D.

You need to update the domain’s administration server files.

Question 2

Which three statements are true about the Change Center in the Administration Console? (Choose three.)

Options:

A.

The Change Center has a link to view any servers that need to be restarted

B.

In a Development Mode domain, the configuration lock can be acquired automatically

C.

D.

Locking the console prevents other privileged users from taking the lock until you release it or activate your changes

E.

After activating the changes to a server’s configuration, you must always restart that server

F.

The Change Center is available only in a Production Mode domain

Question 3

Your domain consists of 30 servers. You are using the Administration Console.

Which is the quickest way to identify the servers that are in a Failed health state?

Options:

A.

Use the Filter button from the domain’s Monitoring > Health tab.

B.

Use the Monitoring > Health tab for each server in the domain.

C.

Write a custom WLST script to print out failed server.

D.

Capture a diagnostic snapshot.

Question 4

As part of troubleshooting an application, you need to analyze the HTTP session count and the server heap size over the past six hours. You are using the Administration Console. You want to view both metrics together and correlate their values.

Which three steps should you take in the Administration Console? (Choose three.)

Options:

A.

Create a custom view.

B.

Start the JVM Runtime view.

C.

Drag each metric onto two charts in the same view.

D.

Access the Monitoring Dashboard.

E.

Click the application’s Monitoring tab.

Question 5

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.

Question 6

You are troubleshooting why transactions are not being committed. After investigation, you realize that these transactions have enough time during the first phase of the two-phase commit, but not enough time during the second phase. Therefore, rather than committing, they are timing out and are being rolled back.

Which Java Transaction API (JTA) attribute needs a larger value?

Options:

A.

Timeout Seconds

B.

Abandon Timeout Seconds

C.

Before Completion Iteration Limit

D.

Checkpoint Interval Seconds

E.

Unregister Resource Grace Period

Question 7

You plan to install WebLogic Server by using the generic JAR installer in silent mode.

What are two ways to create the required response file? (Choose two.)

Options:

A.

First install or deinstall graphically. There is an option to save a response file.

B.

Use the sample response file in the installation documentation as a template.

C.

First run the Repository Creation Utility. There is an option to save a response file.

D.

The response file is not required. You can answer questions interactively at the command line.

E.

The genetic JAR installer does not have a silent mode, so you do not need a response file when using this installer.

Question 8

The startup of a WebLogic Server instance fails with the error message:

java.net.BindException : Address already in use

Which two methods help identify what is currently listening at the port and the IP this server is configured to be bound to? (Choose two.)

Options:

A.

The pmap command lists all processes running with their associated port number.

B.

The UNIX lsof command can report information on the process that is listening at a particular IP and port on the local machine.

C.

netstat, which is available on Windows and Linux/UNIX, can report on the process bound to this IP and port.

D.

pstat will report detailed runtime statistics on any process currently listening at this IP and port.

E.

The Linux port watching tool PortInfo can raise an alert anytime a process attempts, succeeds, or fails to connect to a specific IP and port. It can also be used to identify if a port is being used by a java process.

Question 9

Before you view JVM performance information in the administration console, you want to request that the JVM do a garbage collection.

How can you do this in the admin console?

Options:

A.

You cannot do this from the admin console. You must use WLST or a JVM command- line tool.

B.

In the Monitoring > Performance tab, click Dump Thread Stacks.

C.

In the Monitoring > Threads tab, click Dump Thread Stacks.

D.

In the Monitoring > Performance tab, click Garbage Collect.
