Question 1

Which of the following is a common challenge imposed by the adoption of service-orientation? Select the correct answer.

Accepted Answer

Service-orientation introduces the need for design standards to ensure consistency and interoperability across services, which can be challenging to enforce.

Question 2

Fill in the blank for the following definition for the Service Loose Coupling design principle: "Service contracts impose low __________________ requirements and are themselves decoupled from their surrounding environment." Select the correct answer.

Accepted Answer

Service Loose Coupling design principle emphasizes minimizing dependencies between services and their consumers, hence "consumer coupling" is the correct term to fill in the blank.

Question 3

A composition member is a service that participates in a service composition by being composed by another service. Select the correct answer.

Accepted Answer

A composition member is indeed a service that is part of a larger service composition, meaning it is integrated or composed with other services to form a composite service.

Question 4

A(n) __________________ in the extent to which a service needs to share resources with other parts of the IT enterprise will result in a(n) __________________ of the service's overall __________________. Select the correct answer.

Accepted Answer

A decrease in the need to share resources with other parts of the IT enterprise results in an increase in the service's overall autonomy.

Question 5

The service-orientation principle primarily concerned with ensuring the runtime behavioral predictability of a service is: Select the correct answer.

Accepted Answer

There is no specific service-orientation principle called "Service Prediction" or any principle that directly ensures runtime behavioral predictability. The options provided do not accurately describe a principle focused on predictability.

Question 6

When referring to the Service Discoverability principle, the quality of interpretability refers to a service's ability to be effectively discovered at runtime by service consumer programs designed to carry out dynamic runtime discovery. Select the correct answer.

Accepted Answer

The quality of interpretability in the Service Discoverability principle refers to how easily a service's capabilities and usage can be understood by humans or programs, not specifically to its ability to be discovered at runtime.

Question 7

By providing __________________ awareness of reusable services available for composition, the __________________ principle can greatly benefit the design of service-oriented solutions. Select the correct answer.

Accepted Answer

None of the provided options correctly describe the principle of Service Discoverability, which is about increasing awareness of reusable services.

Question 8

The Service Reusability principle can __________________ demands on infrastructure because services that are reused will typically have __________________ security, performance, and reliability requirements. Select the correct answer.

Accepted Answer

The answer of The Service Reusability principle can __________________ demands...

Question 9

Which of the following characteristics directly supports or enables behavioral predictability within services? Select the correct answer.

Accepted Answer

Reliability ensures consistent results and performance, which directly supports behavioral predictability within services.

Question 10

The __________________ principle can be applied together with the __________________ principle and the __________________ principle to establish a service contract that conforms to design standards, does not impose negative dependencies upon service consumers, and does not reveal unnecessary information about its underlying implementation. Select the correct answer.

Accepted Answer

The answer of The __________________ principle can be applied together...

Question 11

Fill in the blank for the following definition of the Service Abstraction design principle: "__________________ only contain essential information and information about services is limited to what is published in service contracts." Select the correct answer.

Accepted Answer

Service contracts only contain essential information and information about services is limited to what is published in service contracts, aligning with the Service Abstraction design principle.

Question 12

A service is sometimes referred to as an enterprise resource because: Select the correct answer.

Accepted Answer

A service is considered an enterprise resource because it can be utilized by multiple parts of the enterprise, providing a shared functionality or capability.

Question 13

Which of the following statements correctly explains the difference between the Service Reusability and Service Composability principles? Select the correct answer.

Accepted Answer

Service Reusability focuses on designing services that can be reused in different contexts, while Service Composability focuses on designing services that can be easily combined with other services to form composite applications.

Question 14

A service-oriented solution can be comprised of which of the following core architectural elements? Select the correct answer.

Accepted Answer

The answer of A service-oriented solution can be comprised of...

Question 15

The enforcement of service contract design standards is required to effectively apply the Standardized Service Contract principle. Select the correct answer.

Accepted Answer

The Standardized Service Contract principle relies on consistent design standards to ensure interoperability and reusability across different services.

Question 16

A composition initiator is a variation of the composition controller role that represents nested composition logic. Select the correct answer.

Accepted Answer

The answer of A composition initiator is a variation of...

Question 17

Which of the following statements is true? SELECT ALL THAT APPLY

Accepted Answer

The Service Composability principle is related to Service Reusability as composition involves reusing services. It emphasizes designing services for effective participation in multiple compositions and prepares them for both immediate and future compositions. The concept itself is not revolutionary, as aggregation in distributed computing is not new.

Question 18

Fill in the blank for the following definition of the Service Reusability design principle: "Services contain and express __________________ logic and can be positioned as reusable enterprise resources." Select the correct answer.

Accepted Answer

The term "agnostic" in this context refers to logic that is not specific to a particular application or business process, making it reusable across different contexts and services.

Question 19

The __________________ principle encourages services within the boundary of a specific service inventory to share messages based on the same data models. This practice directly supports the __________________ principle, which is concerned with designing services so that they can be effectively and repeatedly aggregated into different solutions. Select the correct answer.

Accepted Answer

The Standardized Service Contract principle encourages the use of consistent data models for message sharing, supporting the Service Composability principle, which focuses on designing services for effective aggregation.

Question 20

The Service Loose Coupling principle advocates which of the following coupling types? Select the correct answer.

Accepted Answer

The answer of The Service Loose Coupling principle advocates which...
