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: 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 # 21
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: B
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 # 22
You are testing a program which should calculate the area of a trapezium and have decided to use metamorphic testing. The formula Area = (((a + b) / 2) * h) where a and b are the lengths of the two parallel sides, and h is the height when the parallel sides are horizontal.
Which ONE of the following would be an appropriate metamorphic relation?
Answer: C
Explanation:
The correct answer is B , but the question is slightly under-specified as written. CTAL-TA v4.0 defines a metamorphic relation as a property that describes how a change in test input is reflected in the expected result.
It is used to create follow-up test cases from a source test case and then evaluate the source and follow-up results jointly.
For the trapezium formula, if b changes while a and h remain unchanged, the area must change, not the height. Therefore, options C and D are structurally wrong because changing an input side length does not imply a change in h . Option A is also weak because it mixes an absolute increase in b with a fixed percentage increase in area, without considering the original values of a , b , and h . Option B is the only option that correctly expresses the expected-result relationship: a percentage increase in b causes a predictable percentage increase in area . Strictly, the exact percentage depends on the contribution of b to a + b ; the shown 2/3 relation is valid when b / (a + b) = 2/3 . Reference: CTAL-TA v4.0, Section 3.3.2 Metamorphic 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: A
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.

NEW QUESTION # 24
A system will be developed to support the administration of table-tennis tournaments. The following requirements for the enrolment of entrants have been provided:
R1. High. The administrator shall be able to enter the entrant's name, address, phone number/s (mobile and/or home), email and social media handles. Validation rules for these data items are provided separately.
R2. High. The administrator shall be able to enter the entrant's current world ranking (up to 250) and their relationship with the tournament sponsors (i.e. clothing / equipment / endorsement).
R3. High. The administrator shall be able to enter the entrant's attendance history at previous events (i.e.
finalist / played / withdrew during event / withdrew before event).
R4. Medium. From the entrant's address the system shall derive whether or not the entrant lives locally and, on the basis of that combined with other rules that are provided separately, shall suggest how much of the tournament's overall prize fund should be offered to the entrant as their individual attendance fee.
R5. Low. The administrator should be able to change the suggested attendance fee and the system should then deduct this from the remaining prize fund balance accordingly.
You have been asked to review the requirements using perspective-based reading, from your viewpoint as the TA who will be writing functional correctness system test cases. Assume that the other rules referred to by requirements R1 and R4 have been reviewed and are satisfactorily testable. Which conclusion would you reach?
Answer: C
Explanation:
The correct answer is A . Using perspective-based reading, the TA must review the requirements from the viewpoint of someone who must derive functional correctness test cases. CTAL-TA v4.0 states that perspective-based reading requires reviewers to attempt to use the test basis to generate the work product they would derive from it; for a tester, that means attempting to create tests and checking whether all necessary information is present.
R1 is testable because the data-entry items are listed and the validation rules are explicitly provided separately and assumed testable. R4 is also testable because the derivation and attendance-fee rules are separately provided and assumed testable. R5 is testable as a functional rule: change the suggested attendance fee, then verify that the remaining prize fund balance is reduced accordingly.
The weak requirements are R2 and R3 . R2 does not fully define the valid model for "relationship with the tournament sponsors": it is unclear whether clothing, equipment, and endorsement are mutually exclusive, whether multiple relationships may apply, or whether "no relationship" is valid. R3 is also incomplete because "attendance history at previous events" is not fully defined: it is unclear whether this is one value, multiple event records, or a history per event, and some values overlap conceptually, such as finalist and played. These gaps prevent complete functional correctness test design. Reference: CTAL-TA v4.0, Sections
