MuleSoft MCIA-Level-1 問題集

質問 1：
A Mule application is being designed To receive nightly a CSV file containing millions of records from an external vendor over SFTP, The records from the file need to be validated, transformed. And then written to a database. Records can be inserted into the database in any order.
In this use case, what combination of Mule components provides the most effective and performant way to write these records to the database?
A. Use a Parallel for Each scope to Insert records one by one into the database
B. Use a Batch job scope to bulk insert records into the database.
C. Use a Scatter-Gather to bulk insert records into the database
D. Use a DataWeave map operation and an Async scope to insert records one by one into the database.

質問 6：
Refer to the exhibit.

One of the backend systems invoked by an API implementation enforces rate limits on the number of requests a particular client can make. Both the backend system and the API implementation are deployed to several non-production environments in addition to production.
Rate limiting of the backend system applies to all non-production environments. The production environment, however, does NOT have any rate limiting.
What is the most effective approach to conduct performance tests of the API implementation in a staging (non-production) environment?
A. Include logic within the API implementation that bypasses invocations of the backend system in a performance test situation. Instead invoking local stubs that replicate typical backend system responses then conduct performance tests using this API Implementation
B. Conduct scaled-down performance tests in the staging environment against the rate limited backend system then upscale performance results to full production scale
C. Create a mocking service that replicates the backend system's production performance characteristics.
Then configure the API implementation to use the mocking service and conduct the performance tests
D. Use MUnit to simulate standard responses from the backend system then conduct performance tests to identify other bottlenecks in the system

質問 8：
A mule application is being designed to perform product orchestration. The Mule application needs to join together the responses from an inventory API and a Product Sales History API with the least latency.
To minimize the overall latency. What is the most idiomatic (used for its intended purpose) design to call each API request in the Mule application?
A. Call each API request in a separate route of a Scatter-Gather
B. Call each API request in a separate route of a Parallel For Each scope
C. Call each API request in a separate lookup call from Dataweave reduce operator
D. Call each API request in a separate Async scope
正解：A

質問 9：
An organization has deployed both Mule and non-Mule API implementations to integrate its customer and order management systems. All the APIs are available to REST clients on the public internet.
The organization wants to monitor these APIs by running health checks: for example, to determine if an API can properly accept and process requests. The organization does not have subscriptions to any external monitoring tools and also does not want to extend its IT footprint.
What Anypoint Platform feature provides the most idiomatic (used for its intended purpose) way to monitor the availability of both the Mule and the non-Mule API implementations?
A. API Functional Monitoring
B. API Manager
C. Runtime Manager
D. Anypoint Visualizer
正解：D
