These attribute parameters can only be configured when the WORM root directory is set. Only then the user's view can not be modified.
C. To prevent changes in the directory or file protection time because of the changes in cluster time, a directory or file is configured with WORM attributes. After the directory or file will use the WORM clock to time, set the WORM clock. When the system will be based on the clock, user's file will not be modified over the protection period.
D. If the cluster time is earlier than the WORM clock, the WORM clock will be chased every hour for up to 138 seconds to adjust. If the cluster is after the WORM clock, the WORM clock adjusts to the cluster time.
正解：A
