Question 3.
A domain configuration has been transferred from an old development server to a new machine.
It had been hoped that the domain files could just be transferred from one machine to another, but it is now understood that certain parameters are dependent on the local configuration. The Listen Address for the admin server is not valid for the new machine and needs to be changed before the admin server can be started.
You start WLST in off-line mode to rectify the problem.
Which WLST command will give you access to the current configuration, so that you can make the change?
A. connect
B. load Domain
C. read Domain
D. load Properties
Answer: C
Question 4.

"commands.
B. Node Manager can only restart a server that was started via Node Manager.
C. Node Manager can restart the Managed Server in Managed Server Independence (MSI)
mode.
D. By default, Node Manager automatically restarts the Managed Server instance under its
control that failed.
Answer: A
Question 5.
WLST life cycle commands are used to manage the life cycle of a server instance and its services. If the requirement is to use the migrate command, which of the following is INCORRECT?
A. Migrate command can be used to migrate a JMS server to another server within a cluster only.
B. For JTA migration, the source server has to be down for the migrate command to succeed.
C. For JMS Service, migration to another server can happen only on a running server.
D. The migration type server option can be used to migrate all services for a particular server.
Answer: C
Question 6.
Scenario: The Stock Control Application you are going to deploy to a cluster of Web Logic 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 Web Logic 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 Web Logic 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 selects only the destination from the high-powered
machine
Answer: A
Question 7.
Scenario: You have made the decision to migrate all your operations onto Web Logic 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 Web Logic Server 9.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 Web Logic 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.
In the future, each department will have its own schema within the Oracle database and the developers are writing their code with this in mind. However, for now, it has been decided to store all data in a single, company-wide schema.
Which of the following approaches will make a future move to multiple schema simple, while making the most efficient use of resources today?
Exhibit:
A. Deploy an application-scoped Data Source module with each application.
B. Deploy a Data Source system module and assign it multiple JNDI names.
C. Deploy each department's application to its own Web Logic server.
D. Deploy a Data Source system module for each department's application.
Answer: B
Question 8.
Which two of the following roles can you use the Web Logic SNMP agent for?
A. Respond to simple GET requests from an SNMP manager.
B. Allow SNMP managers themselves to set the values of managed objects or invoke
management operations.
C. Listen for specific log messages and send trap notifications to SNMP managers when Web
Logic Server generates them.
D. Use WLST scripts to poll Web Logic Server resources periodically and send trap notifications
to SNMP managers when the resources change in a way that you specify.
Answer: A, C
Question 9.

Answer: A
Question 10.
Web Logic store-and-forward service is used for:
A. Storing and forwarding the configuration reliably to all the Managed Servers in a cluster
B. Storing log messages and forwarding them to the administration server for creating the
Domain Log
C. Storing and delivering JMS messages reliably between applications across Web Logic Server
9.x instances
D. Storing
Question 11.
Scenario : While you are setting up a Web Logic Server domain for a fulfillment service application you have the following requirements: The Fulfillment application should be scalable and highly available; different users will use the application using a different DNS name. This application is also exposed to some business partners using other protocols in addition to HTTP and this site also needs to be configured for transport level security. Different certificates should be installed in the server for different clients (using different DNS names). Even the site should withstand hardware NIC failures too.
How can Web Logic Server leverage the multiple physical NICs available on the hardware and be configured to withstand NIC failures so that customers will have high-availability for their applications?
A. By configuring HTTP Parameters for the server
B. By configuring network channels for different NICs
C. By deploying and targeting different applications on different NICs directly
D. By enabling the Managed Server Independence mode flag for the respective Web Logic
Server.
Answer: B
Question 12.
Which statement is true about SSL configuration?
A. SSL can be configured only at the domain level. All the servers in that domain use same SSL
configuration.
B. SSL can be configured at the server level. All the servers in the domain can be configured to
use their own SSL settings.
C. SSL can be configured at the cluster level. All the servers that are part of the clusters use the
same SSL configuration.
D. Once you configure SSL, the normal listen port will be disabled and cannot be used while the
SSL port is enabled.
Answer: B

A. Create a WLST off-line script using duplicate Domain and send it to the development team to
recreate the server configuration.
B. Send all server configuration files and have them recreate the server configuration using
WLST parse scripts.
C. Create a Web Logic Server domain template using WLST and send it to the development team
to recreate the configuration.
D. Use the Web Logic admin console to save the domain configuration and send it to the
development team.
Answer: C
Question 19.
Scenario: Consider a b2b commerce application hosted on a Web Logic 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.
To prevent all threads from getting stuck, which of the following approaches would you adopt?
