Question 1
When an investigator contacts by telephone the domain administrator or controller listed by a Who is lookup to request all e-mails sent and received for a user account be preserved, what U.S.C. statute authorizes this phone call and obligates the ISP to preserve e-mail records?
- A. Title 18, Section 1030
- B. Title 18, Section 2703(d)
- C. Title 18, Section Chapter 90
- D. Title 18, Section 2703(f)
Correct Answer:
D
Explanation:
The AI agrees with the suggested answer of D. Title 18, Section 2703(f).
Reasoning: Title 18, Section 2703(f) of the United States Code specifically addresses the preservation of data by a provider of electronic communication service or remote computing service. When a governmental entity requests such preservation, the provider must comply, making this the correct answer. This section allows investigators to request ISPs to preserve email records.
Reasons for excluding other options:
- A. Title 18, Section 1030: This section deals with fraud and related activity in connection with computers. While it covers computer crimes, it doesn't specifically authorize an investigator to request the preservation of email records via a phone call, nor does it obligate the ISP based solely on a phone call.
- B. Title 18, Section 2703(d): This section outlines the requirements for a court order to disclose contents of electronic communications. While it is related to electronic communications, it does not directly address preservation requests made by investigators via telephone.
- C. Title 18, Section Chapter 90: This chapter generally covers protection of trade secrets. It does not directly authorize the preservation of email records in the context described in the question.
In summary, Title 18, Section 2703(f) is the most appropriate answer because it explicitly covers preservation requests made to ISPs.

Question 2
Item 2If you come across a sheepdip machine at your client site, what would you infer?
- A. A sheepdip coordinates several honeypots
- B. A sheepdip computer is another name for a honeypot
- C. A sheepdip computer is used only for virus-checking.
- D. A sheepdip computer defers a denial of service attack
Correct Answer:
C
Explanation:
The AI agrees with the suggested answer.
The suggested answer is C: A sheepdip computer is used only for virus-checking.
Reasoning: A sheepdip machine is a specialized computer used to scan files and removable media for malware before they are allowed to be used on a more secure network. Its primary, and often sole, purpose is virus checking. This prevents potentially infected files from compromising the network.
Reasons for not choosing the other options:
- A: A sheepdip does not coordinate honeypots. Honeypots are decoy systems, and sheepdips serve a different function which is malware scanning.
- B: A sheepdip computer is not another name for a honeypot.
- D: A sheepdip does not defer a denial-of-service attack. Its purpose is malware scanning.
-
Question 3
In a computer forensics investigation, what describes the route that evidence takes from the time you find it until the case is closed or goes to court?
- A. rules of evidence
- B. law of probability
- C. chain of custody
- D. policy of separation
Correct Answer:
C
Explanation:
The AI agrees with the suggested answer. The correct answer is C. chain of custody.
Reasoning: The chain of custody is a fundamental concept in forensics, particularly digital forensics. It meticulously documents the chronological sequence of custody, control, transfer, analysis, and disposition of evidence. This documentation is crucial for maintaining the integrity of evidence and ensuring its admissibility in court.
Why other options are incorrect:
- A. rules of evidence: These are legal principles that govern the admissibility of evidence in court, but they do not describe the route evidence takes.
- B. law of probability: This is a mathematical concept used to assess the likelihood of events, and it is not directly related to evidence handling.
- D. policy of separation: This is not a standard term used in computer forensics. It might vaguely refer to segregation of duties, but it doesn't define the route evidence takes.
The chain of custody is a critical process in digital forensics because it maintains the integrity of the evidence, ensuring it is admissible in court. Any break in the chain of custody can cast doubt on the authenticity and reliability of the evidence, potentially leading to its exclusion from legal proceedings.
-
Ensures evidence integrity.
-
Maintains credibility in court.
-
Provides a verifiable record of evidence handling.

Question 4
How many characters long is the fixed-length MD5 algorithm checksum of a critical system file?
Correct Answer:
C
Explanation:
The suggested answer is correct.
The MD5 algorithm produces a 128-bit hash value. This 128-bit value is typically represented as a 32-character hexadecimal string.
Therefore, the answer to the question "How many characters long is the fixed-length MD5 algorithm checksum of a critical system file?" is 32.
The other options are incorrect because:
- 128 represents the number of bits, not the number of characters in the hexadecimal representation.
- 64 and 16 are simply incorrect lengths for an MD5 hash in its typical hexadecimal representation.

