質問 # 22
A developer is working on a project that requires encrypting all data before sending it to a backend application. To accomplish this, the developer will use PGP encryption in the Mule 4 Cryptography module.
What is required to encrypt the data before sending it to the backend application?
- A. The application needs to configure HTTPS TLS context information to encrypt the data
- B. The application needs to both the private and public keys to encrypt the data
- C. The application needs the public key from the backend service to encrypt the data
- D. The application needs the private key from the backend service to encrypt the data
正解：C
解説：
To encrypt the data before sending it to the backend application using PGP encryption, the application needs the public key from the backend service. PGP encryption uses a public-key cryptography system, which means that each party has a pair of keys: a public key and a private key. The public key is used to encrypt data, and the private key is used to decrypt data. Therefore, to encrypt data for a specific recipient (the backend service), the application needs to use the recipient's public key. The recipient can then use its own private key to decrypt the data.

質問 # 23
Refer to the exhibit.
A Mule application pom.xml configures the Maven Resources plugin to exclude parsing binary files in the project's src/main/resources/certs directory.
Which configuration of this plugin achieves a successful build?
- A.
- B.
- C.
- D.
正解：A
解説：
To configure the Maven Resources plugin to exclude parsing binary files in the project's src/main/resources/certs directory, option C should be used. This option specifies that any files with .cer or .jks extensions under the certs directory should be excluded from filtering. Filtering is a process of replacing placeholders with actual values in resource files during the build process. Binary files should not be filtered because they may become corrupted or unusable. Reference: https://maven.apache.org/plugins/maven-resources-plugin/examples/filter.html https://maven.apache.org/plugins/maven-resources-plugin/examples/include-exclude.html
質問 # 24
Refer to the exhibit.
The flow name is ''implementation'' with code for the MUnit test case.
When the MUnit test case is executed, what is the expected result?
- A. The test case fails with an assertion error
- B. The test throws an error and does not start
- C. The test case fails with an unexpected error type
- D. The test case passes
正解：A
解説：
Based on the code snippet and MUnit test case below, when the MUnit test case is executed, the expected result is that the test case fails with an assertion error. This is because the assert-equals processor compares two values for equality, and fails if they are not equal. In this case, the expected value is 'Hello World', but the actual value returned by the implementation flow is 'Hello Mule'. Therefore, the assertion fails and an error is thrown. Reference: https://docs.mulesoft.com/munit/2.3/assert-equals-processor
質問 # 25
A developer has created the first version of an API designed for business partners to work commodity prices.
What should developer do to allow more than one major version of the same API to be exposed by the implementation?
- A. In Anypoint Studio, generate scaffolding from the RAML, and then modify the flow names generated by APIKit to include a variable with the major version number
- B. In Design Center, open the RAML and modify baseUn to include a variable that indicates the version number
- C. In Anypoint Studio, generate scaffolding from the RAML, and the modify the <http:listerner> in the generated flows to include a parameter to replace the version number
- D. In Design Center, open the RAML and modify each operation to include the major version number
正解：B
解説：
To allow more than one major version of the same API to be exposed by the implementation, the developer should modify the baseUri property in the RAML file to include a variable that indicates the version number. The baseUri property defines the base URL of the API and can include variables that are replaced with actual values when mocking or deploying the API. By using a variable for the version number, the developer can expose different versions of the API using different base URLs and avoid conflicts or confusion. Reference: https://docs.mulesoft.com/api-designer/design-modify-raml-specs#baseuri https://docs.mulesoft.com/api-manager/2.x/api-versioning
質問 # 26
In a Mule project, Flow-1 contains a flow-ref to Flow-2 depends on data from Flow-1 to execute successfully.
Which action ensures the test suites and test cases written for Flow-1 and Flow-2 will execute successfully?
- A. Use ''Before Test Case'' To collect data from Flow-1 test cases before running Flow-2 test cases
- B. Use ''Set Event to pass the input that is needed, and keep the test cases for Flow-1 and Flow-2 independent
- C. Chain together the test suites and test cases for Flow-1 and Flow-2
- D. Use 'After Test Case' to produce the data needed from Flow-1 test cases to pass to Flow-2 test cases
正解：B
解説：
To ensure the test suites and test cases written for Flow-1 and Flow-2 will execute successfully, the developer should use a Set Event processor to pass the input that is needed by Flow-2, and keep the test cases for Flow-1 and Flow-2 independent. This way, the developer can isolate the testing of each flow and avoid coupling them together. Reference: https://docs.mulesoft.com/munit/2.3/munit-test-flow
質問 # 27
A system API that communicates to an underlying MySQL database is deploying to CloudHub. The DevOps team requires a readiness endpoint to monitor all system APIs.
