NEW QUESTION # 30
A company has started to create an application network and is now planning to implement a Center for Enablement (C4E) organizational model. What key factor would lead the company to decide upon a federated rather than a centralized C4E?
- A. When various teams responsible for creating APIs are new to integration and hence need extensive training
- B. When the majority of the applications in the application network are cloud based
- C. When development is already organized into several independent initiatives or groups
- D. When there are a large number of existing common assets shared by development teams
Answer: C
Explanation:
Correct answer: When development is already organized into several independent initiatives or groups
*****************************************
>> It would require lot of process effort in an organization to have a single C4E team coordinating with multiple already organized development teams which are into several independent initiatives. A single C4E works well with different teams having at least a common initiative. So, in this scenario, federated C4E works well instead of centralized C4E.
NEW QUESTION # 31
Refer to the exhibit.
Three business processes need to be implemented, and the implementations need to communicate with several different SaaS applications.
These processes are owned by separate (siloed) LOBs and are mainly independent of each other, but do share a few business entities. Each LOB has one development team and their own budget In this organizational context, what is the most effective approach to choose the API data models for the APIs that will implement these business processes with minimal redundancy of the data models?
A) Build several Bounded Context Data Models that align with coherent parts of the business processes and the definitions of associated business entities
B) Build distinct data models for each API to follow established micro-services and Agile API-centric practices
C) Build all API data models using XML schema to drive consistency and reuse across the organization
D) Build one centralized Canonical Data Model (Enterprise Data Model) that unifies all the data types from all three business processes, ensuring the data model is consistent and non-redundant
- A. Option B
- B. Option C
- C. Option A
- D. Option D
Answer: B
NEW QUESTION # 32

The API endpoint does NOT change in the new version. How should the developer of an API client respond to this change?
- A. The API producer should be requested to run the old version in parallel with the new one
- B. The API client code only needs to be changed if it needs to take advantage of the new features
- C. The API producer should be contacted to understand the change to existing functionality
- D. The API clients need to update the code on their side and need to do full regression
Answer: B
NEW QUESTION # 33

How are CloudHub workers assigned to availability zones (AZs) when the organization's Mule applications are deployed to CloudHub in that region?
- A. AZs are selected as part of the Mule application's deployment configuration
- B. Workers belonging to a given environment are assigned to the same AZ within that region
- C. An AZ is randomly selected for a Mule application, and all the Mule application's CloudHub workers are assigned to that one AZ

Answer: C
NEW QUESTION # 34
A new upstream API Is being designed to offer an SLA of 500 ms median and 800 ms maximum (99th percentile) response time. The corresponding API implementation needs to sequentially invoke 3 downstream APIs of very similar complexity.
The first of these downstream APIs offers the following SLA for its response time: median: 100 ms, 80th percentile: 500 ms, 95th percentile: 1000 ms.
If possible, how can a timeout be set in the upstream API for the invocation of the first downstream API to meet the new upstream API's desired SLA?
- A. No timeout is possible to meet the upstream API's desired SLA; a different SLA must be negotiated with the first downstream API or invoke an alternative API
- B. Set a timeout of 50 ms; this times out more invocations of that API but gives additional room for retries
- C. Do not set a timeout; the Invocation of this API Is mandatory and so we must wait until it responds
- D. Set a timeout of 100 ms; that leaves 400 ms for the other two downstream APIs to complete
Answer: D
NEW QUESTION # 35
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 prepares a known request payload and validates the response payload
- D. The test is triggered by an external HTTP request
Answer: B
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.
NEW QUESTION # 36
A set of tests must be performed prior to deploying API implementations to a staging environment. Due to data security and access restrictions, untested APIs cannot be granted access to the backend systems, so instead mocked data must be used for these tests. The amount of available mocked data and its contents is sufficient to entirely test the API implementations with no active connections to the backend systems. What type of tests should be used to incorporate this mocked data?
- A. Performance tests
- B. Functional tests (Blackbox)
- C. Unit tests (Whitebox)
- D. Integration tests
Answer: C
Explanation:
Correct answer: Unit tests (Whitebox)
*****************************************
Reference:
As per general IT testing practice and MuleSoft recommended practice, Integration and Performance tests should be done on full end to end setup for right evaluation. Which means all end systems should be connected while doing the tests. So, these options are OUT and we are left with Unit Tests and Functional Tests.
As per attached reference documentation from MuleSoft:
Unit Tests - are limited to the code that can be realistically exercised without the need to run it inside Mule itself. So good candidates are Small pieces of modular code, Sub Flows, Custom transformers, Custom components, Custom expression evaluators etc.
Functional Tests - are those that most extensively exercise your application configuration. In these tests, you have the freedom and tools for simulating happy and unhappy paths. You also have the possibility to create stubs for target services and make them success or fail to easily simulate happy and unhappy paths respectively.
As the scenario in the question demands for API implementation to be tested before deployment to Staging and also clearly indicates that there is enough/ sufficient amount of mock data to test the various components of API implementations with no active connections to the backend systems, Unit Tests are the one to be used to incorporate this mocked data.
NEW QUESTION # 37
What is typically NOT a function of the APIs created within the framework called API-led connectivity?
- A. They allow for innovation at the user Interface level by consuming the underlying assets without being aware of how data Is being extracted from backend systems.
- B. They reduce the dependency on the underlying backend systems by helping unlock data from backend systems In a reusable and consumable way.
- C. They can compose data from various sources and combine them with orchestration logic to create higher level value.
- D. They provide an additional layer of resilience on top of the underlying backend system, thereby insulating clients from extended failure of these systems.

- B. Always use a tiered approach by creating exactly one API for each of the 3 layers (Experience, Process and System APIs).
- C. Handle customizations for the end-user application at the Process API level rather than the Experience API level.
- D. Allow System APIs to return data that is NOT currently required by the identified Process or Experience APIs.

- A. When the API receives a very high number of API invocations
- B. When the response time of API invocations exceeds a threshold
- C. When the API is invoked by an unrecognized API client
- D. When a particular API client invokes the API too often within a given time period
