IBM C2160-667 Online Questions & Answers

• Question 1:

  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?

  A. Recommend a monitoring solution to identify the architectural cause of the service failure caused by the outage.
  B. Ensure sufficient capacity exists in the new system for failover to meet SLAs.
  C. Recommend continuous monitoring of SLAs and balance failover across all services.
  D. Adopt an SLA threshold for early identification of potential SLA violations and alert on those thresholds.
  C. Recommend continuous monitoring of SLAs and balance failover across all services.

• Question 2:

  The Chief Architect at a large company requested an audit of SOA projects to ensure no design aspects had been overlooked. A key finding was that management of services was not present in any of the designs reviewed. What should an SOA Designer suggest?

  A. A management viewpoint should be incorporated into the architecture being used as this should be included in any SOA foundation.
  B. Existing management functions should have a one time review to identify where services should be added to support current and future SOA projects.
  C. Existing management functions should be extended to accommodate services and integration of the services into the management functions as a new type of resource.
  D. No changes in design are necessary since the principle of separation of concerns dictates that management functions are best designed after services have been implemented.
  A. A management viewpoint should be incorporated into the architecture being used as this should be included in any SOA foundation.

• Question 3:

  A telecom company has a Service Level Agreement (SLA) that requires Customer Service Representatives (CSRs) to respond to customer inquiries within 10 minutes. Often the CSR has to access nine independent legacy applications to respond to customers' inquiries. CSRs are consistently exceeding the 10 minute SLA. What is the quickest way to satisfy the SLA using an interaction and collaboration scenario based on an SOA approach?

  A. Write another application that acts as the interface to the other applications.
  B. Wrap the legacy applications into services and aggregate these services as UI views.
  C. Implement Information Services to build a data warehouse and aggregate customer information into views.
  D. Implement data federation and integrate the legacy applications on the glass using portlets.
  B. Wrap the legacy applications into services and aggregate these services as UI views.

• Question 4:

  A company wishes to create a service from a legacy application that uses a simple but proprietary data format over a TCP/IP connection. What is an advantage of creating an adapter or wrapper to enable this application as a service?

  A. The legacy application will be made more highly available through the use of an adapter.
  B. The use of standards in the adapter will enable the legacy application to be used within a business process more easily.
  C. A wrapper will automatically generate valid XML datatypes to interoperate with all of the datatypes used by the legacy application.
  D. A wrapper can be added to the legacy application to control the Quality of Service (QoS).
  B. The use of standards in the adapter will enable the legacy application to be used within a business process more easily.

• Question 5:

  An engineering services company is being asked by its customers to provide solutions that cross Line of Business (LOB) areas. Each LOB is independent and is measured on its own profitability. The Chief Operating Officer plans to make

  some organizational changes.

  How could SOA enable this business transformation?

  A. Provide an abstraction layer for each LOB application that will allow flexible composition of services tailored to each LOB business model. Create an Enterprise Service Bus (ESB) that supports integration of systems across the LOBs for reuse.
  B. Provide shared business services by migrating to a commercial Enterprise Resource Planning (ERP) system that can be service-enabled for access through an enterprise portal or from existing individual LOB applications.
  C. Implement information as a service to consolidate data models and sharing across LOBs. Support governance of the service portfolio at an enterprise level.
  D. Create an architecture board for each LOB to introduce SOA processes and drive service identification, goal modeling and business process re-engineering in support of mapping services to business capabilities.
  C. Implement information as a service to consolidate data models and sharing across LOBs. Support governance of the service portfolio at an enterprise level.

• Question 6:

  A government department has been directed to make sure that its agencies can share data so they can handle crises effectively. Laboring under a prior directive to migrate to SOA, the Chief Architect is looking for the best way to incorporate

  this latest directive.

  What should the SOA Designer recommend?

  A. The various agency databases should be federated and information services implemented. The data transformation capabilities are included in data federation.
  B. New data replication processes should be introduced so that information within agency databases can be shared whenever needed. Data transformation should be incorporated within the replication processes where there is a mismatch.
  C. Enterprise Service Bus (ESB) message transformations should be used to transform exchanged data based on agency standard data models. Existing messages should be converted into XML so that SOAappliances can use XSLT to convert the messages at high speed.
  D. Business experts and IT data modelers should develop an enterprise level standard data model. Each agency can then define how its data can be converted into the standard. Once done, Extract/Transform/ Load ETL tooling can be used for large scale cleansing of the existing databases and transforming it into the new standard.
  A. The various agency databases should be federated and information services implemented. The data transformation capabilities are included in data federation.

• Question 7:

  A midsize city is experiencing rapid growth that requires extensive changes in city land use regulations. Under this pressure, many land use disputes are getting caught in endless inter- departmental exchanges to complete data collection using a variety of completion criteria. This is angering both citizens and land developers. Which approach to SOA is likely to have the greatest impact?

  A. Apply governance policies and procedures to control inter-departmental exchanges.
  B. Align the departments with a common end-to-end process with shared business services.
  C. Align the departments with a common data model and data access services to avoid confusion and duplication.
  D. Create citizens portals to provide a mechanism for citizens to more easily monitor and manage their role in the process.
  B. Align the departments with a common end-to-end process with shared business services.

• Question 8:

  An SOA Designer for a bank is identifying candidate services for realization. They have determined that the central office and the regional office share the same process, "Open Account", which includes three steps "Account Data Collection", "Account Verification", and "Account Activation". There is an existing customer CICS application for "Account Information Input", "Account Setup", and "Account Inquiry" functionality and an existing SAP system for General Ledger which includes a "Create Account" function. Which are most likely candidates as services in this scenario?

  A. Account Data Collection, Account Inquiry, Create Account
  B. Account Setup, Account Information Input, Account Activation
  C. Account Setup, Account Inquiry, Create Account
  D. Account Data Collection, Account Verification, Account Activation
  D. Account Data Collection, Account Verification, Account Activation

• Question 9:

  How can a designer most effectively integrate components developed in various technologies at different companies into a composite application within an SOA?

  A. Through careful coordination to ensure compatible interfaces
  B. Through the use of industry standards such as SOAP over HTTPS
  C. By placing the components in a service repository which will mediate the differences in their interfaces
  D. By providing code mediation and transformation functions through a business process modeling effort
  B. Through the use of industry standards such as SOAP over HTTPS

• Question 10:

  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?

  A. System capacity and peaks in the demand on this process
  B. Throughput and the time of day that people most commonly report mobile phone theft
  C. System reliability and the skills of the administrative staff involved
