Test planning should be a continuous activity throughout the software development lifecycle. This ensures that the test plans remain relevant and effective, adapting to any changes in the project scope, requirements, or timelines.

The task "verify the test environment set up is correct" relates to the Implementation and Execution phase of the fundamental test process. This phase includes setting up the test environment, creating test data, and executing test cases.

To verify the non-functional requirements such as the support for a minimum number of enquiries per hour, availability, and response time during peak loads, the most appropriate set of test types would include Performance Testing to assess the responsiveness and stability, Load Testing to verify the system's ability to handle expected user loads, and Stress Testing to determine the system's behavior under extreme conditions. These tests collectively ensure that the system meets the specified non-functional criteria.

Test planning involves defining the overall approach to testing, including setting objectives, strategies, and resources. It ensures that the level of detail in test procedures is appropriate for the subsequent test execution phase. Effective test planning helps in aligning the testing activities with the project goals and ensures that the tests are executed as per the defined procedures.

Experience-based techniques rely on the testers' knowledge, skills, and experience, as well as insights from developers and users, to design test cases. These techniques do not depend on formal models or the internal structure of the software but rather on practical experience and understanding of how the software is likely to be used and where defects are likely to be found​​.

Independent testing is crucial because independent testers can provide an unbiased perspective and verify the assumptions made during the specification and implementation phases. This helps in identifying defects that might be overlooked by developers who are closely involved in the creation of the system.

It is generally not feasible to perform exhaustive testing due to time and resource constraints. Instead, testing efforts should be focused using risk analysis and priorities to ensure the most critical areas are tested thoroughly. This approach helps in maximizing the effectiveness of the testing process while managing resources efficiently.

When evaluating risks, both the likelihood of failure and the potential cost of impact must be considered. The risk with the highest level is determined by the product of these two factors. In this case, a 10% likelihood of failure with a potential cost of impact of $500,000 results in a higher risk (expected impact) compared to the other options. The expected impact is calculated as likelihood multiplied by impact, which is higher for option B​​.
