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.

The implementation of a Process API must change.What is a valid approach that minimizes the impact of this change on API clients?
A.
Update the RAML definition of the current Process API and notify API client developers
by sending them links to the updated RAML definition
B.
Postpone changes until API consumers acknowledge they are ready to migrate to a new
Process API or API version
C.
Implement required changes to the Process API implementation so that whenever
possible, the Process API's RAML definition remains unchanged
D.
Implement the Process API changes in a new API implementation, and have the old API
implementation return an HTTP status code 301 - Moved Permanently to inform API clients
they should be calling the new API implementation
Implement required changes to the Process API implementation so that whenever
possible, the Process API's RAML definition remains unchanged
Explanation: Explanation
Correct Answer: Implement required changes to the Process API implementation so that,
whenever possible, the Process API’s RAML definition remains unchanged.
*****************************************
Key requirement in the question is:
>> Approach that minimizes the impact of this change on API clients
Based on above:
>> Updating the RAML definition would possibly impact the API clients if the changes
require any thing mandatory from client side. So, one should try to avoid doing that until
really necessary.
>> Implementing the changes as a completely different API and then redirectly the clients
with 3xx status code is really upsetting design and heavily impacts the API clients.
>> Organisations and IT cannot simply postpone the changes required until all API
consumers acknowledge they are ready to migrate to a new Process API or API version.
This is unrealistic and not possible.
The best way to handle the changes always is to implement required changes to the API
implementations so that, whenever possible, the API’s RAML definition remains
unchanged.
When can CloudHub Object Store v2 be used?
A. To store an unlimited number of key-value pairs
B. To store payloads with an average size greater than 15MB
C. To store information in Mule 4 Object Store v1
D. To store key-value pairs with keys up to 300 characters
Explanation: CloudHub Object Store v2 is a managed key-value store provided by
MuleSoft to support various use cases where temporary data storage is required. Here’s
why Option D is correct:
Key Length Support: Object Store v2 allows storage of keys with a length of up to
300 characters, making it suitable for applications needing flexible and descriptive
keys.
Limitations on Size:
Key-Value Limits: Object Store v2 is designed for moderate, transient storage
needs, and does not support unlimited storage. Thus, Option A is incorrect.
Backward Compatibility: Object Store v2 does not support Mule 4 applications
running Object Store v1. Option C is incorrect as Object Store v1 and v2 are
distinct.
Refer to the exhibit.

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 Anypoint Platform organization has been configured with an external identity provider (IdP) for identity management and client management. What credentials or token must be provided to Anypoint CLI to execute commands against the Anypoint Platform APIs?
A.
The credentials provided by the IdP for identity management
B.
The credentials provided by the IdP for client management
C.
An OAuth 2.0 token generated using the credentials provided by the IdP for client management
D.
An OAuth 2.0 token generated using the credentials provided by the IdP for identity management
The credentials provided by the IdP for identity management
Explanation: Explanation
Correct Answer: The credentials provided by the IdP for identity management
*****************************************
Reference: https://docs.mulesoft.com/runtime-manager/anypoint-platformcli#
authentication
>> There is no support for OAuth 2.0 tokens from client/identity providers to authenticate
via Anypoint CLI. Only possible tokens are "bearer tokens" that too only generated using
Anypoint Organization/Environment Client Id and Secret from
https://anypoint.mulesoft.com/accounts/login. Not the client credentials of client provider.
So, OAuth 2.0 is not possible. More over, the token is mainly for API Manager purposes
and not associated with a user. You can NOT use it to call most APIs (for example
Cloudhub and etc) as per this Mulesoft Knowledge article.
>> The other option allowed by Anypoint CLI is to use client credentials. It is possible to
use client credentials of a client provider but requires setting up Connected Apps in client
management but such details are not given in the scenario explained in the question.
>> So only option left is to use user credentials from identify provider
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.
