Question 1

Which of the following is true about the Mac OS Extended file system?
A) It is a journaling file system.
B) File names are always case insensitive.
C) Volume sizes up to 128 TB are supported.
D) The volume information block is a list of all files on the volume.

Accepted Answer

Mac OS Extended, also known as HFS Plus, includes a journaling feature that helps protect the file system integrity in the event of improper shutdowns or hardware failures.

Question 2

On a Linux system, the inode link count for a file has a value of two. What is true about the file?
A) The file has a size of 2 MB.
B) The file has been copied two times.
C) The file has a hard link.
D) There are two file owners.

Accepted Answer

The inode link count indicates the number of hard links to a file. A count of two means there is one additional hard link to the file besides its original name, not the size, copy count, or number of owners.

Question 3

You have installed a new disk on a macOS system that uses APFS. After rebooting, you open Disk Utility to create a new volume so you right-click on the disk in the left pane. However, you don't see an option to create a new volume. What is the most likely reason for this?
A) You can only create volumes using the command line.
B) You need to create a container in Disk Utility before you can create a volume.
C) APFS doesn't allow new volumes to be created after macOS has been installed.
D) Each disk on a macOS system is also a volume so there is no need to create one.

Accepted Answer

APFS utilizes a container structure, where volumes reside. Before adding a volume, a container must be established or selected in Disk Utility.

Question 4

Where is the root of the Linux folder structure found?
A) the MBR
B) inode 0
C) the MFT
D) the superblock

Accepted Answer

The root of the Linux folder structure is found at inode 0. Inodes are data structures on a filesystem on Linux that store information about files and directories, not the actual data of files but metadata. Inode 0 is traditionally reserved and not used for storing data but is significant in the context of filesystem structure.

Question 5

A Linux system user has configured the document folder structure for her department. She has found that she sometimes needs the same file such as policy and procedure manuals to be located in multiple folders. She also wants to be sure that if the file is modified, the modification is available in all folders. What do you suggest?
A) use the Shadow Copies feature to monitor for changes
B) tell her to manually copy the file at the end of each day
C) write a script to copy the file to all folders periodically
D) use hard links to make the file appear in several folders

Accepted Answer

Hard links allow a single file to appear in multiple locations in the filesystem. Any changes made to the file are reflected across all links, as they all point to the same inode on the disk. This is the most efficient way to meet the requirement of having the same file accessible from multiple folders with all changes being synchronized.
