Title : BEA8.1 Certified Architect:Enterprise Architecture

1. WSRP is an attractive option for web development because it decouples the deployment and delivery of applications. WebLogic Platform allows for the creation of WSRP-enabled portlets EXCEPT for which portlet type?
A. Struts
B. Pageflow
C. HTTP Web Service
D. JSR168 Java Portlet
E. JSP Portlets using a JPF
Answer: C

2. Smithers and Dithers’ architecture must accommodate multiple Web requests, which may demand various preprocessing and postprocessing activities. Which Design Pattern best describes a solution that meets this requirement?
A. Flyweight
B. View Helper
C. Front Controller
D. Composite View
E. Dispatcher View
Answer: C

3. Scenario: The activity diagram for FR004 details dependencies on other applications whose requirements are defined in separate use cases. A primary requirement for the new POS application is that it must accommodate future architectures and currently-unknown internal and external clients. Given the path defined by FR004’s activity diagram and the non-functional requirement, answer the following question. The activity diagram and use case specify that if an update to an EIS fails, the process must roll back the current transaction. Assuming that each update is asynchronously invoked, what is the best way to handle transaction rollback within this process?
A. Use a standard XA transaction employing two-phase commit
B. Define an explicit transaction boundary within the process definition
C. Use the transaction propagation facilities of J2CA and execute each update from the XA transaction context of the process
D. Use a compensating transaction after each callback from the EIS’ update operation that manually restores the affected data
E. Implement a custom exception path within the process that invokes the rollback method of the related global distributed transaction
Answer: E

4. Scenario: The Notify Merchandiser and Notify Inventory Control steps defined in FR004’s activity diagram should be invoked in parallel. Which of the following is NOT a valid architectural approach based on this use case requirement?
A. Send notification messages to two separate JMS Queues monitored by both consumers
B. Send one notification message to a single JMS Topic which maintains a separate subscription from both consumers
C. Send notification messages directly to two Message-driven EJB callback objects provided by both consumers
D. Send one notification message to a single JMS Topic which maintains a separate subscription from both consumers within a single XA transaction
E. Send two notification messages to a single JMS Queue using a JMS message selector by each consumer
Answer: C

5. Scenario: Use Case FR004 gives the requirements for the daily transaction upload that every store POS terminal must complete. The associated activity diagram provides the path through this use case. You decided to implement this functionality as a separate Java Process Definition using WebLogic Integration. Use this information to answer the following question. Given the requirements of FR004 for guaranteed message delivery, which architectural approach provides the best solution for maximum performance throughput?
A. Configure the store’s JMS server to use persistent message delivery using a JDBC backing store.
B. Configure the POS terminal’s JMS server to use persistent message delivery using a JDBC backing store.
C. Configure the POS terminal’s JMS server to use persistent message delivery using a file store as the message’s paging store.
D. Configure the store’s JMS server to use persistent message delivery using a file backing store. Use a common network mount point and a file directory on a RAID array.
E. Configure the POS terminal’s JMS server to use persistent message delivery using a file backing store. Use a common network mount point and a file directory on a RAID array.
Answer: D

6. Smithers and Dithers must now support interaction with business applications that use ebXML and RosettaNet B2B protocols. Which architectural approach would best satisfy this new requirement?
A. Publish WebLogic Portal JMX MBean APIs to each business partner
B. Design one or more WebLogic Server Messaging Bridges with J2CA adapters
C. Configure a Trading Partner Management repository with WebLogic Integration
D. Use WebLogic Workshop to wrap coarse-grained business functionality as Web Services
E. Use the Liquid Data View Builder to design and build custom queries for integrated data access
Answer: C

7. Smithers and Dithers will be using HP Openview for all SNMP management. Which of the following is NOT true concerning WebLogic Server’s SNMP capabilities?
A. The WebLogic SNMP agent supports both SNMPv1 and SNMPv2 protocols
B. The WebLogic SNMP agent can only run on a domain’s Administration Server
C. Each MBean attribute in the MIB is an SNMP managed object with a unique object identifier
D. The WebLogic SNMP agent can be configured to respond to simple GET and SET requests
E. The WebLogic SNMP agent can act as a proxy to other SNMP agents on the same machine
Answer: D

8. You have determined that your Web Applications will be deployed to a WebLogic cluster for high availability. In order to take advantage of HTTP session replication, which of the following is required?
A. All session data must be serializable
B. Replication Groups must be configured
C. One member of the cluster must be used as the proxy server
D. All members of the cluster must be located within the same subnet
E. At least two cluster members must be running on separate machines
Answer: A
