1. Scenario : A single tier WebLogic cluster is configured with six Managed Servers. An Enterprise application is deployed to the cluster with a web application and EJBs packaged in the same EAR file.An EAR file is being deployed to the cluster using two-phase deployment. Which of the following is true if one of the Managed Servers is NOT started in the cluster?
A. First and second phase deployment will be completed on all remaining instances in the cluster.
B. First phase deployment will not be completed on the remaining instances in the cluster.
C. First phase deployment will be completed but the second phase will not be completed on the remaining instances in the cluster.
D. First and second phase deployment will not be completed if enforceClusterConstraints is set to true for the Deployer.
E. Both a and d
Answer: E
2. Which of the following statements are true for built-in roles in the WebLogic Server Administration console? Choose two.
A. Users who belong to the Operator role can deploy the applications.
B. Users who belong to the Monitor role can view the server configuration, except for the encrypted attributes.
C. Users who belong to the Admin role cannot deploy applications.
D. Only users who belong to the Admin role can start, stop, and resume the server.
E. Users who belong to the Admin role can modify the entire server configuration.
Answer: BE
3. Scenario : Consider an upgrade requirement from pre-WebLogic Server 10.x to the WebLogic Server 10.x. Since the administration scripts in the prior version used WebLogic Ant tasks for creation and deployment, the team decides to use the Ant build.xml approach and extend this to the current version of the server.
Which of the following about the Ant task wlserver is INCORRECT?
A. wlserver can be used to start, reboot or shut down server instances.
B. wlserver can be used to connect to existing server instances.
C. wlserver can be used to create a multiple server domain configuration.
D. wlserver can be used to create a single server domain and to connect to the server.
Answer: C

Scenario : You have made the decision to migrate all your operations onto WebLogic Server. An application has been chosen from each department for the initial phase of migration ?one from each of Sales, Marketing, Accounts, and Customer Service. The applications will be deployed as individual EAR files to a cluster of WebLogic Server 10.x instances, each with a pool of connections to an Oracle 10g
database that provides corporate and departmental data services. The database team hopes to upgrade the database to use Oracle RAC (Real Application Clusters) shortly, which will require you to configure multiple sets of connections. Connectivity to the existing Service Engineer Dispatch system is via a JMS message bridge. When a service engineer calls in with a report, a message is sent via JMS to the Customer Service application deployed in WebLogic Server. The customer record in the Customer Service database must be updated with details from the message. It is important that the message is not lost because the call management system is not able to resend messages. To address this, the Customer Service application is accessing a persistent JMS Queue using an XA compatible connection factory.
The database security team insists that any use of the corporate Oracle database can be traced to the individual user that made the request. How can this be achieved when using WebLogic JDBC Data Sources?
A. Set the Enable Credential Mapping property for the Data Source.
B. Set Initial Capacity to zero, so each user creates a new connection.
C. Set the value of user to {WLS_USER} in the Properties field.
D. This can only be done using application code.
E. This cannot be done because Data Sources connect using a single username.
Answer: A
5. In a multi-server WebLogic domain, monitoring the JVM statistics showed frequent full garbage collections (gc) on one of the server instances. Which one of the following would greatly reduce the frequency of full gcs?
A. Increasing the young object space in the heap
B. Turning the -verbosegc flag on
C. Adding more servers to the domain
D. Running more servers per machine
Answer: A
