B.

C.
On at least two storage servers in the first rack

D.
On all database servers in thefirstrack

E.
On only one database server in second rack

F.

Explanation:
Note:
*The Enterprise Manager agent must be deployed to all compute nodes of the Database Machine.
*Oracle’s documentation uses the term compute node when referring to the database server tier of
the platform.
*The Exadata Database Machine runs Oracle Database 11g Real Application Cluster. The cluster
and the database run on the servers known as database nodes or compute nodes (or simply
“nodes”).
*Cells and compute nodes are not shared between partitions.
*Compute nodes in same partition share the same Cluster.
