A current production WebLogic Server (WLS) domain needs to be upgraded without affecting the users. What are the five steps to follow for a Rolling Update? (Choose five.)
A. Back up the contents of your domain.
B. Use pack and unpack to upgrade each of the servers in the machine.
C. Shut down the servers in a single machine.
D. Repeat the process for all machines in the domain.
E. Restart the servers in the machine.
F. Repeat the process for all domains in the machine.
G. Upgrade the servers in the machine.
Poor ventilation and cooling in and around the machine that hosts your administration server and a clustered managed server causes a local hard drive failure and thus both servers crash as well.
This is the first time this crash has occurred in production but an automatic Whole Server Migration kicks in as expected. The clustered server migrates to a machine on which it has never run before, and for that reason the server cannot be started on this new machine.
Which action could have helped to launch this migrated clustered server? (Choose the best answer.)
A. Shut down and relaunch the Node Manager.
B. Ensure that the Administration Server is up when the server migration is being performed.
C. First restart the Administration Server, remove this managed server from the cluster, restart it manually, and then target it back to the cluster.
D. Use a shared disk/NFS for all the migratable servers in the cluster.
E. Copy the Node Manager security files to the new machine that hosts your migrated server.
For some reason, servers in your domain are failing. The host machines are pingable and the WebLogic JVM processes are running but the getState() method on the ServerRuntimeMBean reports FAILED.
In the future, when this happens, you want these failed servers to be shut down and then restarted automatically without human intervention. At the same time, you want to constrain how much time will be spent restarting those servers and how many restart attempts will be made.
Pick the two options that would help with this situation. (Choose two.)
A. For each server (or cluster), set RestartInterval to an appropriate positive integer.
B. When starting Node Manager, use the WLST nmStart command and pass in a WLST properties object with RestartMax set to an appropriate positive integer.
C. Start the servers by executing the restartManagedWebLogic.sh script in the domain's /bin directory.
D. Make sure all managed servers are members of a cluster with ReplicationGroupsEnabled set to true.
Which three considerations do you need to keep in mind while configuring a JMS file store in order to ensure the highest possible performance? (Choose three.)
A. Privilege local disks over remotely mounted disks.
B. Compress the file store when there are no more messages.
C. Select the cache-flush synchronous write policy.
D. Dedicate one disk for all file stores.
E. Set MessagesMaximum in your JMS destinations.
Your architecture requires that you create 100 JMS Queues with similar, though not necessarily identical, configuration settings.
Which entity will help you carry out the task efficiently? (Choose the best answer.)
A. JMS Distributed Destination
B. JMS Foreign Server
C. JMS Template
D. JMS Destination Key
Review the image below. It depicts the architecture for the WebLogic Server auditing.
Where in the architecture does WebLogic apply audit configuration parameters that determine if an audit message is logged? (Choose the best answer.)
A. Authorization provider
B. Authentication provider
C. Auditor service
D. Audit provider
You have an enterprise application that includes a resource adapter module. You are considering leveraging WebLogic Server's Production Redeployment feature for this application. In preparation for deployment, you decide to create a checklist of items to discuss with the developers of the application.
Which item would you omit from your checklist as it is irrelevant to production Redeployment? (Choose the best answer.)
A. Ensure the developers have implemented the weblogic.connector.extensions.Suspendadle interface for the adapter.
B. Ensure that the adapter is accessed by a web or web service module within the application.
C. Ensure the adapter is used in an application-scoped manner, having enable-access-outside-app set to false.
D. Ensure that the adapter is compliant with the JCA 1.5 specification.
You need to log the JMSMessageID header value for incoming messages.
What is the prefix that you would see for the header values? (Choose the best answer.)
A. VAL:
B. JMS:
C. ID:
D. NO:
E. MSG:
Which two statements correctly describe the WLST nmGenBootStartupProps command? (Choose two.)
A. The target root directory must be on the same machine on which Node Manager is running.
B. The target root directory must be on the same machine on which the Administration Server is running.
C. The name of a server must be supplied to the nmGenBootStartupProps command; otherwise, the command will fail.
D. If you do not specify a server name using the servername argument, the argument defaults to myServer, which must match a server name in the domain or the command will fail.
E. The nmGenBootStartupProps command generates the Node Manager properties files, boot.properties and startup.properties, for the specified server.
Your application includes a message driven bean (MDB) that is listening to messages on a JMS Queue. You need to ensure that every message is processed exactly once by the MDB.
Which configuration allows you to achieve this requirement? (Choose the best answer.)
A. Add an exception handler for the onMessage method in the MDB.
B. Set the Redelivery Limit for the Queue to zero.
C. Use container-managed transactions, so that messages are redelivered if unacknowledged.
D. Set the MDB instance count to 1 in the deployment descriptor.
