An API client calls one method from an existing API implementation. The API
implementation is later updated. What change to the API implementation would require the API client's invocation logic to also be updated?
A.
When the data type of the response is changed for the method called by the API client
B.
When a new method is added to the resource used by the API client
C.
When a new required field is added to the method called by the API client
D.
When a child method is added to the method called by the API client
When a new required field is added to the method called by the API client
Explanation: Explanation
Correct Answer: When a new required field is added to the method called by the API client
*****************************************
>> Generally, the logic on API clients need to be updated when the API contract breaks.
>> When a new method or a child method is added to an API , the API client does not
break as it can still continue to use its existing method. So these two options are out.
>> We are left for two more where "datatype of the response if changed" and "a new
required field is added".
>> Changing the datatype of the response does break the API contract. However, the
question is insisting on the "invocation" logic and not about the response handling logic.
The API client can still invoke the API successfully and receive the response but the
response will have a different datatype for some field.
>> Adding a new required field will break the API's invocation contract. When adding a new
required field, the API contract breaks the RAML or API spec agreement that the API
client/API consumer and API provider has between them. So this requires the API client
invocation logic to also be updated.

4A developer for a transportation organization is implementing exactly one processing
functionality in a Reservation Mule application to process and store passenger
records. This Reservation application will be deployed to multiple CloudHub
workers/replicas. It is possible that several external systems could send duplicate
passenger records
to the Reservation application.
An appropriate storage mechanism must be selected to help the Reservation application
process each passenger record exactly once as much as possible. The selected storage
mechanism must be shared by all the CloudHub workers/replicas in order to synchronize
the state information to assist attempting exactly once processing of each passenger
record by the deployed Reservation Mule application.
Which type of simple storage mechanism in Anypoint Platform allows the Reservation Mule
application to update and share data between the CloudHub workers/replicas exactly
once, with minimal development effort?
A. Persistent Object Store
B. Runtime Fabric Object Store
C. Non-persistent Object Store
D. In-memory Mule Object Store

Correct Answer: Ask the Marketing Department to interact with a mocking implementation
of the API using the automatically generated API Console.
*****************************************
As per MuleSoft's IT Operating Model:
>> API consumers need NOT wait until the full API implementation is ready.
>> NO technical test-suites needs to be shared with end users to interact with APIs.
>> Anypoint Platform offers a mocking capability on all the published API specifications to
Anypoint Exchange which also will be rich in documentation covering all details of API
functionalities and working nature.
>> No needs of arranging days of workshops with end users for feedback.
API consumers can use Anypoint Exchange features on the platform and interact with the
API using its mocking feature. The feedback can be shared quickly on the same to
incorporate any changes.
A business process is being implemented within an organization's application network. The architecture group proposes using a more coarse-grained application network design with relatively fewer APIs deployed to the application network compared to a more fine-grained design. Overall, which factor typically increases with a more coarse-grained design for this business process implementation and deployment compared with using a more finegrained design?
A. The complexity of each API implementation
B. The number of discoverable assets related to APIs deployed in the application network
C. The number of possible connections between API implementations in the application network
D. The usage of network infrastructure resources by the application network
What is most likely NOT a characteristic of an integration test for a REST API
implementation?
A.
The test needs all source and/or target systems configured and accessible
B.
The test runs immediately after the Mule application has been compiled and packaged
C.
The test is triggered by an external HTTP request
D.
The test prepares a known request payload and validates the response payload
The test runs immediately after the Mule application has been compiled and packaged
Explanation: Explanation
Correct Answer: The test runs immediately after the Mule application has been compiled
and packaged
*****************************************
>> Integration tests are the last layer of tests we need to add to be fully covered.
>> These tests actually run against Mule running with your full configuration in place and are tested from external source as they work in PROD.
>> These tests exercise the application as a whole with actual transports enabled. So,
external systems are affected when these tests run.
So, these tests do NOT run immediately after the Mule application has been compiled and
packaged.
FYI... Unit Tests are the one that run immediately after the Mule application has been
compiled and packaged.

Correct Answer: XML over HTTP
*****************************************
>> API-led connectivity and Application Networks urge to have the APIs on HTTP based
protocols for building most effective APIs and networks on top of them.
>> The HTTP based APIs allow the platform to apply various varities of policies to address
many NFRs
>> The HTTP based APIs also allow to implement many standard and effective
implementation patterns that adhere to HTTP based w3c rules
A European company has customers all across Europe, and the IT department is migrating from an older platform to MuleSoft. The main requirements are that the new platform should allow redeployments with zero downtime and deployment of applications to multiple runtime versions, provide security and speed, and utilize Anypoint MQ as the message service. Which runtime plane should the company select based on the requirements without additional network configuration?
A. Runtime Fabric on VMs / Bare Metal for the runtime plane
B. Customer-hosted runtime plane
C. MuleSoft-hosted runtime plane (CloudHub)
D. Anypoint Runtime Fabric on Self-Managed Kubernetes for the runtime plane
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:
