FC0-U51 pdf QUESTION 2
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 9.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 team informs you that they have now implemented Oracle Real Application Clusters (RA for the Customer Service database, and applications should connect to a second database node if the primary node is unavailable. You set up a Multi Data Source in Failover mode, which is configured to use two Data Sources PrimaryDS and SecondaryDS, each connecting to one Oracle RAC node. WebLogic Server will fail over to SecondaryDS if a connection test to PrimaryDS fails. Under what other condition will this happen by default (that is, with no additional options checke)? Exhibit:
A. If a connection to PrimaryDS is not released within Statement Timeout seconds.
B. If all the connections to PrimaryDS are in use.
C. If the administrator has suspended the PrimaryDS Data Source.
D. Failover will only occur if a connection test fails for a PrimaryDS connection.
Correct Answer: C

D. Use the Administration Console to add individual tuning property values to the deployment plan or to validate a custom deployment plan.

FC0-U51 pdf QUESTION 6
Which of the following is false regarding auto-deployment?
A. If auto-deployment is enabled, when an application is copied into the /autodeploy directory of the Administration Server, the Administration Server detects the presence of the new application and deploys it automatically.
B. If you delete application files from the /autodeploy directory when the server is not active, WebLogic Server will still detect that the application files were deleted even when the server is again in an active state.
C. When you switch from the development mode to production mode, any applications that were previously deployed via the /autodeploy directory remain deployed; if you wish to undeploy or redeploy such applications after you have switched to production mode, you must undeploy or redeploy them manually.
D. When an application has been auto-deployed in the exploded archive format, the Administration Server periodically looks for a file named REDEPLOY in the exploded application directory. If the timestamp on this file changes, the Administration Server redeploys the exploded directory.
E. Production mode disables the auto-deployment feature and prevents any applications you place in the / autodeploy directory after you switch to production mode from being deployed.
Correct Answer: B
