   A test analyst is evaluating a static analysis tool for a project that uses a mix of C and C++. The team wants to detect wild pointers early in the development cycle. Which type of static analysis finding is most indicative of a potential wild pointer?

   • AA pointer variable is used before it is assigned a value on some execution path
   • BA pointer is compared to `NULL` in an `if` statement
   • CA pointer is passed to a function that expects a `const` pointer
   • DA pointer is cast to an integer type

   A test analyst is documenting the impact of a wild pointer defect found in a payment processing system. The defect can cause the system to write transaction data to an incorrect memory location. What is the most critical potential impact of this defect?

   • AA compile-time error that prevents the application from building
   • BA memory leak that slowly consumes system memory
   • CCorruption of unrelated data structures, leading to incorrect transaction records
   • DA minor performance degradation due to extra memory access

   What is a key characteristic of dynamic analysis for detecting wild pointers?

   • AIt does not require any changes to the program
   • BIt analyzes the source code without running it
