   A team is developing a safety-critical embedded system in C. The codebase is 200K lines, and the team has just completed a major refactoring of the memory management module. The project manager wants to catch defects early, before integration testing begins, and is concerned about null pointer dereferences and buffer overflows. The team has limited time and cannot afford a full manual review of every file. Which approach best addresses the manager's concern at this stage?

   • AConduct a full formal code review of the entire codebase, involving all senior developers, before any further work.
   • BRun an automated static analysis tool configured with MISRA C rules and warnings for null pointer and buffer issues.
   • CExecute the refactored module with a test harness that injects invalid pointers and oversized data to observe runtime behavior.
   • DDefer analysis until after integration testing, when the system is running, to see which defects actually manifest.

   A team is developing a new feature and has just completed the code. The team is about to start the testing phase. The project manager is concerned about the cost of fixing defects and wants to catch them as early as possible. The team has a CI pipeline that runs unit tests on every commit. The team also has access to static analysis tools. How should the team integrate static analysis into their process to best achieve the manager's goal?

   • ARun static analysis only during system testing, after all features are integrated.
   • BRun static analysis only during a formal code review at the end of the sprint.
   • CRun static analysis only when a defect is found by the unit tests.
   • DAdd static analysis to the CI pipeline, running it on every commit alongside the unit tests.

   A test manager is planning the test activities for a new release. The team has a history of introducing defects during code changes, and the manager wants to catch these as early as possible in the development lifecycle. The team uses a continuous integration (CI) pipeline. Where should static analysis be integrated to best achieve this goal?

   • AOnly during system testing, after all modules are integrated.
   • BIn the CI pipeline, running on every code commit before the build is deployed.
   • COnly during a formal code review at the end of each sprint.
   • DIn the production environment, monitoring for defects in real-time.

   How do dynamic analysis activities typically fit into the test process?

   • AThey are used to replace all manual testing activities
   • BThey are used only during unit testing
   • CThey are used alongside test execution to observe runtime behavior and identify defects
   • DThey are used only during the requirements phase

   A test analyst is investigating a rare, intermittent crash in a web application that occurs only under high user load. The crash log points to a specific code path, but the defect cannot be reproduced in a test environment with normal traffic. The analyst needs to gather more evidence about the failure. Which technique is most appropriate to apply first?

   • AAdd more logging to the code path and deploy to production to capture the next occurrence.
   • BUse a memory analysis tool while running a load test that simulates the high-traffic condition.
   • CReview the crash log and code path in a formal walkthrough with the development team.
   • DPerform a static analysis of the code path to identify all possible logic errors that could lead to a crash.
