A file system has auto_extend enabled. If the file system size is greater than the extend_size value, what will
happen when the file system reaches its HWM?

A.
The file system is extended by the extend_size value.

B.
The file system is extended by five percent of its size.

C.
The extend_size value cannot be less than the file system size.

D.
The file system will not be extended.

Explanation:
Auto extension causes the file system to automatically extend when it reaches the high water mark and permits
you to grow the file system gradually on an as-needed basis. The file system usage threshold is an integer in
the range of 50-99 percent (the default is 90 percent). With auto-extension enabled and the HWM set at 90
percent, an automatic extension guarantees that the file system usage is at least 3 percent below the HWM.
Calculating the automatic extension size depends on the extend_size value and the current file system size, the
file system I/O rate and polling interval. If the file system usage after the first extension is within three percent of
the HWM, the Control Station extends the file system by an additional amount, bringing file system usage below
three percent of the HWM. If a file system is smaller than the extend_size value, it extends by its size when it
reaches the HWM. If a file system is larger than the extend_size value, it extends by 5 percent of its size or the
extend_size, whichever is larger, when it reaches the HWM.
