Question 1
A message flow reads messages from a queue Database Node fails to insert data in the table. If no error handling and rollback is implemented in the message flow,
which of the following statements is true?
- The transaction is by default rolled back in a globally coordinated manner.
- The message fails the Input Node and cannot be propagated out of the Out terminal. The transaction is rolled back.
- The error is caught by the MQ Input Node and if the Catch terminal is not connected the message is rolled back into the queue.
- The message flow rolls back the database transaction but not the MQ transaction unless a XA coordinated transaction is configured.
Correct answer: C
Explanation:
The MQInput node takes certain actions when handling errors with persistent and transactional messages. The node attempts retry processing when a transactional message is rolled back to the input queue. Non-transactional messages are not rolled back to the input queue when an exception occurs. If the MQInput node has successfully propagated the message to the out terminal and an exception is thrown in the out flow, the message is returned to the MQInput node:If you have not connected the Catch terminal, the message is rolled back to the input queue. The MQInput node writes the error to the local error log and invokes the retry logic, described in Handling retry processing. If you have connected the Catch terminal, you are responsible for handling the error in the flow connected to the Catch terminal. The broker creates a new exception list to represent the error and this list is propagated to the Catch terminal as part of the message tree, but neither the MQInput node nor the broker provide any further failure processing.

MQInput node:
- If you have not connected the Catch terminal, the message is rolled back to the input queue. The MQInput node writes the error to the local error log andinvokes the retry logic, described in Handling retry processing.

Question 2
A developer creates a message flow that uses a DecisionService Node. Which command must the developer use before deploying the message flow?
- mqsicvp
- mqsimode
- mqsichangebroker
- mqsichangeproperties
Correct answer: B
Explanation:
Before you deploy message flows that contain a DecisionService node, you must enable the mode extension by using the mqsimode command:mqsimode -x DecisionServices Incorrect Answers:A: The mqsicvp command is run automatically when you start a broker by using the mqsistart command. The command checks that the broker environment is set up correctly. This checking has been enhanced to verify that the ODBC environment is configured correctly on Linux and UNIX systems.

Question 3
In the User Trace output shows the following message:
2016-04-12 16:17:18.242605 5344 UserTrace BIP2539I: Node
'Reply.MapToRequestor':
Evaluating expression ''I + 1''
at
('MapToRequestor.CopyMessageHeaders', '6.14'). This resolved to ''1 + 1''. The result was ''2''.
What does 6.14 indicate here?
- Line 6, Column 14 in the CopyMessageHeaders node.
- Line 14, Column 6 in CopyMessageHeaders node.
- Column 6, line 14 in the CopyMessageHeaders function of MapToRequestor.
- Line 6, Column 14 in the CopyMessageHeaders function of MapToRequestor.
Correct answer: D
Explanation:
References such as '6.14' apply to the row and column number within a function that specify the location of the command that is being executed; in this case, row 6, column 14. Example:2005-07-12 16:17:18.242605 5344 UserTrace BIP2539I: Node 'Reply.MapToRequestor':Evaluating expression ''I'' at ('.MapToRequestor.CopyMessageHeaders', '6.12'). This resolved to ''I''. The result was ''1''.
