Questions # 4:

Examine the domain diagram:

Question # 4

You are asked to write a WLST script that will print the current available heap size for server04.

Assuming:

    all servers are running

    you have just started an offline, interactive WLST session

    a domain-scoped node manager is running on each machine, listening oт port :5556

    the username/password “weblogic/Welcome1” maps to a valid domain administrator and Node Manager client

Which two code options will accomplish this task? (Choose two.)

Options:
A.

connect(‘weblogic’,‘Welcome1’,‘host00.acme.com:7001’)domainRuntime()x = getMBean(‘/ServerRuntimes/server04/JVMRuntime/server04’)print x.getHeapFreeCurrent()

B.

connect(‘weblogic’,‘Welcome1’,‘host02.acme.com:7201’)serverRuntime()x = getMBean(‘/JVMRuntime/server04’)print x.getHeapFreeCurrent()

C.

connect(‘weblogic’,‘Welcome1’,‘host00.acme.com:7001’)serverRuntime()x = getMBean(‘/JVMRuntime/server04’)print x.getHeapFreeCurrent()

D.

nmConnect(‘weblogic’,‘Welcome1’,‘host02.acme.com:5556’)serverRuntimes()x=getMBean(‘/server04/JVMRuntime/server04’)print x.getHeapFreeCurrent()

E.

nmConnect(‘weblogic’,‘Welcome1’,‘host00.acme.com:5556’)domainRuntime()x=getMBean(‘/ServerRuntimes/server04/JVMRuntime/server04’)print x.getHeapFreeCurrent()

Expert Solution
Questions # 5:

Review the following WLST commands.

Question # 5

What happens when these commands are executed? (Choose the best answer.)

Options:
A.

A diagnostic module named mymodule is created in the domain configuration file and it is enabled on cluster1.

B.

A JMS module named mymodule is created without changing the domain configuration file and it is enabled on cluster1.

C.

A diagnostic module named mymodule is created without changing the domain configuration file and it is enabled on cluster1.

D.

A JMS module named mymodule is created in the domain configuration file and it is enabled on cluster1.

Questions # 6:

In order to leverage replication and high availability features of your back-end database, among other benefits, you are configuring a JDBC TLOG store to persist transaction logs.

Since something went wrong during the setup of the TLOG, you are reviewing the configuration considerations for TLOG.

Which two guidelines are true for configuring JDBC TLOG stores? (Choose two.)

Options:
A.

Only one JDBC TLOG store can be configured per WebLogic Server.

B.

JDBC TLOG stores should only be configured for RAC databases.

C.

Only globally-scoped (not application-scoped) data sources can be targeted to a JDBC TLOG store.

D.

Multiple WebLogic Servers can share the same JDBC TLOG store.

Expert Solution
Questions # 7:

You have a multithreaded application that looks up the WebLogic JMS ConnectionFactory object from the JNDI tree.

Which statement is correct in this scenario? (Choose the best answer.)

Options:
A.

It is not permitted. A multithreaded application cannot access the ConnectionFactory object.

B.

The access to ConnectionFactory object MUST be synchronized.

C.

The ConnectionFactory object can be referenced in a multithreaded application without any special considerations.

D.

Multiple threads trying to use the ConnectionFactory object simultaneously will throw an exception.

E.

In a multithreaded scenario, connection objects cannot be safely created from the ConnectionFactory.

Expert Solution
Questions # 8:

You are implementing leasing functionality within your environment to ensure exclusive ownership of a cluster-wide entity.

Which type of leasing requires that Node Manager is configured and running? (Choose the best answer.)

Options:
A.

high-availability database leasing

B.

high-consensus leasing

C.

non-database consensus leasing

D.

high-availability in-memory leasing

Expert Solution
Questions # 9:

What will occur once you execute the shrink() method on that JDBCDataSourceRuntimeMBean?

Options:
A.

The number of connections in the pool will be reduced to the greater of either the current number of connections in use or to the minCapacity property setting.

B.

The number of connections in the pool will be reduced to the current number of connections in use regardless of the minCapacity property setting.

C.

The number of connections in the pool will be reduced to the minCapacity property setting regardless of the current number of connections in use.

D.
