B. By default, the Anypoint CLI and Mule Maven plugin are not included in the Mule runtime
C. Access to Anypoint Platform API;s and Anypoint CLI can be controlled separately thruough the roles and permissions in Anypoint platform, so that specific users can get access to Anypoint CLI while others get access to the platform API's
D. API policies can be applied to the Anypoint platform API's so that only certain LOS's has access to specific functions

質問 3：
A rale limiting policy has been applied to a soap VI.2 API published in Clondhub. The API implementation catches errors in a global error handler on error propagate in the main flow for HTTP: RETRY_EXHAUSTED with HTTP status set to 429 and any with the HTTP status set to 500.
What is the expected H1TP status when the client exceeds the quota of the API calls?
A. HTTP status 401 unauthorized for policy violation
B. HTTP status 429 as defined in the HTTP:RETRY EXHAUSTED error handler in the API B. HTTP status 500 as defined in the ANY error handler in the API since an API:RETRY_EXHAUSTED will be generated
C. HTTP status 400 from the rate-limiting policy violation since the call does not reach the back-end
正解：B

質問 4：
How does timeout attribute help inform design decisions while using JMS connector listening for incoming messages in an extended architecture (XA) transaction?
A. The time allowed to pass between committing the transaction and the completion of the mule flow and then after the timeout flow processing triggers an error
B. The timeout specifies the time allowed to pass between receiving JMS messages on the same JMS connection and then after the timeout new JMS connection is established
C. The timeout defines the time that is allowed to pass without the transaction ending explicitly and after the timeout expires, the transaction rolls back
D. After the timeout is exceeded, stale JMS consumer threads are destroyed and new threads are created
正解：C

質問 5：
A mule application must periodically process a large dataset which varies from 6 GB lo 8 GB from a back-end database and write transform data lo an FTPS server using a properly configured bad job scope.
The performance requirements of an application are approved to run in the cloud hub 0.2 vCore with 8 GB storage capacity and currency requirements are met.
How can the high rate of records be effectively managed in this application?
A. Use streaming with a file store repeatable strategy reading records from the database and batch aggregator without any required configuration
B. Use streaming with a file storage repeatable strategy for reading records from the database and batch aggregator with streaming to write to FTPS
C. Use streaming with a file store repeatable strategy for reading records from the database and batch aggregator with an optimal size
D. Use streaming with an in-memory reputable store strategy for reading records from the database and batch aggregator with streaming to write to FTPS
正解：B

質問 6：
A mule application is required to periodically process large data set from a back-end database to Salesforce CRM using batch job scope configured properly process the higher rate of records.
The application is deployed to two cloudhub workers with no persistence queues enabled.
What is the consequence if the worker crashes during records processing?
A. Remaining records will be left and processed
B. Remaining records be processed by second worker
C. All the records will be processed from scratch by the second worker leading to duplicate processing
D. Remaining records will be processed by a new replacement worker
正解：A

質問 7：

A. To incorporate industry standard data formats
B. To have consistent data structure aligned in processes
C. To isolate areas within a bounded context
D. Because the model isolates the back and systems and support mule applications from change
E. There are multiple canonical definitions of each data type
正解：B,C

質問 8：
An insurance company has an existing API which is currently used by customers. API is deployed to customer hosted Mule runtime cluster. The load balancer that is used to access any APIs on the mule cluster is only configured to point to applications hosted on the server at port 443.
Mule application team of a company attempted to deploy a second API using port 443 but the application will not start and checking logs shows an error indicating the address is already in use.
Which steps must the organization take to resolve this error and allow customers to access both the API's?
A. Set HTTP listener configuration in both API's to allow for connections from multiple ports
B. Set the HTTP listener of the second API to use different port than the one used in the first API
C. Move the HTTP listener configurations from the API's and package them in a mule domain project using port 443
D. Change the base path of the HTTP listener configuration in the second API to a different one from the first API
正解：C

質問 9：
As a part of design , Mule application is required call the Google Maps API to perform a distance computation. The application is deployed to cloudhub.
At the minimum what should be configured in the TLS context of the HTTP request configuration to meet these requirements?

B. The configuration is built-in and nothing extra is required for the TLS context
C. Download the Google public certificate from a browser, generate a JKS file from it and add it in Truststore as part of the TLS context
D. Download the Google public certificate from a browser, generate JKS file from it and add it in key store as a part of TLS context
