質問 # 222
A shopping API contains a method to look up store details by department.
To get the information for a particular store, web clients will submit requests with a query parameter named departmentand uri parameter named storeId What is valid RAML snippet that supports requests from a web client to get a data for a specific storeId and department name?
正解：B
解説：
Lets revise few concepts RAML which can help us to find the answer of this question.
URI Parameters
Lets have a look at below example.
* /foos:
* /{id}:
* /name/{name}:
Here, the braces { } around property names define URI parameters. They represent placeholders in each URI anddo not reference root-level RAML file properties as we saw above in the baseUri declaration. The added lines represent the resources /foos/{id} and /foos/name/{name}.
Query Parameters
Now we'll define a way to query the foos collection using query parameters. Note that query parameters are defined using the same syntax that we used above for data types:
* /foos:
* get:
* description:ListallFoosmatching query criteria,ifprovided;
* otherwise list allFoos
* queryParameters:
* name?:string
* ownerName?:string
Based on the above information , below is the only option which defines storeid as uri parameter and department as query parameter.
* /{storeId}:
* get:
* queryParameter:
* department:
質問 # 223
Refer to the exhibits. The Set Payload transformer in the addltem child flow uses DataWeave to create an orderobject.
What is the correct DataWeave code for the Set Payload transformer in the createOrder flow to use the addltem child flow to add a router call with the price of 100 to the order?
正解：D
質問 # 224
Refer to the exhibits.
What payload and variable are logged at the end of the main flow?
正解：B
解説：
Correctanswer is [[5, 10, 15, 20], 5]
Key thing to note here is that any changes made to payload in for each loop are not available outside for each scope where as variable value updated in for each loop is visible out side for each loop too.
In this example , sequence can be described as follows
1) Payload is set to the value [5, 10, 15, 20]
2) Variable is set to the value of 1
3) For each loop is executed four times and in each loop payload value is updated to append "Req" and variable is count is increased by 1
4) Once control comes out of for each , payload changes made within for each are not visible. Hence payload at this point of time is equal to payload available before entering for each loop which was [5, 10, 15, 20].
Similarly variable value updated in for each loop is also available outside hence variable value is 5 as it was updated in loop.
5) Hence correct answer is [[5, 10, 15, 20], 5]
For Each Scope
The For Each scope splits a payload into elements and processes them one by one through the components that you place in the scope. It is similar to a for-each/for loop code block in most programming languages and can process any collection, including lists and arrays. The collection can be any supported content type, such as application/json, application/java, or application/xml.
General considerations about the For Each scope:
By default, For Each tries to split the payload. If the payload is a simple Java collection, the For Each scope can split it without any configuration. The payload inside the For Each scope is each of the split elements.
Attributes within the original message are ignored because they are related to the entire message.
For Each does not modify the current payload. The output payload is the same as the input.
For non-Java collections, such as XML or JSON, use a DataWeave expression to split data. Use the Collection field for this purpose.
質問 # 225
What is not true about application properties?
正解：B
解説：
Application properties can be defined in .yaml or in .properties file.

質問 # 226
Refer to the exhibits.
This main mule application calls a separate flow called as ShippingAddress which returns the address corresponding to the name of the user sent to it as input. Output of this ShippingAddress is stored in a target variable named address.
Next set of requirement is to have a setPayload transformer which will set below two values
1) orderkey which needs to set to be equal to the order element received in the original request payload.
2) addressKey which needs to be set to be equalto the address received in response of ShippingAddress flow What is the straightforward way to properly configure the Set Payload transformer with the required data?
A mule application is being developed which will process POST requests coming fromclients containing the name and order information. Sample request is as below
正解：A
解説：
Correct answer is as below. In this case address will be stored in a variable. Hence payload will not be overwritten and will contain order details
{
orderkey: "payload.order",
addresskey: "vars.address"
}
