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

According to theCHFI v11 Operating System Forensicsobjectives, the Windows Registry is a critical source of evidence for reconstructinguser activity, particularly in insider threat investigations. One of the most important Registry artifacts for identifyingrecently accessed foldersis theBagMRU key.

TheBagMRUkey is part of the Windows ShellBags artifact structure and is specifically designed to trackfolder navigation history. It stores hierarchical information about folders accessed by a user, includingfolder names, directory paths, and access order relationships. These keys allow forensic investigators to determine which directories a user browsed, even if the folders were accessed via Windows Explorer and later deleted from the system.

While theMRUListExvalue exists within ShellBag-related keys, it only defines theorder of accessand does not store the actual folder path or name. TheBagskey, on the other hand, storesfolder view settingssuch as icon size, window position, and display preferences—not access history. TheNodeSlotvalue is associated with Jump Lists and application usage tracking rather than directory navigation.

CHFI v11 explicitly highlightsShellBags and BagMRU keysas essential artifacts for reconstructing user behavior, especially in cases involving data exfiltration or insider misuse. Therefore, the correct and CHFI-verified answer isBagMRU key (Option A).

According to theCHFI v11 Computer Forensics Fundamentals and Data Acquisitionobjectives,volatile datarefers to information that is stored temporarily in system memory and is lost when the system is powered off or restarted. One of the most valuable and commonly overlooked forms of volatile data is theclipboard contents.

The clipboard temporarily storestext, images, URLs, file paths, credentials, commands, and other datathat a user copies or cuts during normal system interaction. In corporate espionage and insider threat investigations, clipboard data can revealrecent user intent, such as copied confidential documents, links to exfiltration sites, snippets of sensitive emails, or commands prepared for execution. CHFI v11 highlights clipboard analysis as an important part oflive forensic investigations, especially when investigators need to understandrecent user activitythat may not yet be written to disk.

The other options represent different forensic artifacts but do not match the scenario. Network shared resources, driver/service configurations, and print spool files are not designed to store recently copied text or images. They are either non-volatile or unrelated to direct user copy-paste actions.

Therefore, the volatile data being examined in this case is theclipboard contents, makingOption Dthe correct and CHFI v11–verified answer.

According to theCHFI v11 Web Application Forensics and Network & Web Attacks module, attackers commonly useencoding and obfuscation techniquesto bypass input validation mechanisms, web application firewalls (WAFs), and intrusion detection systems. One such advanced technique isdouble URL encoding, which involves encoding already URL-encoded characters a second time.

In URL encoding, the forward slash / is represented as %2F. When this value is encoded again, % becomes %25, resulting in %252F. InOption A, multiple occurrences of %252f clearly indicate that characters such as / and comment markers (/* */) have beendouble encoded. When processed by the web server or application, the input may be decoded twice, ultimately reconstructing a valid SQL injection payload like UNION SELECT, thereby bypassing security filters.

Options B and C rely oncase manipulation and keyword splitting, which are evasion techniques butnot double encoding. Option D useshex-encoded control characters, which is a different obfuscation method and does not represent double URL encoding.

CHFI v11 explicitly highlightsdouble encodingas a common technique used in SQL injection attacks to evade detection and filtering mechanisms. Therefore, the URL that clearly demonstratesdouble-encoded SQL injection payloadsisOption A, making it the correct and CHFI-aligned answer.
