Example Questions

I built a service-oriented solution a year ago comprised of 3 services. I've just been told that the business process automated by the solution is going to be replaced by a new business process that introduces some changes to how the business process logic needs to be automated. What should I do? Project Team Alpha delivers Service A for Solution 1. Project Team Beta delivers Service B for Solution 2. Some time later, Project Team Omega wants to reuse Service A and Service B for its new Solution 3. How would Services A and B need to have been designed in order for Project Team Omega to successfully reuse these services without having to resort to a major integration project? Which of the following statements makes sense? Which of the following statements is false? There can be different types or scopes of service-oriented architecture. For example, you could define separate architecture specifications for a service and a service inventory. Solution logic is classified as "service-oriented" after: Two common, yet opposing SOA delivery approaches are: Project Team A delivers Domain Service Inventory A with 20 services. If Project Team B delivers Domain Service Inventory B with 50 services, how many services are in the Enterprise Service Inventory? Which of the following is an expected result of successfully adopting SOA? Complete the following statement with the correct text: "The objective of organizational agility is to dramatically reduce the time and effort required to fulfill new or changed business requirements... Service-orientation supports the realization of the strategic goals associated with service-oriented computing. There are two basic types of service-oriented solution logic: __________ and __________. Which of the following statements is true? When planning a transition toward SOA, we are usually required to balance the __________ goals with the __________ requirements. Which of the following is not the result of achieving the strategic goal of Reduced IT Burden? The ROI (return on investment) potential of services is increased by: Which of the following is a recommended or common part of a service-oriented enterprise? When following the distinct lifecycle phases of an SOA delivery project you are: What is the minimum number of domain service inventories you need in order to create a single enterprise service inventory? When designing service-oriented architectures, it is important to take the strategic goal of Increased Vendor Diversity Options into account, because this goal: When you establish a federated service layer, you end up creating: Service A invokes ServiceB. Service B invokes ServiceC. Service C invokes both Service D and Service A __________ can be part of a/an __________ which can be assembled from __________ within a/an __________. Service-oriented analysis and service-oriented design are typical phases of an SOA delivery lifecycle. Service Composition A is comprised of 4 services. Service Composition B is comprised of 6 services. Because both service compositions are comprised of services from the same service inventory, the service inventory will have a total of how many services? To qualify as a service composition, at least __________ participating services need to be present. Otherwise, the service interaction only represents a point-to-point exchange. In order to achieve __________ we have traditionally required __________ projects. With service- orientation, we aim to establish an intrinsic level of __________ within each service so as to reduce the need for __________ effort. A fundamental means of achieving business and technology alignment in support of service-oriented computing is: A software program that invokes and interacts with a service is referred to as a: The use of __________ services tends to __________ the size of service compositions. Which of the following statements accurately describes the strategic benefit of Increased Federation? __________ and __________ are used to classify and organize services within a service inventory. Service-oriented computing aims to increase an organization's responsiveness by allowing it to adapt to change more efficiently and effectively. This is known as: A service inventory is considered to have normalized services when: The ability of one service to __________ another service forms the basis of service __________. Which of the following is not a benefit of maintaining a vendor-neutral and business-driven context for a service-oriented architecture? Services are ideally designed to be: The Universal SOA Commission (USOAC) has been standardizing the service-oriented architectural model since 1998. Their role is to regulate the marketplace to ensure that all usages of the "SOA" acronym for branding purposes are legitimate. They enforce this via product assessment and certification, a process that all of the major software vendors follow to obtain official USOAC certification. Service Autonomy, Service Statelessness, and Service Loose Coupling are examples of: Which of the following statements does not make sense? The distinct ownership and governance requirements introduced by agnostic services can introduce the need for more __________ staff and less __________ staff. By applying a __________ strategic scope to the technology architecture, it can be kept in constant synch with how the business evolves over time. An IT enterprise proceeds with an SOA initiative that is based on the creation of a single enterprise service inventory. However, conflicts arise when different IT departments disagree on who will own the services and how they will be governed. Which of the following alternative approaches could be chosen to address these conflicts? "A primary focus of service modeling is the encapsulation and abstraction of business logic in support of defining business service candidates." What is wrong with this statement? What is wrong with this statement: "We delivered two services last year. Even though each service was delivered by a separate project team in a different location and at a different time, I am confident that the services will be reasonably interoperable because each project team was asked to use the same design standards." When enterprise-wide standardization is unattainable, multiple domain service inventories may need to be created instead of: Four IT managers from different organizations have chosen to adopt SO Service metadata can be centrally registered within a __________ for discoverability purposes. Service composition is important to the success of SOA initiatives because: Service-oriented architecture must be designed to be both integration-centric and silo-based.
