MuleSoft MCPA-Level-1 問題集

質問 1：
A Platform Architect inherits a legacy monolithic SOAP-based web service that performs a number of tasks, including showing all policies belonging to a client. The service connects to two back-end systems - a life- insurance administration system and a general-insurance administration system - and then queries for insurance policy information within each system, aggregates the results, and presents a SOAP-based response to a user interface (UI).
The architect wants to break up the monolithic web service to follow API-led conventions.
Which part of the service should be put into the process layer?
A. Querying the data from the administration systems
B. Authenticating and maintaining connections to each of the back-end administration systems
C. Presenting the SOAP-based response to the UI
D. Combining the insurance policy information from the administration systems

質問 3：
A business process is being implemented within an organization's application network. The architecture group proposes using a more coarse-grained application network design with relatively fewer APIs deployed to the application network compared to a more fine- grained design.
Overall, which factor typically increases with a more coarse-grained design for this business process implementation and deployment compared with using a more fine-grained design?
A. The number of possible connections between API implementations in the application network
B. The usage of network infrastructure resources by the application network
C. The complexity of each API implementation
D. The number of discoverable assets related to APIs deployed in the application network

質問 4：
An organization has several APIs that accept JSON data over HTTP POST. The APIs are all publicly available and are associated with several mobile applications and web applications.
The organization does NOT want to use any authentication or compliance policies for these APIs, but at the same time, is worried that some bad actor could send payloads that could somehow compromise the applications or servers running the API implementations.
What out-of-the-box Anypoint Platform policy can address exposure to this threat?
A. Apply a Header injection and removal policy that detects the malicious data before it is used
B. Shut out bad actors by using HTTPS mutual authentication for all API invocations
C. Apply a JSON threat protection policy to all APIs to detect potential threat vectors
D. Apply an IP blacklist policy to all APIs; the blacklist will Include all bad actors

質問 5：
What is true about where an API policy is defined in Anypoint Platform and how it is then applied to API instances?
A. The API policy is defined in API Manager, and then applied to ALL API instances in the specified environment
B. The API policy Is defined In API Manager for a specific API Instance, and then ONLY applied to the specific API instance
C. The API policy Is defined in API Manager and then automatically applied to ALL API instances
D. The API policy Is defined In Runtime Manager as part of the API deployment to a Mule runtime, and then ONLY applied to the specific API Instance

質問 6：
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 number of replicas of the API implementation
B. Modify the API client to split the problematic request into smaller, less-demanding requests
C. Throttle the APT client to reduce the number of requests per minute
D. Increase the vCPU resources of the API implementation

質問 7：
How can the application of a rate limiting API policy be accurately reflected in the RAML definition of an API?
A. By refining the request definitions by adding a remaining Requests query parameter with description, type, and example
B. By refining the resource definitions by adding a description of the rate limiting policy behavior
C. By refining the response definitions by adding the x-ratelimit-* response headers with description, type, and example
D. By refining the response definitions by adding the out-of-the-box Anypoint Platform rate-limit- enforcement securityScheme with description, type, and example

質問 8：
What is typically NOT a function of the APIs created within the framework called API-led connectivity?
A. They allow for innovation at the user Interface level by consuming the underlying assets without being aware of how data Is being extracted from backend systems.
B. They provide an additional layer of resilience on top of the underlying backend system, thereby insulating clients from extended failure of these systems.
C. They can compose data from various sources and combine them with orchestration logic to create higher level value.
D. They reduce the dependency on the underlying backend systems by helping unlock data from backend systems In a reusable and consumable way.

質問 9：
To minimize operation costs, a customer wants to use a CloudHub 1.0 solution. The customer's requirements are:
* Separate resources with two Business groups
* High-availability (HA) for all APIs
* Route traffic via Dedicated load balancer (DLBs)
* Separate environments into production and non-production
Which solution meets the customer's needs?
A. One production and one non-production Virtual Private Cloud (VPC).
Use availability zones to differentiate between Business groups.
Allocate maximum CIDR per VPCs to ensure HA across availability zones
B. One production and one non-production Virtual Private Cloud (VPC) per Business group.
Minimize CIDR aligning with projected application total.
Divide availability zones during deployment of APIs for HA.
C. One production and one non-production Virtual Private Claud (VPC).
Configure subnet to differentiate between business groups.
Allocate maximum CIDR per VPCs to make it easier to add Child groups.
Span VPC to cover three availability zones.
D. One production and one non-production Virtual Private Cloud (VPC) per Business group.
Minimize CIDR aligning with projected application total.
Choose a MuleSoft CloudHub 1.0 region with multiple availability zones.
Deploy multiple workers for HA,
