312-49v11 Exam Dumps - Computer Hacking Forensic Investigator (CHFIv11)

The correct answer is C because the signature FF D8 FF E0 is a well-known JPEG file header, and FF D9 is the standard JPEG end-of-image marker. In forensic file analysis, CHFI v11 expects candidates to understand file signatures and identify common file formats from hexadecimal headers and trailers, especially when working with carved fragments from unallocated space. The second signature in the question, 42 4D, identifies a BMP file because those bytes correspond to the Bitmap header. This contrast helps confirm that the first fragment is the JPEG one. Recognizing these signatures is important when file extensions are missing, corrupted, or intentionally changed to mislead investigators. JPEG files are especially common in photo evidence, email attachments, web artifacts, and recovered user content, so being able to identify them from raw hex data is a practical forensic skill. In CHFI-style questions, when the fragment begins with FF D8 FF E0 and closes with FF D9, the correct file type is JPEG. That answer aligns directly with the blueprint objective on image file analysis and hexadecimal file identification.

The correct answer is C because when a live system is found displaying an active session, the first responder should immediately preserve what is visible on the screen before that information changes or disappears. CHFI v11 places strong emphasis on first response, documenting the electronic crime scene, and preserving volatile or transient evidence. A screen may show logged-in users, running applications, chats, remote sessions, command windows, or other live artifacts that can vanish if the user session locks, the system sleeps, or the machine is powered down. Photographing the monitor and noting what is displayed creates an early evidentiary snapshot that helps reconstruct the scene later. Option A is good general practice, but it is broader and less urgent than capturing the live display. Option B may matter if witnesses exist, and option D is a later evidence-handling concern. The question asks what should be prioritized at the scene to support later reconstruction, and CHFI-style reasoning favors recording the immediate visual state of active systems before that state changes. That makes photographing the monitor and noting observations the best first-response action.

Option C. Olevba is the best answer because CHFI v11 explicitly includes Analyzing Suspicious Word, Excel, and PDF Documents and Tools to Analyze Suspicious Word and PDF Documents as part of malware forensics and static/dynamic analysis.

The suspicious file here is a Word document , and the question asks for a tool suitable for static analysis to detect hidden malicious content. Olevba is specifically known for analyzing Office documents and extracting or inspecting VBA macro content , suspicious strings, and obfuscation indicators without executing the document. That fits the requirement exactly.

FLOSS is mainly used for extracting obfuscated strings from binaries. PEStudio is more appropriate for PE files such as Windows executables and DLLs. Cuckoo Sandbox is a dynamic analysis environment, not the most direct tool for static Office document inspection. Therefore, within CHFI’s malware-document analysis scope, the most effective choice is Olevba for static analysis of the suspicious Word file.

The correct answer is C because the scenario explicitly affects all three core security properties at once. Customer records were exposed, which means confidentiality was lost. Stored data was modified without authorization, which means integrity was compromised. Access to critical systems was disrupted, which means availability was affected. This three-part impact is the classic confidentiality, integrity, and availability model that underpins organizational information security analysis. CHFI v11 includes the impact of cybercrimes at the organizational level and expects candidates to identify not only business consequences, but also the underlying security principles directly harmed by an incident. The other choices describe real downstream effects, such as theft, reputational harm, and financial disruption, but they are consequences rather than the most direct information-security impact demonstrated by the facts in the question. In exam reasoning, when a single incident simultaneously exposes data, alters it, and interrupts access, the most accurate answer is the loss of confidentiality, integrity, and availability of information stored in organizational systems. That is the clearest conceptual match to the evidence described.

Option C is the correct answer because the workstation has already been powered down , so the priority is now to preserve the remaining non-volatile evidence and acquire it in a forensically sound manner. Powering the system back on could alter timestamps, logs, temporary files, registry artifacts, and other evidence. CHFI emphasizes choosing the correct acquisition method based on the state of the device and preserving integrity during evidence collection.

Since volatile data is already lost due to shutdown, the correct first step is not to boot the machine, but to begin forensic imaging for later offline analysis. This allows the investigator to create an exact duplicate of the storage media and conduct the examination on the copy rather than the original source.

Option A would unnecessarily modify the system state. B is irrelevant because a powered-down workstation has no ongoing traffic to monitor. D is weaker because creating a bootable copy is not the immediate forensic priority; the first requirement is a proper evidence image. Therefore, the best CHFI-aligned response is to leave the system off and initiate forensic imaging for offline analysis.
