EC-COUNCIL EC-Council Digital Forensics Essentials (DFE) Sample Questions (Q16-Q21):

NEW QUESTION # 16
Which of the following network protocols creates secure tunneling through which content obfuscation can be achieved?

A. SSH
B. UDP
C. SNMP
D. ARP

Answer: A

Explanation:
SSH (Secure Shell)is specifically designed to provide anencrypted channelover an untrusted network. In digital forensics and incident response, SSH is well known for supportingtunneling/port forwarding, where traffic for another protocol (for example, HTTP, database connections, or remote desktop) is encapsulated inside an SSH session. Because the SSH session encrypts payload data (and can also protect authentication and command content), the tunneled traffic becomesobfuscated to network monitoring toolsthat can only see metadata such as source/destination IPs, port numbers (often TCP/22), timing, and byte counts. This capability is frequently discussed in forensic references as a mechanism that can hinder content inspection and complicate attribution of user actions purely from packet payload analysis.
By contrast,SNMPis primarily for network management and monitoring, not secure tunneling.ARPresolves IP- to-MAC addresses on local networks and does not provide encryption or tunneling.UDPis a transport protocol that can carry data for many applications but provides no built-in security or tunneling features by itself.
Therefore, the protocol that creates secure tunneling enabling content obfuscation isSSH (C).
event logs) to establish user intent and sequence of actions. Therefore, the correct option isBrowsingHistoryView (B).

NEW QUESTION # 17
Jack, a forensic investigator, was appointed by an organization to perform a security audit on a Linux system.
In this process, Jack collected information about the present status of the system and listed all the applications running on various ports to detect malicious programs.
Which of the following commands can help Jack determine any programs/processes associated with open ports?

A. netstat -rn
B. netstat -i
C. netstat -tulpn
D. ip r

Answer: C

Explanation:
On Linux, a key step in a forensic triage or security audit is mappingopen/listening portsto theowning processso investigators can identify suspicious services (backdoors, unauthorized daemons, rogue remote- access tools) and correlate them with binaries, users, startup mechanisms, and timestamps. The command netstat -tulpnis designed for exactly this purpose. In this switch set:-tlimits output to TCP sockets,-uincludes UDP sockets,-lshows only listening sockets (open ports awaiting connections),-pdisplays the owningprocess name and PID, and-nprevents name resolution by showing numeric IP addresses and ports (faster and avoids altering evidence via DNS queries). This combination yields a concise list of active listening ports and the processes bound to them, which is highly valuable for detecting unexpected services and attributing network exposure to a specific executable.
The other options do not provide process-to-port attribution:netstat -ishows interface statistics,ip rshows the routing table, andnetstat -rndisplays the routing table in numeric form. Therefore, the correct command is netstat -tulpn(D).

NEW QUESTION # 18
Kane, an investigation specialist, was appointed to investigate an incident in an organization's network. In this process, Kane executed a command and identified that a network interface is running in the promiscuous mode and is allowing all incoming packets without any restriction.
In the above scenario, which of the following commands did Kane use to check whether the network interface is set to the promiscuous mode?

A. ipconfig <interface name>
B. netstat -i
C. ifconfig <interface name>
D. nmap -sT localhost

Answer: C

Explanation:
Promiscuous mode is a network interface configuration in which the NIC passesall observed framesto the operating system, not only frames addressed to that host's MAC address. In investigations, this matters because promiscuous mode is commonly enabled bypacket sniffers, certain intrusion tools, or misconfigured monitoring software, and it can indicate covert traffic capture on a host.
On UNIX/Linux systems, the traditional command used to view interface flags and status isifconfig < interface name>. When an interface is set to promiscuous mode,ifconfigdisplays aPROMISCflag in the interface's status line, allowing an investigator to confirm whether the NIC is accepting all frames. This directly matches Kane's goal of checking if the interface is running in promiscuous mode.
The other commands do not provide this specific interface flag.nmap -sT localhostscans for open TCP ports, not interface modes.ipconfigis a Windows command (and does not take an interface name in that form to show PROMISC status), and it primarily reports IP configuration.netstat -ishows network interface statistics (packets, errors, drops) but typically does not explicitly indicate promiscuous mode. Therefore, the correct command isifconfig <interface name> (C).

NEW QUESTION # 19
Which of the following NTFS system files contains a record of every file present in the system?

A. $mft
B. $quota
C. $logfile
D. $volume

Answer: A

Explanation:
In the NTFS file system, theMaster File Table (MFT)is the core metadata structure that tracksevery file and directoryon the volume. NTFS implements this as a special system file named$MFT(shown here as$mft).
Each file or folder on an NTFS partition is represented by at least oneMFT record entry, which stores essential metadata such as file name(s), timestamps, security identifiers/ACL references, file size, attributes, and pointers to the file's data runs (or, for very small files, the content can be stored resident inside the record). Because it is the authoritative "index" of file objects, forensic examiners rely heavily on $MFT to reconstruct user activity and file history, including evidence of deleted files (when records are marked unused but remnants of attributes may remain) and timeline building from timestamp attributes.
The other options are different NTFS metadata files with narrower purposes:$LogFilerecords NTFS transaction logs to support recovery,$Volumestores volume-level information (like version/label), and$Quotamanages disk quota tracking. None of these contain a record for every file on the system.
Therefore, the NTFS system file that contains a record of every file present is$mft (B).

NEW QUESTION # 20
Identify the investigation team member who is responsible for evidence gathered at the crime scene and maintains a record of the evidence, making it admissible in a court of law.

A. Evidence manager
B. Incident analyzer
C. Evidence examiner
D. Incident responder

Answer: A

Explanation:
The role described-being responsible for evidence gathered at the crime scene and maintaining a record that makes the evidence admissible in court-matches the duties of anEvidence manager. In digital forensics practice, admissibility depends heavily on provingintegrity, authenticity, and continuity of possession. The evidence manager ensures these requirements by implementing and documenting thechain of custody, which is the formal, chronological record of who collected the evidence, when and where it was collected, how it was packaged and labeled, how it was transported, where it was stored, and every time it was accessed or transferred. This role also enforces evidence handling procedures such as tamper-evident sealing, secure storage controls, access logging, and verification steps (for example, ensuring hashes are recorded and preserved for forensic images).
Anincident responderfocuses on containment and immediate actions during an incident; anincident analyzerperforms technical analysis and correlation of artifacts; and anevidence examinerconducts detailed forensic examinations on acquired data. While these roles interact with evidence, the specific responsibility for maintaining custody documentation and evidence records to support legal admissibility belongs to theEvidence manager, makingDthe correct answer.
