B. #["Content-Type: " + attributes.headers.'content-type']
C. #["Content-Type: " ++ headers.'content-type']
D. #["Content-Type: " ++ attributes.headers.'content-type']

NEW QUESTION # 182
There are three routes configured for Scatter-Gather and incoming event has a payload is an Array of three objects. How routing will take place in this scenario?

A. Incoming array objects would be split into three and each part would be sent to one route each in sequential manner
B. Entire event would be sent to each route in parallel
C. Incoming array objects would be split into three and each part would be sent to one route each in parallel
D. Entire event would be sent to each route sequentially

Answer: B

Explanation:
Entire event would be sent to each route in parallel.
Scatter-Gather works as follows :
- The Scatter-Gather component receives a Mule event and sends a reference of this Mule event to each processing route.
- Each of the processing routes starts executing in parallel. After all processors inside a route finish processing, the route returns a Mule event, which can be either the same Mule event without modifications or a new Mule event created by the processors in the route as a result of the modifications applied.
- After all processing routes have finished execution, the Scatter-Gather component creates a new Mule event that combines all resulting Mule events from each route, and then passes the new Mule event to the next component in the flow.

NEW QUESTION # 183
What happens to the attributes of a Mule event in a flow after an outbound HTTP Request is made?

A. Attributes are replaced with new attributes from the HTTP Request response (which might be null)
B. New attributes may be added from the HTTP response headers, but no headers are ever removed
C. Previous attributes are passed unchanged
D. Attributes do not change

Answer: A

Explanation:
Attributes are replaced with new attributes from the HTTP Request response.
Attributes include everything apart from Payload/body. For ex: Headers, query parameters, URI parameters.
So, when outbound HTTP request is made, new attributes need to pass the outbound HTTP request and old attributes are replaced.
