Question 1

Which statement regarding the AppDomain in a .NETCompute Node is true?

ACode sharing an AppDomain can share state.

BThere is no way to share data among different AppDomains.

CA domain neutral assembly can be unloaded without unloading the whole AppDomain.

DWhen a .NET assembly code is changed and swapped, the message flow must be stopped and restarted to pick up the change.

Answer : A

Question 2

When using the MQTTPublish Node to route messages, how can it be determined if the message was published successfully?

ACheck the Boolean in LocalEnvironment.Destination.MQTT.Output.retained in a node wired to the Out terminal of the MQTTPublish Node.

BCheck the Boolean in LocalEnvironment.WrittenDestination.MQTT.Output.retained in a node wired to the Out terminal of the MQTTPublish Node.

CCheck the Boolean in LocalEnvironment.Destination.MQTT.DeliveryToken.isComplete in a node wired to the Out terminal of the MQTTPublish Node.

DCheck the Boolean in LocalEnvironment. WrittenDestination.MQTT.DeliveryToken.isComplete in a node wired to the Out terminal of the MQTTPublish Node.

Answer : D

Question 3

How can end-to-end transactionality be achieved in a SOAP message flow?

ABy selecting transaction Yes for JMS binding.

BBy having the SOAP call interact with a database transaction.

CBy having persistent sessions with SOAP over HTTP binding.

DInteractions between SOAP operations must implement SOAP fault messages.

Answer : D

Question 4

Which node can be used to capture failures for a sequence of nodes?

ATrace Node

BCollector Node

CTryCatch Node

DPassthrough Node

Answer : C

If you do not wire a Failure terminal, a failure in the node is converted into an exception which is thrown from the node.

You can also use the Trace node to provide information in error handling in your message flows. For example, you can use this node to record failures in processing because of errors in the content or format of a message.

You can prevent the transaction from being rolled back, and control the extent to which message changes are reversed, by including a TryCatch node in your message flow. If an exception is thrown beyond the Try terminal of the TryCatch node, then an exception list is propagated to the node's Catch terminal. The inflight message reverts to the state it was in before it reached the TryCatch node.

Most message flow nodes have a Catch terminal. These nodes are typically at the start of a transaction, where an uncaught exception would cause a rollback. In these nodes, the Catch terminal behaves as though a TryCatch node was wired directly to the Out terminal. Use the Catch terminal to handle any exceptions that are thrown beyond the message flow node. Wire the Failure terminal to handle errors within the node itself.

Question 5

A developer plans to create two new message flows. Flow1 that uses TimeoutControl and TimeoutNotification nodes in Controlled mode, and Flow2 that uses only the TimeoutNotification node in Automatic mode.

The Integration Node is installed on a system without IBM MQ installed. What problems will the developer encounter?

AFlow1 will not deploy successfully. Flow2 will not deploy successfully.

BFlow1 will not deploy successfully. Flow2 will deploy and execute successfully.

CFlow1 will not deploy successfully. Flow2 will deploy successfully but will produce an error when execution is attempted.

DFlow1 will deploy successfully but produce an error when execution is attempted. Flow2 will deploy and execute successfully.

Answer : B

Information about the state of in-flight messages is held on storage queues that are controlled by WebSphere MQ, so you must install WebSphere MQ on the same computer as your integration node if you want to use the capabilities provided by the TimeoutControl node.

Question 6

Which statement about the XSLTransform node is true?

AThe output of an XSLTransform node is always structured in XML.

BThe XSLTransform node can transform a binary input message into an XML message.

CIn the XSLTransform node, external functions can be called to enrich the transformation.

DThe XSLTransform node can sort the data using the rules defined in the XSLT style sheet.

Answer : D

Use the XSLTransform node (formerly known as the XMLTransformation node) to transform an input XML message into another format using XSLT style sheets and to set the message domain, message set, message type, and message format for the generated message. It is imperative that the data can be parsed into an XML message. The style sheet, using the rules that are defined in it, can perform the following actions:

Question 7

Which statement about the .NETCompute Node is true?

AThe exception is propagated through a predefined output terminal.

B.NETCompute node does not support dynamic terminal. All terminals are predefined.

CThe message assembly contains four trees to represent the message, the environment, the local environment and the exception list.

DOnly when the message needs to be transformed through the .NETCompute node, an Evaluate method is needed. In the case of the message pass-through, there is no need for an Evaluate method.

Answer : A

The Failure Terminal is the output terminal to which the input message is routed if an unhandled exception occurs during the computation.
