Oracle WebLogic Server 12c: Administration I Questions and Answers

Question 1

Consider a domain that includes a Node Manager home directory. One way to enroll each Node Manager with your domain is with the WLST command nmEnroll().

Select the two scenarios where you do not need to use this command to perform the same task? (Choose two.)

Options:

A.

The Node Manager is on the machine where the domain was created by using the Configuration Wizard

B.

You create a managed server template by using the pack utility. Then create the domain by using the unpack utility on the new machine where Node Manager will run

C.

Use the administration console. Select the machine, then the Configuration and Node Manager tabs. Select “Enroll with the Domain.” Save and activate your changes

D.

Use the script enrollNodeManager.sh found under the WEBLOGIC_HOME directory in server/bin

Question 2

A WebLogic Server (WLS) domain was recently updated from WLS 10.3.6 to WLS 12.1.12.

What is the mode of operation of the Node Manager after the update and what is needed to keep the same behavior as in WLS 10.3.6?

Options:

A.

Nothing, Node Manager runs and behaves the same on both WLS versions

B.

Node Manager runs in “per machine” mode and nothing is needed to keep the same behavior.

C.

Node Manager runs in “per domain” mode and requires manual steps to return to “per machine” mode, used in WLS 10.3.6.

D.

Node Manager mode of operating and behavior can be selected in Reconfiguration Wizard.

Question 3

You are carrying out the RDBMS Security Store Configuration using the configuration Wizard

Which three actions can you perform with the Configuration Wizard during the process? (Choose three.)

Options:

A.

Create tables in the data store.

B.

Execute SQL scripts in WebLogic server’s server/lib directory.

C.

Populate the database tables with external LDAP users.

D.

Test the connection to a back-end database.

E.

Allocate tablespace for the data store.

Question 4

A web application is configured for in-memory replication and is deployed to a cluster. This cluster is distributed across two buildings on a university campus. For performance reasons, you require that session replication occur within the building whenever possible.

How do you implement this requirement?

Options:

A.

Disable the dynamic server list in the proxy plug-in.

B.

Configure the cluster to use multicast communication.

C.

Configure the application’s cookies parameters.

D.

Configure each server’s replication group.

Question 5

An application fails. The exception indicates that the JDBC data source cannot be found.

Identify two possible steps that you can perform to verify the data source’s availability. (Choose two.)

Options:

A.

Launch the JDBCDiagnostics utility.

B.

Verify the Dependencies attribute of the data source.

C.

View the target server’s JNDI tree in the console.

D.

Verify that the application and data source have the same target.

Question 6

You want to configure WebLogic Server transactions to be recoverable when a nonclustered managed server crashes, even if that crash is caused by an unrecoverable hardware failure. You want to run the managed server on different hardware, and have it recover the transactions that were in-progress at the time of the crash.

You also want to use the default store for transaction logs.

Which statement is true?

Options:

A.

This scenario is not possible. You must use the JDBC store to recover transactions from a crashed server.

B.

This scenario is not possible. You must use clustered managed servers to recover transactions from a crashed server.

C.

This scenario is common, and so the default configuration of the default store works.

D.

Before the crash, you need to update the path to the default store for the managed server. The path should be to some shared storage location.

E.

After the crash, obtain a copy of the managed server’s default store from the administration server. Move it to the same relative location on the new hardware before starting the managed server there.

Question 7

You are responsible for configuring a WebLogic domain to support an order processing application. This application will communicate with multiple JDBC data sources to fulfill each customer order. To maintain data integrity across these databases, work will be performed within a global transaction. However, you have learned that one of the data sources in the transaction does not have an XA driver.

Which option should you select on this non-XA data source to ensure that orders are still processed as global transactions?

Options:

A.

Ignore Heuristics

B.

Pinned to Thread

C.

One Phase Commit

D.

Logging Last Resource

E.

Test Connections on Reserve

C.

Increase the rotation time

D.

Create and use a custom log filter

E.

Decrease the rotation file size

Question 9

Options:

A.

Include the JAR file as an optional package

B.

Deploy the JAR file as an EJB

C.

Deploy the JAR file as a shared library

D.

Place the JAR file in the lib folder of the domain

E.

Deploy the JAR file to the administration server. All managed servers have access to their admin server

F.

Add the JAR file to the CLASSPATH of the domain servers by editing the domain’s seyDomainEnv.sh script

G.

Deploy the JAR file as another web application

Question 10
