Your organization is using a Multi data source (MDS) on WebLogic Server to support applications connecting to an Oracle RAC database. You have been tasked with configuring a new callback handler for the MDS.
Which two statements are true concerning related MDS options and behavior? (Choose two.)
Callback handlers are optional when using the Failover MDS Algorithm because the algorithm can function without them by using predefined criteria for failover and failback. Callback handlers are called for both failover and failback decisions to determine when and how to switch between data sources and to handle any specific conditions that may be required during these events.
You are managing and monitoring durable subscribers for your JMS topics to ensure that all the subscribers would receive persistent messages.
However, JMS connections are currently restricted, so only one connection with the same client ID could exist in the scope of your cluster.
On which page of the Administration Console can you set Client ID Policy to unrestricted in order to lift this restriction? (Choose the best answer.)
To adjust the Client ID Policy, thereby lifting the restriction on JMS connections with the same client ID, you need to navigate to the 'Connection Factory > Configuration > Client' page in the Administration Console. This page allows you to configure connection factories, including setting the Client ID Policy to unrestricted.

What is the correct path within the configuration hierarchy to the MBean that contains the log rotation parameters for server04? (Choose the best answer.)
The correct path within the configuration hierarchy to the MBean that contains the log rotation parameters for server04 is "/Servers/server04/Log/server04". In WebLogic Server, MBeans follow a hierarchical structure under the /Servers node for individual server configurations. This structure indicates that "server04" is an individual server and its log configuration settings would be located within its own Log sub-node. Therefore, the log rotation parameters for server04 can be found at /Servers/server04/Log/server04.
Which two automatic migration scenarios require node manager for all migratable services? (Choose two.)
Node Manager is required for all migratable services in scenarios involving consensus leasing and database leasing with pre and post migration scripts. In consensus leasing, Node Manager coordinates the health and status of all managed servers within the cluster. Similarly, for database leasing with pre and post migration scripts, Node Manager ensures these scripts are executed correctly across managed servers in the cluster. Database leasing without pre and post migration scripts does not necessitate Node Manager as there is no additional script execution required during migration. Synchronous leasing is not related to the automatic migration scenarios that require Node Manager.
You are trying to set up a JMS Session with a specified acknowledgment mode. You want the application that receives the message to explicitly take care of the acknowledgment.
Which option represents a valid choice for the acknowledgment mechanism that you can use? (Choose the best answer.)
CLIENT_ACKNOWLEDGE is the correct acknowledgment mode when setting up a JMS Session where the application explicitly takes care of the acknowledgment. In this mode, the application calls an acknowledge method on a received message. Once this method is called, the session acknowledges all messages received since the last acknowledgment.
