NEW QUESTION # 54
Below is an extracted Apache error log entry.
"[Wed Aug 28 13:35:38.878945 2020] [core:error] [pid 12356:tid 8689896234] [client 10.0.0.8] File not found: /images/folder/pic.jpg" Identify the element in the Apache error log entry above that represents the IP address from which the request was made.
Answer: A
Explanation:
Apache error logs record key metadata about server-side events in a structured format that is widely used in web attack investigations. In the provided entry, each bracketed field represents a specific attribute: the first bracket contains the timestamp, the next contains the module and severity (e.g.,core:error), then the process
/thread identifiers (pidandtid), followed by the client identifier. The client field is explicitly labeled[client ...], and it captures thesource IP address(or sometimes hostname) that initiated the HTTP request which resulted in the logged error.
Here,[client 10.0.0.8]indicates that the request originated from IP address10.0.0.8. This is the critical element investigators use to attribute suspicious activity (such as probing for missing files, scanning directories, or exploitation attempts) to a specific network source. The other values are not the client IP:13:35:38.878945is the time component of the timestamp,12356is the Apache process ID, and8689896234is the thread ID handling the request. Therefore, the IP address from which the request was made is10.0.0.8 (C).
NEW QUESTION # 55
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 # 56
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.
Answer: B
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 # 57
Which of the following data acquisition formats supports the Lempel-Ziv-Markov chain (LZMA) algorithm for compression?
Answer: B
Explanation:
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.
NEW QUESTION # 58
Benoy, a security professional at an organization, extracted Apache access log entries to view critical information about all the operations performed on a web server. The Apache access log extracted by Benoy is given below:
"10.10.10.10 - Jason [17/Aug/2019:00:12:34 +0300] "GET /images/content/bg_body_1.jpg HTTP/1.0" 500
1458"
Identify the HTTP status code in the Apache access log entry above that indicates the response was successful.
Answer: D
Explanation:
In the Apache Combined/Custom access log format, the value immediately after the quoted request (here," GET ... HTTP/1.0") is theHTTP status codereturned by the server. In the provided entry, that field is500.
From a forensic analysis standpoint, recognizing field positions matters because investigators correlate client IPs, timestamps, requested resources, and server outcomes to reconstruct attack timelines and identify failed exploitation attempts or misconfigurations.
It is important to note thatsuccessful HTTP responses are typically in the 2xx range, most commonly200 (OK), while3xxindicates redirects,4xxindicates client-side errors (such as 404 Not Found), and5xxindicates server-side failures. Specifically,500represents anInternal Server Error, meaning the server encountered an unexpected condition and could not fulfill the request successfully.
The other options are not HTTP status codes in this entry:+0300is the timezone offset in the timestamp,1.0is the HTTP protocol version, and2019is part of the date. Therefore, the only HTTP status code present-and the correct choice among the options-is500 (B), even though it reflects an error rather than success.
