Which statement is true?

You installed WebLogic, SOA Suite, and Oracle Service Bus on a machine and want to use the
WebLogic Node Manager to start servers for each product. Which statement is true?

A.
You need to install a separate node manager for each Middleware Home that has a unique and
minor WebLogic Version Number.

B.
You need to install and configure only one instance of Node Manager for all products,
regardless of the WebLogic version number.

C.
You need to install and configure a separate Node Manager for each domain of each product
want to run on the machine.

D.
You need to install one Node Manager but use separate SSL certificates for each product when
securing the network communication to the machine.

Explanation:

Note:
* A Node Manager process is not associated with a specific WebLogic domain but with a
machine. You can use the same Node Manager process to control server instances in
any WebLogic Server domain, as long as the server instances reside on the same
machine as the Node Manager process. Node Manager must run on each computer
that hosts WebLogic Server instances—whether Administration Server or Managed
Server—that you want to control with Node Manager.
* In managing multiple servers, Node Manager uses multiple configuration files and outputs log
files to multiple directories.
* nodemanager.domains
This file contains mappings between the names of domains managed by Node Manager and their
corresponding directories.
* Node Manager in the WebLogic Server Environment
