An API with multiple API implementations (Mule applications) is deployed to both CloudHub and customer-hosted Mule runtimes. All the deployments are managed by the MuleSoft-hosted control plane. An alert needs to be triggered whenever an API implementation stops responding to API requests, even if no API clients have called the API implementation for some time. What is the most effective out-of-the-box solution to create these alerts to monitor the API implementations?
A. Create monitors in Anypoint Functional Monitoring for the API implementations, where each monitor repeatedly invokes an API implementation endpoint
B. Add code to each API client to send an Anypoint Platform REST API request to generate a custom alert in Anypoint Platform when an API invocation times out
C. Handle API invocation exceptions within the calling API client and raise an alert from that API client when such an exception is thrown
D. Configure one Worker Not Responding alert.in Anypoint Runtime Manager for all API implementations that will then monitor every API implementation
Explanation:
In scenarios where multiple API implementations are deployed across
different environments (CloudHub and customer-hosted runtimes), Anypoint Functional
Monitoring is the most effective tool to monitor API availability and trigger alerts when an
API implementation becomes unresponsive. Here’s how it works:
A company deployed an API to a single worker/replica in the shared cloud in the U.S. West Region. What happens when the Availability Zone experiences an outage?
A. CloudHub will auto-redeploy the APL in the U.S. East Region
B. The APT will be unavailable until the availability comes back online, at which time the worker/replica will be auto-restarted
C. CloudHub will auto-redeploy the API in another Availability Zone in the U.S. West Region
D. The Anypoint Platform admin is alerted when the AP] is experiencing an outage and needs the trigger the CI/CD pipeline to redeploy to the US. East Region
Explanation:
In a CloudHub deployment with a single worker/replica located in a specific
Availability Zone (AZ), if an AZ experiences an outage, here’s what happens:
Worker Availability: Since the application is deployed in a single AZ, CloudHub
does not automatically redeploy the application in a different zone or region during
an outage. Thus, if the current AZ is unavailable, the application will be offline.
Auto-Restart upon AZ Recovery: Once the affected AZ is back online, CloudHub
will auto-restart the worker in the same AZ without manual intervention. This ensures that as soon as the AZ is functional, the application resumes
automatically.

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
An organization has built an application network following the API-led connectivity approach recommended by MuleSoft. To protect the application network against attacks from malicious external API clients, the organization plans to apply JSON Threat Protection policies. To which API-led connectivity layer should the JSON Threat Protection policies most commonly be applied?
A. All layers
B. System layer
C. Process layer
D. Experience layer
A large organization with an experienced central IT department is getting started using MuleSoft. There is a project to connect a siloed back-end system to a new Customer Relationship Management (CRM) system. The Center for Enablement is coaching them to use API-led connectivity. What action would support the creation of an application network using API-led connectivity?
A. Invite the business analyst to create a business process model to specify the canonical data model between the two systems
B. Determine if the new CRM system supports the creation of custom: REST APIs, establishes 4 private network with CloudHub, and supports GAuth 2.0 authentication
C. To expedite this project, central IT should extend the CRM system and back-end systems to connect to one another using built in integration interfaces
D. Create a System API to unlock the data on the back-end system using a REST API
Explanation:
For an organization starting with API-led connectivity to integrate a siloed
back-end system with a new CRM, the following approach aligns with best practices and
MuleSoft’s Center for Enablement (C4E) guidance:
API-led Connectivity: This model organizes APIs into distinct layers (System,
Process, and Experience) to improve reusability, modularity, and manageability.
What is a key performance indicator (KPI) that measures the success of a typical C4E that is immediately apparent in responses from the Anypoint Platform APIs?
A.
The number of production outage incidents reported in the last 24 hours
B.
The number of API implementations that have a publicly accessible HTTP endpoint and are being managed by Anypoint Platform
C.
The fraction of API implementations deployed manually relative to those deployed using a CI/CD tool
D.
The number of API specifications in RAML or OAS format published to Anypoint
Exchange
The number of API specifications in RAML or OAS format published to Anypoint
Exchange
Explanation: Explanation
Correct Answer: The number of API specifications in RAML or OAS format published to
Anypoint Exchange
*****************************************
>> The success of C4E always depends on their contribution to the number of reusable
assets that they have helped to build and publish to Anypoint Exchange.
>> It is NOT due to any factors w.r.t # of outages, Manual vs CI/CD deployments or
Publicly accessible HTTP endpoints
>> Anypoint Platform APIs helps us to quickly run and get the number of published
RAML/OAS assets to Anypoint Exchange. This clearly depicts how successful a C4E team
is based on number of returned assets in the response.

Traffic is routed through an API proxy to an API implementation. The API proxy is managed
by API Manager and the API implementation is deployed to a CloudHub VPC using
Runtime Manager. API policies have been applied to this API. In this deployment scenario,
at what point are the API policies enforced on incoming API client requests?
A.
At the API proxy
B.
At the API implementation
C.
At both the API proxy and the API implementation
D.
At a MuleSoft-hosted load balancer
At the API proxy
Explanation: Explanation
Correct Answer: At the API proxy
*****************************************
>> API Policies can be enforced at two places in Mule platform.
>> One - As an Embedded Policy enforcement in the same Mule Runtime where API
implementation is running.
>> Two - On an API Proxy sitting in front of the Mule Runtime where API implementation is
running.
>> As the deployment scenario in the question has API Proxy involved, the policies will be
enforced at the API Proxy.
Once an API Implementation is ready and the API is registered on API Manager, who should request the access to the API on Anypoint Exchange?
A.
None
B.
Both
C.
API Client
D.
API Consumer
API Consumer
Explanation: Explanation
Correct Answer: API Consumer
*****************************************
>> API clients are piece of code or programs that use the client credentials of API
consumer but does not directly interact with Anypoint Exchange to get the access
>> API consumer is the one who should get registered and request access to API and then
API client needs to use those client credentials to hit the APIs
So, API consumer is the one who needs to request access on the API from Anypoint
Exchange
