1. What is content-awareness in a mediator?

The method"isContentAware" in the mediator specifies whether the mediator requires the message to be built in order to perform the mediator action.

If the mediator is content-unaware, it will always build the message.

It is the mediator's ability to identify the messaging format and select matching message builders and formatters.

All of the above.

2. Which statement about deploying a newSynapse handler is correct?

To engage the deployed Synapse handler, you need to add a new configuration to the <handlers> section to the <EI_HOME>/conf/synapse-handlers.xml file.

All of the above.

If you have developed your handler as a non-OSGI JAR file, copy it to the directory.

If you have developed your handler as an OSGI bundle, copy it to the /dropins directory.

3. Which statement is TRUE about Java Message Service (JMS) message stores in the context of the ESB profile?

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

Both a and b are correct.

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

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

4. Which statement is FALSE about WS02 transport-level security?

WS02 EI can support TLS 1, TLS 1.1, and TLS 1.2 with JDK 1.7

You must enable HTTPS transport configuration in aixs2.xml in order to usetransport-level security.

The HTTPS transport supports SSL tunneling.

Transport-level security secures the messages in the wire.

5. In the proxy service, it is necessary to call one of the several back-end services depending on the format of the message. Forinstance, the incoming message to the proxy service might have a property called "company". If company == 'IBM', we need to call the IBM service, and if company == 'Google', we need to call the Google service.

To implement this scenario, what would be thebest option available in the ESB profile?

None of these approaches would implement this scenario.

Use the Switch mediator.

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

Use the Script mediator and implement the above routing logic.

6. Which is a valid extension point for the ESB profile of WS02 EI?

Custom Synapse Handler by extending AbstractSynapseHandler

Custom transport by implementing org.apache.axis2.transport.base.AbstractTransportSender and org.apache.axis2.transport.base.AbstractTransportListener interfaces

All of the above

Custom class mediator byextending AbstractMediator.

7. Which of the following EIP patterns does NOT alter the message content?

Wire-Tap

Message Translator

Content-Enricher

Splitter

8. Which statement about the ESB profile message store/message processor functionality is FALSE?

Using message store/message processor constructs, guaranteed messagedelivery can be implemented.

Using message store/message processor constructs, the dead letter channel pattern can be implemented.

Using message store/message processor constructs, in-order delivery of messages cannot be implemented.

Using message store/message processor constructs, message throttling can be implemented.

9. Select the appropriate Enterprise Integration Pattern (EIP) that can be used to remove unimportant data items from messages and leave only the important ones.

Message Filter

Dynamic Router

Content Filter

Composed Msg. Processor

10. Which statement is FALSE about message entry points?

A proxy service receives messages that aresent to specific endpoint.

APIs can only accept JSON or XML messages but not SOAP messages.

An inbound endpoint injects a message directly from the transport layer to the mediation layer, without going through the Axis engine.

A task injects a message into the ESB profile at a scheduled interval.

11. Select the appropriate Enterprise Integration Pattern (EIP) that can be used to combine the results of individual but related messages so that they can be processes as a whole.

Envelope Wrapper

Process Manager

Aggregator

Composed Msg. Processor

12. What is the best option to run custom Java code in a periodical manner within WS02 ESB?

Write a custom task with the Javalogic and configure it to run periodically.

Option b and c are correct.

Write a Class mediator with the Java logic, create a proxy service that uses that mediator, and send messages using an external client periodically.

13. Suppose your enterprise application has a requirementto execute a large number of RDBMS data interactions.

Which of the following is the best option when designing this situation using the WS02 platform?

Use WS02 EI with data services for database operations

DBLookup mediator

Store mediator

DBReport mediator

14. What should you enter for the cacheld configuration element that resides inside the remotelnstance configuration section of the <EI_HOME>/conf/registry.xml file?

<remoteInstance url="https://localhost:9443/registryn>

<id>instaceid</id>

<dbConfigx/dbConfig>

< readonly >true</readOnly>

<enableCache>true</enableCache>

<registryRoot>/</registryRoot>

<cacheldx/cacheld>

</remoteInstance>

The SHA 256 hash of the JDBC connection URL of the registry database.

The value you entered for the element.

The SHA 255 hash of the value you gave to the element.

The JDBC connection URL of the registry database.

15. Which statement is FALSE about message builders and formatters?

When a message comes into the ESBprofile, an appropriate message builder converts the message's raw payload data into XM

Axis2 framework can be used to implement custom message builders and formatters.

When sending a message out from the ESB profile, a message builder is used toconvert XML back into its original format.

When sending a message out from the ESB profile, a message formatters is used to convert XML back into its original format.

16. Which statement is true about outbound endpoints?

Outbound endpoints are mandatory for any integration scenario.

They operate in the same way as inbound endpoints.

When you use message stores, you have to specify the address as an outbound endpoint.

Outbound endpoints can have flags to translate the message.

17. You have created a custom ESB task that you want to run every 30 seconds for 50 times.

Select the CORRECT task configuration you can use for this purpose.

All three configurations are incorrect.

18. If you are running two or more ESB profile servers on the same physical machine, it is necessary to offset ports. Select the correct statement that describes how to offset ports in the ESB profile.

Go to <EI_HOME>/conf/axis2, open the axis2.xml file, and add the following top-level configuration: <Ports><Offset>2</Offsetx/Ports>

Both statement 1 and 2 are correct.

Both statement 1 and 2 are incorrect.

Go to <EI_HOME>/conf, open the carbon.xml file, locate the following configuration and increase the Offset ^ value. <Ports><Offset></Offsetx/Ports>

19. Select the CORRECT statement about deploying custom mediator artifacts.

If itis a class mediator, you can put that JAR file in the <EI_HOME>/lib directory.

If you have developed your custom mediator as a regular non-OSGI JAR, you have to put it in the <EI_HOME>/extensions directory.

All of the above.

If you have developedyour custom mediator as an OSGI bundle, you have to put it in the <EI_HOME>/dropins directory.

20. 1.Select theINCORRECT statement regarding ESB connectors.

Integration is much faster than using sequences and proxy services.

Connectors cannot be directly added and removed to the runtime, so after deploying them you have to restart the servers.

No extensiveknowledge of the source system is required to use ESB connectors.

150+ connectors are available, and WS02 is continuously adding more to the connector collection.

21. Identify the INCORRECT statement with respect to endpointtimeout:

For all endpoint timeout values. Endpoint Timeout >= http.socket.timeout The following is a correct endpoint definition with a timeout value and a response action: <endpoint> <addressurl="http://localhost:8281/services/SimpleStockQuoteService"> <timeout>

<duration>120000</duration> <responseAction>fault</responseAction> </timeout> </address> </endpoint>

It is possible to define a response Action to be taken in case of an endpoint timeout within the endpoint definition.

Endpoint timeout specifies the timeout duration for an endpoint and allows different timeouts to be specified for different endpoint definitions.
