Answer : B

Comprehensive and Detailed Explanation From Exact Extract:

The 'dd' command is a Unix/Linux utility used to perform low-level copying of data, including forensic imaging. It allows bit-for-bit copying of drives or memory, making it a common tool in Linux-based forensic environments.

Windows does not natively support 'dd'; similar imaging tools are used there.

The command syntax and file paths indicate Linux/Unix usage.

Digital forensics training and NIST SP 800-101 mention 'dd' as a reliable imaging tool in Linux forensic workflows.

Answer : D

Netstat is a standard Windows command line utility that displays active network connections, routing tables, and network interface statistics. It is widely used in forensic investigations to identify current and past TCP/IP connections, including IP addresses and port numbers associated with remote hosts. This information helps investigators identify if the suspect computer has active connections to other machines potentially used for data collection or command and control.

Telnet is a protocol used to connect to remote machines but does not display current network connections.

Openfiles shows files opened remotely but not network connection details.

Xdetect is not a standard Windows tool and not recognized in forensic investigations.

According to NIST SP 800-86 and SANS Digital Forensics guidelines, netstat is an essential tool for gathering network-related evidence during system investigations.

Answer : B

Comprehensive and Detailed Explanation From Exact Extract:

The chain of custody is a documented, chronological record detailing the seizure, custody, control, transfer, analysis, and disposition of evidence. Maintaining this record proves that the evidence was protected and unaltered, which is essential for court admissibility.

Each transfer or access must be logged with date, time, and handler.

Breaks in the chain can compromise the legal validity of evidence.

According to NIST and forensic best practices, the chain of custody documentation is mandatory for reliable evidence handling.

Answer : C

Comprehensive and Detailed Explanation From Exact Extract:

An email header contains metadata about the email including sender, receiver, routing information, and content details. The Content-Type header specifies the media type of the email body (e.g., text/plain, text/html, multipart/mixed), indicating how the email content should be interpreted.

Sender's MAC address is not typically included in email headers.

Number of pages is not relevant to email metadata.

Message-Digest is a term related to cryptographic hashes but is not a standard email header field.

RFC 5322 and forensic email analysis references outline that email headers contain fields like Content-Type describing the format of the message content, essential for proper parsing and forensic examination.

Answer : B

Comprehensive and Detailed Explanation From Exact Extract:

Steganography is the technique of hiding information within another file, message, image, or medium to conceal the existence of the information itself. It differs from encryption in that the data is hidden, not just scrambled.

Steganalysis is the detection or analysis of hidden data.

Encryption and cryptography involve scrambling data but do not inherently hide its existence.

NIST and digital forensics guidelines define steganography as the art of concealed writing or data hiding, used by criminals to evade detection.
