Title : BEA SOA Foundations Exam

1. What is the purpose of a Reference Architecture?
A. To provide a frame of reference for discussion of enterprise architecture concerns.
B. To provide linkage between the architecture of a given enterprise and certain of the enterprise architecture frameworks, such as TOGAF or
Zachmann.
C. To define the reference material from which answers to questions about enterprise architecture may be drawn.
D. To provide a comprehensive enterprise architecture that constitutes the correct, best practices-based approach to constructing a modern
enterprise.
Answer: A

2. How is SOA different from previous approaches involving the sharing of information assets? (Choose all that apply.)
A. SOA is an enterprise architecture approach that does not specify a given technology or vendor solution.
B. SOA embodies the concept of run-time, rather than development-time or code level reuse.
C. SOA provides detailed specifications meant to provide a maximum of assurance of interoperability among supporting technologies and vendor
solutions.
D. The basis of SOA in XML and other standards provides true platform agnosticism.
Answer: ABD

3. Which of the following provides the best definition of SOA?
A. SOA is a software engineering paradigm that prescribes the creation of loosely coupled interfaces between the consumers of functionality and
the applications that represent that functionality.
B. SOA is a collection of technologies like enterprise service bus and Web Service management that facilitate the delivery of enterprise
functionality as a set of services.
C. SOA is an IT strategy that organizes the discrete functions contained in enterprise applications into interoperable, standards-based services
that can be combined and reused quickly to meet business needs.
D. SOA is a collection of standards, best practices, architectural models, and software development methodologies, principally based on Web
Services, which may be incorporated into enterprise software engineering to provide information technology to an enterprise in a
standards-based way.
Answer: C

4. When is SOA NOT an appropriate strategy? (Choose all that apply.)
A. When the applications in a given enterprise are necessarily stand-alone, and thus would not benefit from a shared services approach.
B. When the political boundaries among lines of business and their related IT functions are insurmountable, making sharing of functionality as
services impossible.
C. When the information systems in a given enterprise are homogeneous from a technological perspective and thus the sharing of functionality
among them is essentially built into their construction.
D. When enterprise business processes are widely distributed across the information systems for separate lines of business and are embedded
in the integration among those systems.
E. When application lifecycles are very short, and thus the effort to share functionality among them cannot be offset by gains from reuse.
F. When a given enterprise has dozens or hundreds of information systems for which the exposing of functionality from those systems as
services would be an extremely complex operation.
Answer: ACE

5. The aims of an SOA Program include: (Choose all that apply.)
A. The establishment of governance to standardize the way that functionality is delivered and deployed for use by the entire enterprise.
B. The delivery of enterprise architecture that facilitates the sharing of functionality as services in a way that is measurable and manageable and
meets operational goals.
C. The establishment of governance to standardize the way that enterprise information systems are coded.
D. Providing accountability to the business for the translation of business requirements into information technology.
E. The synthesis of business strategy and goals and the delivery cycles of projects into a roadmap for the creation and deployment of shared
services.

Exam : BEA Systems 0B0-108
Title : BEA9 Certified Administrator:System Adminstration Exam

1. 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 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 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 team informs you that they have now implemented Oracle Real Application Clusters (RA for the Customer Service database, and applications should connect to a second database node if the primary node is unavailable. You set up a Multi Data Source in Failover mode, which is configured to use two Data Sources PrimaryDS and SecondaryDS, each connecting to one Oracle RAC node. WebLogic Server will fail over to SecondaryDS if a connection test to PrimaryDS fails. Under what other condition will this happen by default (that is, with no additional options checke)?
A. If a connection to PrimaryDS is not released within Statement Timeout seconds.
B. If all the connections to PrimaryDS are in use.
C. If the administrator has suspended the PrimaryDS Data Source.
D. Failover will only occur if a connection test fails for a PrimaryDS connection.
Answer: C

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?
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 WebLogic server.
D. Deploy a Data Source system module for each department’s application.
