Exam 1z0-108: Oracle WebLogic Server 10g System Administration

To avoid large buffer attacks from different HTTP clients accessing the various Fulfillment web applications:

Scenario : While you are setting up a WebLogic 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. To avoid large buffer attacks from different HTTP clients accessing the
various Fulfillment web applications:

What happens if all the servers hosted in the London cluster crashes in the middle of an http session update?

Refer to the Exhibit.

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?

Which WLST command will give you access to the current configuration, so that you can make the change?

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?

This can be achieved by:

Scenario : While you are setting up a WebLogic Server domain for a fulfillment service application
you have the following requirements: The Fulfillment application should be scalable and highly

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. When retailers access their website (using DNS name), automatically
they should be taken to the Stock Control Management web application within the Fulfillment
Service. This can be achieved by:

To deliver the messages from the Stock Control Application to the Warehousing Application without directly connecting to MQ-Series, configure:

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 backend 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 deliver the messages from the Stock Control
Application to the Warehousing Application without directly connecting to MQ-Series, configure:
