They have no more drives to increase LUN capacity.
How can the customer increase available capacity to the archive server?

• A.Delete old files
• B.Add oversubscribed capacity to the existing LUN
• C.Back up the files, reconfigure the LUN, and restore the data
• D.Compress the data on the LUN

Your customer has an application on VNX File storage. The customer allocated the storage using Manual Volume Management in order to achieve the best performance.

Why was all of the storage used when the file system was created?

• A.The customer did not change the default_slice_flag to "yes" when creating the file pool
• B.The file pool is_dynamic flag is set to "yes" and has taken up all of the LUN space
• C.The stripe_size flag was set to "yes" but no value was entered when the file system was created
• D.Additional LUNs have been used to create the file system because is_greedy is set to "yes"
