QUESTION: 73

An application is subjected to a constant load for an extended period of time as part of a performance test While running this test, the response time of the application steadily slows down, which results in a requirement not being met This slowdown is caused by a memory leak where the application code does not properly release some of the dynamically allocated memory when it is no longer needed.
Which of the following statements is TRUE?

The slowdown is a failure while the memory leak is a defect
The slowdown is a defect while the memory leak is an error.
The slowdown is an error; the memory leak is a defect.
The slowdown is a defect; the memory leak is a failure.

Answer(s): A

Explanation:

In software testing terminology, a failure is an observable deviation of the software from its expected behavior. A defect (or bug) is the cause of the failure in the software's code. In this case, the observed slowdown is the failure, while the underlying memory leak in the application code is the defect causing this failure. This distinction is clearly outlined in the ISTQB CTFL Syllabus v4.0, which differentiates between failures (observable issues) and defects (underlying issues in the code) .

QUESTION: 74

In addition to thorough testing of the requirements specification, a development team aims to involve users as early as possible in the development process, using practices such as prototyping, to ensure that the software systems being developed will meet the users' expectations. This approach is especially useful at mitigating the risks associated with one of the seven testing principles, which one?

Tests wear out
Absence-of-errors fallacy
Working software over comprehensive documentation.
Defects cluster together

Answer(s): B

Explanation:

The absence-of-errors fallacy is the mistaken belief that just because a software system is free of defects, it will meet the user's needs and expectations. Involving users early through practices like prototyping helps ensure that the development team is building the right system that meets user expectations, not just a system that is defect-free. This approach aligns with the testing principle that emphasizes understanding the users' needs and ensuring the system fulfills them. This principle is explained in the ISTQB CTFL Syllabus v4.0 .

QUESTION: 75

Determining the schedule for each testing activity and test milestones for a test project, using activity estimates, available resources, and other constraints is a typical task performed during

Test execution
Test design.
Test analysis.
Test planning

Answer(s): D

Explanation:

Test planning involves defining the overall approach to testing, including scheduling, resources, and milestones. It is during this phase that the detailed schedule for each testing activity is determined based on estimates, resource availability, and constraints. The ISTQB CTFL Syllabus v4.0 outlines that test planning encompasses the creation of test plans and schedules to ensure that testing activities are properly managed and controlled .

QUESTION: 76

A document descnbes the test procedures that have been derived for the identified test sets Among other things, the order in which the test cases in the corresponding test set are to be executed according to the dependencies described by preconditions and postconditions is specified This document is a typical work product produced as part of:

Test design.
Test analysis
Test Implementation.
Test monitoring and control

Answer(s): C

Explanation:

Test implementation involves finalizing the test procedures, including the order of execution of test cases based on their dependencies, preconditions, and postconditions. This phase ensures that all necessary test scripts, test data, and test environments are ready for execution. According to the ISTQB CTFL Syllabus v4.0, test implementation is the phase where detailed test procedures are derived and documented, making it a critical step before actual test execution .