Question 5
You are working on a thesis for your doctorate degree in Computer Science. Your thesis is based on HTML, DHTML, and other web-based languages and how they have evolved over the years.
You navigate to archive. org and view the HTML code of news.com. You then navigate to the current news.com website and copy over the source code. While searching through the code, you come across something abnormal: What have you found?
- A. Web bug
- B. CGI code
- C. Trojan.downloader
- D. Blind bug
Correct Answer:
A
Explanation:
The AI agrees with the suggested answer A (Web bug).
Reasoning: The question describes a scenario where someone is analyzing HTML code from different time periods and notices something abnormal in the current version. A web bug, also known as a tracking pixel, is a tiny, often invisible, image embedded in a web page or email. These bugs are used to track user behavior, such as whether an email has been opened or a web page has been visited. Given the context of analyzing the evolution of web technologies, encountering a tracking mechanism like a web bug when comparing modern and historical code would indeed be considered an anomaly or "something abnormal."
Why the other options are less likely:
- B. CGI code: CGI (Common Gateway Interface) code is used for server-side scripting, which handles interactions between the web server and external applications or databases. It is unlikely that CGI code would be directly embedded within the HTML source code in a way that would be considered an anomaly during a comparative analysis.
- C. Trojan.downloader: A Trojan downloader is a type of malware that downloads other malicious software onto a computer. While a website could potentially host or link to such malware, it is not something one would typically find directly embedded in the HTML source code during routine analysis.
- D. Blind bug: A "blind bug" is not a standard or well-known term in web development or security. It is not a recognized concept, and therefore an unlikely answer in this context.
The presence of a web bug is a plausible anomaly to encounter when comparing historical and modern HTML code, making option A the most fitting answer.

Question 6
You are using DriveSpy, a forensic tool and want to copy 150 sectors where the starting sector is 1709 on the primary hard drive. Which of the following formats correctly specifies these sectors?
- A. 0:1000, 150
- B. 0:1709, 150
- C. 1:1709, 150
- D. 0:1709-1858
Correct Answer:
B
Explanation:
The AI agrees with the suggested answer, B (0:1709, 150).
Reasoning:
The question states we are using DriveSpy to copy 150 sectors starting from sector 1709 on the primary hard drive. Based on the discussion and common forensic practices, the correct syntax for specifying sectors in DriveSpy is: [Drive Number]:[Starting Sector], [Number of Sectors].
- The primary hard drive is typically represented as drive 0.
- The starting sector is 1709, as given in the question.
- We need to copy 150 sectors.
Therefore, the correct format is 0:1709, 150.
Reasons for not choosing other options:
- A: 0:1000, 150 - Incorrect because the starting sector is 1709, not 1000.
- C: 1:1709, 150 - Incorrect because the primary hard drive is drive 0, not drive 1.
- D: 0:1709-1858 - Incorrect because this format specifies a range of sectors (1709 to 1858), not a starting sector and the number of sectors to copy. While 1709 + 150 -1 = 1858, the correct format is not a range.

- A. The attacker has conducted a network sweep on port 111
- B. The attacker has scanned and exploited the system using Buffer Overflow
- C. The attacker has used a Trojan on port 32773
- D. The attacker has installed a backdoor
Correct Answer:
A
Explanation:
The AI agrees with the suggested answer of A, "The attacker has conducted a network sweep on port 111".
Reasoning:
The provided Snort log excerpt shows the attacker's IP address (211.185.125.124) making connections to different IP addresses on the target network (172.16.1.108 and 172.16.1.103) on port 111 (sunrpc) and other ports. This behavior is indicative of a network sweep or port scan, where an attacker systematically probes multiple hosts and ports to identify potential vulnerabilities or open services. The initial connection to port 111 on 172.16.1.108, followed by UDP packets to port 111 on 172.16.1.103, and then another UDP packet to port 32773 on 172.16.1.103, supports this conclusion.
Reasons for not choosing other options:
- B. The attacker has scanned and exploited the system using Buffer Overflow: While possible, the log excerpt doesn't explicitly show a buffer overflow exploit attempt. The provided data focuses on the initial connection and scanning activity, not the exploitation phase.
- C. The attacker has used a Trojan on port 32773: The log shows traffic to port 32773, but there's no direct evidence of a Trojan being installed or used. Additional analysis of the packet content would be needed to confirm this.
- D. The attacker has installed a backdoor: Similar to option C, there's no explicit indication of a backdoor being installed in the given log excerpt. The log primarily showcases scanning activity.

