  A RAML example fragment named StudentExample.raml is placed in the examples folder in an API specification project. What is the correct syntax to reference the fragment?

  A. examples: !include StudentExample.raml
  B. examples: #import StudentExample.raml
  C. examples: !include examples/StudentExample.raml
  D. examples: #import examples/StudentExample.raml
  C. examples: !include examples/StudentExample.raml

  ---

  Explanation

  To include property. To keep the API definition concise, you can include external content, such as documentation, schemas, and frequently used patterns outside the definition itself. The parser interprets !include as if the content of the externally-hosted file or a URL were declared in-line. To use the fragments in RAML you have to include the exact path(copy the path) of that fragment you want to use as shown below Option 3 is the correct as correct syntax is examples: !include examples/StudentExample.raml

  What is the correct syntax for a Logger component to output a message with the contents of a 3SON Object payload?

  A. The payload is: $(payload)
  B. #["The payload is: " ++ payload]
  C. The payload is: #[payload]
  D. #["The payload is: " + payload]
  B. #["The payload is: " ++ payload]

  ---

  Explanation

  Option 3 is the only corect answer as it concatenates payload with String.

  Below option wont work.

  #["The payload is " ++ payload]

  Concatenation function expects both arguments to be string. As the question says payload is json object , this will throw error while running it. You can try this in Anypoint Studio and you will get the same result which I mentioned.

  hence correct answer is

  The payload is: #[payload]
