Mulesoft MCPA-Level-1 Exam Questions

A.   

The visibility level of the API instances of that API that need to be publicly accessible should be set to public visibility

Explanation: Explanation

B.   

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.

B.   

API Consumer requests access to API >> API Client implementes logic to call an API >>
API routes the request to >> API Implementation

Explanation: Explanation
Correct Answer: API Consumer requests access to API >> API Client implementes logic to
call an API >> API routes the request to >> API Implementation
*****************************************
>> API consumer does not implement any logic to invoke APIs. It is just a role. So, the
option stating "API Consumer implementes logic to call an API" is INVALID.
>> API Implementation does not route any requests. It is a final piece of logic where
functionality of target systems is exposed. So, the requests should be routed to the API
implementation by some other entity. So, the options stating "API Implementation routes
the request to >> API" is INVALID
>> The statements in one of the options are correct but sequence is wrong. The sequence
is given as "API Client implementes logic to call an API >> API Consumer requests access
to API >> API routes the request to >> API Implementation". Here, the statements in the
options are VALID but sequence is WRONG.
>> Right option and sequence is the one where API consumer first requests access to API
on Anypoint Exchange and obtains client credentials. API client then writes logic to call an
API by using the access client credentials requested by API consumer and the requests will
be routed to API implementation via the API which is managed by API Manager

C.   MuleSoft-hosted runtime plane (CloudHub)

Explanation:
For a European company with requirements such as zero-downtime redeployment, deployment to multiple runtime versions, secure and fast performance, and the use of Anypoint MQ without additional network configuration, CloudHub is the best choice for the following reasons:

• Zero-Downtime Redeployment: CloudHub supports zero-downtime deployment, which allows seamless redeployment of applications without impacting availability. Support for Multiple Runtime Versions: CloudHub allows deploying applications across different Mule runtime versions, giving flexibility to test and migrate applications as needed.
• Integrated Anypoint MQ: Anypoint MQ, which is fully integrated with CloudHub, provides reliable messaging across applications. Choosing CloudHub removes the need for additional network configurations, as Anypoint MQ can be directly accessed in this hosted environment.
• Security and Performance: CloudHub offers secure networking, automatic scaling, and optimized performance without requiring a complex setup. This is managed by MuleSoft’s infrastructure, meeting the speed and security requirements with minimal overhead.

Explanation of Incorrect Options:
References:
For more information on CloudHub’s capabilities regarding zero-downtime deployments and integration with Anypoint MQ, refer to MuleSoft documentation on CloudHub.

D.   

A Non-Mule application

Explanation: Explanation
Correct Answer: A Non-Mule application
*****************************************
>> All type of Mule applications (Mule 3/ Mule 4/ with APIkit/ with Custom Java Code etc)
running on Mule Runtimes support the Embedded Policy Enforcement on them.
>> The only option that cannot have or does not support embedded policy enforcement
and must have API Proxy is for Non-Mule Applications.
So, Non-Mule application is the right answer

D.   

GET, OPTIONS, HEAD

B.   CIDR blacks are used

E.   By default, HTTP requests can be made from the public internet to workers at port 6091

Explanation:
An Anypoint Virtual Private Cloud (VPC) provides a secure and private networking environment for MuleSoft applications, using specific architectural elements:

• CIDR Blocks
• Port 6091 for HTTP Requests
• Explanation of Correct Answers (B, E)
• Explanation of Incorrect Options
