  2. Acme, Inc. is conducting an SOA transformation program. The program has been accepted by IT senior management.

The technical team has a good architectural understanding of the design considerations and infrastructure needed to support the target services. Acme has not yet constructed or harvested any services. What should Acme focus on next?
  A. Focus on developing the initial shared services reference architecture
  B. Services should be classified and categorized by their relative risk and business priority
  C. A cost model should be constructed to evaluate best sequencing of services
  D. Initial common services such as authentication, exception handling, and logging should be harvested and/or constructed
  Answer: D

  3. A services schema needs a field added. This will be an incompatible change to the service interface. The service interface and implementation will be updated to handle and store this field. The new service version will be deployed to a new URL endpoint. How should this change be handled?
  A. All dependents should move to the new URL
  B. All dependents can continue use the existing URL; maintain parallel implementations at the new and existing URL.
  C. An intermediary should be provided to adapt the interface from the existing URL to the new URL
  D. An intermediary should be provided to adapt the interface from the new URL to the existing URL
  Answer: C

  5. Johnston Marks, a regional bank, are looking to use SOA as a way to improve their product development processes to support their growing business. Their primary problem is in dealing with the volume and diversity of information required in developing a product. Currently, usage feedback, marketing research information, and industry intelligence is gathered through a variety of legacy systems, spreadsheets, desktop databases, letter mail, and FAX. Which two goals are most appropriate for leveraging SOA in this process improvement exercise?
  A. Reduce variance and ensure repeatability of the process
  B. Eliminate some sources of information through services
  C. Provide more consistent and managed interfaces to the various information sources
  D. Enable the incorporation of newer and higher volume sources into the process
  Answer: CD

  6. Best Tech, inc. is a national retailer of consumer electronic goods. Their stores have been dealing with supply problems. Best Techs central distribution department allocates goods to stores based on weekly forecasts calculated by their inventory system. These forecasts are based on monthly batch files sent from the stores that contain sales history. The marketing department sometimes runs flash promotions which causes a run on a particular product. The forecasters usually account for this, but they dont account for complementary products, or products that may be nearby in the store layout that become whim purchases. As such, Best Tech stores are often out of stock on many popular items. Other times, Best Tech stores and regional warehouses are flooded with inventory that they dont need.
  While there are several solutions to this problem, what would be the optimal solution for BestTech to handle sales of complementary products, considering SOA best practices?
  A. Service enable the forecast feeds so they can be sent on a more frequent basis.
  B. Service-enable point of sale and inventory: All sales from the point of sale system should invoke a shared business service that logs the sale, so the forecasters have up-to-the-second planning information
  C. Service-enable a pull supply chain: All sales from the point of sale system should invoke a shared business service that immediately orders a new part from the warehouse. This in turn invokes a service at the regional distributor, which then invokes a service at the supplier.
  D. Service-enable the local store and regional warehouse inventory systems, so the planning department can, in real time, request inventory status from several stores at once to gain a more accurate single view to drive forecasts.
  Answer: C

Furthermore, these initiatives all seem to be developing separate, and overlapping, customer data stores. Which of the SOA domains could most use improving (choose two)?

  13. Langham Rudolph, a large industrial manufacturing firm, has a procurement department that serves the purchasing needs for over 14 manufacturing sites. These sites were acquired over a period of time, and operate with disparate legacy systems that serve a variety of requirements beyond just purchasing. It takes an average of 20 minutes to log off one site and log on to another site, and each site maintains its own set of purchasing rules and part numbering system. Thus, purchasers will typically process all requirements for a single site before moving onto the next one this will often take up to a whole day. This system unfortunately did not handle priorities well customer purchasing requirements could be held up as much as 14 days if it was at the end of the list.
  How should this problem be solved, balancing effectiveness and time to implement? Choose two of the following:
  A. The purchasing department should be sent a list of orders to expedite and dedicate one or more resources to spend the extra time switching between systems and expediting.
  B. Shared business services should be written to replace the legacy systems for all purchasing functions. This will provide a unified part numbering format and purchasing rules.
  C. A composite application should be written to pre-login and communicate across all legacy systems, automatically translating between part numbers and rules, but re-using each legacy systems existing local rule base.
  D. A presentation service should be written to sort orders by priority and part type.
  Answer: CD

  14. An order entry service is deployed on a .NET based cluster, callable through SOAP over HTTP, with an expected response time of 1.5 seconds, and guaranteed exactly once message delivery using WS-ReliableMessaging.

  What physical part of the service is changing? Make no assumptions other than the information given.
  A. The service URL
  B. The service WSDL
  C. The service transport
  Answer: A

  15. Serendipity Securities, Inc. has two major business objectives:
  1. Ensure consistent customer information and service capabilities across all product lines and all customer channels (interactive voice response, call centre, and website)
  2. Maintain business unit autonomy so new products and/or services can be introduced in a timely fashion.
  What is the likelihood of achieving all the objectives through an SOA program?
  A. Both objectives can be met; both agility and consistency are complementary.
  B. It is unlikely the objectives can be met because agility and consistency are contradictory.
  C. There is a tradeoff between agility and consistency in dealing with product information, and some compromise must be made between the business units
