Question #16
Assume that you would like to clone an existing WebLogic Domain and enable some customizations. What scenario would you choose?
  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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

Correct Answer:
C
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 #17
Which three scenarios are true about Domains?
  1. A
    Domains can be created using the Configuration Wizard.
  2. B
    Domains can be created using WLST.
  3. C
    Domain configuration files are located in the WebLogic home directory.
  4. D
    Domains can be created based on a domain template.

Correct Answer:
ABD
A: a WebLogic domain can be created by using the Configuration Wizard in graphical mode.
B: WLST enables you to create a new domain or update an existing domain
D: A domain template is a JAR file that contains domain configuration documents, applications, security data, startup scripts, and other information needed to create a domain.

Question #18
Identify three components of the WebLogic JMS architecture.
  1. A
    JMS Server
  2. B
    JMS Module
  3. C
    Node Manager
  4. D
    Queue Manager
  5. E
    Persistent Store

Correct Answer:
ABE
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.

http://docs.oracle.com/cd/E13222_01/wls/docs103/jms/fund.html
(see the Major Components).

Question #19
How can you configure High Availability for interacting with a non-Oracle database using WebLogic?
  1. A
    Configure multiple physical data sources and reuse the same JNDI name for each.
  2. B
    Use the "compatibility" option of Active GridLink to enable compatibility with non-Oracle databases.
  3. C
    Configure a single physical data source for each node in a database cluster and wrap it using Multi Data Source.
  4. D
    Configure a Data Source Group that contains a physical connection pool to each node in the database cluster.

Correct Answer:
C
Note:
* A multi data source can be thought of as a pool of data sources. Multi data sources are best used for failover or load balancing between nodes of a highly available database system, such as redundant databases or Oracle Real Application Clusters (Oracle RAC).
* (not B) A single GridLink data source provides connectivity between WebLogic Server and an Oracle Database service, which may include multiple Oracle RAC clusters
* High Availability Storage Solutions
If you have applications that need access to persistent stores that reside on remote machines after the migration of a JMS server or JTA transaction log, then you should implement one of the following highly-available storage solutions:
/ File-based stores (default or custom)Implement a hardware solution, such as a dual-ported SCSI disk or Storage Area Network (SAN) to make a file store available from shareable disks or remote machines.
/ JDBC-accessible storesConfigure a JDBC store or JDBC TLOG store and use JDBC to access this store, which can be on yet another server. Applications can then take advantage of any high-availability or failover solutions offered by your database vendor. In addition, JDBC stores support GridLink data sources and multi data sources, which provide failover between nodes of a highly available database system, such as Oracle Real Application Clusters (Oracle RAC).

Question #20
Which feature is enabled when you start a WebLogic server with the –DserverType=wlx option?
  1. A
    JDBC
  2. B
    JCA
  3. C
    JMS
  4. D
    EJB
  5. E
    Java EE

Correct Answer:
A
-DserverType={"wls" | "wlx"}
Specifies the Server Type, which determines the set of services that are started in the server runtime.
The default is "wls", which starts all WebLogic Server services, including EJB, JMS, Connector, Clustering, Deployment, and Management.
The "wlx" option starts a server instance that excludes the following services, making for a lighter weight runtime footprint:
* (not D) Enterprise JavaBeans (EJB)
* (not B, not E) Java EE Connecter Architecture (JCA)
* (not C) Java Message Service (JMS)
