Question #111
Which of the following filesystems would a Linux computer MOST likely use?
- A . HFS
- B . NTFS
- C . FAT32
- D . ext4
Correct Answer: D
D
Explanation:
ext4 is a type of filesystem that is commonly used by Linux operating systems. A filesystem is a method of organizing and storing data on a storage device such as a hard disk drive or a solid state drive. A filesystem determines how data is divided into files and folders, how much space is allocated for each file or folder, how data is accessed and modified, and how data is protected from errors or corruption. ext4 is an improved version of ext3, which was the default filesystem for many Linux distributions until ext4 was introduced. ext4 offers better performance, reliability, and scalability than ext3. HFS, NTFS, and FAT32 are not filesystems that would be most likely used by a Linux computer. HFS is a filesystem that was used by older versions of Mac OS X operating systems. NTFS is a filesystem that is used by Windows operating systems. FAT32 is a filesystem that is used by older versions of Windows operating systems or removable storage devices such as USB flash drives.

Question #112
A technician reading workstation security logs notices that an unidentified device is plugged into a USB port several hours a day but is never plugged in when the technician goes to check the machine. File audits reveal nothing unexpected.
Which of the following devices is most likely causing this message?
- A . Mobile phone
- B . Mouse
- C . Scanner
- D . External hard drive
Correct Answer: A
A
Explanation:
A mobile phone is the most likely device that is causing this message, because it can be plugged into a USB port for charging or data transfer, and then unplugged when the user leaves the workstation. A mobile phone may also not be detected by the file audits, as it may not have any files stored on the workstation or may use encryption or password protection. A mouse, a scanner, and an external hard drive are less likely to be plugged and unplugged frequently, and they would also leave traces of their presence in the file audits or device manager.
