NEW QUESTION # 20
You are working on a project to build a purchasing system. The main requirements for the system are that it shall:
* Allow users to enter details of items that they wish to have purchased and, from these details, create a purchase request.
* Take each purchase request through a workflow that will allow the requestor's line manager to approve the request, reject it or return it for clarification / modification.
* Forward approved requests to the Purchasing Department.
* Allow purchasers to find the best available supplier for each approved request and place the request on that supplier as a purchase order.
The solution is being developed according to the company's traditional V-model methodology. The requirements are clearly documented and include a business process model.
The main release has now been live for three months and you are working on the first maintenance release.
The test manager has asked you, the senior TA, to identify those parts of the test process which were most and least effective at finding defects in the main release.
You have collected statistics for the independent test activities, i.e. excluding developers' testing, including only the 178 defects in the three highest of your five defect severity levels. The results are presented in the table below:
Assume that all defects not found at the first opportunity could have been, e.g. that all defects that escaped into acceptance testing were within the scope and objectives of system testing. By applying Defect detection percentage (DDP) analysis, which test activity was LEAST effective?
Answer: A
Explanation:
The correct answer is B . CTAL-TA v4.0 explains that Defect Detection Percentage is used to evaluate how effectively a test level or activity detects defects, and a low DDP indicates a high percentage of escaped defects, meaning the activity was ineffective and should be analyzed for improvement. The official CTAL-TA sample-answer material gives the formula as DDP = D / (D + E) , where D is defects detected in that phase and E is defects that escaped that phase and were detected later.
For test analysis including requirements review , only requirements defects are in scope at the first opportunity. It found 13 requirements defects, while 52 requirements defects escaped and were found later: 12 in test design, 20 in system testing, 10 in acceptance testing, and 10 in live operation. Therefore, DDP = 13 / (13 + 52) = 13 / 65 = 20% .
For comparison, test design found 40 of the 100 defects it could have found, so DDP = 40% . System testing found 75 of 125 possible remaining defects, so DDP = 60% . Acceptance testing found 25 of 50 possible remaining defects, so DDP = 50% . The lowest DDP is therefore test analysis, including requirements review . Reference: CTAL-TA v4.0, Section 5.3.1 Analyzing Test Results to Improve Defect Detection .
NEW QUESTION # 21
Your company, which specializes in medical software, has designed an application for use on smartphones and tablets, that calculates a person's BMI (Body Mass Index). How can a test analyst BEST contribute to adaptability testing for this application?
Answer: C
Explanation:
The correct answer is C . Adaptability testing concerns whether a component or system can be adapted to different or evolving hardware, software, operational, or usage environments. The ISTQB Glossary defines adaptability as the degree to which a system can be adapted to various or evolving hardware, software, or other operational or usage environments. CTAL-TA v4.0 also places adaptability within the Test Analyst's user-facing non-functional testing scope, alongside usability, installability, and interoperability.
For a BMI application intended for smartphones and tablets, the best Test Analyst contribution is to design tests across the intended target devices, screen sizes, operating-system versions, browsers or WebViews if applicable, input methods, and device configurations. This directly checks whether the application remains usable and functional when adapted to its supported mobile and tablet environments.
Option A is coexistence testing , because it checks whether the BMI app adversely affects other health applications on the same device. Option B is closer to installability/update testing , because it checks launching and functioning after an updated version is downloaded. Option D is functional correctness testing
, because it checks whether the BMI calculation result is correct for given inputs. Reference: CTAL-TA v4.0, Testing Quality Characteristics , adaptability under user-facing non-functional quality characteristics.
NEW QUESTION # 22
A savings bank rewards its customers with a £100 bonus when they reach the age of 21, if they have held a savings account for more than 3 years and have at least £2,000 in the account at that time.
Assume that Age is measured in whole years, Account term in whole years, and Account balance to two decimal places, i.e., pounds and pence.
The intended rule is:
IF Age = 21 AND Account term > 3 years AND Account balance > = £2000.00 THEN Pay £100 bonus You have a suite of test cases with the following values:
* TC1 Age = 21, Account term = 3 years, Account balance = £2000.00
* TC2 Age = 20, Account term = 6 years, Account balance = £500.00
* TC3 Age = 20, Account term = 2 years, Account balance = £3000.00
Which of the following test cases should you add to the suite to achieve 100% Reliable domain coverage?
