NEW QUESTION # 14
Below is the syntax of a command-line utility that displays active TCP connections and ports on which the computer is listening.
netstat [-a] [-e] [-n] [-o] [-p Protocol] [-r] [-s] [Interval]
Identify the netstat parameter that displays active TCP connections and includes the process ID (PID) for each connection.
- A. [-o]
- B. [-s]
- C. [-n]
- D. [-a]
Answer: A
Explanation:
In Windows forensics and incident response, investigators often need to linknetwork activity(remote IPs, ports, connection states) to theresponsible processto determine whether traffic is legitimate or associated with malware, unauthorized tools, or data exfiltration. The Windowsnetstatutility can enumerate current TCP connections and listening ports, but the key flag that enables attribution to a running program is-o. The-o parameter instructs netstat to include theOwning Process ID (PID)with each connection or listening socket.
Once the PID is known, examiners can correlate it with process listings (e.g., Task Manager,tasklist, memory forensics output) to identify the executable name, path, user context, and parent process-critical steps in reconstructing attacker behavior and persistence.
The other options do not provide PID mapping:-nshows addresses and ports in numeric form (useful for speed and to avoid DNS lookups),-adisplays all connections and listening ports but without PID attribution by itself, and-sshows protocol statistics rather than per-connection ownership. Therefore, the parameter that shows active connectionsandincludes the PID for each is[-o](Option C).
NEW QUESTION # 15
David, a cybercriminal, targeted a community and initiated anti-social campaigns online. In this process, he used a layer of the web that allowed him to maintain anonymity during the campaign.
Which of the following layers of the web allowed David to hide his presence during the anti-social campaign?
- A. Dark Web
- B. World Wide Web
- C. Deep Web
- D. Surface Web
Answer: A
Explanation:
The layer of the web most associated withmaintaining anonymityfor users and services is theDark Web. In digital forensics terminology, the Dark Web refers to services hosted on overlay networks (such as Tor hidden services) that arenot indexed by standard search enginesand are typically accessible only through specialized software and configurations. Its core characteristic is that it is deliberately designed to reduce traceability by routing traffic through multiple relays and separating identifying information (like the user's real IP address) from the destination. This makes attribution and geolocation significantly harder using traditional network logs alone, which is why adversaries often choose it to conduct covert communications, host content, or coordinate campaigns.
By contrast, theSurface Web(the regular, indexed portion of the web) is generally reachable through normal browsers and is easier to monitor and attribute using conventional ISP, server, and platform logs. "World Wide Web" is a general term for web content accessed via HTTP/HTTPS and does not specifically imply anonymity. TheDeep Webrefers to content not indexed by search engines (e.g., webmail, databases, authenticated portals), but it is not inherently anonymizing-many deep web resources are simply private or access-controlled. Therefore, the layer enabling David to hide his presence is theDark Web (C).
NEW QUESTION # 16
Which of the following file systems of Windows replaces the first letter of a deleted file name with the hex byte code "e5h"?
- A. EFS
- B. FHS
- C. FAT
- D. NTFS
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 # 17
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.
- A. ProcDump
- B. ESEDatabaseView
- C. DriveLetterView
- D. PromiscDetect
Answer: C
NEW QUESTION # 18
Below are the elements included in the order of volatility for a typical computing system as per the RFC 3227 guidelines for evidence collection and archiving.
Archival media
Remote logging and monitoring data related to the target system
Routing table, process table, kernel statistics, and memory
Registers and processor cache
Physical configuration and network topology
Disk or other storage media
Temporary system files
Identify the correct sequence of order of volatility from the most to least volatile for a typical system.
- A. 7-->5-->4-->3-->2-->6-->1
- B. 4-->3-->7-->1-->2-->5-->6
- C. 4-->3-->7-->6-->2-->5-->1
- D. 2-->1-->4-->3-->6-->5-->7
Answer: C
Explanation:
RFC 3227's "order of volatility" principle guides responders to collect themost perishableevidence first because some data can disappear immediately when power is lost, processes terminate, or the system state changes during response actions. The most volatile items areCPU registers and processor cache (4)because they change continuously at instruction speed and are lost instantly on shutdown or context switching. Next arerouting table, process table, kernel statistics, and memory (3)because live RAM contents and active system tables can change within seconds and are lost if the machine is powered off or rebooted.
After volatile memory,temporary system files (7)are collected because they are frequently overwritten or cleaned by the OS, users, or malware. Then comesdisk or other storage media (6)which is more persistent but still subject to modification, log rotation, and overwriting through normal activity; hence imaging should occur before extensive interaction.
