Which of the following is a common technical issue that causes automation projects to fail to meet the planned return on investment?
Correct : B
A common technical issue causing automation projects to fail in delivering the planned return on investment is the lack of maintainability in their design. Automation frameworks and scripts that are not designed with maintainability in mind can become cumbersome to update and scale as the software evolves. This results in increased costs and effort over time to keep the automation relevant and effective, which can erode the expected returns on investment from the automation initiative .

You are working for a company that has a product in the field that has reached its capacity. The system cannot handle any more users without a significant degradation in performance and a significant spike in resource requirements. As a result, your new product has strict requirements for performance efficiency and a specific growth requirement that is estimated for the next three years.
What type of testing should you conduct to make sure the future requirements will be met?
Correct : C
For a product that has reached its capacity limits and requires testing to ensure it can handle projected growth, scalability testing is the most appropriate. Scalability testing evaluates a system's ability to manage an increasing workload without compromising performance or other operational capabilities. This type of testing will help confirm whether the system can handle the estimated increase in load, which is aligned with the strict performance efficiency and growth requirements for the next three years

You are a senior Technical Test Analyst on a new government project for the Air Force. The software you are testing is used to control the hydraulics for the landing gear for a supersonic, stealth aircraft. You are responsible for organizing the white-box testing that will be performed for this project.
Which of the following would be the most appropriate technique to apply in this situation?
Correct : B
In a high-risk environment such as controlling aircraft hydraulics, Modified Condition/Decision Coverage (MC/DC) is crucial. This technique ensures that all conditions within a decision have been tested independently, which is vital for understanding the impact of each condition on the decision's outcome. MC/DC is often required in safety-critical systems like aerospace software to achieve a high level of confidence in the software's reliability and safety .

Which of the following is true regarding maintainability?
Correct : B
Maintainability refers to how easily software can be maintained over time to correct faults, improve performance, or adapt to a changed environment. This quality factor becomes increasingly important the longer the system remains in the production environment because as systems age, they often require updates and modifications to continue meeting user needs effectively. This factor is critical for ensuring the system can be efficiently updated without causing downtime or significant expense.

You have conducted static analysis on several new modules for an existing product. You are now executing test cases and are seeing inconsistent problems including crashes. Intermittent error messages are appearing. Despite all your best efforts, you are not able to find reproducible scenarios to force these errors.
What problem in the code are you likely seeing?
Correct : A
Experiencing inconsistent problems such as crashes and intermittent error messages that do not have reproducible scenarios likely points to an issue with wild pointers. Wild pointers are pointers that do not point to a valid object of the appropriate type, often due to being uninitialized, pointing to deallocated memory, or having been overwritten accidentally.
