Demo Questions
Question 1
When applying the Messaging Metadata pattern, it is customary to place business document data in the message header and supplementary messaging metadata in the message body.
- True
- False
Correct answer: B
Question 2
The Messaging Metadata pattern requires a messaging framework that supports the processing of messages with headers or properties.
- True
- False
Correct answer: A
Question 3
Which of the following statements is false?
- Widespread use of the Messaging Metadata pattern can be seen in the emergence of many WS-* extensions that define industry standard SOAP header blocks that carry metadata.
- Messaging frameworks and technologies need to provide support for the reading and writing of message headers or properties in order to fully support the application of the Messaging Metadata pattern.
- The Messaging Metadata pattern is not applicable to situations where the message sender and receiver need to participate in stateful or conversational message exchanges.
- The Messaging Metadata pattern can support the application of patterns such as Intermediate Routing by supplementing messages with activity-specific metadata.
Correct answer: C
Question 4
A service agent has a technical contract that allows it to be explicitly invoked by service consumer programs.
- True
- False
Correct answer: B
Question 5
Which of the following functions would not be suitable for a typical service agent?
- event logging
- message routing
- complex Web service composition
- error logging
Correct answer: C
Question 6
The use of service agents will affect the design of service compositions as follows:
- it will tend to increase the number of required services
- it will tend to decrease the number of required services
- it will tend to increase the number of required service compositions
- it will tend to decrease the number of required service compositions
Correct answer: B
Question 7
Which of the following statements is true?
- The overuse of service agents can lead to dependencies on proprietary vendor platforms.
- The use of service agents is limited to the service architecture.
- Service agents are common in orchestration environments but not within enterprise service bus environments.
- None of these statements are true.
Correct answer: A
Question 8
Governance can become an issue with service agents because:
- You will need to determine who will own and maintain the service agents.
- Changes to a single service agent can impact multiple services throughout a service inventory.
- Service agents need to be versioned, just like services.
- All of the above.
Correct answer: D
Question 9
Which of the following patterns may also require the application of the Service Agent pattern?
- Reliable Messaging
- Asynchronous Queuing
- Intermediate Routing
- Policy Centralization
Correct answer: ABCD
Question 10
Which statement regarding intermediate routing is true?
- The application of the Intermediate Routing pattern is suitable for handling message routing requirements that are dynamic in nature and difficult to anticipate in advance.
- The application of the Intermediate Routing pattern is suitable for handling pre-determined message paths with fixed routing requirements that cannot be changed at runtime.
- The application of the Intermediate Routing pattern tends to improve runtime performance when compared to an approach whereby routing logic is embedded within individual services.
- None of these statements are true.
Correct answer: A