Less volatile still areremote logging and monitoring data (2)since they may persist off-host, but can be rotated or altered by retention policies.Physical configuration and network topology (5)generally changes less frequently and can often be re-documented later. Finally,archival media (1)is the least volatile because it is typically write-once or preserved storage. Thus the correct sequence is4#3#7#6#2#5#1 (Option B).
NEW QUESTION # 19
Williams, a forensic specialist, was tasked with performing a static malware analysis on a suspect system in an organization. For this purpose, Williams used an automated tool to perform a string search and saved all the identified strings in a text file. After analyzing the strings, he determined all the harmful actions that were performed by malware.
Identify the tool employed by Williams in the above scenario.
- A. R-Drive Image
- B. ResourcesExtract
- C. Ezvid
- D. Snagit
Answer: B
Explanation:
Instatic malware analysis, one of the quickest ways to infer capability is to extract and reviewstringsembedded in a binary. Strings frequently reveal command-and-control domains/IPs, mutex names, file paths, registry keys, user-agent values, suspicious commands (PowerShell/cmd), API names, error messages, encryption markers, and configuration fragments. Investigators often use automated utilities to extract these readable artifacts andexport them to a text filefor later triage, keyword searching, and correlation with other evidence (network logs, endpoint telemetry, and threat intel).
Among the provided options,ResourcesExtractbest matches this workflow. It is designed to extract embedded content from executable files-particularly Windows PE resources-and can export extracted textual items (including resource strings/strings tables and related embedded text) into external files for analysis. This aligns with "performed a string search and saved all the identified strings in a text file." The other choices do not fit:R-Drive Imageis a disk imaging/backup tool;Ezvidis for screen recording; andSnagitis for screenshots/screen capture. They do not perform automated extraction of strings from malware binaries as a static-analysis step. Therefore, the correct answer isResourcesExtract (B).
NEW QUESTION # 20
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?
- A. Local and online malware scanning
- B. File fingerprinting
- C. Strings search
- D. Malware disassembly
Answer: B
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).
NEW QUESTION # 21
Kelly, a professional hacker, used her laptop to perform illegal cyber activities for monetary gain on many victims. She securely locked her laptop using BitLocker software. Using this tool, she locked an entire volume using a secret key to deny access to the system.
Identify the anti-forensic technique used by Don in the above scenario.
- A. Trail obfuscation
- B. Artifact wiping
- C. File carving
- D. Encryption
Answer: D
Explanation:
The scenario describes the use ofBitLockerto lock an entire disk volume with asecret key, preventing access to the contents. In digital forensics, this is a classic example ofencryption as an anti-forensics technique. Full- disk or full-volume encryption transforms readable data into ciphertext using cryptographic algorithms so that, without the correct key (password, recovery key, TPM-bound protector, etc.), the data is computationally infeasible to interpret. This directly obstructs evidence acquisition and analysis because a forensic image of the drive will largely contain encrypted blocks rather than interpretable file system structures and user data.
This differs from the other options:file carvingis a forensic recovery method (often used by investigators) that reconstructs files from unallocated space; it is not an anti-forensics method used to block access.Artifact wipingattempts to erase traces by deleting or overwriting files, logs, or free space, but it does not inherently prevent access to remaining data if wiping is incomplete.Trail obfuscationinvolves misleading or altering logs and traces to confuse investigators, whereas encryption primarilydenies content visibilityby design. Because BitLocker is explicitly a volume encryption mechanism used here to deny access, the correct anti-forensic technique isEncryption (D).
NEW QUESTION # 22
A forensic investigator is collecting volatile data such as system information and network information present in the registries, cache, DLLs, and RAM of digital devices through its normal interface.
Identify the data acquisition method the investigator is performing.
- A. Dead acquisition
- B. Static acquisition
- C. Non-volatile data acquisition
- D. Live acquisition
Answer: D
Explanation:
The scenario describes the investigator collectingvolatileartifacts-specifically information inRAM, activeDLLs, system and network state, and transient data held incacheand similar runtime locations-through the device's normal interface while the system is running. In digital forensics documentation, this is the defining characteristic oflive acquisition(also called live response). Live acquisition is performed when the system remains powered on so that investigators can capture evidence that would be lost on shutdown, such as running processes, open network connections, logged-on sessions, loaded modules/DLLs, encryption keys, and portions of registry data that exist in memory or are actively changing.
