Q18. You configuring has two half racks, one with high capacity disks and other with high performance disks and high capacity expansion half rack.
There are two RAC clusters, one on each half rack, which have separate storage grids, each consisting of some of the storage servers in the configuration.
You are planning your deployment of Enterprise Manager to monitor all the components of this multi-rack Database Machine, and must provide for high availability of the monitoring infrastructure.

A. Enterprise manager support must be deployed to only one Enterprise Manager Agent in each cluster.
B. A secondary agent must be deployed on a database server in the same cluster as the server hosting the primary agent.
C. Enterprise Manager support must be deployed to all Enterprise Manager Agents in each cluster.
D. A secondary agent may be deployed on a database server in a different cluster than the server hosting the primary agent.
E. A secondary agent must be deployed on a database server in a different cluster than the server hosting the primary agent.
F. Enterprise Manager support must be deployed to at leasttwoEnterprise Manager Agents in each of the two RAC clusters.
Answer: AD
