihood of the risk and impact of the risk.
III. All risks must be mitigated.
IV. Main developer quitting, during the coding phase of the project can be a project risk.
A. I and II true
B. I and III true
C. III and IV true
D. II and IV true
正解：A

質問 8：
Software Testers in a software development company installed the new release on test systems and started the testing phase. Testers verified the new functionality, performed necessary security testing and completed planned regression tests. During the last week of testing, testers noticed that the memory utilization was more than 95% on two of the test servers (out of 4 servers). This behavior was not observed during the first weeks of the testing phase. As a test analyst, what would you do?
A. Create a defect report and reboot the system to correct the memory problem.
B. Ignore the problem because other two servers are okay (memory utilization is normal)
C. Reboot the system so that memory utilization will come back to normal. Not report it as a problem.
D. Report the problem to the developer immediately and create a defect report because it could be a problem related to memory leak.
正解：D
