The major components of the WebLogic JMS Server architecture, as illustrated in the figure below.
*(A) JMS servers that can host a defined set of modules and any associated persistent storage that reside on a WebLogic Server instance.
*(B) JMS modules contains configuration resources (such as queues, topics, and connections factories) and are defined by XML documents that conform to the weblogic-jmsmd.xsd schema.
*Client JMS applications that either produce messages to destinations or consume messages from destinations.
*(E) WebLogic persistent storage (file store or JDBC-accessible) for storing persistent message data.
The following figure illustrates the WebLogic JMS architecture.

Question 2
Assume that you would like to clone an existing WebLogic Domain and enable some customizations. What scenario would you choose?
Options:
A.
In the Enterprise Manager, find the domain to be cloned. Choose "Clone WebLogic Domain" from the context menu. In the graphical wizard, customize and extend the domain if needed. These steps will only clone only the domain configuration. Binaries with deployments are needed to be cloned by operation on the file system.
B.
In the Enterprise Manager, find the domain to be cloned. Choose "Clone WebLogic Domain" from the context menu. In the graphical wizard, customize the domain. These steps clone the binaries and domain configuration. If the extension is needed, perform it after cloning in the WebLogic web-based console.
C.
In the Enterprise Manager, find the domain to be cloned. Choose "Clone WebLogic Domain" from the context menu. In the graphical wizard, customize and extend the domain if it is needed. These steps clone the binaries and domain configuration.
D.
In the Enterprise Manager, find the domain to be cloned. Choose "Clone WebLogic Domain" from the context menu. These steps clone the binaries and domain configuration. If the customization or extension is needed, complete that after cloning in the WebLogic web-based console.
E.
In the file system, copy the domain structure of the configuration directory and paste it in the new location. Modify configuration files for address and port. If further customization is needed, open the WebLogic web-based console and perform these modifications.
Answer:
C
Explanation:
Explanation:
The Clone WebLogic Domain option launches a wizard that enables you to clone a WebLogic Domain from an existing reference domain that is already discovered with Cloud Control. It allows you to clone the Middleware Home and its binaries, and the domain configuration.
*If you selected the Cloning a WebLogic Domain option, the Middleware Provisioning: Domain Configuration page appears. This page contains a set of links to several pages where you can enter the properties that are most likely to be reconfigured like domain name, listen addresses for the administration server and managed servers, Node Manager/Machine configuration, and JDBC data sources.
Question 3
Identify three advantages of Active GridLink for RAC over multidata source.
Options:
A.
isolates WebLogic from RAC changes
B.
has a simple configuration
C.
enables statement caching
D.
performs faster failure detection and failover
E.
is supported in WebLogic Domain Templates
Answer:
A, B, D
Explanation:
Explanation:
A, B: With Active GridLink for RAC, WebLogic instances are isolated from RAC configuration changes, and DBAs only need to contend with a single data source rather than multiple data sources.
D: Active GridLink for RAC distributes work based on different backend node capacities, automatically detecting and adapting to overworked nodes and hangs. It enables smart load balancing across RAC nodes. This makes it easier to route traffic around node failures, enhancing availability and performance.
