To answer this question, you need to understand the definitions and characteristics of a walkthrough and an inspection. Let's go through each option to understand why it is correct or incorrect:

Option A) An inspection is led by the author, whilst a walkthrough is led by a trained moderator. This option is incorrect. In a walkthrough, the author typically guides the session, while in an inspection, a trained moderator or inspector leads the process.

Option B) An inspection has a trained leader, whilst a walkthrough has no leader. This option is incorrect. Both a walkthrough and an inspection typically have a leader or facilitator who guides the process.

Option C) Authors are not present during inspections, whilst they are during walkthroughs. This option is incorrect. Authors may or may not be present during both walkthroughs and inspections. The presence of authors can vary depending on the specific context or purpose of the walkthrough or inspection.

Option D) A walkthrough is led by the author, whilst an inspection is led by a trained moderator. This option is correct. The main difference between a walkthrough and an inspection is that in a walkthrough, the author typically leads the session, while in an inspection, a trained moderator or inspector leads the process.

Therefore, the correct answer is Option D. A walkthrough is led by the author, whilst an inspection is led by a trained moderator.

To answer this question, you need to understand the purpose and importance of a Test Strategy.

Option A) As there are many different ways to test software, thought must be given to decide what will be the most effective way to test the project on hand. - This option is correct because a Test Strategy helps in determining the most effective and efficient way to test the software based on the project requirements and constraints. It considers factors such as the project scope, objectives, risks, resources, and timelines to determine the appropriate testing approach.

Option B) Starting testing without prior planning leads to a chaotic and inefficient test project - This option is correct because a Test Strategy provides a structured approach to testing by defining the scope, objectives, and test techniques to be used. It helps in avoiding ad-hoc testing and ensures that testing efforts are well-planned and organized.

Option C) A strategy is needed to inform the project management how the test team will schedule the test cycles - This option is correct because a Test Strategy includes the scheduling and sequencing of test activities, including test cycles. It helps in communicating the testing timelines and milestones to the project management and stakeholders.

Option D) Software failure may cause loss of money, time, business reputation, and in extreme cases injury and death. It is therefore critical to have a proper test strategy in place. - This option is correct because a Test Strategy is critical for ensuring the quality and reliability of the software being developed. It helps in identifying potential risks and mitigating them through effective testing. Software failures can have severe consequences, such as financial loss, damage to reputation, and even safety hazards. A proper test strategy helps in minimizing these risks and ensuring that the software meets the desired quality standards.

The correct answer is D. This option is correct because it emphasizes the critical importance of having a proper test strategy in place to prevent potential software failures and their associated consequences.

To answer this question, we need to understand the concept of when to stop testing. Let's go through each option to understand why it is correct or incorrect:

Option A) All the planned tests have been run - This option is incorrect because stopping testing just because all the planned tests have been run does not guarantee that all potential risks and faults have been identified. There may still be undiscovered issues that need to be addressed.

Option B) Time has run out - This option is incorrect because stopping testing just because time has run out does not ensure that all necessary testing has been conducted. It is possible that important tests were not executed due to time constraints.

Option C) All faults have been fixed correctly - This option is incorrect because fixing all identified faults does not necessarily mean that all potential risks and issues have been addressed. There may still be undiscovered faults or risks that need to be evaluated.

Option D) Both 1 and 3 - This option is incorrect because as discussed above, stopping testing just because all planned tests have been run or all faults have been fixed correctly does not guarantee that all risks and issues have been considered.

Option E) It depends on the risks for the system being tested - This option is correct because the decision to stop testing should be based on the risks associated with the system being tested. Testing should continue until an acceptable level of risk has been achieved or until the stakeholders, such as the project manager or product owner, determine that the level of risk is acceptable.

The correct answer is E) It depends on the risks for the system being tested. This option is correct because stopping testing should be based on the level of risk associated with the system.
