Question 31

Which of the following does NOT contribute to a more effective review preparation by the Technical Test Analyst?

Ensure that participants spend enough time during preparation, e.g.. by managing checking rate (number of pages checked per hour during review preparation).
Ensure that participants spend enough time during preparation, e.g.. by managing checking rate (number of pages checked per hour during review preparation).
Managing logging rate (number of defects logged per minute during the meeting).
Managing logging rate (number of defects logged per minute during the meeting).
The usage of review checklists.
The usage of review checklists.
Review training for the Technical Test Analyst.
Review training for the Technical Test Analyst.
Suggested answer: B
Explanation:

An effective review preparation by a Technical Test Analyst includes ensuring that participants are well-prepared and that they spend enough time on preparation, which can be managed by checking the rate (option A). The use of review checklists (option C) and providing review training (option D) are also methods that contribute to more effective review preparation. However, managing the logging rate (option B), or the number of defects logged per minute during the meeting, is not related to the preparation phase but rather to the defect detection and logging phase during the actual review meeting. It is not a preparation activity but a review execution activity.

Question 32

A product risk assessment has revealed the following product risks:

* lack of usability requirements

* security during on-line transactions

* perceived performance of the system and response time from the user interface

* a required availability of almost 100%

To address the 4th risk, which of the following quality characteristics for technical testing should be part of the test approach?

Adaptability
Adaptability
Reliability
Reliability
Portability
Portability
Compatibility
Compatibility
Suggested answer: B
Explanation:

To address the product risk of requiring an availability of almost 100%, the quality characteristic of reliability should be part of the test approach. Reliability testing focuses on the ability of the system to perform under expected conditions for a specified period of time. It is essential for systems that need to be operational continuously or near-continuously. This characteristic encompasses the system's uptime, fault tolerance, recoverability, and the ability to perform under anticipated conditions, all of which are relevant to maintaining high availability.

Question 33

You have been assigned to perform a review on code provided below:

ISTQB CTAL-TTA image Question 33 48510 09182024210654000000

Which type of defect should you report as part of the code review?

Endless loop
Endless loop
Unreachable code
Unreachable code
Too many nested levels
Too many nested levels
No defects should be reported, code is correct.
No defects should be reported, code is correct.
Suggested answer: A
Explanation:

The code provided contains a potential endless loop. The loop is conditioned on the variable 'E' being less than 1 (IF E < 1), but within the loop, there is no operation that modifies the value of 'E'. Therefore, once the loop is entered, if the condition A > B holds true, the value of 'E' remains unchanged, leading to an endless loop situation. The decrement of 'A' in line 15 does not guarantee an exit condition for the loop, as it does not affect the value of 'E'. This is a control flow defect that could cause the program to hang or crash.

Question 34

Report Export Collapse

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?

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

In the context of consumer electronics, where there is rapid growth in embedded software and pressure to minimize code size due to cost constraints, dynamic analysis can be particularly useful for improving system performance. Dynamic analysis involves examining the system's behavior during execution, which can provide insights into the efficiency of the code at runtime, memory utilization, and processing speed. In a high-end TV project where the use of ROM and RAM is under severe restrictions, dynamic analysis would be most appropriately applied to improve system performance, ensuring that the software runs efficiently within the available hardware resources. This supports the project context by contributing to the optimization of the software to run within the constraints of the microcontroller used, thereby potentially reducing costs.
