최신 ISTQB Certified Tester CTFL4 무료샘플문제 (Q59-Q64):

질문 # 59
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:

A. Test monitoring and control
B. Test analysis
C. Test Implementation.
D. Test design.

정답：C

설명：
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.

질문 # 60
Which of the following issues cannot be identified by static analysis tools?

A. Very low MTBF (Mean Time Between failure)
B. Referencing a variable with an undefined value
C. Security vulnerabilities
D. Potentially endless loops

정답：A

설명：
Static analysis tools are software tools that examine the source code of a program without executing it. They can detect various types of issues, such as syntax errors, coding standards violations, security vulnerabilities, and potential bugs12. However, static analysis tools cannot identify issues that depend on the runtime behavior or performance of the program, such as very low MTBF (Mean Time Between failure)3. MTBF is a measure of the reliability of a system or component. It is calculated by dividing the total operating time by the number of failures. MTBF reflects how often a system or component fails during its expected lifetime. Static analysis tools cannot measure MTBF because they do not run the program or observe its failures. MTBF can only be estimated by dynamic testing, which involves executing the program under various conditions and collecting data on its failures4. Therefore, very low MTBF is an issue that cannot be identified by static analysis tools. The other options, such as potentially endless loops, referencing a variable with an undefined value, and security vulnerabilities, are issues that can be identified by static analysis tools. Static analysis tools can detect potentially endless loops by analyzing the control flow and data flow of the program and checking for conditions that may never become false5. Static analysis tools can detect referencing a variable with an undefined value by checking the scope and initialization of variables and reporting any use of uninitialized variables6. Static analysis tools can detect security vulnerabilities by checking for common patterns of insecure code, such as buffer overflows, SQL injections, cross-site scripting, and weak encryption.

질문 # 61
What is test oracle?

A. The source of input conditions
B. The source of lest objectives
C. The source of expected results
D. The source for the actual results

정답：C

설명：
A test oracle is a mechanism or principle that can be used to determine whether the observed behavior or output of a system under test is correct or not1. A test oracle can be based on various sources of expected results, such as specifications, user expectations, previous versions, comparable systems, etc2. References:

질문 # 62
In which one of the following test techniques are test cases derived from the analysis of the software architecture?

A. Experience-based test techniques.
B. Black-box test techniques.
C. White-box test techniques.
D. Checklist-based test techniques.

정답：C

설명：
White-box test techniques are test design techniques where the test cases are derived from the internal structure of the software, including its architecture, code, and logical flow. These techniques involve the tester having knowledge of the internal workings of the software to create test cases that ensure all possible paths and conditions are tested. This is in contrast to black-box test techniques, which focus on input-output behavior without considering the internal structure. Reference: ISTQB CTFL Syllabus V4.0, Section 4.3

질문 # 63
Which sequence of stated in the answer choices is correct in accordance with the following figure depicting the life-cycle of a defect?

A. S0->S1 ->S2->S3->S5->S3->S4
B. S0->S1->S2->S3->S5->S1
C. S0->S1->S2->S3->S5->S1->S2->S3
D. S0->S1->S2~>S3->S4

정답：A

설명：
According to the ISTQB Certified Tester Foundation Level (CTFL) v4.0, the life cycle of a defect typically follows a sequence from its discovery to its closure. In the provided figure, it starts with S0 (New), moves to S1 (Assigned), then to S2 (Resolved), followed by S3 (Verified). If the defect is not fixed, it can be Re- opened (S5) and goes back for verification (S3). Once verified, it is Closed (S4).
