An online store's marketing team has noticed an increase in customers leaving online baskets without checking out. They suspect a technology issue is at the root cause of the baskets being left behind. They approach the Center for Enablement to ask for help identifying the issue. Multiple APIs from across all the layers of their application network are involved in the shopping application. Which feature of the Anypoint Platform can be used to view metrics from all involved APIs at the same time?


A. Custom dashboards


B. Built-in dashboards


C. Functional monitoring


D. API Manager





B.
  Built-in dashboards

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 A


B. Option B


C. Option C


D. Option D





A.
  Option A

Explanation:

  • Correct Answer: Build several Bounded Context Data Models that align with coherent parts of the business processes and the definitions of associated business entities.
  • The options w.r.t building API data models using XML schema/ Agile API-centric practices are irrelevant to the scenario given in the question. So these two are INVALID.
  • Building EDM (Enterprise Data Model) is not feasible or right fit for this scenario as the teams and LOBs work in silo and they all have different initiatives, budget etc.. Building EDM needs intensive coordination among all the team which evidently seems not possible in this scenario.
So, the right fit for this scenario is to build several Bounded Context Data Models that align with coherent parts of the business processes and the definitions of associated business entities.

Which of the following best fits the definition of API-led connectivity?


A.

API-led connectivity is not just an architecture or technology but also a way to organize people and processes for efficient IT delivery in the organization


B.

API-led connectivity is a 3-layered architecture covering Experience, Process and System layers


C.

API-led connectivity is a technology which enabled us to implement Experience, Process and System layer based APIs





A.
  

API-led connectivity is not just an architecture or technology but also a way to organize people and processes for efficient IT delivery in the organization



Explanation: Explanation
Correct Answer: API-led connectivity is not just an architecture or technology but also a
way to organize people and processes for efficient IT delivery in the organization.

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





D.
  

The remaining capacity allowed by the API implementation



Explanation: Explanation

A company is building an application network using MuleSoft's recommendations for various API layers. What is the main (default) role of a process API in an application network?


A. To secure and optimize the data synchronization processing of large data dumps between back-end systems


B. To manage and process the secure direct communication between a back-end system and an end-user client of mobile device in the application network


C. To automate parts of business processes by coordinating and orchestrating the invocation of other APIs in the application network


D. To secure, Manage, and process communication with specific types of end-user client applications or devices in the application network





C.
  To automate parts of business processes by coordinating and orchestrating the invocation of other APIs in the application network

Explanation:

  • Role of Process API in API-led Connectivity:
  • Evaluating the Options:
Conclusion:
Refer to MuleSoft's API-led connectivity documentation for further explanation of the roles and responsibilities of Process APIs in an application network.

An API implementation is deployed on a single worker on CloudHub and invoked by
external API clients (outside of CloudHub). How can an alert be set up that is guaranteed to
trigger AS SOON AS that API implementation stops responding to API invocations?


A.

Implement a heartbeat/health check within the API and invoke it from outside the Anypoint Platform and alert when the heartbeat does not respond


B.

Configure a "worker not responding" alert in Anypoint Runtime Manager 


C.

Handle API invocation exceptions within the calling API client and raise an alert from that API client when the API Is unavailable


D.

Create an alert for when the API receives no requests within a specified time period





B.
  

Configure a "worker not responding" alert in Anypoint Runtime Manager 



Explanation: Explanation
Correct Answer: Configure a “Worker not responding” alert in Anypoint Runtime Manager.
*****************************************
>> All the options eventually helps to generate the alert required when the application stops
responding.
>> However, handling exceptions within calling API and then raising alert from API client is
inappropriate and silly. There could be many API clients invoking the API implementation
and it is not ideal to have this setup consistently in all of them. Not a realistic way to do.
>> Implementing a health check/ heartbeat with in the API and calling from outside to
detmine the health sounds OK but needs extra setup for it and same time there are very
good chances of generating false alarms when there are any intermittent network issues
between external tool calling the health check API on API implementation. The API
implementation itself may not have any issues but due to some other factors some false
alarms may go out.
>> Creating an alert in API Manager when the API receives no requests within a specified
time period would actually generate realistic alerts but even here some false alarms may
go out when there are genuinely no requests from API clients.
The best and right way to achieve this requirement is to setup an alert on Runtime
Manager with a condition "Worker not responding". This would generate an alert
AS SOON AS the workers become unresponsive.


An existing Quoting API is defined in RAML and used by REST clients for interacting with the quoting engine. Currently there is a resource defined in the RAML that allows the creation of quotes; however, a new requirement was just received to allow for the updating of existing quotes. Which two actions need to be taken to facilitate this change so it can be processed? (Choose 2 answers)


A. Update the API implementation to accommodate the new update request


B. B. Remove the old client applications and create new client applications to account for the changes


C. Update the RAML with new method details for the update request


D. Deprecate existing versions of the API in Exchange


E. Add a new API policy to API Manager to allow access to the updated endpoint





A.
  Update the API implementation to accommodate the new update request

C.
  Update the RAML with new method details for the update request

Explanation:
To accommodate the new requirement of allowing updates to existing quotes, the following actions should be taken:

  • Update the RAML Definition (Option C):
  • Update the API Implementation (Option A):
  • Explanation of Incorrect Options:

Which component monitors APIs and endpoints at scheduled intervals, receives reports about whether tests pass or fail, and displays statistics about API and endpoint performance?

  APT Functional Monitoring

Explanation:

  • Understanding API Functional Monitoring:
  • Component Features:
