Defect taxonomies are categorized lists of defects that can be used to identify and prevent common types of errors in software development and testing. They can also be used to design test cases that target specific defect types, such as security vulnerabilities. Therefore, using a list of known defect types to penetrate the security of computer systems is an example of the use of defect taxonomies. References = Defect Taxonomies - The Practical Guide to Defect Prevention (Chapter 10), Using Defect Taxonomies for Testing Requirements, Defect Based Approach using Defect Taxonomy, Requirements-based testing with defect taxonomies

Installability testing is a type of non-functional testing that focuses on verifying that the software can be installed, upgraded, and uninstalled without errors or interruptions1. It is usually performed by a technical test analyst who has knowledge of the installation requirements, dependencies, and configurations2. The main objectives of installability testing are to ensure that the software is compatible with different platforms, environments, and hardware specifications, and that the installation and de-installation processes are functional, reliable, and secure3. Usability issues, such as the clarity, simplicity, and efficiency of the installation and de-installation user interfaces, are not the primary concern of installability testing, and may be better addressed by other types of testing, such as usability testing or user acceptance testing4. References = Installation testing - Wikipedia; ISTQB Advanced Level Technical Test Analyst Syllabus 2019, section 4.3.2; Mastering Installability Testing: A Key Software Quality Assurance Process; Installation Testing | Complete Overview Of Installation Testing

Exhibit B is the only state transition diagram that matches the text description of Acme’s elevator door rules. It shows that the doors can transition between four states: Opened, Closing, Closed, and Opening. The transitions are triggered by either commands (open or close) or sensors (opened or closed). The diagram also shows that the open command can reverse the closing state, and the close command can reverse the opening state, as specified in the text. The other exhibits do not show the correct transitions or conditions for the elevator door system. References =