Answer: B
Explanation:
The correct answer is B . Reliable domain coverage requires stronger boundary evidence than simplified domain coverage. CTAL-TA v4.0 defines ON, OFF, IN, and OUT points and states that for borders defined by < , #, > , or #, reliable domain coverage requires one ON, one OFF, one IN, and one OUT point . For an equality operator, it requires one ON point and two OFF points located on different sides of the border .
The existing tests already cover several required items. For Age = 21 , TC1 gives the ON point and TC2/TC3 give the lower-side OFF point at age 20; the missing equality-side point is age 22. For Account term > 3 , TC1 gives OFF at 3, TC2 gives IN at 6, TC3 gives OUT at 2; the missing ON point is 4. For Account balance > = £2000.00 , TC1 gives ON at £2000.00, TC3 gives IN at £3000.00, and TC2 gives OUT at
£500.00; the missing closest OFF point is £1999.99. Option B supplies all three missing items in a single test case: age 22, term 4, and balance £1999.99. Reference: CTAL-TA v4.0, Section 3.1.1 Domain Testing , Reliable domain coverage.
NEW QUESTION # 23
Your project is developing an application to process claims against insurance policies. Which of the following is a good example of CRUD completeness testing?
Answer: B
Explanation:
The correct answer is C because CRUD completeness testing is a static activity. CTAL-TA v4.0 defines CRUD as create, read, update, and delete, and states that CRUD testing verifies the lifecycle of data entities processed by the test item. The syllabus distinguishes two parts: CRUD completeness testing , which statically verifies whether all possible CRUD operations occur for every entity, and CRUD consistency testing , which dynamically checks whether functions interact correctly when handling the entity.
For an insurance-claims application, the key entity is the claim . A technical review checking whether the architecture/specification includes the ability to create, read, update, and delete claim records directly matches CRUD completeness. It is concerned with whether the full claim lifecycle has been included, not whether the lifecycle behaves correctly during execution. Option A is a strong example of CRUD consistency testing because it executes a lifecycle sequence and checks post-delete behavior. Option B is also dynamic execution, so it is not the best match for completeness. Option D is requirements elicitation completeness, not specifically CRUD completeness for the implemented claim entity. Reference: CTAL-TA v4.0, Section 3.2.1 CRUD Testing .
NEW QUESTION # 24
You are working on a project to build an application that will handle insurance claims. The main requirements for the system are that it shall:
* Allow users to enter details of claims that have been submitted by insured customers.
* Take each claim through a workflow that will allow an assessor to approve the request, reject it or request clarification from the claimant.
* Send approved requests to the accounts payable system for payment.
The solution is being developed according to the company's standard V-model methodology. The requirements are clearly documented and include a business process model. Operational profiles have been created to guide performance testing.
A risk-based approach to testing is used; frequency of use and role of the user are major factors in feature risk assessment.
System testing has almost finished but a major change to the approval workflow is just about to be delivered.
A standard regression test pack has not yet been established, but ad-hoc regression testing has already been performed on earlier builds.
As a TA. you have updated the list of product risks and must now decide the scope of the regression testing.
Which pair of techniques will be MOST effective for selecting the regression tests?
a) History-based, driven by the results of the regression tests run so far b) Risk-based, driven by the updated list of product risks and its traceability to the tests c) Operational profile-based, driven by the likely patterns of use of the relevant transactions d) Requirement traceability matrix-based, driven by the links from affected requirements to related tests e) Impact analysis, driven by consultation with technical stakeholders to identify what might be affected.
Answer: D
Explanation:
The correct answer is B : risk-based selection and impact analysis . The scenario says a risk-based approach is already used and that the Test Analyst has updated the list of product risks. CTAL-TA v4.0 states that risk- based regression test selection uses traceability from the regression suite to a risk register; when a change is made and the risk register is updated, the Test Analyst adjusts the regression suite to cover the highest risk levels. That directly matches technique b .
The second required technique is impact analysis because the change is a major modification to the approval workflow. The TA must understand which workflow states, transitions, claims data, interfaces, assessor actions, clarification paths, rejection paths, approval paths, and accounts payable handoff could be affected.
CTAL-TA states that impact analysis can be used for regression test selection when the TA knows which tests interact with changed configuration items, and that regression scope must be reviewed every cycle because it may be impossible to execute all regression tests.
Option a is weak because prior regression was ad hoc and no standard regression pack exists, so history is unreliable. Option c helps performance or usage-flow prioritization but is not as directly targeted as updated product risk plus impact analysis. Option d is useful, but technical impact analysis is stronger for a major workflow change.
