Answer: D
Explanation:
*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

NEW QUESTION # 98
What is output of Dataweave flatten function?
- A. Object
- B. Map
- C. LInkedHashMap
- D. Array
Answer: D
Explanation:
Correct answer isArray.
Flatten turns a set of subarrays (such as [ [1,2,3], [4,5,[6]], [], [null] ]) into a single, flattened array (such as [
1, 2, 3, 4, 5, [6], null ]).
This example defines three arrays of numbers, creates another array containing those three arrays, and then uses the flatten function to convert the array of arrays into a single array with all values.
Source
%dw 2.0
output application/json
var array1 = [1,2,3]
var array2 = [4,5,6]
var array3 = [7,8,9]
var arrayOfArrays = [array1, array2, array3]
---
flatten(arrayOfArrays)
Output
[ 1,2,3,4,5,6,7,8,9 ]

How should the WHERE clause be changed to set the city and state values from the configured input parameters?
- A.
- B.
- C.
- D.
Answer: B
NEW QUESTION # 100
Refer to the exhibit.
How should be the where clause written for the configured input parameters in such a way that it achieves below SQL query?
- A. WHERE city = attributes.cityAND state = attributes.state
- B. WHERE city := city AND state := state
- C. WHERE city = :city AND state = :state
- D. WHERE city := ${city} AND state := ${state}
Answer: C
Explanation:
Correct syntax to use where clause is WHERE city = :city AND state = :state This question validates knowledge on using dynamicqueries in DB select operation.
Configure Dynamic Queries in the Select Operation
When you need to parameterize not only the WHERE clause but also parts of the query itself (for example, queries that compare tables that depend on a condition, or complexqueries for which the project table columns need to vary), you can configure dynamic queries.
In the following example, you configure a dynamic query by using a full expression with a string in which the table depends on a variable $(vars.table). Althoughsome of the query text is dynamic ("SELECT * FROM
$(vars.table)), the WHERE clause still defines the WHERE condition using input parameters: in this case, WHERE name = :name.
In your Studio flow, select the Select operation.
In the operation configurationscreen, set the SQL Query Text field to SELECT * FROM $(vars.table) WHERE name = :name.
Set the Input Parameters field to {'name' : payload}.
The following screenshot shows the configuration in Studio:

Figure 3. Dynamic query configuration
In the XML editor, the <db:sql> configuration looks like this:
* <set-variablevariableName="table"value="PLANET"/>
* <db:selectconfig-ref="dbConfig">
* <db:sql>#["SELECT * FROM $(vars.table) WHERE name = :name"]</db:sql>
* <db:input-parameters>
* #[{'name' : payload}]
* </db:input-parameters>
* </db:select>
You can apply input parameters only to parameters in a WHERE clause. To modify any other part of the query, use the DataWeave interpolation operator.

Refer to the exhibits.
The Validation component in theTry scope throws an error.
What response message is returned to a client request to the main flow's HTTP Listener?
The Validation component in the Try scope throws an error. What response message is returned to a client request to the main flow's HTTP Listener?
- A. Error - Try scope
- B. Validation Error
- C. Error - main flow
- D. Success - main flow
Answer: D
Explanation:
Note that private flow has error scope defined as On Error Continue . So when error occurs in private flow , it is handled by this On Error Continue scopewhich sends success response back to main flow and does not throw back an error. So main continues normally and payload is set to Success - main flow.
Hence correct answer is Success - main flow
1) HTTP listener received request
2) The Flow Referencecalls the child flow
3) The Is Number validator creates an Error Object because the payload isn't an integer. Child Flow execution stops
#[error.description] = "payload is not a valid INTEGER value"
#[error.errorType] = VALIDATION:INVALID_NUMBER
4) The OnError Continue handles the errorThe payload is set to "Error - Sub Flow"
5) "Error - Sub Flow" is returned to the main flow as if the child flow was a success. The Set Payload is executed. The payload is reset to "Success - Finished Main Flow"
6) "Success- Main Flow" is returned to the requestor in the body of the HTTP request. HTTP Status Code:
200
As you can see, in the above example, because the error was caught by an On Error Continue scope in the child flow (RED in, GREEN out) when the Mule Message returns to the parent flow, the parent flow knows none-the-different that there was a failure because the on error continue returns a 200 success message. Note that because, to the mainFlow, the childFlow appeared to succeed, the processing of mainFlow resumed after the flow reference.
