In the STLC, a Risk Management Plan provides a structured approach to identify, assess, and prioritize risks associated with the testing process. It offers a framework for making decisions and allocating resources based on potential impacts and likelihood of risks.

White-box testing is focused on the internal structures of an application. While Cyclomatic Complexity, Statement Coverage, and Path Testing are white-box techniques, Usability Testing is a type of black-box testing, focusing on user experience.

Enforcing a strong password policy would be the primary recommendation, as it directly addresses the core issue of weak passwords. This policy would mandate criteria like password length, complexity, and change frequency. While MFA and regular audits are beneficial, addressing the root cause is essential.

During Test Planning, the Test Plan is the key document that captures all aspects of testing, including the identification and assignment of roles and responsibilities, resources, schedules, and other relevant details to guide the testing efforts throughout the cycle.

Usability Testing focuses on a user's experience with the application. It ensures that the product is easy to use and provides a good user experience. Issues like button placements, text alignment, and other design-related aspects that might hamper the user's experience or make the application difficult to navigate are typically identified in Usability Testing.

Load testing focuses on understanding the behavior of the system under a specific load or request volume. Metrics like latency (response time) and throughput (number of requests processed per unit time) are crucial.

Error Guessing is a testing technique where testers rely on their past experiences and knowledge of system failures to identify potential defects. Instead of using a systematic approach, testers use their intuition to "guess" where defects might be present and construct tests based on these hunches, drawing from previous issues they have encountered.

While Load Time, Response Time, and Throughput are common metrics used in performance testing to measure various aspects of the system's performance, "Number of Defects" is not a performance metric. It is typically associated with functional testing and bug tracking.

Continuous Delivery focuses on ensuring that code changes can be deployed to production at any time, making the release process reliable. Continuous Deployment, on the other hand, ensures these changes are automatically deployed to production frequently without human intervention.

QTP (now known as UFT - Unified Functional Testing) stands out because it supports Visual Basic Scripting (VBScript) for customization of the test procedures. This offers testers flexibility and power in designing test scripts tailored to specific testing needs, setting it apart from some other tools.

Test cases with high repeatability are ideal for automation because they need to be executed multiple times across different test cycles. Automating such tests can save significant time and effort in the long run, thereby yielding a higher Return on Investment (ROI). Repetitive tasks are where automation shines the most.

A Design Review is a static analysis technique that focuses on the design aspects of the software. Conducting thorough design reviews ensures that the design is consistent, meets requirements, and can identify potential issues early on. This can significantly reduce the number of defects introduced during the design phase.
