ISQI CTAL-TA_V4.0 Valid Test : ISTQB Certified Tester Advanced Level Test Analyst (CTAL-TA v4.0)

You are assigned to an Agile team as a Test Analyst. In most ways, the team seems to be working well.
Iteration planning goes smoothly because the user stories are good quality. Most defects that are found by testing are fixed in the same iteration and those that do go live are not causing significant dissatisfaction amongst stakeholders. However, the team is unhappy because the Defect Removal Efficiency rate, measured for each iteration, is less than 80%.
What would be the MOST effective contribution by you as a TA, to improve the situation?

• A. Participating in root cause analysis
• B. Reviewing requirements
• C. Participating in retrospectives
• D. Defect data collection and evaluation

During a sprint retrospective it was noted that some test cases were interpreted differently between the Product Owner and the Test Analysts. Which test case quality criteria may need some attention?

• A. Completeness
• B. Understandability
• C. Precision
• D. Consistency

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?

• A. Acceptance testing
• B. Test analysis, including requirements review
• C. System testing
• D. Test design, including solution design review

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

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?

• A. If b increases by x% then h increases by ((x * 2) / 3)%
• B. If b increases by x then h increases by ((x * 2) / 3)%
• C. If b increases by x then area increases by ((x * 2) / 3)%
• D. If b increases by x% then area increases by ((x * 2) / 3)%
