WSO2 Certified Enterprise Integrator 6 Developer (6.5 version) - Enterprise-Integrator-6-Developer Exam Practice Test

A. Performance issues due to the overhead added to the communication by message systems.

B. Operation is disconnected from networks. Data is synchronized when network connection is available.

C. Messaging systems introduce additional programming complexity.

D. Messaging systems do not guarantee when the message will be delivered, which cancause sequencing issues.

A. Toinvoke a fault sequence for handling errors, you need to throw an AxisException from the Class mediator whenever required.

B. Both statement a and b are incorrect.

C. To facilitate better debugging, you need to set ERROR_CODE, ERROR_MESSAGE, and ERROR_DETAIL properties inside the Class mediator.

D. If you throw any exception that is a subclass of Java's Exception class, the fault sequence will be triggered.

A. The Exception mediator can be used to customize error messages that are send back to the client.

B. A fault sequence is a collection of mediators just like any other sequence, and it can be associated with another sequence or a proxy service.

C. Within the fault sequence, you can access error details using the EXCEPTION_DETAIL property.

D. It is mandatory to associate each sequence and proxy service with a fault sequence.

A. Write a Synapse handler.

B. Write a custom messagebuilder and formatter.

C. Write a Class mediator.

D. Use the Script mediator.

A. Any JMS consumer application cannot consume messages from a given store. Only message processors can consume messages in a JMS message store.

B. Users have the option to create a custom message store with their own message store implementation.

C. Both a and b are correct.

D. The ESB profile supports the store-and-forward pattern but not guaranteed delivery.

A. Message headers are altered but not the content.

B. Message content is altered during mediation.

C. The ESB profile may read the message content depending on the mediators that you have configured.

D. During pass-throughmessaging, the mediation logic is completely bypassed.

A. To handle a messaging structure in the ESB profile.

B. To support a transport protocol not available out-of-the-box in the ESB profile.

C. To handle a content type that is not supported by the ESB profile.

D. To process an incoming message structure that is not supported by existing constructs in the ESB, convert it into the ESB profile's canonical message format, and convert the outgoing message from the canonical format to the expected message structure.

A. Use the Switch mediator.

B. None of these approaches would implement this scenario.

C. Use the Script mediator and implement the above routing logic.

D. Write a custom Class mediator and implement the custom routing logic inside that mediator.

A. Pipes and Filters

B. Message Translator

C. . Message Channels

D. Composed Msg. Processor
