ISQI ISTQB Certified Tester Advanced Level - Technical Test Analyst (V4.0) Sample Questions:

1. Consider the pseudo code provided below:

Given the following tests, what additional test(s) (if any) would be needed in order to achieve 100% statement coverage, with the minimum number of tests?
Test 1: A = 7, B = 7, Expected output: 7
Test 2: A = 7, B = 5, Expected output: 5

A) A=7, B=9, Expected output: 7
B) A=6, B=12, Expected output: Bingo! and A=7, B=9, Expected output: 7
C) A=6, B=12, Expected output: Bingo!
D) No additional test cases are needed to achieve 100% statement coverage.

2. Below is the pseudo-code for the Win program:

The bingo program contains a data flow anomaly. Which data flow anomaly can be found in this program?

A) It is recommended to use a variable instead of the hard-coded print results "Win" and *Loose".
B) Variable 'D" is defined but subsequently not used.
C) Variable 'A" is not assigned a value before using it.
D) The program does not contain any comments.

3. A major Caribbean bank typically develops their own banking software using an Agile methodology.

A) In stall ability
B) Adaptability
C) Replaceability
D) Co-existence

4. Within the world of consumer electronics, the amount of embedded software is growing rapidly. The amount of software in high-end television sets has increased by a factor of about eight over the last six years. In addition, the market of consumer electronics has been faced with a 5 -10% price erosion per year. The price of a product is, among a number of other things, determined by the microcontroller used. Therefore, the use of ROM and RAM remains under high pressure in consumer electronic products, leading to severe restrictions on code size.
Within a new high-end TV project, it has been decided to apply dynamic analysis.
Which of the quality goals listed below is MOST appropriate to the project context?

A) Improve system performance by providing information on run-time system behaviour.
B) Prevent failures from occurring by detecting wild pointers and loss of system memory.
C) Evaluate network behaviour.
D) Analyse system failures which cannot easily be reproduced.

5. A medical company has performed a safety criticality analysis using the IEC61508 standard. The software components to be developed have been categorized by Safety Integrity Level (SIL). Most components have been rated at SIL 1 or 2, and a few components at SIL 4.
After some discussions with the QA manager, the project has decided to adhere to the recommendations for test coverage provided by the IEC61508 standard.
Which level and type of test coverage should at least be used for the components rated at Safety Integrity Level (SIL) 2?

A) 100% statement coverage, 100% decision coverage and 100% multiple condition coverage
B) 100% statement coverage
C) 100% statement coverage and 100% decision coverage
D) 100% statement coverage, 100% decision coverage and 100% MC/DC coverage
