Question

Which of the following is true about the interplay between virtual memory subsystem (MMU+kernel data structures) and VFS: *

a)MMU (and the kernel) takes care of page replacement policies while ignoring the data blocks represented by VFS structures and thus potentially causes starvation.

b)MMU (and the kernel) translates virtual memory to real memory block which finally points to the data structures represented by VFS (e.g. inodes).

c)MMU (and the kernel) relies on page faults to identify pages to import from the backing store and replace pages back to it (so as to make room for new pages). VFS uses this principle to also import file data blocks from the on disk file system and places them on pages allocated.

d)None of the above

2.Which of the following is true about file system mounting: *

a)None of the above.

b)Devices that do not have file systems can also be mounted to the filesystem, e.g. devices like keyboard and mouse, as every device appears as a file in the filesystems.

c)Only a recognized partition / file system can be mounted at a particular directory.

d)You could mount swap partitions to specific directories.
