Mulesoft MCPA-Level-1 Exam Questions

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

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When the API implementation is migrated from an older to a newer version of the Mule runtime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

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

B.

1. Central IT owns and focuses on Experience Layer APIs
2. LOB IT owns and focuses on Process Layer APIs
3. App Developers owns and focuses on System Layer APIs

C.

1. App Developers owns and focuses on Experience Layer APIs
2. LOB IT owns and focuses on Process Layer APIs

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

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

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 ratelimit-
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

An organization makes a strategic decision to move towards an IT operating model that emphasizes consumption of reusable IT assets using modern APIs (as defined by MuleSoft). What best describes each modern API in relation to this new IT operating model?

A.

Each modern API has its own software development lifecycle, which reduces the need for documentation and automation

B.

Each modem API must be treated like a product and designed for a particular target audience (for instance, mobile app developers)

C.

Each modern API must be easy to consume, so should avoid complex authentication mechanisms such as SAML or JWT D

D.

Each modern API must be REST and HTTP based

A retail company is using an Order API to accept new orders. The Order API uses a JMS
queue to submit orders to a backend order management service. The normal load for
orders is being handled using two (2) CloudHub workers, each configured with 0.2 vCore.
The CPU load of each CloudHub worker normally runs well below 70%. However, several
times during the year the Order API gets four times (4x) the average number of orders.
This causes the CloudHub worker CPU load to exceed 90% and the order submission time
to exceed 30 seconds. The cause, however, is NOT the backend order management
service, which still responds fast enough to meet the response SLA for the Order API.
What is the MOST resource-efficient way to configure the Mule application's CloudHub
deployment to help the company cope with this performance challenge?

A.

Permanently increase the size of each of the two (2) CloudHub workers by at least four
times (4x) to one (1) vCore

B.

Use a vertical CloudHub autoscaling policy that triggers on CPU utilization greater than
70%

C.

Permanently increase the number of CloudHub workers by four times (4x) to eight (8)
CloudHub workers

D.

Use a horizontal CloudHub autoscaling policy that triggers on CPU utilization greater
than 70%

An API with multiple API implementations (Mule applications) is deployed to both CloudHub and customer-hosted Mule runtimes. All the deployments are managed by the MuleSoft-hosted control plane. An alert needs to be triggered whenever an API implementation stops responding to API requests, even if no API clients have called the API implementation for some time. What is the most effective out-of-the-box solution to create these alerts to monitor the API implementations?

A. Create monitors in Anypoint Functional Monitoring for the API implementations, where each monitor repeatedly invokes an API implementation endpoint

B. Add code to each API client to send an Anypoint Platform REST API request to generate a custom alert in Anypoint Platform when an API invocation times out

C. Handle API invocation exceptions within the calling API client and raise an alert from that API client when such an exception is thrown

D. Configure one Worker Not Responding alert.in Anypoint Runtime Manager for all API implementations that will then monitor every API implementation
