NO.1 Scenario : Consider a b2b commerce application hosted on a WebLogic cluster with JMS messages
being received, processed, and forwarded to external servers. The server log indicates a potential stuck
thread problem where threads are continually getting stuck and JMX monitoring indicates a continuous
backlog of pending messages that could be due to any of the in-flight messages, delayed messages, or
messages being inhibited from delivery.
The recommended approach for setting the number of execute threads would be:
A. Set the default thread pool max value to match load expectations
B. Use an iterative approach to set the max thread count value
C. Set this value the same as the max connections value set on database connections
D. Leave this setting to be handled by the Work Manager by configuring MaxThreadsConstraint
Answer: D

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.

replicated.

NO.8 Click on the Exhibit button.
Scenario : You have made the decision to migrate all your operations onto WebLogic Server. An
application has been chosen from each department for the initial phase of migration ?one from each of
Sales, Marketing, Accounts, and Customer Service. The applications will be deployed as individual EAR
files to a cluster of WebLogic Server 10.x instances, each with a pool of connections to an Oracle 10g
database that provides corporate and departmental data services. The database team hopes to upgrade
the database to use Oracle RAC (Real Application Clusters) shortly, which will require you to configure
multiple sets of connections. Connectivity to the existing Service Engineer Dispatch system is via a JMS
message bridge. When a service engineer calls in with a report, a message is sent via JMS to the
Customer Service application deployed in WebLogic Server. The customer record in the Customer
Service database must be updated with details from the message. It is important that the message is not
lost because the call management system is not able to resend messages. To address this, the Customer
Service application is accessing a persistent JMS Queue using an XA compatible connection factory.
The database security team insists that any use of the corporate Oracle database can be traced to the
individual user that made the request. How can this be achieved when using WebLogic JDBC Data
Sources?
A. Set the Enable Credential Mapping property for the Data Source.
B. Set Initial Capacity to zero, so each user creates a new connection.
C. Set the value of user to {WLS_USER} in the Properties field.
D. This can only be done using application code.
E. This cannot be done because Data Sources connect using a single username.
