Explanation:

the storage of management information and the automation of management activities for all
entities managed in the network. It also includes facilities for serving the web-based user interface,
which is the Cloud Control console.
B:The Management Agent is the lightweight process that acts as a proxy for Enterprise Manager
on the various hosts in the network where entities that Enterprise Manager manages are located.
It communicates with the OMS to collect and deliver monitoring information and to coordinate
management activities executed against the management entities.
E:The Management Repository is the Oracle Database that stores all important management
information for the entities managed by Enterprise Manager. The Oracle Management Service
(OMS) uses the Management Repository to store and retrieve key information, such as monitoring
