keyword “none” in the GUI
Answer: C
QUESTION 3
Management asks you to set quota limits on a directory tree.
They want the default set to 500 MB with a possible overhead of 20%. They want to enforce these
limits on the sum of the logical size of objects in that quota tree. What is part of the correct
answer?
A. Set the hard limit to 600 MB, and set the file size quota policy on the Data Mover.
B. Set the hard limit to 600 MB, and set the file size quota policy on the file system.
C. Set the hard limit to 500 MB, and set the file size quota policy on the file system.

C. Tree quotas on the file system
D. User quotas on the tree
Answer: A
QUESTION 5
Which conditions must be met before tree quotas can be enabled?
A. File system and parent directories must exist, but the parent directory on which the tree quota is
to be applied must already exist.
