What is the reason for the failure?

An administrator has retained snapshots for a single MTree and is trying to create a new one. An error message is received.

What is the reason for the failure?
A . The maximum number of snapshots has been exceeded
B . The DDOS needs to be upgraded
C . The user does not have the permission to retain more snapshots
D . There are not enough snapshot licenses

Answer: A

Explanation:

The maximum number of snapshots allowed per MTree is 750. Warnings are sent when the number of snapshots per MTree reaches 90% of the maximum allowed number (from 675 to 749 snapshots), and an alert is generated when the maximum number is reached. To clear the warning, expire snapshots and then run the file system cleaning operation.

Note: To identify an MTree that is nearing the maximum number of snapshots, check the Snapshots panel of the MTree page regarding viewing MTree snapshot information.
