NEW QUESTION # 46
A simple drinks machine is described in the following state transition diagram:
How many test cases will be needed for Chow's 1-switch coverage?
Answer: A
Explanation:
The correct answer is C , because Chow's 1-switch coverage requires every valid sequence of two consecutive transitions to be covered. CTAL-TA v4.0 states that N-switch coverage applies to valid sequences of N+1 consecutive transitions , and specifically defines a 1-switch as a pair of incoming and outgoing transitions at a state.
Count the possible incoming-transition/outgoing-transition pairs at each state:
* S1 has 2 incoming transitions: clear, take drink, and 2 outgoing transitions: coffee, tea.
So, 2 × 2 = 4 1-switches.
* S2 has 4 incoming transitions: coffee, tea, dispensed from sugar, dispensed from milk, and 4 outgoing transitions: clear, sugar, milk, vend.
So, 4 × 4 = 16 1-switches.
* S3 has 1 incoming transition and 1 outgoing transition: 1 × 1 = 1 .
* S4 has 1 incoming transition and 1 outgoing transition: 1 × 1 = 1 .
* S5 has 1 incoming transition and 1 outgoing transition: 1 × 1 = 1 .
Total = 4 + 16 + 1 + 1 + 1 = 23 .
Therefore, the minimum quantity needed for full Chow's 1-switch coverage is 23 . Reference: CTAL-TA v4.

NEW QUESTION # 47
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: A
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 # 48
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.
System testing has finished and the test manager has asked you, the senior TA, to identify any parts of the product that should be focused on during acceptance testing. The results of this may be used to adjust the acceptance test plan.
You are using defect cluster analysis, only counting defects with severity levels 1 to 3, ignoring low severity levels 4 and 5. Function point analysis was used for estimating, so you have used function points as the unit of size for the various functional areas of the product. No numeric estimates of expected defect quantities were made for them individually but, as a result of product risk analysis, these functional areas have been ranked according to the amount of product risk that was predicted in them, with risk ranking 1 being the highest and
5 the lowest; the thoroughness of the testing performed so far has been proportional to that. The results are presented in the table below.

Which functional areas would you recommend for more test focus in acceptance testing?
a) Purchase Request entry
b) Purchase Request workflow
c) Purchase Request authorization
d) Supplier Identification
e) Purchase Order creation
Answer: C
Explanation:
The correct answer is C because defect cluster analysis must not be based on raw defect counts alone. CTAL- TA v4.0 states that after testing, the Test Analyst can identify actual defect-prone areas and compare predicted versus actual defect clusters; where discrepancies appear, more rigorous testing may be needed in those areas.
Here, size must be normalized using function points. The defect densities are: Purchase Request entry 30
/2000 = 15 defects per 1000 FP , Purchase Request workflow 15/1500 = 10 defects per 1000 FP , Purchase Request authorization 25/1000 = 25 defects per 1000 FP , Supplier identification 30/2000 = 15 defects per
1000 FP , and Purchase Order creation 30/1000 = 30 defects per 1000 FP .
The strongest actual clusters are therefore Purchase Order creation and Purchase Request authorization .
This is even more significant because authorization had the lowest predicted product risk ranking, 5 , so it should not have produced such a high defect density if the original risk assessment and test focus were accurate. Purchase Order creation also shows the highest defect density despite only medium predicted risk, ranking 3. Supplier identification and Purchase Request entry both have 30 defects, but they are larger areas and have only 15 defects per 1000 function points; Supplier identification was also the highest predicted risk area, so more defects there are less surprising. Reference: CTAL-TA v4.0, Software Defect Prevention , test result analysis and predicted-versus-actual defect cluster analysis.
NEW QUESTION # 49
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: B
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 .

NEW QUESTION # 50
You are a TA in the development of a road traffic control application, which will be installed at busy road junctions, to control the operation of traffic signal lights according to sensors that detect traffic volume. This safety-critical project is still in the early stages of test planning and the project schedule is tight.
The Test Manager has asked you if crowd testing should be included in the project's test strategy. You do NOT think it should. Which limitation of crowd testing MOST influences your view?
Answer: B
Explanation:
The correct answer is A . Crowd testing can provide scale, diversity of devices, and real-world variety, but its major weakness for a safety-critical road traffic control system is the variability of tester skill and therefore the variability of test quality. CTAL-TA v4.0 discusses crowd testing as a technique that may be useful in some contexts but has limitations, including variability in tester capability, control, coordination, documentation, and confidentiality. For a safety-critical system, the decisive factor is not geographical inconvenience or volume of findings; it is the need for controlled, rigorous, repeatable, competent testing against safety-relevant behavior.
Traffic signal control software must be tested using disciplined techniques, traceable test conditions, formal models, carefully selected scenarios, and controlled environments. Incorrect behavior could cause accidents, traffic conflict, or unsafe signal timing. Crowd testers are unlikely to have the necessary domain knowledge, safety-testing discipline, access to representative simulation rigs, or ability to produce the evidence expected for a safety-critical project.
Option B is a real crowd-testing limitation, but coordination overhead is not the strongest objection here.
Option C may matter, but the question gives no special confidentiality driver. Option D is relevant, but documentation burden is secondary to the unacceptable variability in testing quality. Reference: CTAL-TA v4.
