Question 1

Which three statements correctly describe a relationship between Node Manager and Administration Server? (Choose three.)

A. An Administration Server can be under Node Manager control: You can start it, monitor it, and restart it using Node Manager.
B. An Administration Server can be a Node Manager client: When you start or stop Managed Servers from the Administration Console, you are accessing Node Manager using the Administration Server.
C. An Administration Server supports the process of starting up a Managed Server with Node Manager: When you start a Managed Server with Node Manager, the Managed Server contacts the Administration Server to obtain outstanding configuration updates.
D. By default, the Administration Server starts a Node Manager with the startNM script in the domain’s bin folder.
E. By default, the Administration Server starts a Node Manager with the startNodeManager script in the domain’s config folder.
F. Node Manager requires an Administration Server to be running before it can start any Managed Servers.
G. A Node Manager can be a client of an Administration Server – When Node Manager needs to monitor Managed Servers, it uses the Administration Server’s runtime MBeans.

Correct Answer:BEF
B: If you run Node Manager on a machine that hosts Managed Servers, you can start and stop the Managed Servers remotely using the Administration Console or from the
command line.
E: Although running Node Manager as an operating system service is recommended, you can also start Node Manager manually at the command prompt or with a script. Use startNodeManager.cmd on Windows systems and startNodeManager.sh on UNIX systems.
F: Requests from the Administration Console (or JMX utilities such as weblogic.Admin) to start a Managed Server using Node Manager are issued to the Administration Server for the domain that contains the Managed Server. The Administration Server dispatches the start command to the Node Manager process on the machine that hosts the target Managed Server. Node Manager executes the start command and creates a Managed Server process.

Question 2

Your domain is experiencing some intermittent problems that you are not able to figure out on your own. You have opened a case with Oracle Support to help you figure out the problem. The support engineer would like to use the WebLogic Diagnostic Framework (WLDF) to obtain an overall view of your WebLogic Server environment to try to narrow the problem to a particular subsystem.
What WLDF data does the support engineer request from you? (Choose the best answer.)

A. Diagnostic image snapshot
B. Java Flight Recording of the JVM
C. Instrumentation log
D. Specific harvested metrics

Correct Answer:A
Diagnostic Image Capture gathers the most common sources of the key server state used in diagnosing problems. It packages that state into a single artifact, the Diagnostic Image.

Question 3

You have a versioned application deployed in your production environment. You have been asked to troubleshoot why
the most recent production redeployment appeared to allow the older version to retire too quickly.
In this case, the application had active RMI clients, but their subsequent calls were directed to the newer version immediately rather than waiting for the expected five minutes defined by the retirement timeout argument. The script command was:
java weblogic.Deployer –adminurl http://localhost:7001 –user weblogic
-password Welcome1 –redeploy –name myDeployment
-source /myDeployments/myApplication/appX
-retiretimeout 300
You expected the older version to remain active (when there are active RMI clients) for five minutes after executing the production redeployment.
Which modification should have been made to this command to ensure the older version remains active? (Choose the best answer.)

A. java weblogic.Deployer –adminurl http://localhost:7001 –user weblogic-password Welcome1 –redeploy –name myDeployment-source /myDeployments/myApplication/appX-retiretimeout 300 –rmigraceperiod 300
B. java weblogic.Deployer –adminurl http://localhost:7001 –user weblogic-password Welcome1 –redeploy –name myDeployment-source /myDeployments/myApplication/appX-retiretimeout 300 -keepsessions
C. java weblogic.Deployer –adminurl http://localhost:7001 –user weblogic-password Welcome1 –redeploy –name myDeployment-source /myDeployments/myApplication/appX-retiretimeout 300 –timeout 300
D. java weblogic.Deployer –adminurl http://localhost:7001 –user weblogic-password Welcome1 –redeploy –name myDeployment-source /myDeployments/myApplication/appX-retiretimeout 300 –remote

Correct Answer:D
The –remote argument indicates that weblogic.Deployer is not running on the same machine as the Administration Server, and that source paths specified in the command are valid for the Administration Server machine itself. If you do not use the -remote option, weblogic.Deployer assumes that all source paths are valid paths on the local machine.

Question 4

You are tasked with doing a rolling upgrade of a production domain that will minimize user interruptions. What are two characteristics of a rolling upgrade? (Choose two.)

A. Configuration changes can be made during the Rolling Update process.
B. A major upgrade, for example 11g to 12c, can be accomplished with a Rolling Update.
C. The machines can be upgraded in any order.
D. The machine hosting the Administration Server must be upgraded first.
E. Avoid configuration changes until all the servers in the domain have been upgrade

Correct Answer:DE
D: The rolling upgrade process includes stopping the Administration Server, installing the upgrade, restarting the Administration Server, and then doing the same for each Managed Server in the cluster.
E: You should not make configuration changes during the upgrade process until all the servers in the cluster have been upgraded. This is especially true for new configuration options.
Note: Rolling Upgrade is the process of upgrading a running WebLogic Server cluster with a patch, maintenance pack, or minor release without shutting down the entire cluster or domain. During the rolling upgrade of a cluster, each server in the cluster is individually upgraded and restarted while the other servers in the cluster continue to host your application.

Question 5

You are planning to use WebLogic JMS for implementing my enterprise messaging architecture. Which messaging paradigm is invalid in this context? (Choose the best answer.)

A. Point to Point messaging
B. Publish Subscribe messaging
C. Datagram messaging
D. Persistent messaging

Correct Answer:C
