Question 6

A solution developer is defining a DFDL model for a file that defines a purchase order. A field in the header, ItemCount, defines the number of purchase order items contained in the purchase order. The schema model is defined as shown below. What modification must the developer make to the model to ensure that the number of items in the purchase order is equal to the value in ItemCount?

  1. Set the OccursCountKind property to Implicit.
  2. Add an Assert to Items that tests that items is less than or equal to ItemCount.
  3. Add a variable instance to the sequence element that counts the number of Items records.
  4. Set the OccursCountKind property for Items to Expression and set the expression to {../Header/ItemCount}.

Question 7

A solution developer encounters a problem while testing a message flow starting with the MQInput node and using the XMLNSC domain. The solution developer added a trace node wired to the output terminal of the MQInput node to display the contents of the data being passed. Which value does the solution developer need to set for the trace pattern to display the entire message?

  1. $ {Root}
  2. $ {XMLNSC}
  3. $ {InputRoot}
  4. $ {InputRoot. XMLNSC }

Question 8

A solution developer wants to monitor how much Java processing memory is currently allocated to an integration server. A flow is currently deployed. Assuming resource statistics collection has been started, which step will allow the developer to obtain these statistics?

  1. Expand Integration Nodes folder in IBM Integration Explorer Choose Window menu: Show view: Resource statistics Click JVM tab, and view CommittedMemoryInMB measurement
  2. Expand Integration Nodes folder in IBM Integration Explorer Choose Window menu: Show view: Resource statistics Click JVM tab, and view UsedMemoryinMB measurement
  3. Expand Integration Nodes in IBM Integration Toolkit Choose Window menu: Show view: Resource statistics Click JVM tab, and view UsedMemoryinMB measurement
  4. Expand Integration Nodes in IBM Integration Toolkit Choose Window menu: Show view: Resource statistics

Question 9

A solution developer is analyzing the of a message flow. There are a number of references defined in the ESQL code of the Compute node. Why should the developer use dynamic references in the ESQL code of the message flow?

  1. It is a technique to reduce tree copying in a message flow.
  2. It is a technique to reduce tree navigation when accessing repeating elements in a message tree.
  3. References allow the usage of optimized code from dynamically loaded external libraries.
  4. By creating a reference, intermediary results can be cached and so memory usage is reduced.
