Question 1

My JMS file store size has grown very large and is using up a significant chunk of the disk. I need to reduce the file size during the maintenance window without impacting any relevant information.

Which utility enables me to do this? (Choose the best answer.)

Correct Answer: B. weblogic.store.Admin
Explanation:

To open the persistent store administration utility from a Java command line, type the following:

> java weblogic.store.Admin

Here is an example of using the compact command to compact the space occupied by a file store in the mystores directory.

> storeadmin->compact -dir c:\mystores -tempdir c:\tmp


Question 2

You are planning to use WebLogic JMS for implementing my enterprise messaging architecture. Which messaging paradigm is invalid in this context? (Choose the best answer.)

Correct Answer: C. Datagram messaging

Question 3

Review the diagram below. It depicts the following:

Assuming the next request for an HTTP session attribute is a new attribute that is not stored in a near-cache, the client's session attribute is fetched from the remaining storage-enabled server in cluster 2.

Why is the session attribute retrieved from this other server's cache? (Choose the best answer.)

Correct Answer: A. Coherence*Web stores sessions in a distributed cache on the back end and the request fails over to the new location after partition re-balancing takes place.

Question 4

Your development team is considering several different types of new applications. You have been asked to advise them concerning which types can be deployed in WebLogic Server leveraging the Production Redeployment feature.

Which application deployment type is NOT supported for Production Redeployment? (Choose the best answer.)

Correct Answer: A. enterprise applications (EAR) that contain a Coherence Grid Archive (GAR) module

Question 5

You want to create a WebLogic Server (WLS) Work Manager with a Response Time Request Class of one second. You start to create the following WLST script:

Which two can replace the missing sequence to finish this script? (Choose two.)

Correct Answer: A. cmo.addTarget(getMBean('/Servers/ManagedServer'))cd('edit:/SelfTuning/wls_domain/WorkManagers/MyWorkManager')cmo.setResponseTimeRequestClass(getMBean('/SelfTuning/wls_domain/ResponseTimeRequestClasses/MyResponseTime')); D. managedServer=getMBean('/Servers/ManagedServer')cmo.addTarget(managedServer)cd('edit:/SelfTuning/wls_domain/WorkManagers/MyWorkManager')cmo.setResponseTimeRequestClass(getMBean('/SelfTuning/wls_domain/ResponseTimeRequestClasses/MyResponseTime'))

Question 6

A current production WebLogic Server (WLS) domain needs to be upgraded without affecting the users. What are the five steps to follow for a Rolling Update? (Choose five.)

Correct Answer: A. Back up the contents of your domain.; C. Shut down the servers in a single machine.; D. Repeat the process for all machines in the domain.; E. Restart the servers in the machine.; G. Upgrade the servers in the machine.
Explanation:

A: Before you begin the upgrade process, make sure that you take any necessary precautions such as:

* Back up your applications, database schema, other application data, and domains.

* If required, obtain latest third party plug-ins or components that are compatible with required non-Oracle components. For example, Apache Web Server libraries.

CGED: The rolling upgrade process includes stopping the Administration Server, installing the upgrade, restarting the Administration Server, and then doing the same for each Managed Server in the cluster (machine).


Question 7

Which two automatic migration scenarios require node manager for all migratable services? (Choose two.)

Correct Answer: A. Consensus leasing; C. Database leasing with pre and post migration scripts
Explanation:

When using automatic service migration, the Node Manager is required to get health monitoring information about the member servers involved, as follows:

* Consensus leasing -- Node Manager must be running on every machine hosting managed servers within the cluster.

* Database leasing -- Node Manager must be running on every machine hosting managed servers within the cluster only if pre/post-migration scripts are defined. If pre/post-migrations are not defined, then Node manager is not required.


Question 8

You need to make sure that a JMS Message never expires.

What value should you set for the JMSExpiration header? (Choose the best answer.)

Correct Answer: A. 0
Explanation:

WebLogic JMS calculates the JMSExpiration value as the sum of the application's time-to-live and the current GMT. If the application specifies time-to-live as 0, JMSExpiration is set to 0, which means the message never expires.


Question 9

Which three Weblogic server entities can be set up for service level migration? (Choose three.)

Correct Answer: A. JMS Server; C. JTA Transaction Recovery Service; D. User Defined Singleton Service
Explanation:

AC: WebLogic Server migration framework provides infrastructure and facilities to perform the manual or automatic migration of JMS-related services and the JTA Transaction Recovery Service.

D: WebLogic Server supports the automatic migration of user-defined singleton services.

Automatic singleton service migration allows the automatic health monitoring and migration of singleton services. A singleton service is a service operating within a cluster that is available on only one server at any given time.


Question 10

Examine the domain diagram:

Assume all servers are up and running and you have just started an offline WLST interactive session. Assume further that the username/password ''weblogic/Welcome1'' maps to a valid administrator.

You type two lines of WLST code:

connect('weblogic','Welcome1','host02.acme.com:7101')

print cmo.getType() + ':' + cmo.getName()

What will be printed? (Choose the best answer.)

Correct Answer: A. Domain:TestDomain
Explanation:

Example: The following example displays information about the current MBean, cmo.

wls:/mydomain/serverConfig> cmo.getType()

'Domain'
