Users complain that it takes several seconds to get the result for DQL queries on dm_document
searching for keywords. Your database administrator says that the disk I/O rate on the database
machine is consistently high and no other change can be made to the database hardware. The
database and Content Server run on separate hosts.
How could you solve this problem on the Content Server?

A.
add more or faster CPUs on the Content Server machine

B.
create a selective database index against the dmr_content_s table

C.
create a database index on the keywords column of the dm_sysobject_r table

D.
buy faster disks for storing the Documentum content
