220-1102 Question 15
Single answerFourth extended filesystem (ext4)A technician is replacing a failed drive in an Ubuntu workstation used by a graphics team. The original Linux data partition was formatted with ext4. After installing the new drive, the technician needs to create a Linux-native filesystem that supports journaling and is commonly used as the default on many Linux distributions. Which filesystem should the technician choose?
- A
ext4
- B
NTFS
- C
FAT32
- D
exFAT
Show answer and explanation
Correct answer: A
Explanation
The best answer is ext4 because it is the standard Linux-native filesystem in many real-world desktop and server deployments and includes journaling, which helps protect filesystem integrity after crashes or unexpected shutdowns. In an A+ Core 2 context, candidates should recognize ext4 as the common default Linux filesystem, especially when replacing or recreating a Linux partition. NTFS, FAT32, and exFAT may all be encountered by technicians, but they are generally selected for Windows compatibility or removable-media use cases rather than as the default filesystem for a Linux workstation. This aligns with common Linux administration practice and documentation from Linux distributions and filesystem tools that identify ext4 as a standard general-purpose filesystem.
- A. Correct.
Correct. ext4 (Fourth Extended Filesystem) is a Linux-native filesystem that supports journaling and is widely used as the default filesystem on many Linux distributions. In this scenario, choosing ext4 matches the original environment and is appropriate for a Linux workstation.
- B. Incorrect.
Incorrect. NTFS is primarily a Microsoft Windows filesystem. While many Linux distributions can read and write NTFS with proper support, it is not the standard choice for a Linux-native system partition or general Linux data partition when ext4 is the expected filesystem.
- C. Incorrect.
Incorrect. FAT32 is widely compatible across operating systems, but it does not provide journaling and has significant limitations, including a maximum individual file size of 4 GB. It is typically used for removable media rather than a primary Linux workstation filesystem.
- D. Incorrect.
Incorrect. exFAT is useful for cross-platform removable storage and supports larger files than FAT32, but it is not the typical Linux-native journaling filesystem used for internal Linux partitions. It is not the best match for replacing an ext4 partition in a Linux workstation.
