NEW QUESTION # 71
Below are the various steps involved in an email crime investigation.
1.Acquiring the email data
2.Analyzing email headers
3.Examining email messages
4.Recovering deleted email messages
5.Seizing the computer and email accounts
6.Retrieving email headers
What is the correct sequence of steps involved in the investigation of an email crime?
Answer: A
Explanation:
In an email crime investigation, the workflow should begin withseizing the computer and email accounts (5)to preserve evidence and prevent alteration, deletion, or continued misuse. This includes securing endpoints and ensuring account access is maintained under proper authority. Next, investigators proceed withacquiring the email data (1)using forensic methods (logical export, mailbox acquisition, or forensic imaging of local mail stores) to maintain integrity and chain of custody.
Once the data is preserved, investigatorsexamine email messages (3)to identify relevant communications, context, attachments, and indicators of fraud, harassment, data leakage, or impersonation. After identifying emails of interest, investigatorsretrieve email headers (6)(full headers, not just what the mail client displays) because headers contain routing metadata required for attribution and timeline reconstruction. They thenanalyze email headers (2)to interpret fields such as Received lines, Message-ID, originating IP clues (where applicable), sending infrastructure, and authentication results, which helps determine spoofing, relay paths, and sender legitimacy. Finally, theyrecover deleted email messages (4)from mail stores, server-side retention, or unallocated space to restore missing evidence. This sequence matches optionA.
NEW QUESTION # 72
A disk drive has 16,384 cylinders, 80 heads, and 63 sectors per track, and each sector can store 512 bytes of data.
What is the total size of the disk?
Answer: C
Explanation:
In classic hard-disk geometry, total capacity is computed fromCHS parameters(Cylinders × Heads × Sectors per track) multiplied bybytes per sector. Forensic examiners learn this because it helps validate whether an image acquisition size is consistent with the physical disk geometry and to spot anomalies caused by misreported device geometry or capture errors.
First compute total addressable sectors:
16,384 cylinders × 80 heads = 1,310,720 tracks(because each head provides a track per cylinder).
Then multiply by sectors per track:
1,310,720 × 63 = 82,575,360 sectors.
Convert sectors to bytes using the sector size:
82,575,360 sectors × 512 bytes/sector = 42,278,584,320 bytes.
This matches optionAexactly. In practice, modern drives often use LBA and may report different logical geometries, but the forensic principle remains the same: capacity equals the number of logical blocks times the logical block size, and CHS-style values are a structured way to perform that verification.
NEW QUESTION # 73
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: A
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 # 74
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.
Answer: D
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 # 75
A system that a cybercriminal was suspected to have used for performing an anti-social activity through the Tor browser. James reviewed the active network connections established using specific ports via Tor.
Which of the following port numbers does Tor use for establishing a connection via Tor nodes?
Answer: A
Explanation:
In Tor Browser deployments, Tor typically runs a local client ("tor" process) that exposes aSOCKS proxyfor applications (the browser) to send traffic into the Tor network and, optionally, acontrol interfacefor managing circuits and obtaining runtime status. In many forensic lab guides and Tor Browser bundle configurations, the default local SOCKS listening port is9150, and the associated Tor control port is commonly9151. This pairing is frequently referenced in investigations because endpoint triage (e.g., netstat outputs, firewall logs, EDR socket telemetry) may show local loopback connections from the browser to127.0.0.1:9150(SOCKS) and management communications involving9151(control).
From a network-forensics viewpoint, these ports help distinguish Tor Browser activity from other proxy tools:
the browser does not directly connect to Tor relays; instead, it hands traffic to the local SOCKS proxy, which then establishes encrypted circuits to Tor nodes. While Tor can be configured to use different ports, the question asks about the specific ports used for establishing Tor connections in typical Tor Browser setups, which aligns with9150/9151. Therefore, the correct option isD.
