Which category of tool is used to observe and inspect the sequence of Win32 API calls within applications?

• A. API Monitor
• B. DriverView
• C. DNSChanger
• D. NetFlow Traffic Analyzer

Answer: (A)

Observing and inspecting the sequence of Win32 API calls within applications is done with API monitoring tools. These tools attach to a running process or instrument code to log each Windows API function invocation in real time, including the function name, the parameters passed, and the return values. This lets you see the exact order of operations an application performs with the OS, such as opening files, querying the registry, creating processes, or making network requests, which is invaluable for debugging or malware analysis. API Monitor is a representative tool in this category because it’s designed to capture and display these API calls as they happen, giving a clear view of the app’s behavior at the Windows API level. The other options focus on different domains: DriverView specializes in loaded device drivers, DNSChanger relates to DNS manipulation, and NetFlow Traffic Analyzer tracks network traffic flows rather than API usage.
