Question 7

Which statement is true regarding VFS?

AVFS is a set of ANs designed for BtrFS to provide portability.

BVFS is a high-performance journaling file system format used by default by YaST and parted.

CVFS is an abstraction layer in the kernel that provides the same interface to applications and the user, regardless of which file system format is used.

DVFS is a translation layer to allow applications written for ext2 and ReiserFS to run on ext4 file systems.

EVFS is a translation layer to allow applications to run on mobile platforms.

Answer : C

The statement that is true regarding VFS is that VFS is an abstraction layer in the kernel that provides the same interface to applications and users regardless of which file system format is used. VFS stands for Virtual File System or Virtual File System Switch. It allows different types of file systems (such as ext4, xfs, nfs, etc.) to be accessed through a common set of system calls and functions. VFS also provides caching and buffering mechanisms to improve performance and reliability. Reference: https://documentation.suse.com/sles/15-SP3/html/SLES-all/sec-vfs.html
