Free and Premium MuleSoft MCPA-Level-1-Maintenance Dumps Questions Answers

MuleSoft Certified Platform Architect - Level 1 MAINTENANCE Questions and Answers

Question 1

Refer to the exhibit.

what is true when using customer-hosted Mule runtimes with the MuleSoft-hosted Anypoint Platform control plane (hybrid deployment)?

Options:

A.

Anypoint Runtime Manager initiates a network connection to a Mule runtime in order to deploy Mule applications

B.

The MuleSoft-hosted Shared Load Balancer can be used to load balance API invocations to the Mule runtimes

C.

API implementations can run successfully in customer-hosted Mule runtimes, even when they are unable to communicate with the control plane

D.

Anypoint Runtime Manager automatically ensures HA in the control plane by creating a new Mule runtime instance in case of a node failure

Question 2

How can the application of a rate limiting API policy be accurately reflected in the RAML definition of an API?

Options:

A.

By refining the resource definitions by adding a description of the rate limiting policy behavior

B.

By refining the request definitions by adding a remaining Requests query parameter with description, type, and example

C.

By refining the response definitions by adding the out-of-the-box Anypoint Platform rate-limit-enforcement securityScheme with description, type, and example

D.

By refining the response definitions by adding the x-ratelimit-* response headers with description, type, and example

Question 3

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?

Options:

A.

A CloudHub worker fails with an out-of-memory exception

B.

API Manager has an extended outage during the initial deployment of the API implementation

C.

The AWS region goes offline with a major network failure to the relevant AWS data centers

D.

The Order Management System is Inaccessible due to a network outage in the organization's on-premises data center

Question 4

An API implementation is updated. When must the RAML definition of the API also be updated?

Options:

A.

When the API implementation changes the structure of the request or response messages

B.

When the API implementation changes from interacting with a legacy backend system deployed on-premises to a modern, cloud-based (SaaS) system

C.

When the API implementation is migrated from an older to a newer version of the Mule runtime

D.

When the API implementation is optimized to improve its average response time

Question 5

A code-centric API documentation environment should allow API consumers to investigate and execute API client source code that demonstrates invoking one or more APIs as part of representative scenarios.

What is the most effective way to provide this type of code-centric API documentation environment using Anypoint Platform?

Options:

A.

Enable mocking services for each of the relevant APIs and expose them via their Anypoint Exchange entry

B.

Ensure the APIs are well documented through their Anypoint Exchange entries and API Consoles and share these pages with all API consumers

C.

Create API Notebooks and include them in the relevant Anypoint Exchange entries

D.

Make relevant APIs discoverable via an Anypoint Exchange entry

Question 6

What CANNOT be effectively enforced using an API policy in Anypoint Platform?

Options:

A.

Guarding against Denial of Service attacks

B.

Maintaining tamper-proof credentials between APIs

C.

Logging HTTP requests and responses

D.

Backend system overloading

Question 7

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

Options:

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

Question 8

An organization wants to make sure only known partners can invoke the organization's APIs. To achieve this security goal, the organization wants to enforce a Client ID Enforcement policy in API Manager so that only registered partner applications can invoke the organization's APIs. In what type of API implementation does MuleSoft recommend adding an API proxy to enforce the Client ID Enforcement policy, rather than embedding the policy directly in the application's JVM?

Options:

A.

A Mule 3 application using APIkit

B.

A Mule 3 or Mule 4 application modified with custom Java code

C.

A Mule 4 application with an API specification

D.

A Non-Mule application

Question 9

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 10

What is the main change to the IT operating model that MuleSoft recommends to organizations to improve innovation and clock speed?

Options:

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

Question 11

What is the most performant out-of-the-box solution in Anypoint Platform to track transaction state in an asynchronously executing long-running process implemented as a Mule application deployed to multiple CloudHub workers?

Options:

A.

Redis distributed cache

B.

java.util.WeakHashMap

C.

Persistent Object Store

D.

File-based storage

Question 12

In which layer of API-led connectivity, does the business logic orchestration reside?

Options:

A.

System Layer

B.

Experience Layer

C.

Process Layer
