An IT professional is setting up a new server that will run an open-source operating system. The server needs a robust file system capable of handling large files and large volumes of small files while providing journaling capabilities to maintain data integrity. Which file system should the IT professional consider using?
Ext4 is the correct answer because it is designed for Linux systems and provides large file and volume support, as well as journaling capabilities, which help protect the data against power outages and system crashes by keeping a record of changes not yet committed to the file system. Although NTFS also provides journaling and can support large files, it is primarily used with Windows operating systems. FAT32 is an older file system without journaling capability and it has a maximum file size limit of 4GB, which makes it unsuitable for handling very large files. Ext3 would be a viable alternative but does not support larger volumes and files as efficiently as Ext4.
