Which out-of-the-box key performance indicator measures the success of a typical Center for Enablement and is immediately available in responses from Anypoint Platform APIs?
A. Per business group, the ratio of the number of production APT implementations deployed using a C1/CD pipeline to the number of production API implementations deployed manually
B. Per deployed API implementation, the amount of bandwidth consumed each day
C. Per published API, the number of developers that downloaded s version of the API specification
D. Per published API, the number of consumers that requested access to the API and have been approved in the Production environment
A circuit breaker strategy is planned in order to meet the goal of improved response time
and demand on a downstream API.
A. Create a custom policy that implements the circuit breaker and includes policy template expressions for the required settings
B. Create Anypoint Monitoring alerts for Circuit Open/Closed configurations, and then implement a retry strategy for Circuit Half-Open configuration
C. Add the Circuit Breaker policy to the API instance, and configure the required settings
D. Implement the strategy in a Mule application, and provide the settings in the YAML configuration
Say, there is a legacy CRM system called CRM-Z which is offering below functions:
1. Customer creation
2. Amend details of an existing customer
3. Retrieve details of a customer
4. Suspend a customer
A.
Implement a system API named customerManagement which has all the functionalities
wrapped in it as various operations/resources
B.
Implement different system APIs named createCustomer, amendCustomer,
retrieveCustomer and suspendCustomer as they are modular and has seperation of concerns
C.
Implement different system APIs named createCustomerInCRMZ,
amendCustomerInCRMZ, retrieveCustomerFromCRMZ and suspendCustomerInCRMZ as
they are modular and has seperation of concerns
Implement different system APIs named createCustomer, amendCustomer,
retrieveCustomer and suspendCustomer as they are modular and has seperation of concerns
Correct Answer: Implement different system APIs named createCustomer,
amendCustomer, retrieveCustomer and suspendCustomer as they are modular and has
seperation of concerns
*****************************************
>> It is quite normal to have a single API and different Verb + Resource combinations.
However, this fits well for an Experience API or a Process API but not a best architecture
style for System APIs. So, option with just one customerManagement API is not the best
choice here.
>> The option with APIs in createCustomerInCRMZ format is next close choice w.r.t
modularization and less maintenance but the naming of APIs is directly coupled with the
legacy system. A better foreseen approach would be to name your APIs by abstracting the
backend system names as it allows seamless replacement/migration of any backend
system anytime. So, this is not the correct choice too.
>> createCustomer, amendCustomer, retrieveCustomer and suspendCustomer is the right
approach and is the best fit compared to other options as they are both modular and same
time got the names decoupled from backend system and it has covered all requirements a
System API needs.
What best explains the use of auto-discovery in API implementations?
A. It makes API Manager aware of API implementations and hence enables it to enforce policies
B. It enables Anypoint Studio to discover API definitions configured in Anypoint Platform
C. It enables Anypoint Exchange to discover assets and makes them available for reuse
D. It enables Anypoint Analytics to gain insight into the usage of APIs
Explanation: Explanation
Correct Answer: It makes API Manager aware of API implementations and hence enables it
to enforce policies.
*****************************************
>> API Autodiscovery is a mechanism that manages an API from API Manager by pairing
the deployed application to an API created on the platform.
>> API Management includes tracking, enforcing policies if you apply any, and reporting
API analytics.
>> Critical to the Autodiscovery process is identifying the API by providing the API name
and version.

An API implementation returns three X-RateLimit-* HTTP response headers to a requesting API client. What type of information do these response headers indicate to the API client?
A.
The error codes that result from throttling
B.
A correlation ID that should be sent in the next request
C.
The HTTP response size
D.
The remaining capacity allowed by the API implementation
The remaining capacity allowed by the API implementation
Explanation: Explanation
Correct Answer: The remaining capacity allowed by the API implementation.

Which scenario is suited for MUnit tests instead of integration tests?
A. For read-only interactions to any dependencies (such as other web APIs)
B. When testing does not require knowledge of implementation details
C. When no mocking is permissible
D. For tests that are implemented using SoapUI
Explanation:
MUnit is MuleSoft’s testing framework for creating and running automated
tests within Anypoint Studio. It is specifically designed for unit testing Mule applications and
is best suited when testing doesn’t require understanding the inner workings or
implementation details of the components being tested.
When must an API implementation be deployed to an Anypoint VPC?
A.
When the API Implementation must invoke publicly exposed services that are deployed outside of CloudHub in a customer- managed AWS instance
B.
When the API implementation must be accessible within a subnet of a restricted customer-hosted network that does not allow public access
C.
When the API implementation must be deployed to a production AWS VPC using the Mule Maven plugin
D.
When the API Implementation must write to a persistent Object Store
When the API Implementation must invoke publicly exposed services that are deployed outside of CloudHub in a customer- managed AWS instance
What correctly characterizes unit tests of Mule applications?
A.
They test the validity of input and output of source and target systems
B.
They must be run in a unit testing environment with dedicated Mule runtimes for the environment
C.
They must be triggered by an external client tool or event source
D.
They are typically written using MUnit to run in an embedded Mule runtime that does not require external connectivity
They are typically written using MUnit to run in an embedded Mule runtime that does not require external connectivity
Explanation: Explanation
Correct Answer: They are typically written using MUnit to run in an embedded Mule runtime
that does not require external connectivity.
*****************************************
Below TWO are characteristics of Integration Tests but NOT unit tests:
>> They test the validity of input and output of source and target systems.
>> They must be triggered by an external client tool or event source.
It is NOT TRUE that Unit Tests must be run in a unit testing environment with dedicated
Mule runtimes for the environment.
MuleSoft offers MUnit for writing Unit Tests and they run in an embedded Mule Runtime
without needing any separate/ dedicated Runtimes to execute them. They also do NOT
need any external connectivity as MUnit supports mocking via stubs.
