NEW QUESTION # 21
You are working on a project to replace an old sales and merchandising system with a new system that will be based on modern platforms. The old system Is still in production but is poorly documented and expensive to maintain. The new version will be developed using modern technology. The main requirements for the system are that it shall:
* Load sales data, sent electronically from the stores each evening, into a central database.
* Produce actual sales reports for the merchandisers, whose job is to manage stock levels in stores.
* Produce sales forecast reports based on a combination of sales history and forecasting parameters. The parameters will be entered by the merchandisers into a browser-based front end and the reports will be produced overnight. The users will be able to see the reports next day, on screen or in print, by requesting this through the browser.
Requirements 1 and 2 are satisfied by the existing system and will be rewritten with no significant changes.
Requirement 3 is new. The development will use your company's Agile SDLC, with 2-week iterations.
Technical skill levels in the team are high and the approach to automate test execution is aggressive. Each requirement will be specified with user stories, will be released only when complete, and will need more than one iteration. The main business benefit will come from requirement 3, which depends on the other two requirements, and the stakeholders are keen to get this into production as soon as possible.
Release planning has begun for requirement 3 and you need to know at a high level what the testing scope will be, to ensure that the correct resources will be available. Which functional test techniques will be MOST effective for this release?
a) Domain testing
b) Combinatorial testing
c) Random testing
d) CRUD testing
e) Scenario-based testing
f) Decision table testing
g) Exploratory testing
Answer: B
Explanation:
The correct answer is C : domain testing, scenario-based testing, and decision table testing . Requirement
3 is new and business-critical. It involves entering complex forecasting parameters, generating reports overnight from sales history and parameters, and then viewing or printing those reports through the browser.
Domain testing is appropriate because forecasting parameters and sales-history values form input domains with partitions and boundaries. CTAL-TA v4.0 states that domain testing extends equivalence partitioning and boundary value analysis to domains with multiple parameters and complex partitions.
Scenario-based testing is also essential because the requirement describes an end-to-end user/business flow:
enter parameters, run overnight report generation, request report output, view or print result. CTAL-TA states that scenario-based testing evaluates behavior in realistic workflows and is often used in system and acceptance testing from the user's perspective.
Decision table testing fits because forecast calculation behavior is likely governed by business rules involving sales history, parameters, thresholds, and report-generation rules. CTAL-TA classifies decision table testing as a rule-based technique for stateless business rules. Random testing is inferior because the requirement is clearly specified, not poorly understood. CRUD testing is not the strongest match because Requirement 3 is not mainly an entity lifecycle problem.
NEW QUESTION # 22
You are defining key words to test an application which will create a Purchase Request (PR) from details of goods that a Merchandiser wants their organization to buy. When valid details have been entered, the resulting PR will be sent to the Merchandise Manager for authorization.
You have a diagram in Business Process Modeling Notation and this section shows the initial steps in this process:
For the first process, when "Something is needed" , which option contains the MOST appropriate keywords for action and verification?
Answer: D
Explanation:
The correct answer is B . In CTAL-TA v4.0 keyword-driven testing, the Test Analyst identifies and specifies keywords by analyzing the test basis. Keywords are classified into action keywords and verification keywords . Action keywords interact with the test object, such as executing a function, submitting data, or navigating through the application. Verification keywords represent assertions that check whether the actual result matches the expected result. The syllabus also states that keywords should contain a verb plus noun , use the imperative form , and be unique in meaning.
Option B , Enter Required Goods / Check PR Created , is strongest because both keywords use imperative verb-based wording. Enter Required Goods is an action keyword because it describes the business action performed by the Merchandiser. Check PR Created is a verification keyword because it checks the expected result: a Purchase Request has been created.
Option A is weak because Required Goods is only a noun phrase, not an action keyword. Option C has a reasonable action, but Is PR Created? is phrased as a question rather than an imperative verification keyword. Option D uses noun-style labels rather than clear executable keywords. Reference: CTAL-TA v4.0, Section 1.3.6 Developing Test Scripts Using Keyword-Driven Testing .
NEW QUESTION # 23
The following minimized decision table shows the rules for rewarding members of a hotel's loyalty scheme who have booked a room, according to the type of room (luxury or not) and/or whether they have prepaid for breakfast (yes or no). The loyalty scheme has tiers Bronze, Silver and Gold. All combinations are feasible.
Using the checksum procedure, what do you notice about the structure of the minimized table?
Answer: B
Explanation:
The correct answer is B . In CTAL-TA v4.0 decision table testing, the checksum procedure is used to detect structural problems in a minimized decision table. A rule without any "-" condition represents one full-table combination. Each "-" multiplies that rule's checksum by the number of possible values for that condition. If the minimized-table checksum is higher than the original-table checksum, some rules overlap or additional rules exist; if it is lower, the table is incomplete; if equal, the minimization may be structurally correct.
The original full table has 3 loyalty tiers × 2 luxury-room values × 2 breakfast values = 12 feasible combinations . The minimized rules score as follows: Rule 1 G/Y/- = 2 , Rule 2 G/N/- = 2 , Rule 3 S/Y/- = 2
, Rule 4 S/-/- = 4 , Rule 5 B/-/Y = 2 , Rule 6 B/-/N = 2 . Total checksum = 2 + 2 + 2 + 4 + 2 + 2 = 14 . Since
14 > 12 , the minimized table cannot be structurally clean. The overlap is visible: Rule 3 covers Silver + Luxury + either breakfast value , while Rule 4 covers Silver + any room type + any breakfast value , so the Silver/Luxury combinations are covered twice. Option C is wrong because all condition values are represented. Option D alone is weaker than B , because the actual symptom here is overlap. Reference: CTAL- TA v4.0, Section 3.3.1 Decision Table Testing .
NEW QUESTION # 24
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: D
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 # 25
A pricing system for determining the postage cost of a company's letters examines two input variables, representing the length L of the envelope in centimeters and the weight W of the letter in grams. Envelopes can only have three lengths: 15 cm Small, 20 cm Standard, and 25 cm Large.
For standard length envelopes, 20 cm, a premium postage rate is applied if the weight is equal to or greater than 50 grams. This is represented as:
IF L = 20 AND W > = 50 THEN RETURN Cost "Premium rate"
Which set of test points, each represented as variables L, W , achieves 100% simplified domain coverage for the Standard letter postage cost domain?
Answer: D
Explanation:
The correct answer is B . Simplified domain coverage requires boundary-focused ON and OFF points. CTAL- TA v4.0 states that for borders defined by < , #, > , or #, simplified domain coverage requires one ON and one OFF point. For an equality border, it requires one ON point and two OFF points on different sides of the border, with OFF points as close as possible according to the given precision.
The premium Standard-letter domain is defined by L = 20 and W > = 50 . For the W > = 50 border, (20,50) is the ON point because 50 is included, and (20,49) is the closest OFF point. For the L = 20 equality border, (20,50) also serves as the ON point, while (15,60) and (25,60) are OFF points on the two available sides of the Standard envelope length, because envelope lengths are restricted to 15, 20, and 25 cm.
Option A includes unnecessary extra points and does not represent the minimal required simplified coverage set. Option C uses 19 and 21, which are invalid envelope lengths. Option D misses the closest OFF point for the inclusive weight boundary because it uses 51 instead of 49. Reference: CTAL-TA v4.0, Section 3.1.1 Domain Testing , simplified domain coverage.
