MuleSoft MCIA-Level-1 問題集

質問 1：
A company is modernizing its legal systems lo accelerate access lo applications and data while supporting the adoption of new technologies. The key to achieving this business goal is unlocking the companies' key systems and dala including microservices miming under Docker and kubernetes containers using apis.
Considering the current aggressive backlog and project delivery requirements the company wants to take a strategic approach in the first phase of its transformation projects by quickly deploying API's in mule runtime that are able lo scale, connect to on premises systems and migrate as needed.
Which runtime deployment option supports company's goals?
A. Runtime fabric on Vmware metal
B. Customer hosted self provisioned runtimes
C. Cloudhub runtimes
D. Runtime fabric on self managed Kubernetes

質問 2：
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

質問 3：
The AnyAirline organization's passenger reservations center is designing an integration solution that combines invocations of three different System APIs (bookFlight, bookHotel, and bookCar) in a business transaction.
Each System API makes calls to a single database.
The entire business transaction must be rolled back when at least one of the APIs fails.
What is the most idiomatic (used for its intended purpose) way to integrate these APIs in near real-time that provides the best balance of consistency, performance, and reliability?
A. Implement local transactions in each API implementation
Coordinate between the API implementations using a Saga pattern
Apply various compensating actions depending on where a failure occurs
B. Implement eXtended Architecture (XA) transactions between the API implementations Coordinate between the API implementations using a Saga pattern Implement caching in each API implementation to improve performance
C. Implement local transactions within each API implementation
Configure each API implementation to also participate in the same eXtended Architecture (XA) transaction Implement caching in each API implementation to improve performance
D. Implement an eXtended Architecture (XA) transaction manager in a Mule application using a Saga pattern Connect each API implementation with the Mule application using XA transactions Apply various compensating actions depending on where a failure occurs
正解：A

質問 4：
An organization uses a four(4) node customer hosted Mule runtime cluster to host one(1) stateless api implementation. The API is accessed over HTTPS through a load balancer that uses round-robin for load distribution. Each node in the cluster has been sized to be able to accept four(4) times the current number of requests.
Two(2) nodes in the cluster experience a power outage and are no longer available. The load balancer directs the outage and blocks the two unavailable the nodes from receiving further HTTP requests.
What performance-related consequence is guaranteed to happen to average, assuming the remaining cluster nodes are fully operational?
A. 100% increase in the number of requests received by each remaining node
B. 100% increase in the average response time of the API
C. 50% reduction in the throughput of the API
D. 50% increase in the JVM heap memory consumed by each remaining node
正解：B

質問 5：
A trading company handles millions of requests a day. Due to nature of its business, it requires excellent performance and reliability within its application.
For this purpose, company uses a number of event-based API's hosted on various mule clusters that communicate across a shared message queue sitting within its network.
Which method should be used to meet the company's requirement for its system?
A. JMS manual acknowledgements with a reliability pattern
B. XA transactions and XA connected components
C. JMS transactions
D. VM queues with reliability pattern
正解：C

質問 6：
49 of A popular retailer is designing a public API for its numerous business partners. Each business partner will invoke the API at the URL 58. https://api.acme.com/partnefs/vl. The API implementation is estimated to require deployment to 5 CloudHub workers.
The retailer has obtained a public X.509 certificate for the name apl.acme.com, signed by a reputable CA, to be used as the server certificate.
Where and how should the X.509 certificate and Mule applications be used to configure load balancing among the 5 CloudHub workers, and what DNS entries should be configured in order for the retailer to support its numerous business partners?
A. Add the X.509 certificate to the Mule application's deployable archive, then configure a CloudHub Dedicated Load Balancer (DLB) for each of the Mule application's CloudHub workers Create a CNAME for api.acme.com pointing to the DLB's A record
B. Add the X.509 certificate to a CloudHub Dedicated Load Balancer (DLB), not to the Mule application Create a CNAME for api.acme.com pointing to the DLB's A record
C. Add the x.509 certificate to the Mule application's deployable archive, then configure the CloudHub Shared Load Balancer (SLB) for each of the Mule application's CloudHub workers Create a CNAME for api.acme.com pointing to the SLB's A record
D. Add the X.509 certificate to the CloudHub Shared Load Balancer (SLB), not to the Mule application Create a CNAME for api.acme.com pointing to the SLB's A record
正解：B

質問 7：
A Mule application uses APIkit for SOAP to implement a SOAP web service. The Mule application has been deployed to a CloudHub worker in a testing environment.
The integration testing team wants to use a SOAP client to perform Integration testing. To carry out the integration tests, the integration team must obtain the interface definition for the SOAP web service.
What is the most idiomatic (used for its intended purpose) way for the integration testing team to obtain the interface definition for the deployed SOAP web service in order to perform integration testing with the SOAP client?
A. Retrieve the RAML file(s) from the deployed Mule application
B. Retrieve the XML file(s) from Runtime Manager
C. Retrieve the OpenAPI Specification file(s) from API Manager
D. Retrieve the WSDL file(s) from the deployed Mule application
正解：B

質問 8：
An organization uses one specific CloudHub (AWS) region for all CloudHub deployments. How are CloudHub workers assigned to availability zones (AZs) when the organization's Mule applications are deployed to CloudHub in that region?
A. Workers are randomly distributed across available AZs within that region.
B. AZs are selected as part of the Mule application's deployment configuration.
C. An AZ is randomly selected for a Mule application, and all the Mule application's CloudHub workers are assigned to that one AZ
D. Workers belonging to a given environment are assigned to the same AZ within that region.
