ISTQB-CTAL-TA Exam Dumps - ISTQB Advance Level Questions and Answers

Comprehensive and Detailed in Depth Explanation:

Session-Based Test Management (SBTM) for exploratory testing follows these steps:

Test Charter Creation:To outline the goals and scope of the session.

Time-Boxed Test Execution:Allows focused, exploratory testing within a fixed duration.

Debriefing Session:To discuss findings, assess coverage, and review results.

Option D accurately reflects this structure, making it the correct answer.

The comment that should be made about the Supercar specification is that boundaries for stock levels are ambiguous. The specification states that the site will allow an order to be processed if at least one of the chosen vehicle configurations is in stock, but it does not define what constitutes “in stock” or how many units are available for each configuration. This makes the specification unclear and inconsistent, as it does not provide enough information for testing or implementation.

Eight 0-switch test cases are needed to achieve 100% 0-switch coverage. A state transition test technique is a technique that tests the behavior of a system or component based on its states and transitions between them. A 0-switch test case is a test case that covers one state and its associated actions and events. To achieve 100% 0-switch coverage, all states and their associated actions and events must be covered by at least one test case. The states for this scenario are:

Enter PIN

PIN OK

PIN not OK

1st try

2nd try

3rd try

Access to act

Eat card

Examining the test basis is an appropriate task for the Test Analyst during the test analysis phase, as it involves identifying and evaluating the sources of information for test analysis, such as requirements, design documents, user stories, etc. Reviewing test estimates, creating a test execution schedule, and evaluating status against exit criteria are tasks that belong to other phases of testing, such as test planning, test implementation, and test closure.

The risk impact for requirement R1 should be categorized as high or very high, as it is a business critical requirement that affects the core functionality of the system. The risk impact is determined by assessing the potential negative consequences of a failure or defect in the system. The other statements are not true, as they are based on assumptions or irrelevant factors. Verified References: [ISTQB® Certified Tester Advanced Level Test Analyst CTAL-TA], Section 1.2.1, page 13.

Comprehensive and Detailed in Depth Explanation:

Project C:Since therequirements are vague and inconsistent, creatinghigh-level test casesis more suitable. High-level test cases are flexible and allow for interpretation, which is crucial when requirements are not clearly defined.

Project D:Since the project aims forregression testing,low-level test casesare more appropriate. They are detailed and specific, essential for consistency during repeated manual or automated regression testing.

Therefore, the correct answer isD (Project C - High level test cases. Project D - Low level test cases).

Comprehensive and Detailed In-Depth Explanation:

R01:Low likelihood, not the highest priority.

R02:Relates to Iteration 3, which is out of scope for Iterations 1 and 2.

R03:High impact and medium likelihood, relevant to both IOS (Iteration 1) and Android (Iteration 2).

R04:Medium impact and medium likelihood, less critical compared to R03.

Therefore, the correct answer isA (R03).

Comprehensive and Detailed in Depth Explanation:

Interoperability testingverifies that different systems can work together and correctly exchange data.

a) Truncated patient name:An interoperability defect as it indicates incorrect data handling between systems.

b) Difficult navigation:Ausability defect, not related to system interoperability.

c) Incorrect phone number format recognition:An interoperability defect because it affects data exchange.

d) Slow data retrieval:Aperformance defect, not related to system interaction.

e) Spelling errors in field names:Ausability or user interface defect, not interoperability.

Therefore, the correct answer isD (b, d).

Nine test cases are required to test all pairs using the pairwise testing technique based on the classification tree. Pairwise testing is a technique that tests all possible pairs of inputs for a given scenario using a mathematical algorithm to reduce the number of combinations. The inputs for this scenario are:

Power Unit: Petrol, Electric, Hybrid

Body Style: Saloon, Hatchback, SUV

Color: Red, Blue

The number of test cases is equal to the number of combinations generated by the algorithm that cover all pairs of inputs. Verified References: [ISTQB® Certified Tester Advanced Level Test Analyst CTAL-TA], Section 3.5.2, page 42.

 Four test conditions to be identified from requirements REQ2 and REQ3 are not covered by the three test cases. A test condition is an item or event of a component or systemthat could be verified by one or more test cases, such as a function, transaction, feature, quality attribute, or structural element. The test conditions to be identified from REQ2 and REQ3 are:

Number of hours exposed to the sun = A

Number of hours exposed to the sun = B

Number of hours exposed to the sun = C

Intensity of sun radiation = low

Intensity of sun radiation = medium

Intensity of sun radiation = high

Intensity of sun radiation = extreme

The test conditions that are not covered by the three test cases are:

Number of hours exposed to the sun = A

Intensity of sun radiation = low

Intensity of sun radiation = high

Intensity of sun radiation = extreme
