Mulesoft MCPA-Level-1 Exam Questions

Several times a week, an API implementation shows several thousand requests per minute in an Anypoint Monitoring dashboard, Between these bursts, the dashboard shows between two and five requests per minute. The API implementation is running on Anypoint Runtime Fabric with two non-clustered replicas, reserved vCPU 1.0 and vCPU Limit 2.0.
An API consumer has complained about slow response time, and the dashboard shows the 99 percentile is greater than 120 seconds at the time of the complaint. It also shows greater than 90% CPU usage during these time periods.
In manual tests in the QA environment, the API consumer has consistently reproduced the slow response time and high CPU usage, and there were no other API requests at this time. In a brainstorming session, the engineering team has created several proposals to reduce the response time for requests.
Which proposal should be pursued first?

A. Increase the vCPU resources of the API implementation

B. Modify the API client to split the problematic request into smaller, less-demanding requests

C. Increase the number of replicas of the API implementation

D. Throttle the APT client to reduce the number of requests per minute

A company stores financial transaction data in two legacy systems. For each legacy system, a separate, dedicated System API (SAPI) exposes data for that legacy system. A Process API (PAPI) merges the data retrieved from ail of the System APIs into a common format. Several API clients call the PAPI through its public domain name.
The company now wants to expose a subset of financial data to a newly developed mobile application that uses a different Bounded Context Data Model. The company wants to follow MuleSoft's best practices for building out an effective application network.
Following MuleSoft's best practices, how can the company expose financial data needed by the mobile application in a way that minimizes the impact on the currently running API clients, API implementations, and support asset reuse?

A. Add two new Experience APIs (EAPI-i and EAPI-2}.
Add Mobile PAPI-2 to expose the Intended subset of financial data as requested.
Both PAPIs access the Legacy Systems via SAPI-1 and SAP]-2.

B. Add two new Experience APIs (EAPI-i and EAPI-2}.
Add Mobile PAPI-2 to expose the Intended subset of financial data as requested.
Both PAPIs access the Legacy Systems via SAPI-1 and SAP]-2.

C. Create a new mobile Experince API (EAPI) chat exposes that subset of PAPI endpoints.
Add transformtion login to the mobile Experince API implementation to make mobile data compatible with the required PAPIs.

D. Develop and deploy is new PAPI implementation with data transformation and ... login to support this required endpoints of both mobile and web clients.
Deploy an API Proxy with an endpoint from API Manager that redirect the existing PAPI endpoints to the new PAPI.

A company deployed an API to a single worker/replica in the shared cloud in the U.S. West Region. What happens when the Availability Zone experiences an outage?

A. CloudHub will auto-redeploy the APL in the U.S. East Region

B. The APT will be unavailable until the availability comes back online, at which time the worker/replica will be auto-restarted

C. CloudHub will auto-redeploy the API in another Availability Zone in the U.S. West Region

D. The Anypoint Platform admin is alerted when the AP] is experiencing an outage and needs the trigger the CI/CD pipeline to redeploy to the US. East Region

Refer to the exhibit.

A developer is building a client application to invoke an API deployed to the STAGING
environment that is governed by a client ID enforcement policy.
What is required to successfully invoke the API?

A.

The client ID and secret for the Anypoint Platform account owning the API in the STAGING environment

B.

The client ID and secret for the Anypoint Platform account's STAGING environment

C.

The client ID and secret obtained from Anypoint Exchange for the API instance in the
STAGING environment

D.

A valid OAuth token obtained from Anypoint Platform and its associated client ID and
secret

An enterprise is embarking on the API-led digital transformation journey, and the central IT team has started to define System APIs. Currently there is no Enterprise Data Model being defined within the enterprise, and the definition of a clean Bounded Context Data Model requires too much effort. According to MuleSoft's recommended guidelines, how should the System API data model be defined?

A. If there are misspellings of the data fields in the back-end system, Systerm APIs should not correct it, and expose it as-is to mirror the back-end systems

B. The data model of the System APIs should make use of data types that approximately mirror those from the back-end systems

C. The data model should define its own naming convention, and not follow the same naming as the back-end systems

D. The System APIs should expose all back-end system fields

What do the API invocation metrics provided by Anypoint Platform provide?

A.

ROI metrics from APIs that can be directly shared with business users

B.

Measurements of the effectiveness of the application network based on the level of reuse

C.

Data on past API invocations to help identify anomalies and usage patterns across various APIs

D.

Proactive identification of likely future policy violations that exceed a given threat
threshold

4A developer for a transportation organization is implementing exactly one processing functionality in a Reservation Mule application to process and store passenger records. This Reservation application will be deployed to multiple CloudHub workers/replicas. It is possible that several external systems could send duplicate passenger records to the Reservation application.
An appropriate storage mechanism must be selected to help the Reservation application process each passenger record exactly once as much as possible. The selected storage mechanism must be shared by all the CloudHub workers/replicas in order to synchronize the state information to assist attempting exactly once processing of each passenger record by the deployed Reservation Mule application.
Which type of simple storage mechanism in Anypoint Platform allows the Reservation Mule application to update and share data between the CloudHub workers/replicas exactly once, with minimal development effort?

A. Persistent Object Store

B. Runtime Fabric Object Store

C. Non-persistent Object Store

D. In-memory Mule Object Store

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 API's 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 update should be identified as a project risk and full regression testing of the functionality that uses this API should be run

B.

The API producer should be contacted to understand the change to existing functionality

C.

The API producer should be requested to run the old version in parallel with the new one

D.

The API client code ONLY needs to be changed if it needs to take advantage of new
features
