NO.2 Scenario : The Stock Control Application you are going to deploy to a cluster of WebLogic Managed
Servers requires a JMS destination to asynchronously deliver the messages to the back-end Warehousing
Application. To distribute the messages across the cluster, you decided to configure the distributed
destination. Also the Warehousing Application is a legacy application written to implement a proprietary MQ
API connecting an MQ-Series server. The Stock Control Application is implemented as a web application on
a WebLogic cluster delivering the message to the distributed destination. The cluster has three Managed
Servers hosted on two high powered machines and one low range/powered machine.
To distribute the physical destinations unevenly across the clustered WebLogic Managed Servers so that
the high-powered machines can receive more messages than the low-powered machines, configure the
distributed destination with:
A. "Allocate Members Uniformly" set to false and manually select more physical destinations from the
high-powered machines
B. "Uneven Distribution" set to true and select all the physical destinations
C. "Uniform Distribute Destination" set to true and select all the physical destinations from the high-powered
and low- powered machines
D. "Load Balancing Policy" set to Random and select only the destination from the high-powered machine

NO.3 Scenario : Consider an upgrade requirement from pre-WebLogic Server 10.x to the WebLogic Server
10.x. Since the administration scripts in the prior version used WebLogic Ant tasks for creation and
deployment, the team decides to use the Ant build.xml approach and extend this to the current version of
the server.
Which of the following about the Ant task wlserver is INCORRECT?
A. wlserver can be used to start, reboot or shut down server instances.
B. wlserver can be used to connect to existing server instances.
C. wlserver can be used to create a multiple server domain configuration.
D. wlserver can be used to create a single server domain and to connect to the server.

NO.4 Which of the following is true about JMS Quota resources in WebLogic Server 10.x?
A. Quota settings can be shared across multiple JMS destinations so that they can compete.
B. Quota settings are defined on the JMS connection factory level.
C. Quota settings can be used to limit the number of JMS Connections to a JMS Server.
D. Quota settings can be shared across multiple WebLogic domains.

NO.5 Click on the Exhibit button.
Scenario : A multi-network cluster, say WAN-1 and WAN-2, is being created that will provide WAN HTTP
session failover. The WAN-1 cluster is located in London and the WAN-2 cluster is located in New York and
is connected via a slow interconnect. The client request passes through a Global load balancer which load
balances the request to local load balancers which eventually pass the load to WebLogic Server instances
in the cluster. Four WebLogic Server instances will be running on each cluster distributed on two physical
machines, two WebLogic instances per physical machine. A database is configured on each cluster for
HTTP Session state failover between the clusters.
How can you configure in-memory session replication on the London cluster?
A. The web application deployment descriptor, weblogic.xml needs to have the persistent-store-type set to
memory.
B. The web application deployment descriptor, weblogic.xml needs to have the persistent-store-type set to
replicated.
C. The web application deployment descriptor, weblogic.xml needs to have the persistent-store-type set to
cookie.
D. The web application deployment descriptor, web.xml needs to have the persistent-store-type set to
memory.
E. The web application deployment descriptor, web.xml needs to have the persistent-store-type set to
replicated.

NO.6 Click on the Exhibit button.
Scenario : A multi-cluster architecture, with two geographically separated clusters (WAN-1 and WAN-2), is
being created. It will provide cross-cluster WAN HTTP session failover. The WAN-1 cluster is located in
London and the WAN-2 cluster is located in New York and is connected via a slow interconnect. The client
request passes through a Global load balancer which load balances the request to local load balancers
which eventually pass the load to WebLogic Server instances in the cluster. Four WebLogic Server
instances will be running on each cluster distributed on two physical machines, two WebLogic instances per
physical machine. A database is configured on each cluster for HTTP Session state failover between the
clusters.
What happens if all the servers hosted in the London cluster crashes in the middle of an http session
update?
A. The session will be regenerated on the New York cluster without any session data loss, and a new
primary server will be created using the secondary session data.
B. The session will be regenerated on the New York cluster but there could be a loss of session data; a new
primary server will be created using the last known secondary session data.
C. The session will not be regenerated on any cluster; the user will be redirected to the New York cluster to
create a new session.
D. The session will be regenerated if the primary server on the London cluster is restarted.
E. Both b and d

NO.7 In a multi-server WebLogic domain, monitoring the JVM statistics showed frequent full garbage
collections (gc) on one of the server instances. Which one of the following would greatly reduce the
frequency of full gcs?
A. Increasing the young object space in the heap
B. Turning the -verbosegc flag on
C. Adding more servers to the domain
D. Running more servers per machine

NO.8 Scenario : A single tier WebLogic cluster is configured with six Managed Servers. An Enterprise
application is deployed to the cluster with a web application and EJBs packaged in the same EAR file.
An EAR file is being deployed to the cluster using two-phase deployment. Which of the following is true if
one of the Managed Servers is NOT started in the cluster?
A. First and second phase deployment will be completed on all remaining instances in the cluster.
B. First phase deployment will not be completed on the remaining instances in the cluster.
C. First phase deployment will be completed but the second phase will not be completed on the remaining
instances in the cluster.
D. First and second phase deployment will not be completed if enforceClusterConstraints is set to true for
the Deployer.
E. Both a and d