Which strategy should be used to implement this endpoint?
- A. Create a dedicated endpoint that responds with the API status only
- B. Create a dedicated endpoint that responds with the API status and health of the server
- C. Use an existing resource endpoint of the API
- D. Create a dedicated endpoint that responds with the API status and reachability of the underlying systems
正解：D
解説：
To implement a readiness endpoint to monitor all system APIs, the developer should create a dedicated endpoint that responds with the API status and reachability of the underlying systems. This way, the DevOps team can check if the system API is ready to receive requests and if it can communicate with its backend systems without errors. Reference: https://docs.mulesoft.com/mule-runtime/4.3/deployment-strategies#readiness-probes
質問 # 28
Refer to the exhibits.
Bioinfo System API is implemented and published to Anypoint Exchange. A developer wants to invoke this API using its REST Connector.
What should be added to the POM?
- A.
- B.
- C.
- D.
- E.
正解：B
解説：
To invoke Bioinfo System API using its REST Connector, option E should be added to the pom.xml file. This option adds a dependency for Bioinfo System API REST Connector with its group ID, artifact ID, version, classifier, and type. The classifier specifies that it is a REST Connector (raml-client), and the type specifies that it is a Mule plugin (mule-plugin). Reference: https://docs.mulesoft.com/apikit/4.x/apikit-4-generate-from-rest-api-task#add-the-api-dependency-to-the-pom-file
質問 # 29
A healthcare portal needs to validate the token that it sends to a Mule API. The developer plans to implement a custom policy using the HTTP Policy Transform Extension to match the token received in the header from the heathcare portal.
Which files does the developer need to create in order to package the custom policy?
- A. XML template file, YAML configuration file
- B. JSON properties file, XML template file
- C. JSON properties file, YAML configuration file
- D. Deployable ZIP file, YAML configuration file
正解：A
解説：
To package a custom policy using the HTTP Policy Transform Extension, the developer needs to create an XML template file and a YAML configuration file. The XML template file defines the policy logic using Mule components and placeholders for user-defined properties. The YAML configuration file defines the metadata of the policy, such as its name, description, category, parameters, and dependencies. Reference: https://docs.mulesoft.com/api-manager/2.x/http-policy-transform#packaging-the-policy
質問 # 30
A heathcare customer wants to use hospital system data, which includes code that was developed using legacy tools and methods. The customer has created reusable Java libraries in order to read the data from the system.
What is the most effective way to develop an API retrieve the data from the hospital system?
- A. Create the Java code in your project and invoice the data from the code
- B. Include the libraries writes deploying the code into the runtime
- C. Install libraries in a local repository and refer to it in the pm.xml file
- D. Refer to JAR files in the code
正解：C
解説：
To develop an API that retrieves data from a hospital system using reusable Java libraries, the developer should install libraries in a local repository and refer to it in the pom.xml file. This way, the developer can use Maven to manage dependencies and invoke Java code from Mule applications using Java Module operations. Reference: https://docs.mulesoft.com/mule-runtime/4.3/java-module-reference#add-the-java-module-to-your-project https://docs.mulesoft.com/mule-runtime/4.3/java-module-reference#invoke-java-code
質問 # 31
A mule application exposes and API for creating payments. An Operations team wants to ensure that the Payment API is up and running at all times in production.
Which approach should be used to test that the payment API is working in production?
- A. Create a health check endpoint that listens on a separate port and uses a separate HTTP Listener configuration from the API
- B. Create a health check endpoint that reuses the same port number and HTTP Listener configuration as the API itself
- C. Monitor the Payment API directly sending real customer payment data
- D. Configure the application to send health data to an external system
正解：A
解説：
To test that the payment API is working in production, the developer should create a health check endpoint that listens on a separate port and uses a separate HTTP Listener configuration from the API. This way, the developer can isolate the health check endpoint from the API traffic and avoid affecting the performance or availability of the API. The health check endpoint should return a simple response that indicates the status of the API, such as OK or ERROR. Reference: https://docs.mulesoft.com/api-functional-monitoring/afm-create-monitor#create-a-monitor
質問 # 32
A scatter-gather router is configured with four routes:Route A, B, C and D.
Route C false.
