Identify them.

While creating a new domain in the Configuration Wizard, there are two types of machines that
may be configured. Identify them.

A.
Machine and Windows machine

B.
administrator machine and managed machine

C.
machine and Unix machine

D.
stand-alone machine and cluster machine

E.
RDBMS machine and LDAP machine

Explanation:
Administrator machine:
The Choose the Administration Server window prompts you to designate a server as the
Administration Server. This window is displayed automatically only if the selected template
includes multiple servers that are not assigned to clusters.
To choose the Administration Server:The Server Details area displays detailed information about
the selected server. By default, the currently assigned Administration Server is selected.
The Configure the Administration Server and Configure Managed Server(s) windows are updated
to reflect your changes.
Managed machine:
The minimum requirement for your domain is a single Administration Server on a single machine.
In addition, however, you have the option of configuring other resources to be managed by the
Administration Server and distributing them across multiple machines. Specifically, you can:
* Add, change, or delete Managed Servers
* Add, change, or delete clusters
* Group Managed Servers into clusters, or change current groupings
* Assign servers to machines, or change current assignments
Note: The Managed Servers, Clusters, and Machines Options window prompts you to specify
whether you want to distribute your WebLogic configuration across Managed Servers, clusters,
and physical machines
Note 2:
The Configure Managed Serverswindow prompts you to provide the configuration information
for one or more Managed Servers. Production environments typically deploy one or more
Managed Servers, in addition to the Administration Server, to host enterprise applications.
