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

Question 1

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

Question 2

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?

A. (20,50), (20,51), (15,60), (25,60)
B. (20,40), (20,50), (20,60), (15,60), (25,60)
C. (20,50), (20,49), (15,60), (25,60)
D. (20,50), (20,49), (19,60), (21,60)

Question 3

Your project is developing an application to generate quotes for motor insurance. The calculation requires a wide range of input data and a reliable model of it has been built in a spreadsheet. There will not be enough time to get adequate functional correctness coverage from the base choice or pairwise techniques, so you have decided to do some random testing based on a probability distribution of variable values that is weighted towards their business criticality.
Which limitation of random testing should you be MOST concerned about?

A. Dependency on an automated test oracle to establish test results
B. Missing defects that are rooted in the meaning of data semantics
C. Generating tests that will exercise the same conditions repeatedly
D. The tests will focus on validation rather than verification

Question 4

You are your employer's most experienced TA. The organisation performs root cause analysis (RCA) thoroughly, but infrequently and only on individual defects that went live at the highest of the five Severity levels.
After six months of live operation for one system, particular concern has been expressed about the volume of usability and security defects and there is a strong desire to reduce their quantities. You have recommended adding product quality characteristics, per ISO 25010, to the defect report template.
How might this recommendation support RCA?

A. In combination with Severity, Quality Characteristic will isolate groups of defects that are causing most concern, so that RCA can be performed at group level
B. In combination with knowledge about how the defect was fixed, it will speed up RCA
C. It will enable Pareto analysis to be performed across the quality characteristics, in order to focus on those which have most defects
D. Classification by Quality Characteristic will enable more detailed analysis of the defect detection percentage (DDP)

Question 5

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?

A. Required Goods Entry / PR Creation Check
B. Enter Details of Required Goods / Is PR Created?
C. Enter Required Goods / Check PR Created
D. Required Goods / Check PR
