You create a new Managed Server in your domain by using the administration console. You give it the listen address of 192.0.2.0 and the listen port of 7100.You save and activate the changes.
You use the domain start script to start the new server. It fails. One of the messages in the window in which you can ran the script is:
Server failed to bind to any usable port.
You investigate and see that another process is running on 192.0.2.0 on port 7100.You also find many unused ports at that IP address.
Which two statements are true? (Choose two.)

  • A. It is not an instance of WebLogic Server from this domain running at 192.0.2.0:7100. The administration console does not allow you to create a server at the same listen address and port as one already configured in the domain.
  • B. It is an instance of WebLogic Server running at 192.0.2.0:7100. Other processes do not interfere with WebLogic Server.
  • C. Changes the port number to an unused one to resolve this issue.
  • D. It cannot be the administration server running at 192.0.2.0:7100, because admin servers run on port 7001.
  • E. Because this Managed Server has never been started, it does not have a local copy of the configuration. If it did, by using Managed Server Independence, it would be able to switch to an unused port of its configured port was busy.
