An organization is deploying their new implementation of the OrderStatus System API to
multiple workers in CloudHub. This API fronts the organization's on-premises Order
Management System, which is accessed by the API implementation over an IPsec tunnel.
What type of error typically does NOT result in a service outage of the OrderStatus System
API?


A.

A CloudHub worker fails with an out-of-memory exception


B.

API Manager has an extended outage during the initial deployment of the API
implementation


C.

The AWS region goes offline with a major network failure to the relevant AWS data centers


D.

The Order Management System is Inaccessible due to a network outage in the
organization's on-premises data center





A.
  

A CloudHub worker fails with an out-of-memory exception



Explanation: Explanation
Correct Answer: A CloudHub worker fails with an out-of-memory exception.
*****************************************
>> An AWS Region itself going down will definitely result in an outage as it does not matter
how many workers are assigned to the Mule App as all of those in that region will go down.
This is a complete downtime and outage.
>> Extended outage of API manager during initial deployment of API implementation will of
course cause issues in proper application startup itself as the API Autodiscovery might fail
or API policy templates and polices may not be downloaded to embed at the time of
applicaiton startup etc... there are many reasons that could cause issues.
>> A network outage onpremises would of course cause the Order Management System
not accessible and it does not matter how many workers are assigned to the app they all
will fail and cause outage for sure.
The only option that does NOT result in a service outage is if a cloudhub worker fails with
an out-of-memory exception. Even if a worker fails and goes down, there are still other
workers to handle the requests and keep the API UP and Running. So, this is the right
answer.

An API has been updated in Anypoint Exchange by its API producer from version 3.1.1 to
3.2.0 following accepted semantic versioning practices and the changes have been
communicated via the API's public portal.
The API endpoint does NOT change in the new version.
How should the developer of an API client respond to this change?


A.

The update should be identified as a project risk and full regression testing of the functionality that uses this API should be run


B.

The API producer should be contacted to understand the change to existing functionality


C.

The API producer should be requested to run the old version in parallel with the new one


D.

The API client code ONLY needs to be changed if it needs to take advantage of new
features





D.
  

The API client code ONLY needs to be changed if it needs to take advantage of new
features

What is the best way to decompose one end-to-end business process into a collaboration of Experience, Process, and System APIs?
A) Handle customizations for the end-user application at the Process API level rather than the Experience API level
B) Allow System APIs to return data that is NOT currently required by the identified Process or Experience APIs
C) Always use a tiered approach by creating exactly one API for each of the 3 layers (Experience, Process and System APIs)
D) Use a Process API to orchestrate calls to multiple System APIs, but NOT to other Process APIs


A. Option A


B. Option B


C. Option C


D. Option D





B.
  Option B

Explanation:
Correct Answer: Allow System APIs to return data that is NOT currently required by the identified Process or Experience APIs.

  • All customizations for the end-user application should be handled in "Experience API" only. Not in Process API
  • We should use tiered approach but NOT always by creating exactly one API for each of the 3 layers. Experience APIs might be one but Process APIs and System APIs are often more than one. System APIs for sure will be more than one all the time as they are the smallest modular APIs built in front of end systems.
  • Process APIs can call System APIs as well as other Process APIs. There is no such anti-design pattern in API-Led connectivity saying Process APIs should not call other Process APIs.
So, the right answer in the given set of options that makes sense as per API-Led connectivity principles is to allow System APIs to return data that is NOT currently required by the identified Process or Experience APIs. This way, some future Process APIs can make use of that data from System APIs and we need NOT touch the System layer APIs again and again.

A company wants to move its Mule API implementations into production as quickly as
possible. To protect access to all Mule application data and metadata, the company
requires that all Mule applications be deployed to the company's customer-hosted
infrastructure within the corporate firewall. What combination of runtime plane and control
plane options meets these project lifecycle goals?


A.

Manually provisioned customer-hosted runtime plane and customer-hosted control plane


B.

MuleSoft-hosted runtime plane and customer-hosted control plane


C.

Manually provisioned customer-hosted runtime plane and MuleSoft-hosted control plane


D.

iPaaS provisioned customer-hosted runtime plane and MuleSoft-hosted control plane





A.
  

Manually provisioned customer-hosted runtime plane and customer-hosted control plane



Explanation:
Explanation
Correct Answer: Manually provisioned customer-hosted runtime plane and customerhosted
control plane
*****************************************
There are two key factors that are to be taken into consideration from the scenario given in
the question.
>> Company requires both data and metadata to be resided within the corporate firewall
>> Company would like to go with customer-hosted infrastructure.
Any deployment model that is to deal with the cloud directly or indirectly (Mulesoft-hosted
or Customer's own cloud like Azure, AWS) will have to share atleast the metadata.
Application data can be controlled inside firewall by having Mule Runtimes on customer
hosted runtime plane. But if we go with Mulsoft-hosted/ Cloud-based control plane, the
control plane required atleast some minimum level of metadata to be sent outside the
corporate firewall.
As the customer requirement is pretty clear about the data and metadata both to be within
the corporate firewall, even though customer wants to move to production as quickly as
possible, unfortunately due to the nature of their security requirements, they have no other
option but to go with manually provisioned customer-hosted runtime plane and customerhosted
control plane.

Which of the below, when used together, makes the IT Operational Model effective?


A.

C.

Create resuable assets, make them discoverable so that LOB teams can self-serve and browse the APIs





C.
  

Create resuable assets, make them discoverable so that LOB teams can self-serve and browse the APIs



Explanation: Explanation
Correct Answer: Create reusable assets, Make them discoverable so that LOB teams can self-serve and browse the APIs, Get active feedback and usage metrics.