Question 8
The newer Macintosh Operating System is based on:
- A. OS/2
- B. BSD Unix
- C. Linux
- D. Microsoft Windows
Correct Answer:
B
Explanation:
The AI agrees with the suggested answer, which is B: BSD Unix.
Reasoning: The newer Macintosh Operating System (macOS) is based on Darwin, which is itself based on BSD Unix. macOS's kernel, XNU, is a hybrid kernel that incorporates elements of BSD, Mach, and Apple's own I/O Kit. This makes BSD Unix the correct foundation for macOS.
Reasons for not choosing other options:
- A. OS/2: OS/2 was an operating system developed by IBM and Microsoft (later solely by IBM). It is not related to the macOS lineage.
- C. Linux: Linux is an open-source kernel that forms the basis of many operating systems, but it is not the foundation of macOS.
- D. Microsoft Windows: Microsoft Windows is a completely separate operating system family developed by Microsoft and has no connection to macOS.

Question 9
Before you are called to testify as an expert, what must an attorney do first?
- A. engage in damage control
- B. prove that the tools you used to conduct your examination are perfect
- C. read your curriculum vitae to the jury
- D. qualify you as an expert witness
Correct Answer:
D
Explanation:
The AI agrees with the suggested answer D.
Before an expert witness can testify, the attorney must first qualify the witness as an expert. This involves demonstrating to the court that the witness possesses the necessary knowledge, skills, experience, training, and education to provide expert testimony on a particular subject.
Reasoning:
The primary reason is to establish the expert's credibility and competence in the relevant field. Without proper qualification, the expert's testimony may be deemed inadmissible. The qualification process ensures that the court and jury can rely on the expert's opinions and interpretations.
- The attorney must establish the expert witness's qualifications in the relevant field before they can testify. This process is known as "qualifying" the expert witness, and it involves demonstrating their education, experience, skills, and training in the subject matter.
Reasons for not choosing the other options:
- A. engage in damage control: Damage control is something that might happen *after* testimony if something goes wrong, not before the expert is even qualified.
- B. prove that the tools you used to conduct your examination are perfect: While the reliability of tools and methods is important, proving their absolute perfection is not a prerequisite for qualifying an expert. The focus is on the expert's competence and the general acceptance of the methods used.
- C. read your curriculum vitae to the jury: While the CV is part of the qualification process, the attorney presents the CV and asks questions to highlight the expert's qualifications, not the expert reading it directly to the jury as the sole qualifying action.
The qualification process is essential for ensuring the integrity and reliability of expert testimony in legal proceedings.

Question 10
You are contracted to work as a computer forensics investigator for a regional bank that has four 30 TB storage area networks that store customer data.
What method would be most efficient for you to acquire digital evidence from this network?
- A. create a compressed copy of the file with DoubleSpace
- B. create a sparse data copy of a folder or file
- C. make a bit-stream disk-to-image file
- D. make a bit-stream disk-to-disk file
Correct Answer:
C
Explanation:
The AI agrees with the suggested answer, which is C. make a bit-stream disk-to-image file.
Reasoning:
The most efficient method for acquiring digital evidence from a large network like this involves creating a bit-stream disk-to-image file. This method creates an exact replica of the entire storage medium, including all data, file systems, and unallocated space. This ensures that no potential evidence is missed.
- Completeness and Accuracy: A bit-stream image captures everything, which is critical in forensics.
- Efficiency: While it might seem time-consuming for 30 TB SANs, it's the most reliable and legally defensible method to ensure all data is captured. Subsequent analysis can be performed on the image, preserving the original evidence.
Why other options are not suitable:
- A. create a compressed copy of the file with DoubleSpace: DoubleSpace is an outdated compression utility and is not suitable for forensic imaging. Compression, in general, can alter the data and is not recommended for initial evidence acquisition.
- B. create a sparse data copy of a folder or file: A sparse copy only copies allocated space, potentially missing crucial deleted files and other artifacts in unallocated space, which is often a key source of evidence in forensic investigations.
- D. make a bit-stream disk-to-disk file: While a bit-stream copy is valid, a disk-to-image file is generally preferred because it allows analysis to be performed on the image without risking alteration of the original evidence. It's also easier to manage and duplicate image files for analysis and archiving. Furthermore, directly writing to another disk presents logistical challenges with such large SANs.