- A. Payload ['2']
- B. Error,errorMessage,payload.failures['2']
- C. Payload failures['2']
- D. Error,errorMesage.payload.results ['2']
正解：D
解説：
The result of accessing route C failure is Error,errorMessage,payload.failures['2']. This is because a scatter-gather router returns an aggregated message that contains an array of results from each route and an array of failures from each route. The failures array contains error objects with information about each failed route execution. To access route C failure, which is the third route (index 2), the developer needs to use Error.errorMessage.payload.failures['2'] expression. Reference: https://docs.mulesoft.com/mule-runtime/4.3/scatter-gather-reference#scatter-gather-output
質問 # 33
Refer to the exhibit.
A Mute Object Store is configured with an entry TTL of one second and an expiration interval of 30 seconds.
What is the result of the flow if processing between os'store and os:retrieve takes 10 seconds?
- A. nullPayload
- B. testPayload
- C. OS:KEY_NOT_FOUND
- D. originalPayload
正解：A
解説：
The result of the flow is nullPayload if processing between os:store and os:retrieve takes 10 seconds. This is because the entry TTL of the object store is one second, which means that any stored value expires after one second and is removed from the object store. The expiration interval of 30 seconds only determines how often the object store checks for expired values, but it does not affect the TTL. Therefore, when os:retrieve tries to get the value after 10 seconds, it returns nullPayload because the value has already expired and been removed. Reference: https://docs.mulesoft.com/object-store/osv2-faq#how-does-the-time-to-live-work
質問 # 34
Multiple individual Mute application need to use the Mule Maven plugin to deploy to CloudHub.
The plugin configuration should .. reused where necessary and anything project, specific should be property-based.
Where should the Mule Maven details be configured?
- A. Settings, xml
- B. A Bill of Materials (BOM) parent pm
- C. A parent pom.xml
- D. Pom, xml
正解：C
解説：
To reuse Mule Maven plugin configuration across multiple individual Mule applications, the developer should use a parent pom.xml file. A parent pom.xml file defines common configuration for one or more child projects that inherit from it. The developer can specify common properties and dependencies for all child projects in the parent pom.xml file, such as Mule Maven plugin configuration, and then reference them in each child project's pom.xml file using placeholders. Reference: https://docs.mulesoft.com/mule-runtime/4.3/mmp-concept#parent-pom https://maven.apache.org/guides/introduction/introduction-to-the-pom.html#Project_Inheritance
質問 # 35
Refer to the exhibit.
What action must be performed to log all the errors raised by the VM Connector?
- A. Add <AsyncLOgger name='orgroute.extensions vm' level=ERROR'I> inside the Logger tag
- B. Configure <Logger level-'ERROR'/> inside the VM Connector configuration
- C. Nothing, as error-level events are automatically logged
- D. Add <AsyncLOgger name='orgroute.extensions vm' level=ERROR'/> inside the Appenders tag
正解：D
解説：
To log all the errors raised by the VM Connector, the developer needs to add an async logger with the name 'org.mule.extension.vm' and the level 'ERROR' inside the appenders tag of the log4j2.xml file. This will enable logging all error-level events generated by the VM Connector to the console appender. Reference: https://docs.mulesoft.com/mule-runtime/4.3/logging-in-mule#configuring-custom-logging-settings
質問 # 36
The Center for Enablement team published a common application as a reusable module to the central Nexus repository.
How can the common application be included in all API implementations?
- A. Add a Maven dependency in the PCM file with multiple-plugin as <classifier>
- B. Add a Maven dependency in the POM file with jar as <classifier>
- C. Copy the common application's source XML file and out it in a new flow file in the src/main/mule folder
- D. Download the common application from Naxus and copy it to the src/main/resources folder in the API
正解：B
解説：
To include a common application as a reusable module in all API implementations, the developer should add a Maven dependency in the POM file with jar as <classifier>. This way, the developer can reuse Mule code from another application by packaging it as a JAR file and adding it as a dependency in the POM file of the API implementation. The classifier element specifies that it is a JAR file. Reference: https://docs.mulesoft.com/mule-runtime/4.3/mmp-concept#add-a-maven-dependency-to-the-pom-file
質問 # 37
A Mule application uses API autodiscovery to access and enforce policies for a RESTful implementation.
- A. Northing because flowRef is an optional attribute which can be passed runtime
- B. The name of the flow that has HTTP listener to receive all incoming RESTful operation requests
- C. The name of the flow that has APlkit Console to receive all incoming RESTful operation requests.
