ISQI CTAL-TA_V4.0 Exam Syllabus Topics:

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

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

Question 2

In your role as a Test Analyst for the development of a business application, you asked the Product Owner to help you understand how the various product risks would affect the users.
Which product risk management activity was this?

A. Risk mitigation
B. Risk identification
C. Risk assessment
D. Risk control

Question 3

How is a Test Analyst involved in an Incremental SDLC model?

A. In all increments, the Test Analyst organises the test activities in the same way
B. In each increment, the Test Analyst performs the test activities cyclically
C. In each increment, the Test Analyst always performs the same test activities
D. In all increments, the Test Analyst performs the test activities in a dynamic and adaptive way

Question 4

You have been appointed to be 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 on the various approaches to the junction. The project is still in the early stages of test planning, but it is already clear that despite a tight schedule its safety-critical nature demands careful and thorough testing.
You have been asked to decide whether automated test design would deliver benefits. Which characteristic of automated test design is MOST important for the development of this system?

A. Testware can be generated in various output formats, e.g. for use by different tools
B. Testware generated by tools usually contains fewer mistakes than testware created manually
C. Less maintenance effort for the testware after the system has gone live
D. Creating the model will expose defects in the test basis early in the project

Question 5

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

A. b), c) and g)
B. a), e) and f)
C. c), e) and f)
D. a), b) and d)
