MCPA-Level-1-Maintenance Exam Training Practice Tests (MuleSoft Certified Platform Architect

Question 1

What is a best practice when building System APIs?

A. Model all API resources and methods to closely mimic the operations of the backend system B. Build an Enterprise Data Model (Canonical Data Model) for each backend system and apply it to System APIs C. Expose to API clients all technical details of the API implementation's interaction wifch the backend system D. Document the API using an easily consumable asset like a RAML definition

Question 2

A system API has a guaranteed SLA of 100 ms per request. The system API is deployed to a primary environment as well as to a disaster recovery (DR) environment, with different DNS names in each environment. An upstream process API invokes the system API and the main goal of this process API is to respond to client requests in the least possible time. In what order should the system APIs be invoked, and what changes should be made in order to speed up the response time for requests from the process API?

A. Invoke ONLY the system API deployed to the primary environment, and add timeout and retry logic to avoid intermittent failures B. In parallel, invoke the system API deployed to the primary environment and the system API deployed to the DR environment, and ONLY use the first response C. Invoke the system API deployed to the primary environment, and if it fails, invoke the system API deployed to the DR environment D. In parallel, invoke the system API deployed to the primary environment and the system API deployed to the DR environment using a scatter-gather configured with a timeout, and then merge the responses

Question 3

What Mule application can have API policies applied by
Anypoint Platform to the endpoint exposed by that Mule application?
A) A Mule application that accepts requests over HTTP/1.x

B) A Mule application that accepts JSON requests over TCP but is NOT required to provide a response

C) A Mute application that accepts JSON requests over WebSocket

D) A Mule application that accepts gRPC requests over HTTP/2

A. Option D B. Option B C. Option A D. Option C

Question 4

True or False. We should always make sure that the APIs being designed and developed are self-servable even if it needs more man-day effort and resources.

Question 5

Question 10: Skipped
An API implementation returns three X-RateLimit-* HTTP response headers to a requesting API client. What type of information do these response headers indicate to the API client?

A. The error codes that result from throttling B. A correlation ID that should be sent in the next request C. The HTTP response size D. The remaining capacity allowed by the API implementation

Question 6

A company uses a hybrid Anypoint Platform deployment model that combines the EU control plane with customer-hosted Mule runtimes. After successfully testing a Mule API implementation in the Staging environment, the Mule API implementation is set with environment-specific properties and must be promoted to the Production environment. What is a way that MuleSoft recommends to configure the Mule API implementation and automate its promotion to the Production environment?

A. Bundle properties files for each environment into the Mule API implementation's deployable archive, then promote the Mule API implementation to the Production environment using Anypoint CLI or the Anypoint Platform REST APIsB. B. Modify the Mule API implementation's properties in the API Manager Properties tab, then promote the Mule API implementation to the Production environment using API Manager C. Use an API policy to change properties in the Mule API implementation deployed to the Staging environment and another API policy to deploy the Mule API implementation to the Production environment D. Modify the Mule API implementation's properties in Anypoint Exchange, then promote the Mule API implementation to the Production environment using Runtime Manager

Question 7

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

A. Option D B. Option B C. Option A D. Option C

Question 8

What are the major benefits of MuleSoft proposed IT Operating Model?

A. 1. Decrease the IT delivery gap
2. Meet various business demands by increasing the IT capacity and forming various IT departments
3. Make consumption of assets at the rate of production B. 1. Decrease the IT delivery gap
2. Meet various business demands without increasing the IT capacity
3. Focus on creation of reusable assets first. Upon finishing creation of all the possible assets then inform the LOBs in the organization to start using them C. 1. Decrease the IT delivery gap
2. Meet various business demands without increasing the IT capacity
3. Make consumption of assets at the rate of production

Question 9

An organization is deploying their new implementation of the OrderStatus System API to multiple workers in CloudHub. This API fronts the organization's on-premises Order Management System, which is accessed by the API implementation over an IPsec tunnel.
What type of error typically does NOT result in a service outage of the OrderStatus System API?

A. The Order Management System is Inaccessible due to a network outage in the organization's on-premises data center B. API Manager has an extended outage during the initial deployment of the API implementation C. A CloudHub worker fails with an out-of-memory exception D. The AWS region goes offline with a major network failure to the relevant AWS data centers
