What is the trait name you would use for specifying client credentials in RAML?
A. headers
B. client-id
C. client-id-required
D. cannot be specified in RAML
Explanation:
client-id-required enforces clients to add client_id and client_secret.
Please refer to below steps.
Add a section called traits: at the root level to define query parameters:
•traits:
- client-id-required:
queryParameters:
client_id:
type: string
client_secret:
type: string
2) Reference the trait in each of the methods to specify that each of the methods
require these query parameters. After each method in the RAML file, add is:
[client-id-required]. For example:
/users:
get:
is: [client-id-required]

route.
MuleSoft Doc Ref : https://docs.mulesoft.com/mule-runtime/4.1/choice-router-concept
The Choice router dynamically routes messages through a flow according to a set of
DataWeave expressions that evaluate message content. Each expression is associated
with a different routing option. The effect is to add conditional processing to a flow, similar
to an if/then/else code block in most programming languages.
Only one of the routes in the Choice router executes, meaning that the first expression that
evaluates to true triggers that route’s execution and the others are not checked. If none of
the expressions are true, then the default route executes.
Refer to the exhibit. 
In the execution of the Scatter_Gather, the flow1 route completes after 10 seconds and the
flow2 route completes after 20 seconds.
How many seconds does it take for the Scatter_Gather to complete?
A.

10
C.
