Which two are true regarding the configuration used to support this?

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.
If the host running the agent which has database machine targets bound to it fails, the monitoring
of these targets must be another agent.
Which two are true regarding the configuration used to support this?

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.

Explanation:
Note:
*Instructions for configuring a high availability solution for the Exadata Storage cell orany other
Exadata plug-in are documented in the Oracle Database Machine Monitoring Best Practices (Doc
ID 1110675.1) document located in My Oracle Support
*High Availability for Plug-Ins
Normally a plug-in target is bound to a specific agent
If the agent is down the target cannot be monitored
A procedure exists to facilitate target failover to a secondary agent
*The Enterprise Manager agent must be deployed to all compute nodes of the Exadata Database
Machine.
*The Oracle ILOM plug-in monitors the Oracle ILOM service processor in a
compute node for hardware events and records sensor data to the Oracle
Enterprise Manager Repository.
The ILOM plug-in is deployed to the Enterprise Manager (EM) Agent on the first
compute node in an Oracle Database Machine, and only that EM agent
communicates with the EM Management Server and Repository for all ILOM
database server service processors in the Oracle Database Machine.
*OEM Agent and Exadata Plug-ins
1. OEM Agent and Plug-Ins
are deployed under Oracle
Home
2. Agent incorporates
additional functionality in
Plug-In
3. Agent and Plug-in
DB Server on Exadata DBM
3. Agent and Plug-in
communicates with
Storage Server
4. Plug-Ins are available for
monitoring all Exadata
hardware components
5. OEM Agent communicates

with the OEM
