What module and operation will throw an error if a Mule events payload is not number?
A. Filter modules Is Number operation
B. Validation modules Is Number operation
C. Validation modules Is not Number operation
D. None of these
Correct answer is Validation modules Is Number operation.
Mule 4 does not use filters anymore. The functionality provided by filters in Mule 3 can be
achieved by using the Validation Module.
What asset cannot be created using Design Center?
A. Mule Applications
B. API fragments
C. API specifications
D. API portals
Explanation: API portal are created by API Exchange and cannot be created by Design Center

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
* Additionally for
Which of the below activity doesn't support parallel execution?
A. Scatter-Gather Router
B. First Successful Router
C. Parallel For Each
D. Batch job
An organization is beginning to follow Mulesoft's recommended API led connectivity
approach to use modern API to support the development and lifecycle of the integration
solutions and to close the IT delivery gap.
What distinguishes between how modern API's are organized in a MuleSoft recommended
API-led connectivity approach as compared to other common enterprise integration
solutions?
A. The API interfaces are specified as macroservices with one API representing all the business logic of an existing and proven end to end solution
B. The API interfaces are specified at a granularity intended for developers to consume specific aspect of integration processes
C. The API implementation are built with standards using common lifecycle and centralized configuration management tools
D. The APIO implementations are monitored with common tools, centralized monitoring and security systems
Explanation:
Correct answer is The API interfaces are specified at a granularity intended for developers
to consume specific aspect of integration processes.
Refer to the exhibits.

A. 1. 1. {
2. 2. orderkey: "payload.order",
3. 3. addresskey: "vars.address"
4. 4. }
B. 1. 1. {
2. 2. orderkey: "attributes.shippingaddress.order",
3. 3. addresskey: "payload"
4. }
C. 1. 1. {
2. 2. orderkey: "payload.order",
3. 3. addresskey: "address"
4. }
D. 1. 1. {
2. 2. orderkey: "attributes.order",
3. 3. addresskey: "vars.address"
4. }
Explanation:
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"
}
