Due to a limitation in the backend system, a system API can only handle up to 500
requests per second. What is the best type of API policy to apply to the system API to avoid overloading the backend system?
A.
Rate limiting
B.
HTTP caching
C.
Rate limiting - SLA based
D.
Spike control
Spike control
Explanation: Explanation
Correct Answer: Spike control
*****************************************
>> First things first, HTTP Caching policy is for purposes different than avoiding the
backend system from overloading. So this is OUT.
>> Rate Limiting and Throttling/ Spike Control policies are designed to limit API access, but
have different intentions.
>> Rate limiting protects an API by applying a hard limit on its access.
>> Throttling/ Spike Control shapes API access by smoothing spikes in traffic.
That is why, Spike Control is the right option
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.
A Platform Architect inherits a legacy monolithic SOAP-based web service that performs a number of tasks, including showing all policies belonging to a client. The service connects to two back-end systems — a life-insurance administration system and a general-insurance administration system — and then queries for insurance policy information within each system, aggregates the results, and presents a SOAP-based response to a user interface (UI). The architect wants to break up the monolithic web service to follow API-led conventions. Which part of the service should be put into the process layer?
A. Combining the insurance policy information from the administration systems
B. Presenting the SOAP-based response to the UI
C. Authenticating and maintaining connections to each of the back-end administration systems
D. Querying the data from the administration systems
Explanation:
In the API-led connectivity approach, each layer (System, Process, and
Experience) has a distinct purpose:
An organization wants to create a Center for Enablement (C4E). The IT director schedules a series of meetings with IT senior managers. What should be on the agenda of the first meeting?
A. Define C4E objectives, mission statement, guiding principles, a
B. Explore API monetization options based on identified use cases through MuleSoft
C. A walk through of common-services best practices for logging, auditing, exception handling, caching, security via policy, and rate limiting/throttling via policy
D. Specify operating model for the MuleSoft Integrations division
Explanation:
In the initial meeting for establishing a Center for Enablement (C4E), it’s
essential to lay the foundational vision, objectives, and guiding principles for the team.
Here’s why this is crucial:
What is the main change to the IT operating model that MuleSoft recommends to
organizations to improve innovation and clock speed?
A.
Drive consumption as much as production of assets; this enables developers to discover
and reuse assets from other projects and encourages standardization
B.
Expose assets using a Master Data Management (MDM) system; this standardizes
projects and enables developers to quickly discover and reuse assets from other projects
C.
Implement SOA for reusable APIs to focus on production over consumption; this
standardizes on XML and WSDL formats to speed up decision making
D.
Create a lean and agile organization that makes many small decisions everyday; this
speeds up decision making and enables each line of business to take ownership of its
projects
Drive consumption as much as production of assets; this enables developers to discover
and reuse assets from other projects and encourages standardization
Explanation: Explanation
Correct Answer: Drive consumption as much as production of assets; this enables
developers to discover and reuse assets from other projects and encourages
standardization
*****************************************
>> The main motto of the new IT Operating Model that MuleSoft recommends and made
popular is to change the way that they are delivered from a production model to a
production + consumption model, which is done through an API strategy called API-led
connectivity.
>> The assets built should also be discoverable and self-serveable for reusablity across
LOBs and organization.
>> MuleSoft's IT operating model does not talk about SDLC model (Agile/ Lean etc) or
MDM at all. So, options suggesting these are not valid.

The asset version 2.0.0 of the Order API is successfully published in Exchange and configured in API Manager with the Autodiscovery API ID correctly linked to the API implementation, A new GET method is added to the existing API specification, and after updates, the asset version of the Order API is 2.0.1. What happens to the Autodiscovery API ID when the new asset version is updated in API Manager?
A. The API ID changes, but no changes are needed to the API implementation for the new asset version in the API Autediscovery global element because the API ID is automatically updated
B. The APL ID changes, so the API implementation must be updated with the latest API ID for the new asset version in the API Autodiscovery global element
C. The APLID does not change, so no changes to the APT implementation are needed for the new asset version in the API Autodiscovery global element
D. The APL ID does not change, but the API implementation must be updated in the AP] Autodiscovery global element to indicate the new asset version 2.0.4

A circuit breaker strategy is planned in order to meet the goal of improved response time
and demand on a downstream API.
A. Create a custom policy that implements the circuit breaker and includes policy template expressions for the required settings
B. Create Anypoint Monitoring alerts for Circuit Open/Closed configurations, and then implement a retry strategy for Circuit Half-Open configuration
C. Add the Circuit Breaker policy to the API instance, and configure the required settings
D. Implement the strategy in a Mule application, and provide the settings in the YAML configuration
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 APIs 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 API producer should be requested to run the old version in parallel with the new one
B.
The API producer should be contacted to understand the change to existing functionality
C.
The API client code only needs to be changed if it needs to take advantage of the new features
D.
The API clients need to update the code on their side and need to do full regression
The API client code only needs to be changed if it needs to take advantage of the new features
