Question No : 10
You are archiving to a pair of bi-directionally replicating EMC Centeras in Governance
mode, and you are using retention classes to manage retention. You initially set the
retention class "email" to five years, and have been archiving e-mail content for the past
two years. You have recently been informed that you need keep e-mail content for only one
year, so you change the definition of the retention class "email" to one year. You then
delete all content older than one year. During an audit, you discover that the deleted
content is still on the target cluster. What is the most likely reason for this?
A. You cannot change retention on a Governance cluster.
B. Updated retention class has not been exported.
C. The retention class on the target cluster was not updated.
D. The default retention is still five years.
