Answer : D

* RAML file contains lot of information that could be considered as 'not API-describing'. Sort of 'economy-class' members.

Equally important, but not necessarily part of the main RAML file.

* Through !includes, RAML allows us to build file-distributed API definitions, which is not only useful to encourage code reuse but also improves readability.

* We can create RAML fragments with such code and then include them in main RAML project using !include like:

types:

Book: !include bookDataType.raml and

examples:

input: !include bookExample.raml

* Additionally for

Question 7

Refer to the exhibits.

The Mule application configures and uses two HTTP Listener global configuration elements.

Mule application is run in Anypoint Studio.

If the mule application starts correctly, what URI and port numbers can receive web client requests? If the mule applications fails to start , what is the reason for the failure?

AThe mule application fails to start
There is URL path conflict because both HTTP Listeners are configured with same path

BThe mule application start successfully
Web client requests can only be received at URI on port 2222 but not on port 3333

CThe mule application fails to start because of the port binding conflict as HTTP request also use same port i.e. 3333

DThe mule application start successfully
Web client requests can be received at URI on port 2222 and on port 3333.

Answer : D

In this case both the flows can start without any error and requests can be received on both ports. Flow names httpListener1 can call other flow using HTTP request without any issues.

Hence correct answer is

The mule application start successfully

Web client requests can be received at URI on port 2222 and on port 3333.

Lets check why other options are incorrect

1) The mule application fails to start. There is URL path conflict because both HTTP Listeners are configured with same path ---- This is incorrect as port value is different in both listeners

2) The mule application start successfully. Web client requests can only be received at URI on port 2222 but not on port 3333 --- This is incorrect as there is no reason for not receiving requests on port 3333

3) The mule application fails to start because of the port binding conflict as HTTP request also use same port i.e. 3333 --- Port binding conflict will not happen in this case. It would have if both listener configurations would have been on same port . But that is not the case here.
