質問 # 18
Which of the following data acquisition formats supports the Lempel-Ziv-Markov chain (LZMA) algorithm for compression?
正解：D
解説：
In digital forensics, acquisition formats differ mainly in how they store evidence data, metadata, and whether they support features like compression, segmentation, and integrity verification. ARaw formatis a sector-by- sector bitstream image (often called "dd" style) and typically doesnotdefine built-in compression or structured metadata; any compression would be external to the format. "Proprietary format" is not a single defined standard-some proprietary images may compress data, but the option is too generic and not tied to a specific, documented compression method.
The format known in forensic documentation for explicitly supporting modern compression such asLZMAisAFF4 (Advanced Forensic Format 4), which is designed as a next-generation container supporting rich metadata, hashing, chunked storage, and pluggable compression options. AFF4's architecture stores evidence in compressed chunks/streams and commonly associates LZMA with efficient, high-ratio compression while preserving forensic requirements such as repeatable verification through cryptographic hashes.
The option "Advanced ForensicFramework 4" corresponds toAFF4in many exam question banks and training materials. Therefore, the correct choice isC, because AFF4 is the acquisition format recognized for supportingLZMA compressionas part of its standardized capabilities.
質問 # 19
Wesley, a professional hacker, deleted a confidential file in a compromised system using the "/bin/rm/" command to deny access to forensic specialists.
Identify the operating system on which Don has performed the file carving act.
正解：A
解説：
The command path /bin/rm is a hallmark of UNIX/POSIX-style operating systems, where core userland utilities are commonly stored under directories such as /bin, /sbin, and /usr/bin. The utility rm (remove) is the standard UNIX command used to delete directory entries that reference a file's data blocks on disk. This layout and command structure do not match Windows, whichuses different filesystem conventions (drive letters, backslashes, and Windows-native executables) and does not provide /bin/rm as a native path. Android, while Linux-kernel-based, typically exposes shell utilities through environments like /system/bin (and newer systems may use toybox/busybox variants), not the classic /bin hierarchy expected on general-purpose UNIX systems. Between the remaining options, both Linux and macOS are UNIX-like and can include an rm command; however, in digital forensics training and examination contexts, the explicit reference to /bin/rm is most commonly used to indicate a Linux/UNIX command-line environment on a compromised host.
Therefore, the best single-choice answer from the provided options is Linux (D).
質問 # 20
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?
正解：C
解説：
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).
質問 # 21
Which of the following Tor relay nodes in the Tor circuit is designed to transfer data in an encrypted format?
正解：D
解説：
In a standard Tor circuit, a client typically builds a three-hop path:Entry/Guard # Middle # Exit. Tor uses onion routing, where the client wraps the payload in multiple encryption layers-one for each hop. Each relay removes (decrypts) only its own layer to learn thenext hop, but not the complete route or the original payload in the clear. Themiddle relayis specifically positioned toforward traffic between the entry/guard and the exit while it remains onion-encrypted end-to-end within the Tor network. Because it neither connects to the user's local network (like the entry/guard) nor to the public destination (like the exit), its primary role isencrypted transit/forwarding, helping break the linkage between source and destination. By contrast, theexit relayis where traffic leaves Tor; unless the application layer uses TLS/HTTPS, the exit may deliver data to the destination inunencryptedform on the open Internet. Theentry/guardprotects against certain traffic-correlation risks by being stable, but it is not uniquely "the" encrypted-transfer node. Therefore, the best single answer isMiddle relay (D).
質問 # 22
Given below are different steps involved in event correlation.
Event masking
Event aggregation
Root cause analysis
Event filtering
Identify the correct sequence of steps involved in event correlation.
正解：B
解説：
In event correlation (as applied in SOC/SIEM-driven investigations), the workflow typically starts byreducing complexityandnormalizing what "one incident" looks likebefore attempting conclusions about causality.Event aggregation (2)is performed early to combine multiple low-level, related events (for example repeated authentication failures, repeated firewall denies, or multiple IDS hits for the same signature) into higher-level
"grouped" records. This prevents analysts from treating every raw log line as a separate incident and makes correlation computationally and operationally feasible.
Next,event masking (1)suppresses events that are already known to be irrelevant or repetitive in a way that does not add investigative value (for example, routine scheduled scans, approved admin tools, or duplicate alerts already represented in the aggregated set). After masking,event filtering (4)further removes remaining noise using rules, thresholds, whitelists, time windows, or relevance criteria (scope, asset criticality, and known-benign sources), leaving a cleaner dataset that represents probable security-relevant activity.
Only after the dataset is consolidated and noise-reduced doesroot cause analysis (3)become reliable, because RCA depends on a clear chain of correlated events to identify the initiating action and propagation path.
Hence the correct sequence is2 # 1 # 4 # 3 (Option B).
