EC-COUNCIL EC-Council Digital Forensics Essentials (DFE) Sample Questions (Q40-Q45):

NEW QUESTION # 40
Alice and John are close college friends. Alice frequently sends emails to John attaching her pics with friends.
One day, Alice sent an email to John describing all the details related to the final year project without specifying the actual purpose. John missed the message as he frequently receives emails from her and did not arrive for a project seminar.
Which of the following email fields could Alice have used in the above scenario to highlight the importance of the email?

Answer: C

Explanation:
TheSubjectfield is the primary email header element used to communicate thepurpose and urgencyof a message at a glance. Digital forensics training emphasizes that email messages consist ofheaders(routing and descriptive metadata) and abody(content). Among user-visible header fields, the Subject line is specifically intended to summarize what the email is about, helping recipients prioritize and correctly interpret the message without opening it. In the scenario, John routinely receives casual emails from Alice (often with pictures). When Alice sent a project-related email "without specifying the actual purpose," John treated it like routine mail and overlooked its significance. A clear, descriptive subject such as "Final Year Project Seminar
- Attendance Required" would have flagged the message as time-sensitive and different from her usual emails, reducing the chance it would be missed.
The other options do not serve this purpose.Dateis automatically assigned and mainly supports ordering and timeline reconstruction rather than highlighting importance.CcandBcccontrol who receives copies and can affect visibility or secrecy, but they do not summarize intent for the recipient. Therefore, the field best suited to highlight importance isSubject (A).


NEW QUESTION # 41
Which of the following layers of the TCP/IP model serves as the backbone for data flow between two devices in a network and enables peer entities on the source and destination devices to communicate with each other?

Answer: D

Explanation:
In the TCP/IP model, theTransport layeris responsible forend-to-end communication between peer entitieson the source and destination systems. "Peer entities" here refers to the corresponding transport components (and the applications that use them) on two different hosts communicating across a network. This layer forms the practical "backbone" of host-to-host data flow because it provides the mechanisms that allow data to be deliveredfrom one endpoint process to another endpoint processreliably or efficiently, depending on the protocol used.
The Transport layer includes protocols such asTCPandUDP. TCP supports connection-oriented communication with sequencing, acknowledgments, retransmissions, and flow control-features that are fundamental when reconstructing sessions during network forensic investigations (e.g., rebuilding a file transfer or a web session). UDP provides connectionless delivery used by many services where speed is preferred over guaranteed delivery, which is also significant in investigations of DNS, streaming, or certain malware communications.
By contrast, theInternet layerfocuses on logical addressing and routing (IP), theNetwork access layerhandles local delivery on the physical/link network, and theApplication layerprovides user-facing protocols.
Therefore, the layer enabling peer communication between endpoints is theTransport layer (C).


NEW QUESTION # 42
James, a forensic specialist, was appointed to investigate an incident in an organization. As part of the investigation, James is attempting to identify whether any external storage devices are connected to the internal systems. For this purpose, he employed a utility to capture the list of all devices connected to the local machine and removed suspicious devices.
Identify the tool employed by James in the above scenario.

Answer: A

Explanation:
The requirement is tolist devices connected to a local Windows machine, specifically to identifyexternal storage devicesthat may be attached and potentially used for data theft or malware introduction. In Windows forensic practice, investigators often start by enumerating currently mounted volumes and recently connected removable media so they can correlate device presence with suspicious activity timelines and user actions.
DriveLetterViewis a utility designed to display the complete mapping ofdrive letters to storage devices
/volumes, includingremovable drives(USB flash drives, external HDDs), optical media, network-mapped drives, and local partitions. It helps quickly identify what storage devices are present and accessible on the system at the time of inspection, which fits the scenario where James captures a list of connected devices and removes suspicious ones.
The other tools do not match this purpose.ESEDatabaseViewis used to inspect Extensible Storage Engine databases, not enumerate attached storage.ProcDumpis used for creating process memory dumps for debugging/forensic analysis of processes, not for listing connected drives.PromiscDetectrelates to detecting network interfaces in promiscuous mode (packet sniffing), not external storage enumeration. Therefore, the correct tool for identifying connected storage devices isDriveLetterView (C).


NEW QUESTION # 43
Which of the following standards and criteria version of SWGDE mandates that any action with the potential to alter, damage, or destroy any aspect of original evidence must be performed by qualified persons in a forensically sound manner?

Answer: B

Explanation:
The statement in the question matchesSWGDE Principle 1, Standards and Criteria 1.7, which explicitly requires thatany action that could alter, damage, or destroy original digital evidence must be performed by qualified personnel in a forensically sound manner. In digital forensics doctrine, this requirement exists because digital evidence is highly fragile: routine interactions (booting a system, opening a file, connecting storage, running commands) can change timestamps, overwrite unallocated space, modify logs, or trigger encryption/key rotation. SWGDE's emphasis on "qualified persons" and "forensically sound manner" aligns with core evidentiary expectations: minimizing changes to original media, using controlled and repeatable methods (e.g., write-blocking, validated imaging, documented procedures), and ensuring actions are defensible under scrutiny.
Options 1.1, 1.3, and 1.5 relate to broader quality and procedural requirements (quality systems, SOP review, appropriate tools), but they do not contain the specific mandate about potentially altering original evidence.
The exact phrasing about alteration/damage/destruction and qualified handling is associated withStandards and Criteria 1.7, makingBthe correct choice.


NEW QUESTION # 44
Which of the following techniques is used to compute the hash value for a given binary code to uniquely identify malware or periodically verify changes made to the binary code during analysis?

Answer: D

Explanation:
File fingerprintingis the forensic technique of generating acryptographic hash(such as MD5, SHA-1, SHA-
256) for a file to create aunique, repeatable identifierfor that exact byte sequence. In malware forensics, analysts compute hashes to (1)uniquely identifya suspicious binary across cases and tools, (2) confirm whether two samples are identical or different variants, and (3)verify integrity over time-for example, ensuring the sample did not change during copying, extraction, sandbox handling, or during an analysis workflow that might inadvertently modify the file (e.g., patching, unpacking outputs, or tool-side normalization). Re-hashing at different stages provides a defensible way to demonstrate that the analyzed artifact is the same as the acquired artifact, supporting evidentiary integrity and chain-of-custody principles commonly emphasized in digital forensics documentation.
The other techniques do not primarily serve this purpose.Strings searchextracts readable text fragments but does not produce a unique integrity identifier.Local and online malware scanninguses signatures/reputation and may identify families, but it is not an integrity verification mechanism for the exact file bytes.Malware disassemblyhelps understand logic and instructions, not compute an identity hash. Therefore, the correct answer isFile fingerprinting (A).
