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

1. You are testing a program which calculates the best airspeed for optimal fuel economy of a new type of aero engine. The result depends on atmospheric pressure at the airplane's current height, the air temperature at the airplane's current height, and on the airplane's current fuel load. The best airspeed:
* decreases by 4 knots (nautical miles per hour) for every 5mb (millibar) decrease in atmospheric pressure,
* increases by 6 knots for every 1°C decrease in air temperature,
* increases by 1 knot for every 1,000kg decrease in fuel load.
You have a test case which predicts that at an atmospheric pressure of 1,000 mb, an air temperature of 10°C and a fuel load of 400,000kg, the optimal airspeed for an Airbus A380 is 600 knots.
Which test case would verify the metamorphic relation described in the three bullet points above?

A) Pressure 1050mb, temp. 9°C, fuel 350,000kg, optimal airspeed = 590 knots
B) Pressure 950mb, temp. 9°C, fuel 350,000kg, optimal airspeed = 616 knots
C) Pressure 950mb, temp. 11°C, fuel 400,000kg, optimal airspeed = 610 knots
D) Pressure 950mb, temp. 10°C, fuel 360,000kg, optimal airspeed = 620 knots

2. 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.

A) c) and d)
B) b) and e)
C) b) and c)
D) a) and e)

3. You have been assigned as Test Analyst on a project that is in the test design stage. Test cases have been written, which activity should you do next before test design complete?

A) Identify the test cases that are suitable for automation
B) Decide which test cases should be high-level and which ones should be low-level
C) Have the test cases reviewed by the stakeholders
D) Identify constraints and dependencies that will affect the sequence of test execution

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

5. The test basis for your latest project contains the activity diagram that is shown below. The business architect has confirmed that this model has been reviewed and approved by the stakeholders.

Which of the following conclusions is correct?

A) The diagram may contain a defect but this cannot be confirmed until the results of the tests created from it are known
B) The diagram may contain a defect but this cannot be confirmed until test cases have been designed from it
C) The diagram is correct because it has been reviewed and approved by the stakeholders
D) The diagram contains at least one defect because it contains an internal inconsistency