By contrast,static acquisitionanddead acquisitionare conducted when the system is powered off (or the evidence drive is imaged outside the running OS), focusing primarily on persistent storage such as disk sectors and file system structures.Non-volatile data acquisitionrefers to collecting persistent data stored on media (e.g., files on disk), which does not match the emphasis on RAM and other volatile components in the question. Because the investigator is explicitly collecting volatile data from a running system via its normal interface, the correct method isLive acquisition (B).
NEW QUESTION # 23
John, a forensic officer, was working on a criminal case. He employed imaging software to create a copy of data from the suspect device on a storage medium for further investigation. For developing an image of the original data, John used a software application that does not allow an unauthorized user to alter the image content on storage media, thereby retaining an unaltered image copy.
Identify the data acquisition step performed by John in the above scenario.
- A. Sanitized the target media
- B. Enabled write protection on the evidence media
- C. Validated data acquisition
- D. Planned for contingency
Answer: B
Explanation:
The scenario emphasizes that John used an application (or mechanism) thatprevents alteration of the acquired image content, ensuring the image remainsunalteredand protected from unauthorized modification. In forensic acquisition standards, this corresponds toenabling write protectionduring imaging-commonly implemented using awrite blocker(hardware or controlled software write-protection) to prevent any writes to the source evidence and, where applicable, to protect the integrity of the evidence copy from accidental or unauthorized changes. The purpose is to preserve evidential integrity by ensuring that neither the original media nor the forensic image is modified during handling, analysis preparation, or transfer.
"Validated data acquisition" refers to confirming the image is an exact duplicate, typically by computing and comparing cryptographic hashes (e.g., MD5/SHA) of the source and the acquired image. While validation is essential, the question specifically highlightspreventing alteration, not verifying equality. "Sanitized the target media" is the step of wiping/clearing the destination drive before acquisition to avoid contamination, which is not what is described. "Planned for contingency" relates to operational planning for unexpected issues (equipment failure, encryption, power loss), not integrity protection. Therefore, the best match isEnabled write protection on the evidence media (A).
NEW QUESTION # 24
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.
- A. Linux
- B. Android
- C. Mac OS
- D. Windows
Answer: A
Explanation:
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).
NEW QUESTION # 25
Harry, a security professional, was hired to identify the details of an attack that was initiated on a Windows system. In this process, Harry decided to check the logs of currently running applications and the information related to previously uninstalled or removed applications for suspicious events.
Which of the following folders in a Windows system stores information on applications run on the system?
- A. C:\Windows\Prefetch
- B. C:\subdir
- C. C:\Windows\Book
- D. C:\Windows\debug
Answer: A
Explanation:
On Windows systems, thePrefetchfeature records execution-related artifacts to speed up subsequent program launches. When an executable is run, Windows often creates a.pf prefetch fileinC:\Windows\Prefetchthat contains valuable forensic indicators such as the executable name (mapped into the prefetch filename), last run time(s) (depending on Windows version), run count (in many versions), and a list of files and directories referenced during startup. Because these artifacts can persist even after an application is lateruninstalled or deleted, investigators commonly use the Prefetch directory to demonstrate that a program executed on a host and to help build timelines around suspicious activity. This is especially useful in intrusion investigations for identifying the execution of attacker tools, droppers, scripts launched via interpreters, or renamed binaries.
The other options are not standard repositories for program execution history.C:\Windows\debugmay contain specific debug logs for certain components but is not the canonical execution-tracking folder.C:
\Windows\BookandC:\subdirare not standard Windows forensic artifact locations. Therefore, the folder that stores information on applications run on the system isC:\Windows\Prefetch (C).
NEW QUESTION # 26
Which of the following commands can an investigator use to parse GPTs of both types of hard disks, including those formatted with either UEFI or MBR?
- A. Get-GPT
- B. Get-BootSector
- C. Get-PartitionTable
- D. Get-ForensicPartitionTable
Answer: D
Explanation:
In forensic examinations, investigators must correctly interpret a disk'spartitioning schemebecause it determines where volumes begin, where file systems reside, and how to validate acquisition completeness.
Modern systems may useGPT(commonly associated with UEFI) while legacy systems often useMBR. A practical forensic command therefore needs to detect and parse partition informationregardless of whether the disk uses MBR or GPT, and present the results in a consistent, investigator-friendly output for verification and downstream analysis (e.g., selecting the correct partition offsets for imaging or mounting).
Get-ForensicPartitionTableis designed for exactly this role in forensic PowerShell tooling: it parses partition table structures in a forensically oriented manner and supports disks partitioned usingeither MBR or GPT.
