DEX401 Sample Exam Questions and Answers
| QUESTION: 1 |
| 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? Option A: Incoming array objects would be split into three and each part would be sent to one route each in sequential manner Option B: Incoming array objects would be split into three and each part would be sent to one route each in parallel Option C: Entire event would be sent to each route sequentially Option D: Entire event would be sent to each route in parallel |
| Correct Answer: D |
| Explanation/Reference: 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. |
| QUESTION: 2 |
| A Scatter-Gather processes three separate HTTP requests. Each request returns a Mule event with a JSON payload. What is the final output of the Scatter-Gather? Option A: An Array of the three Mule event Objects Option B: An Object containing all three Mule event Objects Option C: An Array of the three JSON payload Objects Option D: An Object containing all three JSON payload Objects |
| Correct Answer: B |
| Explanation/Reference: Correct answer isAn Object containing all three Mule event Objects The Scatter-Gather component is a routing event processor that processes a Mule event through different parallel processing routes that contain different event processors. Each route receives a reference to the Mule event and executes a sequence of one or more event processors. Each of these routes uses a separate thread to execute the event processors, and the resulting Mule event can be either the same Mule event without modifications or a new Mule event with its own payload, attributes, and variables. The Scatter-Gather component then combines the Mule events returned by each processing route into a new Mule event that is passed to the next event processor only after every route completes successfully. The Scatter-Gather component executes each route in parallel, not sequentially. Parallel execution of routes can greatly increase the efficiency of your Mule application and may provide more information than sequential processing. Sample output is as below |
| QUESTION: 3 |
| A web client submits a request to http://localhost:8081?flrstName=john. What is the correct DataWeave expression to access the firstName parameter? Option A: #[attributes.queryParams.firstName] Option B: #[message.queryParams.hrstName] Option C: #[message.inboundProperties.’http.query.params’.firstName] Option D: #[attributes.’http.query.params’.firstName] |
| Correct Answer: A |

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] description: Gets a list of JSONPlaceholder users. |

| QUESTION: 9 |
| Which keyword do you use to create a new function in DataWeave? Option A: function Option B: fun Option C: func Option D: map |
| Correct Answer: B |
| Explanation/Reference: You can define your own DataWeave functions using the fun declaration in the header of a DataWeave script. Sample is as below. —————————————- %dw 2.0 output application/json fun toUpper(aString) = upper(aString) — toUpper(‘hello’) MuleSoft Doc Ref : https://docs.mulesoft.com/mule-runtime/4.1/dataweave-functions |
| QUESTION: 10 |
| A Batch Job scope has five batch steps. An event processor throws an error in the second batch step because the input data is incomplete. What is the default behavior of the batch job after the error is thrown? Option A: All processing of the batch job stops. Option B: Event processing continues to the next batch step. Option C: Error is ignored Option D: Batch is retried |
| Correct Answer: A |
| Explanation/Reference: In case of an error , batch job completes in flight steps and stops further processing. MuleSoft Doc Ref : Handling Errors During Batch Job | MuleSoft Documentation The default is all processing will stop but we can change it by Max Failed Record field. General -> Max Failed Records: Mule has three options for handling a record-level error: Finish processing, Continue processing and Continue processing until the batch job accumulates a maximum number of failed records. This behavior can be controlled by Max Failed Records. The default value is Zero which corresponds to Finish processing. The value -1, corresponds to Continue processing. The value +ve integer, corresponds to Continue processing until the batch job accumulates a maximum number of failed records |
