Question 14 – Objective 2 - Business Architecture
You have a business requirement to pull detailed customer data from both a legacy CRM
application and a legacy EJB application. You would like to implement a service that seamlessly
integrates these applications and can be easily consumed from within other process driven
services implemented with WebLogic Integration. Additionally you would like to enforce a
separate XA transaction boundary around both the invocation of the CRM application and the
EJB. Which option below allows this?

an application view control to invoke methods on the CRM application. Call both through
the Message Broker.
Question 15 – Objective 4 - Information Systems Architecture–Data
You have a business requirement to pull detailed customer data from both a legacy CRM
application and a legacy EJB application. The data models for both applications are well
defined; however there is some disparity between the data elements used by each application.
You are required to provide a solution that utilizes the necessary data required by each
application yet is still flexible enough to use additional data that may be needed by either
application at a later date. What is the best way to complete this requirement?
a) Create a secondary data model that is a union of the data models currently used by both
applications. Make changes to each application using the new, standardized data model.
b) Pass the complete data from one application to the next in XML format then use XSLT to
transform the data model to the target application.
c) Pass the complete data from one application to the next in XML format then use XQuery
to transform the data model to the target application.
d) Analyze the data passed between these two applications and all related applications.
Build a universal data model for these applications and apply either XSLT or XQuery to
transform the data for each application.
e) Analyze the data passed between these two applications and all related applications.
Define the data model as an XML Schema and use XML Beans to represent each
application’s data model.
Question 16 – Objective 4 - Information Systems Architecture–Data
You want to provide access to important, yet less frequently used operational support data and
Business Intelligence data to increase the agility of your data processes. The problem you are
facing is that some of the data in these stores aren’t currently replicated to your data
warehouse. You realize that changing the necessary data warehouse schema to collect this
additional data could up to a year. The fact that these systems aren’t used frequently doesn’t
really justify the extra development time and expense. What is one way you can include this
data, along with data in your existing warehouse into you data services tier?
a) Write a synchronization service that extract data from the data warehouse and combines
it with data extracted from the other data stores.
b) Employ a third part tool allowing you to create a virtual data warehouse representing the
non-replicated data stores.
c) Use Liquid Data to create a Unified Data Model containing the data from the data
warehouse and the non-replicated stores.
d) Create a separate off line data mart that extracts and synchronizes the data from the
data warehouse and non-replicated stores.
e) Create a separate data access service for the data warehouse and non-replicated stores
and synchronize them through a custom control.
Use the following scenario to answer the next four questions:
You have been given a requirement to create a nightly report showing total daily sales stats
from all of your company’s retail outlets. This report must be created by a service running as a
nightly batch process. The service must interface with the custom, legacy inventory system
running on your mainframe as well as a custom catalog application. The data in each of these
systems are stored in disparate formats, for example the mainframe application uses COBOL
copy books where the catalog application uses delimited data. Once the report is complete, it
must be sent via FTP to the inventory update service which will use the data to determine stock
levels and new shipments for each retail store.
Question 17 – Objective 5 - Infrastructure/Technology Architecture
What is the best approach for starting the service as a batch process?
a) Implement the service as a JPD and configure the start node to respond to a timer
event.
b) Implement the service as a cron job.
c) Implement the service as a JMS subscriber.
d) Implement the service as a JPD and configure the start node to respond to a Message
Broker channel.
e) Implement the service as a JPD. Configure the service’s SLA to the time you want the
batch job to run. Use the overdue node to catch the SLA violation and start the process.
Question 18 – Objective 4 - Information Systems Architecture–Data
Given the complexity and incompatibility of the data from the COBOL application what is the
best choice to transform this data?
a) Using XQuery from a transformation control.
b) Using XSLT from a transformation control.
c) Using an XMLObject created from an MFL file generated by Format Builder.
d) Using an XMLBean generated from a schema defining the copybook data.
e) Using a copybook to XML converter.
Question 19 – Objective 4 - Information Systems Architecture–Data
Which option below best describes how to combine the data from the inventory system
and catalog application?
a) Convert both data models to XML Schemas and use WebLogic Workshop’s visual data
mapper to define the transformation.
b) Convert both data models to a binary stream, parse the stream and convert into an MFL
file.
c) Create two separate MFL files for each application. Import the XML documents
generated from the MFL files into a schema project.
d) Create two separate MFL files for each application. Import the XML documents
generated from the MFL files into a schema project. Create an XMLBean for each
document and use them to define the transformation using WebLogic Workshop’s visual
data mapper.
e) Create two separate MFL files for each application. Import the MFL documents into a
schema project. Create an XMLObject for each document. Create an XMLBean from
each XMLObject and use them to define the transformation using WebLogic Workshop’s
