NO.37 A
web client submits a request to http://localhost:8081?accountType=personal. The query parameter is captured using a Set Variable transformer to a variable named accountType.
What is the correct DataWeave expression to log accountType?

Account Type: #[flowVars.accountType]

Account Type: #[message.inboundProperties.accountType]

Account Type: # [attributes.accountType]

Account Type: #[vars.accountType]

vars: Keyword for accessing a variable, for example, through a DataWeave expression in a Mule component, such as the Logger, or from an Input or Output parameter of an operation. If the name of your variable is myVar, you can access it like this: vars.myVar Hence correct answer is Account Type: #[vars.accountType]

NO.42 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?

Incoming array objects would be split into three and each part would be sent to one route each in sequential manner

Incoming array objects would be split into three and each part would be sent to one route each in parallel

Entire event would be sent to each route sequentially

Entire event would be sent to each route in parallel

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.

NO.46 Refer to the below exhibit. A Mule application configures a property placeholder file named config.yaml to set some property placeholders for an HTTP connector.
What is the valid properties placeholder file to set these values?

2. host = “localhost”
3. port = “8081”

1. http:
2. basepath: “api”
3. host : “localhost”

NO.49 Refer to the exhibits.

A web client submits a request to the HTTP Listener and the HTTP Request throws an error.
What payload and status code are returned to the web client?
Refer to the exhibits. A web client submits a request to the HTTP Listener and the HTTP Request throws an error.
What payload and status code are returned to the web client?

Response body: “Error” Default response status code: 200

Response body: “Success – Begin* Default response status code: 200

Error response body: error, description Default error response status code: 500

Response body: “Success – End” Default response status code: 200

Correct answer: Response body: “Error” Default response status code: 200.
————————————————————————————————————————————————-
1) Payload is successfully set to “Success – Started Flow”
2) When HTTP Request throws an error, execution halts
#[error.description] = “ABC”
#[error.errorType] = “XYZ”
3) The On Error Continue scope handles the error. When On Error Continue scope is invoked, all the processors in error block are executed and success response is sent back to the client with payload which is set in error flow. In this case payload is set to “Error” value in error block.
4) “Error” is returned to the requestor in the body of the HTTP request with HTTP Status Code: 200 as On error continue always sends success error code.
