Question 1

The following state transition diagram describes the functionality involved in a system using fingerprint and password authentication to log onto a system.

How many distinct states of the system are visible in the above diagram?

Answer : C

The state transition diagram provided shows three distinct states:

Waiting for fingerprint

Waiting for PIN

Valid PIN/ask menu selection

Each state represents a different stage in the system's operation, with transitions based on user actions and system responses.

Question 2

A possible risk of introducing test automation is:

Athe tool may not be fit-for-purpose.

Bthe tool may create additional development dependencies.

Cthe tool may not be compatible with the development platform.

Dthe tool will be owned and maintained by developers and replace testers.

Answer : A

One possible risk of introducing test automation is that the selected tool may not be fit-for-purpose. This means that the tool might not meet the specific needs and requirements of the project, leading to inefficiencies and possibly failing to provide the expected benefits. It is crucial to evaluate and select the appropriate tool based on the project's context and objectives. The ISTQB CTFL syllabus highlights the importance of careful tool evaluation and selection to ensure it aligns with the testing goals and the development environment.

Question 3

Which of the following characterizations applies to a test tool used for the analysis of a developer's code prior to its execution?

ATool support for test design and implementation.

BTool support for static testing.

CTool support for test execution and logging.

DTool support for performance measurement and dynamic analysis.

Answer : B

A test tool used for the analysis of a developer's code prior to its execution falls under the category of static testing tools. Static testing involves examining the code and documentation without executing the code. These tools are used to perform static analysis, which helps in identifying potential defects and code quality issues early in the development process. The ISTQB CTFL syllabus specifies that static analysis tools are essential for finding defects that do not manifest themselves during the execution of the program.

Question 4

Which of the following statements is incorrect regarding the involvement of testers in the software development lifecycle (SDLC)?

ATesters should contribute to all activities in the SDLC and participate in design discussions.

BTesters should be involved from the beginning of the SDLC to increase understanding of design decisions and detect defects early.

CTesters should only be involved during the testing phase.

DTesters' involvement is essential; developers find it difficult to be objective.

Answer : C

Involving testers only during the testing phase is incorrect as per the ISTQB CTFL syllabus. Effective involvement of testers is crucial throughout the entire software development lifecycle (SDLC). This includes early stages such as requirement analysis and design, which allows testers to understand the design decisions and detect defects early. Early involvement helps in better understanding the project and ensures that quality is built into the product from the beginning. Furthermore, the ISTQB syllabus emphasizes the importance of testers contributing to all activities in the SDLC, including design discussions, to enhance defect detection and prevention.

Question 5

During iteration planning, a scrum team uses an estimation technique called planning poker to estimate the effort required to deliver a critical user story. In advance of the estimation session, the team agreed on some ground rules to limit the number of poker rounds and save time.

The team agreed on the following:

1. They will use the following progression for estimation: Extra-small, Small, Medium, Large, Extra-large, and Extra-extra-large.

2. If estimation values differ significantly, the highest score will be used for estimation purposes.

The result of the first round of planning poker:

Team Member Estimation

Business Large

Development Extra-extra-large

Testing Extra-extra-large

Which of the following options best represent the team's next actions?

AThe fact that all estimations are high indicate that the user story is not well understood or should be broken down into multiple smaller stories.

BThe pre-agreed rules state that the highest score should be used for estimation, resulting in the user story being categorised as Extra-extra-large.

CSince the business representative is likely to have the most informed view of the requirement, the user story is categorised as a Large.

Dthe team discusses the differences in the estimates and repeats the poker round until an agreemet is reached.

Answer : D

In a planning poker session, if there is a significant difference in the estimations, it indicates that there may be misunderstandings or different perspectives on the complexity of the user story. According to the agile principles, the team should discuss these differences to reach a common understanding. The goal is to ensure that all team members have a shared understanding of the user story's scope and complexity before finalizing the estimate.

Question 6

During which main group of test activity are the following tasks performed?

* Checking test results and logs against specified coverage criteria.

* Assessing the level of component or system quality based on test results and logs.

* Determining whether more tests are needed.

Select the correct answer:

ATest planning.

BTest analysis.

CTest design.

DTest monitoring and control.

Answer : D

The activities of checking test results and logs against specified coverage criteria, assessing the level of component or system quality based on test results and logs, and determining whether more tests are needed fall under the category of test monitoring and control. This phase involves ongoing assessment and adjustment of the test activities to ensure they meet the test objectives and quality goals.

Question 7

Which of the statements correctly describes when a whole team approach may NOT be suitable?

AWhen a high level of test independence may be required.

BWhen acceptance tests need to be created.

CWhen a test automation approach needs to be determined.

DWhen the team dynamics need to be improved.

Answer : A

The whole team approach involves collaboration among all team members, including testers, developers, and business representatives, to achieve quality goals. However, this approach may not be suitable in situations where a high level of test independence is required. Test independence is essential in cases where unbiased testing is critical, such as in regulated environments or where high-risk systems are involved. This is because team members might unintentionally influence each other's work, leading to potential bias in testing outcomes.
