MuleSoft Certified Platform Architect - Level 1 Questions and Answers

Question 1

Options:

A.

OAuth 2.0 access token enforcement

B.

Client ID enforcement

C.

JSON threat protection

D.

IPwhitellst

Question 2

Which layer in the API-led connectivity focuses on unlocking key systems, legacy systems, data sources etc and exposes the functionality?

Options:

A.

Experience Layer

B.

Process Layer

C.

System Layer

Question 3

An API implementation is being designed that must invoke an Order API, which is known to repeatedly experience downtime.

For this reason, a fallback API is to be called when the Order API is unavailable.

What approach to designing the invocation of the fallback API provides the best resilience?

Options:

A.

Search Anypoint Exchange for a suitable existing fallback API, and then implement invocations to this fallback API in addition to the Order API

B.

Create a separate entry for the Order API in API Manager, and then invoke this API as a fallback API if the primary Order API is unavailable

C.

Redirect client requests through an HTTP 307 Temporary Redirect status code to the fallback API whenever the Order API is unavailable

D.

Set an option in the HTTP Requester component that invokes the Order API to instead invoke a fallback API whenever an HTTP 4xx or 5xx response status code is returned from the Order API

Question 4

The implementation of a Process API must change.

What is a valid approach that minimizes the impact of this change on API clients?

Options:

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

Question 5

A system API is deployed to a primary environment as well as to a disaster recovery (DR) environment, with different DNS names in each environment. A process API is a client to the system API and is being rate limited by the system API, with different limits in each of the environments. The system API's DR environment provides only 20% of the rate limiting offered by the primary environment. What is the best API fault-tolerant invocation strategy to reduce overall errors in the process API, given these conditions and constraints?

Options:

A.

Invoke the system API deployed to the primary environment; add timeout and retry logic to the process API to avoid intermittent failures; if it still fails, invoke the system API deployed to the DR environment

B.

Invoke the system API deployed to the primary environment; add retry logic to the process API to handle intermittent failures by invoking the system API deployed to the DR environment

C.

In parallel, invoke the system API deployed to the primary environment and the system API deployed to the DR environment; add timeout and retry logic to the process API to avoid intermittent failures; add logic to the process API to combine the results

D.

Invoke the system API deployed to the primary environment; add timeout and retry logic to the process API to avoid intermittent failures; if it still fails, invoke a copy of the process API deployed to the DR environment

Question 6

A Mule application exposes an HTTPS endpoint and is deployed to three CloudHub workers that do not use static IP addresses. The Mule application expects a high volume of client requests in short time periods. What is the most cost-effective infrastructure component that should be used to serve the high volume of client requests?

Options:

A.

A customer-hosted load balancer

B.

The CloudHub shared load balancer

C.

An API proxy

D.

Runtime Manager autoscaling

Question 7

When using CloudHub with the Shared Load Balancer, what is managed EXCLUSIVELY by the API implementation (the Mule application) and NOT by Anypoint Platform?

Options:

A.

The assignment of each HTTP request to a particular CloudHub worker

B.

The logging configuration that enables log entries to be visible in Runtime Manager

C.

The SSL certificates used by the API implementation to expose HTTPS endpoints

D.

The number of DNS entries allocated to the API implementation

Question 8

What is most likely NOT a characteristic of an integration test for a REST API implementation?

Options:

A.

The test needs all source and/or target systems configured and accessible

B.

The test runs immediately after the Mule application has been compiled and packaged

C.

The test is triggered by an external HTTP request

D.

The test prepares a known request payload and validates the response payload

Question 9

What are 4 important Platform Capabilities offered by Anypoint Platform?

Options:

A.

API Versioning, API Runtime Execution and Hosting, API Invocation, API Consumer Engagement

B.

API Design and Development, API Runtime Execution and Hosting, API Versioning, API Deprecation

C.

API Design and Development, API Runtime Execution and Hosting, API Operations and Management, API Consumer Engagement

D.

API Design and Development, API Deprecation, API Versioning, API Consumer Engagement

Question 10

What is typically NOT a function of the APIs created within the framework called API-led connectivity?

Options:

A.

They provide an additional layer of resilience on top of the underlying backend system, thereby insulating clients from extended failure of these systems.

B.

They allow for innovation at the user Interface level by consuming the underlying assets without being aware of how data Is being extracted from backend systems.

C.

They reduce the dependency on the underlying backend systems by helping unlock data from backend systems In a reusable and consumable way.

D.

They can compose data from various sources and combine them with orchestration logic to create higher level value.

Question 11

Refer to the exhibit.

Three business processes need to be implemented, and the implementations need to communicate with several different SaaS applications.

These processes are owned by separate (siloed) LOBs and are mainly independent of each other, but do share a few business entities. Each LOB has one development team and their own budget

In this organizational context, what is the most effective approach to choose the API data models for the APIs that will implement these business processes with minimal redundancy of the data models?

A) Build several Bounded Context Data Models that align with coherent parts of the business processes and the definitions of associated business entities

B) Build distinct data models for each API to follow established micro-services and Agile API-centric practices

C) Build all API data models using XML schema to drive consistency and reuse across the organization

D) Build one centralized Canonical Data Model (Enterprise Data Model) that unifies all the data types from all three business processes, ensuring the data model is consistent and non-redundant

Options:

A.

Option A

B.

Option B

C.

Option C

D.

Option D

Question 12

Refer to the exhibit.

A RAML definition has been proposed for a new Promotions Process API, and has been published to Anypoint Exchange.

The Marketing Department, who will be an important consumer of the Promotions API, has important requirements and expectations that must be met.

What is the most effective way to use Anypoint Platform features to involve the Marketing Department in this early API design phase?

A) Ask the Marketing Department to interact with a mocking implementation of the API using the automatically generated API Console

B) Organize a design workshop with the DBAs of the Marketing Department in which the database schema of the Marketing IT systems is translated into RAML

C) Use Anypoint Studio to Implement the API as a Mule application, then deploy that API implementation to CloudHub and ask the Marketing Department to interact with it

D) Export an integration test suite from API designer and have the Marketing Department execute the tests In that suite to ensure they pass

Option A

B.

Option B

C.

Option C

D.

Both

C.

API Client

D.

Question 14

When must an API implementation be deployed to an Anypoint VPC?

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
