• Question 114:

  Refer to the exhibits.

  

  The Batch Job scope contains two Batch Steps scopes with different accept expression.

  The input payload is passed to the Batch Job scope.

  After the entire payload is processed by the batch job scope , what messages have been logged by the Logger component?

  A. 1.{amount=140} 2.{amount=102} 3.{step2amount=100}
  B. 1.{amount=140} 2.{amount=102} 3.{step2amount=100} 4.{step2amount=40}
  C. 1.{amount=140} 2.{amount=102} 3.{step2amount=100} 4.{step2amount=140}
  D. 1.{amount=140} 2.{amount=102} 3.{step2amount=100} 4.{step2amount=140} 5.{step2amount=102}
  D. 1.{amount=140} 2.{amount=102} 3.{step2amount=100} 4.{step2amount=140} 5.{step2amount=102}

  ---

  Explanation/Reference:

  Lets understand this solution step by step.

  1) Batch Step (Less than 50)

  Accept expression for this batch step is less than 50. Hence elements which will go in this batch step are amount value 40 and 2. Hence output of logger in first batch step is {amount=140} {amount=102}

  2) Batch Step (Greater than 20)

  Accept condition for this batch step is greater than 20. Note that input amount values for this batch step are 100 , 140 and 102 (last two values have been updated in batch step less than 50) As all values satisfy this condition out put of second

  logger is {step2amount=100}

  {step2amount=140}

  {step2amount=102}

  Hence correct answer to this question is

  

  {amount=140} {amount=102} {step2amount=100} {step2amount=140} {step2amount=102}

• Question 115:

  What is the correct way to format the decimal 200.1234 as a string to two decimal places?

  A. 200.1234 as string as format: ".0#"
  B. 200.1234 as String {format: ".0#"}
  C. 200.1234 as String as format: ".0#"
  D. 200.1234 as string {format: ".0#"}
  B. 200.1234 as String {format: ".0#"}

  ---

  Explanation/Reference:

  Correct answer is 200.1234 as String {format: ".0#"} . Rest all options are not syntactically correct.

• Question 116:

  Refer to the exhibit.

  

  What payload is returned from a request to http//localhost.8081/

  Refer to the exhibits, what payload is returned from a request to http://localhost;8081/?

  A. 1
  B. 2
  C. 3
  D. 4
  C. 3

  ---

  Explanation/Reference:

  The flow can be described as below. 1) First HTTP POST requets is made in which paylaod is set to 1 and it gets returned to our mail flow. 2) Second call is initiated for JMS Publish Consume JMS: num1 which add 1 to the payload which makes it as 2. Note that pubih consume is a synchronous operation. Hence paylaod is returned to main flow. 3) Third call is initiated for JMS Publish JMS: num2 which add 1 to the payload . Note that pubih is asynchronous operation. Hence paylaod is never returned to main flow. So payload in main flow is still 2. 4) Finally Set Payload increments payload by 1 making payload as 3 which is returned by the flow. Hence option 3 is the correct answer.

• Question 117:

  Refer to the exhibits.

  

  The Batch job processes an array of strings.

  What information is logged by the logger component after the batch job scope completes processing of the input payload?

  A. Total Records Processed: 3 Successful Records: 3 Failed Records: 0 payload: ["A","B","C"]
  B. ["A","B","C"]
  C. Total Records Processed: 3 Successful Records: 3 Failed Records: 0 payload: ["a", "b", "c"]
  D. Total Records Processed: 3 Successful Records: 3 Failed Records: 0
  D. Total Records Processed: 3 Successful Records: 3 Failed Records: 0

  ---

  Explanation/Reference:

  Correct answer is as below. On complete phase only has access to batch job result statistics and payload is not available. Total Records Processed: 3 Successful Records: 3 Failed Records: 0

  B. Object
  C. Array
  D. Map
  C. Array

• Question 120:

  Refer to the exhibits.

  

  A web client submits a request to the HTTP Listener and the HTTP Request throws an error.

  What payload and status code are returned to the web client?

  Refer to the exhibits. A web client submits a request to the HTTP Listener and the HTTP Request throws an error.

  What payload and status code are returned to the web client?

  A. Response body: "Error" Default response status code: 200
  B. Response body: "Success - Begin* Default response status code: 200
  C. Error response body: error, description Default error response status code: 500
  D. Response body: "Success - End" Default response status code: 200
  A. Response body: "Error" Default response status code: 200

  ---

  Explanation/Reference:

  Correct Answer: Response body: "Error" Default response status code: 200.

  1) Payload is successfully set to "Success ?Started Flow"

  2) When HTTP Request throws an error, execution halts

  #[error.description] = "ABC"

  #[error.errorType] = "XYZ"

  3) The On Error Continue scope handles the error. When On Error Continue scope is invoked, all the processors in error block are executed and success response is sent back to the client with payload which is set in error flow. In this case

  payload is set to "Error" value in error block.

  4) "Error" is returned to the requestor in the body of the HTTP request with HTTP Status Code: 200 as On error continue always sends success error code.
