Question 1

The BIOS is stored in the Encrypting File System (EFS).

Accepted Answer

The BIOS is not stored in the Encrypting File System (EFS), it is stored on a chip on the motherboard.

Question 2

File systems allow end-users to perceive their document as multiple streams of bytes while providing for its storage in contiguous sectors.

Accepted Answer

File systems allow end-users to perceive their documents as multiple files or directories, not multiple streams of bytes. Additionally, file systems can store a file in non-contiguous sectors through the use of fragmentation.

Question 3

Which of the following tools are the most popular and stand-alone imaging utilities employed for forensic investigators?

Accepted Answer

ByteBack and Safeback are the most popular and stand-alone imaging utilities employed for forensic investigators. EnCase is a digital forensic software toolkit that also includes imaging capabilities, but it is not a stand-alone imaging utility. DECLASFY and BRANDIT are not imaging utilities. Data Dumper and Grep are command-line tools for data manipulation and searching, but they are not imaging utilities.

Question 4

Extraction of a file pertinent to an examination may be based on the file name and extension, file header, file content, and location on the drive.

Accepted Answer

These are all valid methods for identifying and extracting a file for examination purposes.

Question 5

Which of the following programs extends decryption capabilities beyond a single computer by using the distributed power of multiple computers across a network to decrypt files and recover passwords?

Accepted Answer

The program that extends decryption capabilities beyond a single computer by using the distributed power of multiple computers across a network to decrypt files and recover passwords is Distributed Network Attack. The other options do not have this capability.

Question 6

Forensic imaging programs must be capable of making a bitstream duplicate or an image of an original disk or partition onto fixed or removable media.

Accepted Answer

Forensic imaging programs must be able to create a bitstream duplicate or an image of the original disk or partition. This is necessary for preserving the integrity of the original evidence and for conducting analysis on the duplicate without modifying the original data. The image is typically saved onto fixed or removable media for storage and analysis purposes.

Question 7

The physical extraction phase identifies and recovers files and data based on the installed operating system, file system, and/or application.

Accepted Answer

The physical extraction phase involves copying the entire contents of a storage device at the bit level, without regard to the installed operating system, file system, or applications.

Question 8

The logical file size refers to the exact size of a file in bytes.

Accepted Answer

The logical file size is the actual size of a file measured in bytes. It is not an approximation or estimation but rather an exact value.

Question 9

Many agencies do not avail themselves of the free training courses provided by the FBI and the Federal Law Enforcement Training Center as the agencies are unable to afford the loss of personnel.

Accepted Answer

Many agencies are unable to afford the loss of personnel to attend the free training courses provided by the FBI and the Federal Law Enforcement Training Center, leading them to not take advantage of the training.

Question 10

The cluster size for a particular device is specified in which of the following?

Accepted Answer

The cluster size for a device is specified in the BIOS Parameter Block (BPB), which is part of the file system metadata and provides essential information about the file system, such as the number of bytes per sector, sectors per cluster, and the total number of sectors on the volume.

Question 11

The statement of compliance or noncompliance with certain specifications or other requirements must be included in a report.

Accepted Answer

Including a statement of compliance or noncompliance with certain specifications or other requirements is necessary for the completeness and accuracy of a report. This helps ensure that the report is useful and reliable for its intended purpose.

Question 12

A file system is the combination of a hardware device and computer instructions and data that reside as read-only software on that device.

Accepted Answer

A file system is a method of organizing and storing files and directories on a computer's hard drive or other storage devices. It includes both hardware and software components, but the computer instructions and data that reside on the device are not read-only and can be modified or updated by the operating system or user.

Question 13

The smallest forms of data storage are represented by binary digits.

Accepted Answer

Binary digits (or bits) are the smallest unit of data storage, represented by 1s and 0s.

Question 14

Overt files are not hidden, deleted, or encrypted.

Accepted Answer

Overt files are files that are not hidden, deleted, or encrypted. They are easily visible and accessible to anyone with access to the machine or storage device.

Question 15

Raw image files increase the costs associated with the maintenance of forensic laboratories and software libraries because they exhibit backward compatibility issues.

Accepted Answer

Raw image files are generally considered to be more compatible across different forensic software tools and versions, reducing issues related to backward compatibility. They are a fundamental format used for digital evidence preservation.

Question 16

Electronic data recovery should be reserved for instances when the instrumentality of computer technology has been demonstrated.

Accepted Answer

Electronic data recovery can be necessary in various situations, not only when the instrumentality of computer technology has been demonstrated. It can be used for recovering lost, deleted, or corrupted data from any digital device, not just when there's a proven failure or issue with the computer technology itself.

Question 17

Most contemporary integrated packages have stand-alone imaging programs.

Accepted Answer

Most contemporary integrated packages include imaging capabilities within the suite rather than as stand-alone programs, offering seamless integration with other tools.

Question 18

During analysis of digital evidence, which of the following elements is addressed?

Accepted Answer

The answer of During analysis of digital evidence, which of...

Question 19

A file system is the disk management platform employed by a particular operating system.

Accepted Answer

A file system is indeed the disk management platform employed by a particular operating system, which dictates how data is stored, accessed, and organized on a storage device such as a hard drive or SSD. Each operating system typically has its own unique file system, such as NTFS for Windows, HFS+ for macOS, and ext4 for Linux.

Question 20

Which of the following terms refers to a suspect's guilty mind or intent, as might be demonstrated by the use of data hiding or drive wiping techniques?

Accepted Answer

Mens rea refers to a suspect's guilty mind or intent, which can be inferred by their use of techniques like data hiding and drive wiping to conceal evidence of a crime. Harm refers to the negative consequences or damage caused by the crime. Actus reus refers to the criminal act itself, while ownership is not directly related to the concept of mens rea or criminal intent.
