When enterprise-wide standardization is unattainable, multiple domain service inventories may need to be created instead of:

• A.multiple enterprise service registries
• B.a single enterprise service inventory
• C.a single enterprise service registry
• D.multiple enterprise service inventories

Which of the following statements is true?

• A."Contract first" design is important to SOA because it makes you think about service contract design options at the same time that you are building the underlying service logic.
• B."Contract first" design is an unproven design technique that is not commonly employed when delivering service-oriented solutions and is therefore not considered important to SOA.
• C."Contract first" design is important to SOA because without a contract, services cannot be invoked. However, there is no preference as to when, during the service delivery lifecycle, the contract should be designed or established.
• D."Contract first" design is important to SOA because it forces you to establish standardized service contracts prior to the development of the underlying service logic.

Service-orientation supports the realization of the strategic goals associated with service-oriented computing.

• A.True
• B.False

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.Because SOA projects absolutely require enterprise-wide standardization and further demand the creation of an enterprise service inventory, the IT managers have no choice than to cancel the project.
• B.It is decided to proceed with the creation of multiple domain service inventories. This allows collections of services to be independently governed by different owners, while still enabling the IT enterprise as a whole to transition toward SOA.
• C.The top-down approach is chosen. This allows services to be modeled subsequent to their design, thereby enabling each service to be governed by multiple owners.
• D.The established "contract last" approach is chosen, allowing different IT managers to focus on contract-related governance issues after the services are deployed and in use.

The goals of service-oriented computing are focused on tactical (short-term) benefits, as opposed to strategic (long-term) benefits. Select the correct answer.

• A.True
• B.False