That "forensic" emphasis typically means it reads raw structures directly, reports partition entries and offsets, and helps avoid ambiguity when the protective MBR (present on GPT disks) could confuse simplistic parsers.
By contrast,Get-BootSectortargets boot sector/VBR data rather than the full partition layout;Get-GPTis GPT- specific and does not cover MBR-only disks; andGet-PartitionTableis a more generic label that may not guarantee dual-scheme forensic parsing. Therefore, the correct option isC.
NEW QUESTION # 27
Bob, a forensic investigator, is investigating a live Windows system found at a crime scene. In this process, Bob extracted subkeys containing information such as SAM, Security, and software using an automated tool called FTK Imager.
Which of the following Windows Registry hives' subkeys provide the above information to Bob?
- A. HKEY_LOCAL_MACHINE
- B. HKEY_CLASSES_ROOT
- C. HKEY_CURRENT_CONFIG
- D. HKEY_CURRENT_USER
Answer: A
Explanation:
In Windows forensics, the Registry is organized into logical root keys ("hives") that aggregate configuration and security data. The items named in the question-SAM,SECURITY, andSOFTWARE-aresystem-wide registry hivesstored on disk (typically under the system's configuration directory) and loaded at runtime underHKEY_LOCAL_MACHINE (HKLM). Investigators rely on these hives because they contain high- value evidence: theSAMhive stores local account database information (including user and group identifiers and credential-related material), theSECURITYhive holds system security policy and LSA-related settings, and theSOFTWAREhive contains installed software, application configuration, and many operating system settings relevant for program execution and persistence analysis.
Tools likeFTK Imagercan extract these hives (or their live-memory representations) during triage to preserve volatile context and enable offline parsing while maintaining evidentiary integrity. The other root keys do not match these specific hives:HKEY_CURRENT_USERis per-user profile data, HKEY_CURRENT_CONFIGreflects current hardware profile, andHKEY_CLASSES_ROOTis primarily file association/COM class mapping (largely derived from HKLM\Software\Classes and HKCU\Software\Classes). Therefore, the correct hive root that provides SAM, SECURITY, and SOFTWARE subkeys isHKEY_LOCAL_MACHINE (B).
NEW QUESTION # 28
Which of the following techniques is defined as the art of hiding data "behind" other data without the target's knowledge, thereby hiding the existence of the message itself?
- A. Program packer
- B. Steganography
- C. Password cracking
- D. Artifact wiping
Answer: B
Explanation:
Steganographyis the technique of concealing a messagewithin another seemingly harmless carrier(such as an image, audio file, video, or document) so that theexistence of the hidden message is not apparentto an observer. Digital forensics references distinguish steganography from encryption: encryption scrambles content but usually leaves visible indicators that protected data exists (ciphertext), while steganography aims to make the communication look ordinary, reducing suspicion. In practice, steganographic methods often embed data into redundant or less perceptible parts of the carrier, such as modifying least significant bits in pixel values, altering frequency components in audio, or inserting data into metadata or unused file structures.
The other options do not match the definition.Password crackingis an access technique to recover authentication secrets, not a concealment method.Artifact wipingis an anti-forensics method intended to remove traces (logs, files, slack space remnants), but it does not "hide behind" other data-it destroys or overwrites evidence.Program packerscompress/obfuscate executables to hinder static analysis and detection, but they still produce an executable whose presence is evident; they do not primarily hide messages inside benign files. Therefore, the described "hiding the existence of the message itself" corresponds toSteganography (C).
NEW QUESTION # 29
Cheryl, a forensic expert, was recruited to investigate a malicious activity performed by an anonymous hackers' group on an organization's systems. Using an automated tool, Cheryl was able to extract the malware file and analyze the assembly code instructions, which helped him understand the malware's purpose.
Which of the following tools helped Cheryl extract and analyze the assembly code of the malware?
- A. OllyDbg
- B. Virtual Box
- C. QualNet
- D. VMware vSphere
Answer: A
Explanation:
To understand a malware sample's purpose at the instruction level, investigators usereverse-engineering toolsthat candisassemblecompiled binaries intoassembly codeand often allowinteractive debuggingto observe runtime behavior (API calls, unpacking routines, decryption loops, process injection, and control-flow decisions).OllyDbgis a classic Windows user-mode debugger widely referenced in malware analysis workflows because it provides an integrated view ofdisassembly, CPU registers, memory, breakpoints, and execution tracing. This makes it suitable for extracting behavioral insight from the actual assembly instructions, especially when malware uses obfuscation or packers that require stepping through execution to reach the real payload.
