5. Which of the following options provides fast file system recovery?
A Ext2
B Sysfs
C Cache
D Logging
D

6. Which command is used to mount the file system as read-only?
A mount –a
B mount –v
C mount –f

C /etc/inittab
D /etc/boot
B
The /etc/fstab configuration file contains the information necessary to automate the process of mounting partitions. In short, mounting is the process by which a raw (physical) partition is prepared for access and assigned to a location on the file system tree (or mount point).

A Inode
B Data blocks
C File blocks
D Directory file

10. Binary or executable files are _____ ?
