The Administration Server of a domain fails due to a hardware failure. The hardware is beyond repair.

Before the failure you prepared a “backup admin server”. You go through your planned recovery process and are successful. The Administration Server is now running on different hardware. The managed servers of the domain automatically reconnect to the admin server.

Select the two statements that are true. (Choose two.)

Options:

A.

Files of deployed applications are available to the backup admin server from the same relative location as they were to the original admin server.

B.

At the time of the failure, the backup admin server was running in “Standby” mode on different hardware in the same network.

C.

When the admin server failed, you must have shut down and restarted the managed servers, otherwise they could not have reconnected to the failed admin server.

D.

The backup admin server is any one of the running managed servers. You select one of the managed servers, stop it, set its “administration” flag, and restart it as the admin server of the domain.

Questions 11

Consider a multiple node domain. On the administration server’s node, you edit setDomainEnv.sh in the bin directory and add a new JAR file to the CLASSPATH. You stop and restart all three WebLogic Server in the domain. Upon investigation, you discover that only applications deployed to one WebLogic Server are able to access the JAR file code. How do you explain this?

Options:

A.

You must also set the domain attribute “CLASSPATH Discovery Enabled.”

B.

Each machine that hosts WebLogic Servers has its own domain directories. The script must be modified there as well.

C.

Only the first server to receive the new configuration from the administration server gets the updated CLASSPATH

D.

The CLASSPATH is not for application code. It is for interval WebLogic Server code. So, only applications deployed to the administrative server can access code through the CLASSPATH

Questions 17

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.)

Options:

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.

F.

The port number can stay 7100 if this machine has another IP address and the port is unused at that address.
