what is true when using customer-hosted Mule runtimes with the MuleSoft-hosted Anypoint Platform control plane (hybrid deployment)?
A.
Anypoint Runtime Manager initiates a network connection to a Mule runtime in order to deploy Mule applications
B.
The MuleSoft-hosted Shared Load Balancer can be used to load balance API
invocations to the Mule runtimes
C.
API implementations can run successfully in customer-hosted Mule runtimes, even when they are unable to communicate with the control plane
D.
Anypoint Runtime Manager automatically ensures HA in the control plane by creating a new Mule runtime instance in case of a node failure
API implementations can run successfully in customer-hosted Mule runtimes, even when they are unable to communicate with the control plane
Explanation: Explanation
Correct Answer: API implementations can run successfully in customer-hosted Mule
runtimes, even when they are unable to communicate with the control plane.
*****************************************
>> We CANNOT use Shared Load balancer to load balance APIs on customer hosted
runtimes
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
Explanation:
To accommodate the new requirement of allowing updates to existing
quotes, the following actions should be taken:
Which statement is true about identity management and client management on Anypoint Platform?
A. If an external identity provider is configured, the SAML 2.0 bearer tokens issued by the identity provider cannot be used for invocations of the Anypoint Platform web APIs
B. If an external client provider is configured, it must be configured at the Anypoint Platform organization level and cannot be assigned to individual business groups and environments
C. Anypoint Platform supports configuring one external identity provider
D. Both client management and identity management require an identity provider
Explanation:
Anypoint Platform allows organizations to integrate one external identity
provider (IdP) for identity and access management (IAM), supporting SSO and centralized
user authentication.
What do the API invocation metrics provided by Anypoint Platform provide?
A.
ROI metrics from APIs that can be directly shared with business users
B.
Measurements of the effectiveness of the application network based on the level of reuse
C.
Data on past API invocations to help identify anomalies and usage patterns across various APIs
D.
Proactive identification of likely future policy violations that exceed a given threat
threshold
Data on past API invocations to help identify anomalies and usage patterns across various APIs
Explanation: Explanation
Correct Answer: Data on past API invocations to help identify anomalies and usage
patterns across various APIs
*****************************************
API Invocation metrics provided by Anypoint Platform:
>> Does NOT provide any Return Of Investment (ROI) related information. So the option
suggesting it is OUT.
>> Does NOT provide any information w.r.t how APIs are reused, whether there is effective
usage of APIs or not etc...
>> Does NOT prodive any prediction information as such to help us proactively identify any
future policy violations.
So, the kind of data/information we can get from such metrics is on past API invocations to
help identify anomalies and usage patterns across various APIs.

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.
Integration tests
B.
Performance tests
C.
Functional tests (Blackbox)
D.
Unit tests (Whitebox)
Unit tests (Whitebox)
Explanation: Explanation
Correct Answer: Unit tests (Whitebox)
*****************************************
Reference: https://docs.mulesoft.com/mule-runtime/3.9/testing-strategies
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
An API experiences a high rate of client requests (TPS) vwth small message paytoads.
How can usage limits be imposed on the API based on the type of client application?
A.
Use an SLA-based rate limiting policy and assign a client application to a matching SLA
tier based on its type
B.
Use a spike control policy that limits the number of requests for each client application
type
C.
Use a cross-origin resource sharing (CORS) policy to limit resource sharing between
client applications, configured by the client application type
D.
Use a rate limiting policy and a client ID enforcement policy, each configured by the
client application type
Use an SLA-based rate limiting policy and assign a client application to a matching SLA
tier based on its type
Explanation: Correct Answer: Use an SLA-based rate limiting policy and assign a client
application to a matching SLA tier based on its type.
*****************************************
>> SLA tiers will come into play whenever any limits to be imposed on APIs based on client
type

policies
When must an API implementation be deployed to an Anypoint VPC?
A.
When the API Implementation must invoke publicly exposed services that are deployed outside of CloudHub in a customer- managed AWS instance
B.
When the API implementation must be accessible within a subnet of a restricted customer-hosted network that does not allow public access
C.
When the API implementation must be deployed to a production AWS VPC using the Mule Maven plugin
D.
When the API Implementation must write to a persistent Object Store
When the API Implementation must invoke publicly exposed services that are deployed outside of CloudHub in a customer- managed AWS instance
In which layer of API-led connectivity, does the business logic orchestration reside?
A.
System Layer
B.
Experience Layer
C.
Process Layer
Process Layer
Explanation: Explanation
Correct Answer: Process Layer
*****************************************
>> Experience layer is dedicated for enrichment of end user experience. This layer is to
meet the needs of different API clients/ consumers.
>> System layer is dedicated to APIs which are modular in nature and implement/ expose
various individual functionalities of backend systems
>> Process layer is the place where simple or complex business orchestration logic is
written by invoking one or many System layer modular APIs
So, Process Layer is the right answer.
