• Question 21:

  A solution developer codes a JavaCompute node using a getJDBCType4Connection API call to connect to a JDBC database that is globally coordinated, and then writes code to insert new records into that database based on the contents of incoming MQ messages. The solution developer observes that database inserts are not rolled back if the message flow experiences an error after this Compute node. What must the solution developer do to correct this?

  A. Alter the code to use MbSQLStatement

  B. Insert code to issue statements to rollback

  C. Alter the Transaction Mode of the JavaCompute node to commit

  D. Alter the type4DatasourceClassName property of the JDBCProvider

  Correct Answer: D

• Question 22:

  A solution developer is writing a message flow using the XMLNSC domain. Testing is producing the wrong output, and the solution developer is uncertain which node is causing the error. The solution developer adds a Trace node to display the contents of the data being passed. Which Trace node pattern will display the contents of the data?

  A. ${Root}

  B. ${XMLNSC}

  C. ${InputRoot}

  D. ${InputXMLNSC}

  Correct Answer: A

• Question 23:

  A solution developer needs to read records from a file every hour and insert them into a database. The solution developer creates a flow using a TimeoutNotification node to start the flow, a FileRead node to read individual records from the file and a Compute node to insert the records into the database. To ensure that all records are processed in a unit of work, what must the solution developer do?

  A. Check the Throw exception on database error option

  B. Set the Transaction Mode of the TimeoutNotification node to Yes

  C. Set the Record Detection option of the FileRead node to Whole File

  D. Set the Operation Mode of the TimeoutNotification node to Controlled

  Correct Answer: B

• Question 24:

  A solution developer is requested to investigate a message flow using the DFDL parser that is performing slowly. The message contains several optional fields. The solution developer determines that the parser is backtracking extensively while parsing input messages. What action should the solution developer take to reduce the amount of time required to parse the messages?

  A. Restructure the input messages.

  B. Use the XML parser instead of the DFDL parser.

  C. Include dfdl:discriminator and initiator keywords in the DFDL schema.

  D. Force the parser to reduce backtracking by suppressing errors that occur at parse time.

  Correct Answer: C

• Question 25:

  A sales company is currently running 2 message flows. The first, ProcessOrder, validates customer orders and then sends the shipping information to the warehouse via an MQ request message. Once the warehouse has shipped the order, a reply is sent back which is processed by the second flow, SendConfirmation, to send a confirmation to the customer. The company is now expanding and has multiple warehouses. The solution developer must modify ProcessOrder to send messages to each warehouse only for the items it stocks, and SendConfirmation to send a response message only when all warehouses have replied. What node(s) should the solution developer use?

  A. SendConfirmation -> MQGet

  B. SendConfirmation -> Collector

  C. ProcessOrder -> Sequence SendConfirmation -> Resequence

  D. ProcessOrder -> AggregateControl and AggregateRequest SendConfirmation -> AggregateReply

  Correct Answer: D

• Question 26:

  A solution developer needs to import a WSDL into an Application. The WSDL references a set of XML Schemas that contain xsd:import statements as well as xsd:redefine statements. What happens when the solution developer imports this WSDL into an Application?

  A. The XSDs are imported without error into the main application

  B. A pop-up dialog appears asking the developer how to resolve the redefine statements.

  C. The WSDL and XSDs are imported, but errors appear saying that redefines are not supported.

  D. The WSDL is imported into the main application, the XSDs are imported into a dependent Library

  Correct Answer: C

• Question 27:

  A solution developer implemented a message flow for a book store company which receives an XML input message. The input message is formed according to an XML schema supplied by the client and used by several other applications owned by the company. The input node uses XMLNSC parser to parse the input message. The image below depicts a sample XML input message. According to business needs, the bookDetails elements and all of its children are not referenced by the code. Performance test for the flow showed a significant time spent in message parsing time especially for large messages.

  

  What should the solution developer do to enhance the message parsing time ?

  A. Use the MRM parser instead.

  B. Set the parse timing to Complete.

  C. Set the parse timing option to On Demand.

  D. Add the bookDetails element to the XMLNSC parse Opaque elements

  Correct Answer: D

• Question 28:

  A bank uses an online system to handle currency transactions, sent via MQ messaging. To avoid multiple database lookups to obtain the latest currency exchange rates, the rates are loaded into shared variables the first time the flow is executed. Periodic updates to the shared variables are made using a control message. As the volume of transactions increases, it is realized that a single instance of the flow can no longer cope, and so the solution developer is asked to investigate ways to increase throughput. How can the solution developer increase the message throughput?

  A. Define multiple instances of the flow on the BAR file.

  B. Deploy the flow to multiple execution groups.

  C. Deploy multiple instances of the flow in different schemas.

  D. Deploy the flow to a second broker and use MQ Clustering to redistribute these messages.

  Correct Answer: A

• Question 29:

  A solution developer uses ESQL to transform messages. Which options can the solution developer use to delete a message field or message structure? (Choose three)

  A. Set the value to 0

  B. Set the value to NULL

  C. Set the value to ""(Empty String)

  D. Use the ATTACH statement

  E. Use the DETACH statement

  F. Use the DELETE statement

  Correct Answer: BEF

• Question 30:

  A healthcare company needs to implement WS-Security integrity message signing for an existing web service flow that will now be handling sensitive data. Which nodes can the solution developer use to develop this enhancement? (Choose two)

  A. HTTPInput

  B. HTTPRequest

  C. SOAPInput

  D. SOAPRequest

  E. SOAPEnvelope

  Correct Answer: CD
