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.

*

JNDI (Java Naming and Directory Interface), which provides a resource lookup facility. JMS resources such as connection factories and destinations are configured with a JNDI name. The runtime implementations of these resources are then bound into JNDI using the given names.

*

(E) WebLogic persistent storage (file store or JDBC-accessible) for storing persistent message data.

The following figure illustrates the WebLogic JMS architecture.

Correct Answer: B

The WebLogic Server-specific deployment descriptor weblogic.xml. If your Web application does not

contain a weblogic.xml deployment descriptor, WebLogic Server automatically selects the default values of

the deployment descriptor elements.

Note:

A Web archive (WAR file) contains the files that make up a Web application. A WAR file is deployed as a

unit on one or more WebLogic Server instances. A WAR file deployed to WebLogic Server always includes

the following files:

*

One servlet or Java Server Page (JSP), along with any helper classes.

*

An optional web.xml deployment descriptor, which is a Java EE standard XML document that describes the contents of a WAR file.

*

A weblogic.xml deployment descriptor, which is an XML document containing WebLogic Server-specific elements for Web applications.

*

A WAR file can also include HTML or XML pages and supporting files such as image and multimedia files.

Correct Answer: ABDF

Use the Administration Console to:

*

(A) Configure, start, and stop WebLogic Server instances

*

Configure WebLogic Server clusters

*

(D) Configure WebLogic Server services, such as database connectivity (JDBC) and messaging (JMS)

*

Configure security parameters, including managing users, groups, and roles

*

Configure and deploy your applications

*

Monitor server and application performance

*

View server and domain log files

*

View application deployment descriptors

*

(F) Edit selected run-time application deployment descriptor elements

*

(B) Control (start, stop, and restart) standalone Coherence cache servers

*

(B) Create and configure Coherence clusters

Incorrect:

Not C: The separate Domain Template Builder is used for creating Domain Templates.

Correct Answer: ACD

Comparing File Stores and JDBC-accessible Stores

The following are some similarities and differences between file stores and JDBC-accessible stores:

*

(A) JDBC stores may make it easier to handle failure recovery since the JDBC interface can access the database from any machine on the same network. With the file store, the disk must be shared or migrated.

*

The default persistent store can only be a file store. Therefore, a JDBC store cannot be used as a default persistent store.

*

Both have the same transaction semantics and guarantees. As with JDBC store writes, file store writes are guaranteed to be persisted to disk and are not simply left in an intermediate (that is, unsafe) cache.

*

Both have the same application interface (no difference in application code).

*

(not B, not E) All things being equal, file stores generally offer better throughput than a JDBC store.

/ If a database is running on high-end hardware with very fast disks, and WebLogic Server is running on slower hardware or with slower disks, then you may get better performance from the JDBC store.

*

File stores are generally easier to configure and administer, and do not require that WebLogic subsystems depend on any external component.

*

File stores generate no network traffic; whereas, JDBC stores generate network traffic if the database is

on a different machine from WebLogic Server.
