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
A customer has an ELA contract with MuleSoft. An API deployed to CloudHub is consistently experiencing performance issues. Based on the root cause analysis, it is determined that autoscaling needs to be applied. How can this be achieved?
A. Configure a policy so that when the number of HTTP requests reaches a certain threshold the number of workers/replicas increases (horizontal scaling)
B. Configure two separate policies: When CPU and memory reach certain threshold, increase the worker/replica type (vertical sealing) and the number of workers/replicas (horizontal sealing)
C. Configure a policy based on CPU usage so that CloudHub auto-adjusts the number of workers/replicas (horizontal scaling)
D. Configure a policy so that when the response time reaches a certain threshold the worker/replica type increases (vertical scaling)
Explanation:
In MuleSoft CloudHub, autoscaling is essential to managing application load
efficiently. CloudHub supports horizontal scaling based on CPU usage, which is wellsuited
to applications experiencing variable demand and needing responsive resource
allocation.

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.
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.
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.

How are an API implementation, API client, and API consumer combined to invoke and process an API?
A.
The API consumer creates an API implementation, which receives API invocations from
an API such that they are processed for an API client
B.
The API client creates an API consumer, which receives API invocations from an API such that they are processed for an API implementation
C.
The ApI consumer creates an API client, which sends API invocations to an API such that they are processed by an API implementation
D.
The ApI client creates an API consumer, which sends API invocations to an API such that they are processed by an API implementation
The ApI consumer creates an API client, which sends API invocations to an API such that they are processed by an API implementation
Explanation:
Explanation
Correct Answer: The API consumer creates an API client, which sends API invocations to
an API such that they are processed by an API implementation
*****************************************
Terminology:
>> API Client - It is a piece of code or program the is written to invoke an API
>> API Consumer - An owner/entity who owns the API Client. API Consumers write API
clients.
>> API - The provider of the API functionality. Typically an API Instance on API Manager
where they are managed and operated.
>> API Implementation - The actual piece of code written by API provider where the
functionality of the API is implemented. Typically, these are Mule Applications running on
Runtime Manager.
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
