• Question 113:

  Scenario: A network engineer has created and bound an UDP-ECV monitor to identify the status of a UDP service. However, no matter what the response is, the service is always marked as UP. A possible cause of this behavior is that the network engineer __________. (Choose the correct option to complete the sentence.)

  A. forgot to add a receive string
  B. added the string ns_true as receive string
  C. added a string that is invalid and thus skipped
