According to the CHFI v11 objectives underWeb Application ForensicsandLog Analysis, knowing the default storage locations of web server logs is essential for reconstructing web-based attacks. On Windows Server operating systems,Internet Information Services (IIS)stores its HTTP and HTTPS request logs by default in the directory:

%SystemDrive%\inetpub\logs\LogFiles

This directory contains subfolders such as W3SVC1, W3SVC2, etc., where each folder corresponds to a specific IIS website instance. The log files stored here record critical forensic details includingclient IP addresses, timestamps, HTTP methods, requested URLs, status codes, user agents, and referrers. These artifacts allow investigators to identify attack vectors such as SQL injection, command injection, directory traversal, brute-force attempts, and web shell uploads.

The other options are incorrect because they do not represent default IIS log locations. %AppData% is user-profile specific, %ProgramFiles% contains application binaries rather than logs, and %SystemRoot%\Logs\IIS is not a standard IIS logging path.

The CHFI Exam Blueprint v4 explicitly coversIIS web server architecture and log analysis, emphasizing familiarity with default log paths to ensure timely evidence acquisition and accurate incident reconstruction. Therefore, %SystemDrive%\inetpub\logs\LogFiles is the correct and exam-aligned answer
