Question8: A customer wants to build an executive dashboard using information stored in a CICS application with data in legacy files, as well as customer profiles from a third party service. The IT department wants to build a data warehouse, but management is concerned about the expense and duration of this approach. Which is a viable, service-enabled alternative?

Question9: An SOA project implementation is underway in a large government organization. The development, testing, staging, and production environments have been installed and configured. Each environment consists of an Enterprise Service Bus (ESB), a registry and repository, a Web server, application servers, and Business Process Engine (BPEL). With only weeks before the project goes live with a business critical application, what should be recommended?

Question10: A bank has decided to rewrite their payment system from CICS/VSAM to SOA/J2EE/DB2 to easily adapt to a rapidly changing market, improve reporting capability and comply with a corporate edict to migrate off CICS/VSAM. The payment process is large and complex and includes three major sub-processes (Validation, Sanctions, and Disbursement) as well as additional supporting processes (e.g. Advising, Printing, and Reporting.) The Solution Architect has determined the entire project will take more than two years. The customer requires initial results within six months. What is the first step in the roadmap that should be suggested to the client?

Question11: A rapidly growing retail company recently outsourced their package delivery to a very reputable package delivery company. The two companies are integrated using SOA and Web services.

Which portion of the SOA Foundation is the focus to resolve this issue?

Question12: Which statement about SOA service design is true?

Question13: An organization has a large investment in legacy technologies (such as CICS and IMS) supporting applications that provide their core business transactions and data access. The Solution Architect believes significant value exists in providing interoperable or open standard, service-based access to those transactions (e.g., transactions that query account balance, create orders, schedule or track deliveries, query stock levels.) Which solution pattern should be considered by an Architect for providing service-based access to legacy systems?

Question14: A retail online commerce company uses SOA to create internal applications for its call centers, partners, and customers. As they matured, they began to look at establishing SOA governance and enlisted the services of an SOA Designer. After an audit of the current environment, it was found that they were achieving very low reuse of services and data entities. Further investigation revealed that duplicate services and data entities were being created. In which phase of the SOA Governance and Management Method should this problem have been initially addressed and which action should have been taken?

Question15: A telecom company has a Service Level Agreement (SLA) that requires Customer Service Representatives (CSRs) to respond to customer inquiries within 10 minutes.

Which portion of the SOA Foundation is central to the transformation of this system?

Question17: An SOA project consists of services deployed in a heterogeneous distributed environment that includes an Enterprise Service Bus (ESB). When adding a requirement for routing management, how should it be implemented?

Question18: A manufacturing company can receive many customer orders at once. When an order is received, the OrderProcessing business process allocates a unique order number, updates the Customer service and invokes the Credit service. The process does not continue until the Credit service notifies it that the customer's details are valid, and this can take some time. Since multiple instances of the OrderProcessing process can exist at runtime, how can a specific instance be selected when the Credit service is ready to send notification?

Question19: As part of an SOA initiative, a utility company is re-writing a 2-tier call center application used for reporting power outages. Customers call in to report power outages and in some cases ask to be notified when the problem is fixed. The call center application is tightly coupled with a vendordeveloped power management application which dispatches workers for repairs. The current call center application is difficult to maintain since it implements a very large and complex framework to manage the calls and the relationship with the power management system. Which design approach should the SOA Designer use?

How does the SOA Designer rationalize this choice?

Question48: A mobile phone company is losing money on the process for deactivating a phone when it is reported stolen or lost due to lag time between notification and deactivation. In the current SOA solution, call center staff disable the phone via a portlet that invokes a deactivation service which calls a mainframe application.
The mainframe application notifies the telecom provider to deactivate the phone. What is a likely cause of the issue and which aspect of the solution makes the problem worse?

Question49: A new business process is being written that will call a number of new or existing Web services. As part of the SOA quality management process, which activity is the most appropriate?

Question50: A large corporation would like to utilize an SOA reference architecture for its various solutions. The need is for a flexible layered SOA model that can be used in a variety of application-related situations. The SOA Architect is assigned to find such a model.

Question52: A retail company is faced with the challenge of quickly introducing new products involving components from multiple lines-of-business. How can adopting SOA help this company meet this challenge?

Question53: A manufacturing company has completed an SOA proof of concept using ten services to integrate several existing internal applications. The solution includes failover for the various services. During a power outage, three of the five application servers were non-operational. While the system never totally failed, IT operations notified the business analyst of the failure and recovery. In looking at the performance measurement metric trends during the outage, the business analyst noticed that one of the ten services was negatively impacted and could have violated potential Service Level Agreements (SLAs).
How should the SOA Designer address this architectural issue(s) during assessment and analysis for the final production system?

Question54: A manufacturing company can receive many customer orders at once. When an order is received, the OrderProcessing business process allocates a unique order number, updates the Customer service and invokes the Credit service. The process does not continue until the Credit service notifies it that the customer's details are valid, and this can take some time. Since multiple instances of the OrderProcessing process can exist at runtime, how can a specific instance be selected when the Credit service is ready to send notification?

Question55: At an organization, some standards-based technologies have been adopted around a J2EE application server. There is now a need to provide multi-channel access to existing service providers. Which product should be used for service connectivity in this design?

The medical practice is implementing an SOA assessment and analysis. Which approach will most likely resolve this situation?

Question57: A company has started an ambitious SOA project as part of an enterprise modernization initiative. The SOA Designer has determined that their mainframe-based portfolio is a tightly coupled set of applications owned by different IT organizations. In addition, the SOA executive sponsor is concerned that their mainframe portfolio and skill base will make the transition to SOA difficult. What should the SOA Designer do?

Question58: Service enabling a mainframe application can be non-invasive or invasive. Which scenario is a justification for invasive service enablement?

Question59: A photo printing business has a central headquarters and approximately 5000 store fronts. They offer an existing service which allows customers to physically enter a store and print their pictures. The latest project involves enabling a website where customers can upload photos to print at the store location of their choice for pickup. The plan is to use the existing service hosted at each store front to do the printing.
Which patterns should be considered when designing this solution?

Question60: It has been determined that an application running on a mainframe needs to be service-enabled to allow it to be invoked asynchronously via an Enterprise Service Bus (ESB). The application interface is already capable of accepting WebSphere MQ messages, and the SOA designer does not wish to modify the current application code. What is an appropriate method of service-enabling the application that would also offer a high level of reuse of the resulting service in a business process?

Question61: A retail company is faced with the challenge of quickly introducing new products involving components from multiple lines-of-business. How can adopting SOA help this company meet this challenge?