The other options do not primarily perform assembly-level analysis.VirtualBoxandVMware vSphereare virtualization platforms; they help safely run malware in isolated environments, but they are not disassemblers
/debuggers for examining assembly instructions.QualNetis a network simulation tool used for modeling network behavior, not binary reverse engineering. Because the question specifically emphasizesanalyzing assembly code instructionsto understand malware purpose, the correct tool among the choices isOllyDbg (C).
NEW QUESTION # 30
While investigating a web attack on a Windows-based server, Jessy executed the following command on her system:
C:> net view <\10.10.10.11>
What was Jessy's objective in running the above command?
- A. Check whether sessions have been opened with other systems
- B. Review file shares to ensure their purpose
- C. Check file space usage to look for a sudden decrease in free space
- D. Verify the users using open sessions
Answer: B
Explanation:
The Windowsnet view \\<computer>command is used to enumerateshared resources(SMB shares) that a remote Windows system is publishing. When Jessy runsnet view \\10.10.10.11, her goal is to retrieve a list of the target host's visible shares-such as administrative shares (e.g.,C$,ADMIN$) and any custom shares created for departments, applications, or users. In forensic and incident-response practice, this is important because attackers commonly use SMB shares forlateral movement,staging tools,dropping payloads, andexfiltrating data. By reviewing the shares exposed by a suspected server, the investigator can quickly identify unexpected or overly permissive shares, locate potential repositories of web content or logs, and determine whether a compromised web server is also exposing file resources that expand the attacker's options.
The other options map to different commands and artifacts: disk space usage is checked with storage utilities (notnet view), open sessions are examined with commands likenet session, and identifying users accessing files typically involvesnet fileor server auditing logs. Therefore, Jessy's objective was toreview file shareson the remote host.
NEW QUESTION # 31
Identify the malware analysis technique in which the investigators must take a snapshot of the baseline state of the forensic workstation before malware execution.
- A. String search
- B. Online malware scanning
- C. File fingerprinting
- D. Monitoring host integrity
Answer: D
Explanation:
The technique described-taking a snapshot of the baseline state of the forensic workstation before executing malware-aligns withMonitoring host integrity. In malware forensics, investigators often perform controlled execution (dynamic analysis) and need a reliable way to identifywhat changed on the systemas a direct result of the malware run. Host integrity monitoring is a structured approach where the examiner first captures aknown-good baselineof critical system elements such as file system state (key directories, system binaries), registry/configuration state, running services, installed drivers, scheduled tasks, and sometimes hash inventories of important files. After malware execution, the investigator captures a second snapshot and performsdifferential comparisonto determine newly created/modified files, persistence mechanisms, configuration changes, dropped payloads, and tampering attempts.
This baseline-before/after comparison is fundamental for attributing changes to the sample, supporting repeatability, and documenting evidence in a defensible manner. The other options do not require a workstation baseline snapshot in this sense:online malware scanningchecks a file against signatures/reputation services;string searchextracts readable strings from binaries; andfile fingerprintingtypically refers to hashing to uniquely identify a file, not system-wide state comparison. Therefore, the correct answer isMonitoring host integrity (B).
NEW QUESTION # 32
Bob, a network specialist in an organization, is attempting to identify malicious activities in the network. In this process, Bob analyzed specific data that provided him a summary of a conversation between two network devices, including a source IP and source port, a destination IP and destination port, the duration of the conversation, and the information shared during the conversation.
Which of the following types of network-based evidence was collected by Bob in the above scenario?
- A. Full content data
- B. Statistical data
- C. Alert data
- D. Session data
Answer: D
Explanation:
The description matchessession data, often calledflow records(for example, NetFlow/IPFIX-style evidence).
In network forensics, session/flow evidence summarizes a communication "conversation" between two endpoints using the5-tuple(source IP, source port, destination IP, destination port, and protocol) and typically addsstart/end time or duration,bytes/packets sent, and sometimes directionality. This allows an investigator to reconstructwho talked to whom, when, and for how long, even when packet payloads are unavailable (because of encryption, storage limits, or privacy constraints).
"Full content data" refers to complete packet captures (PCAP) containing payload bytes; that is far more detailed and would include the actual transmitted content, not just a summary. "Statistical data" is broader aggregate metrics (overall bandwidth trends, interface counters) and generally lacks per-conversation attribution. "Alert data" comes from IDS/IPS/SIEM detections and represents triggered events or signatures, not a neutral conversation summary.
Because Bob's evidence contains per-connection identifiers (IPs/ports) and conversation duration-typical of flow/session summaries-the correct evidence type isSession data (C).
