EC-COUNCIL EC-Council Digital Forensics Essentials (DFE) Sample Questions (Q58-Q63):

NEW QUESTION # 58
Which of the following file systems of Windows replaces the first letter of a deleted file name with the hex byte code "e5h"?

Answer: C

Explanation:
InFAT (File Allocation Table)file systems (FAT12/16/32), directory entries are fixed-size records that include an8.3 filename field. When a file is deleted, FAT typically does not immediately erase the file's content; instead, it marks the directory entry as deleted by replacing thefirst character of the filenamewith the special marker byte0xE5(often written asE5h). This is a key forensic behavior because it means the file's metadata entry may still be present in the directory table, and the data clusters may remain recoverable until they are reused and overwritten. Examiners can often reconstruct the original filename's first character only through context or by correlating other artifacts, but the remainder of the directory entry (timestamps, size, starting cluster) can still assist recovery.
The other options do not match this mechanism.NTFSuses Master File Table records and marks deletions differently (file record flags and index changes), not by overwriting the first filename byte with E5h.EFSis an encryption feature layered on NTFS, not a distinct file system deletion marker.FHSis a UNIX/Linux directory layout standard, unrelated to Windows disk structures. Therefore, the correct answer isFAT (A).


NEW QUESTION # 59
Which of the following acts was passed by the U.S. Congress in 2002 to protect investors from the possibility of fraudulent accounting activities by corporations?

Answer: D

Explanation:
TheSarbanes-Oxley Act (SOX)was enacted by the U.S. Congress in2002in response to major corporate accounting scandals and was specifically designed toprotect investorsby improving the accuracy, reliability, and integrity of corporate disclosures and financial reporting. SOX strengthens governance and accountability by requiring executive management (notably the CEO and CFO) to certify the correctness of financial statements and by mandating stronger internal controls over financial reporting. From a digital forensics and compliance perspective, SOX is closely tied to the need for reliableaudit trails, properrecords retention, and demonstrable control over systems that store or process financial data. Investigators frequently rely on SOX- driven logging, access controls, and change management records to determine who accessed financial systems, what changes were made, and whether those actions align with authorized procedures.
The other options do not match the question's purpose or jurisdiction: theElectronic Communications Privacy Actaddresses interception and access to electronic communications,GDPRis an EU data protection regulation (not a 2002 U.S. act focused on investor protection), and "Information Privacy Act 2014" is not the 2002 U.S.
corporate anti-fraud legislation. Therefore, the correct answer isSarbanes-Oxley Act (SOX) (C).


NEW QUESTION # 60
Steve, a professional hacker, attempted to hack Alice's banking account. To accomplish his goal, Steve used an automated tool to guess Alice's login credentials. The tool uses a trial-and-error method by attempting all possible combinations of usernames and passwords to determine the valid credentials.
Identify the type of attack initiated by Steve in the above scenario.

Answer: B

Explanation:
The scenario describes an automated, trial-and-error attempt that triesall possible combinations of usernames and passwordsuntil a correct credential pair is found. This is the defining characteristic of abrute-force attack.
In digital forensics terminology, brute force is a direct password-guessing method that relies on exhaustive attempts (or systematically generated candidates) rather than tricking the user or exploiting a software flaw.
Investigators commonly recognize brute-force activity through artifacts such as repeated authentication failures in security logs, high-frequency login attempts from a single IP or distributed sources, account lockout events, and abnormal spikes in authentication traffic. In banking and web environments, it may also appear as repeated POST requests to login endpoints with varying credential pairs and consistent user-agent patterns, sometimes accompanied by throttling or CAPTCHA triggers.
The other options do not match the described "attempting all possible combinations" behavior.
Phishingobtains credentials by deception (fake emails/sites). ATrojan horsesteals data by running malicious code on the victim's system.Data manipulationfocuses on altering data integrity rather than credential guessing. Therefore, the correct attack type isBrute-force attack (A).


NEW QUESTION # 61
Which of the following layers of the TCP/IP model includes protocols such as Frame Relay, SMDS, Fast Ethernet, SLIP, PPP, FDDI, ATM, Ethernet, and ARP to enable a machine to deliver the desired data to other hosts in the same network?

Answer: B

Explanation:
The protocols listed-Frame Relay, SMDS, Fast Ethernet, SLIP, PPP, FDDI, ATM, Ethernet, and ARP- belong to the portion of the TCP/IP model responsible forlocal network deliveryand direct interaction with the physical media and link-layer addressing. In TCP/IP terminology, this is theNetwork Access layer(also called the Link layer or Network Interface layer). It combines functions that map closely to the OSIData LinkandPhysicallayers.
This layer is essential for delivering frames within the same network segment because it governs how devices access the medium (e.g., Ethernet), how frames are formatted and transmitted, and how hardware addressing works.ARP (Address Resolution Protocol)is especially important here: it resolvesIP addresses to MAC addressesso that an IP packet can be encapsulated into a link-layer frame and delivered to the correct local host or next-hop gateway. Technologies like PPP/SLIP support point-to-point links, while Frame Relay/ATM represent WAN/link technologies, all of which still sit under IP and provide the mechanisms for moving data across the immediate network path.
TheInternet layerhandles IP routing between networks, theTransport layerprovides end-to-end host communications (TCP/UDP), and theApplication layerprovides user protocols. Therefore, the correct layer isNetwork access layer (A).


NEW QUESTION # 62
Sam is working as a loan agent for a financial institution. He frequently receives a number of emails from clients providing their personal details for loan approval. As these emails contain sensitive data, Sam had set up a feature that directly downloads the emails on his device without storing a copy on the mail server. Which of the following protocols provides the above-discussed email features?

Answer: B

Explanation:
The scenario describes an email-retrieval configuration in which messages aredownloaded to a client device andnot retained on the server. This behavior aligns withPOP3 (Post Office Protocol v3), a legacy but widely referenced mail access protocol that retrieves email from a server mailbox to a local client. In standard POP3 operation, the client authenticates to the mail server, issues retrieval commands (e.g., to list and download messages), and may then issue a delete command so that downloaded messages are removed from the server mailbox. Digital forensics references commonly contrast POP3 with IMAP:IMAP is designed for server-side mailbox synchronization and typically leaves mail stored on the server, whereas POP3 is oriented towardclient-side storageand supports workflows where server copies are not preserved after download. The other options are unrelated to email retrieval:SHA-1is a cryptographic hash function used for integrity checks,ICMPsupports network diagnostics and control messaging, andSNMPis used for network device management and monitoring. From an investigative standpoint, POP3 usage can reduce server-resident evidence and shift evidentiary value tolocal artifacts(mail client databases, cache, OS traces, backups), which is consistent with the intent described in the question.