- D. Any of the APIkit generate implement flows
正解：B
解説：
To use API autodiscovery to access and enforce policies for a RESTful implementation, flowRef must be set to the name of the flow that has HTTP listener to receive all incoming RESTful operation requests. This way, API autodiscovery can identify the API implementation and associate it with the corresponding API specification and policies in API Manager. The flow that has HTTP listener is usually the main flow that contains the APIKit Router. Reference: https://docs.mulesoft.com/api-manager/2.x/api-auto-discovery-new-concept#flowref
質問 # 38
A Mule implementation uses a HTTP Request within an Unit Successful scope to connect to an API.
How should a permanent error response like HTTP:UNAUTHORIZED be handle inside Until Successful to reduce latency?
- A. Put the HTTP Request inside a try scope in Unit Successful.
In the error handler, use On Error Continue to catch permanent errors like HTTP UNAUTHORIZED. - B. In Until Successful configuration, set the retry count to 1 for error type HTTP: UNAUTHORIZED.
- C. Put the HTTP Request inside a try scope in Unit Successful.
In the error handler, use On Error Propagate to catch permanent errors like HTTP UNAUTHORIZED. - D. Configure retrying until a MULERETRY_EXHAUSTED error is raised or the API responds back with a successful response.
正解：A
解説：
To handle a permanent error response like HTTP:UNAUTHORIZED inside Until Successful, the developer should put the HTTP Request inside a try scope in Unit Successful, and use On Error Continue to catch permanent errors like HTTP UNAUTHORIZED in the error handler. This way, the developer can avoid retrying requests that will always fail due to a permanent error, and reduce latency. On Error Continue allows the flow to continue processing after handling the error. Reference: https://docs.mulesoft.com/mule-runtime/4.3/until-successful-scope https://docs.mulesoft.com/mule-runtime/4.3/on-error-continue-concept
質問 # 39
A Mule application need to invoice an API hosted by an external system to initiate a process. The external API takes anywhere between one minute and 24 hours to compute its process.
Which implementation should be used to get response data from the external API after it completes processing?
- A. Expose an HTTP callback API in Mule and register it with the external system
- B. Use an HTTP Connector to invoke the API and wait for a response
- C. Use a Scheduler to check for a response every minute
- D. Use an HTTP Connector inside Async scope to invoice the API and wait for a response
正解：A
解説：
To get response data from the external API after it completes processing, the developer should expose an HTTP callback API in Mule and register it with the external system. This way, the external API can invoke the callback API with the response data when it is ready, instead of making the Mule application wait for a long time or poll for a response repeatedly. Reference: https://docs.mulesoft.com/mule-runtime/4.3/http-listener-ref#callback
質問 # 40
Which statement is true about using mutual TLS to secure an application?
- A. Mutual TLS authenticates the identity of the server before the identity of the client
- B. Mutual TLS increases the encryption strength versus server-side TLS alone
- C. Mutual TLS ensures only authorized end users are allowed to access an endpoint
- D. Mutual TLS requires a hardware security module to be used
正解：A
解説：
Mutual TLS (mTLS) is an extension of TLS that requires both parties (client and server) to present their certificates to each other during the handshake process. This way, both parties can verify each other's identity and establish a secure connection. The authentication of the server happens before the authentication of the client, as the server sends its certificate first and then requests the client's certificate. Reference: https://docs.mulesoft.com/mule-runtime/4.3/tls-configuration#mutual-authentication
質問 # 41
A custom policy needs to be developed to intercept all cutbound HTTP requests made by Mule applications.
Which XML element must be used to intercept outbound HTTP requests?
- A. htt-policy:operation
- B. http-policy:source
- C. It is not possible to intercept outgoing HTTP requests, only inbound requests
- D. http-policy:processor
正解：B
解説：
The http-policy:processor element is used to intercept outbound HTTP requests made by Mule applications. It allows customizing the request before it is sent to the target API and modifying the response after it is received from the target API. Reference: https://docs.mulesoft.com/api-manager/2.x/policy-mule4-custom-policy#policy-xml-file
質問 # 42
Refer to the exhibit.
Based on the code snippet, schema,json file, and payload below, what is the outcome of the given code snippet when a request is sent with the payload?
- A. The Mule flow will execute successfully with status code 200m and a response will display the message '' Age in years which must equal to or greater than zero.''
- B. The Mule flow will throw the exception 'JSON:SCHEMA_NOT_HONOURED
- C. The Mule flow will execute successfully with status code 200, and the response will be the JSON sent in request
- D. The Mule flow will execute successfully with status code 204
正解：B
解説：
Based on the code snippet, schema.json file, and payload below, the outcome of the given code snippet when a request is sent with the payload is that the Mule flow will throw the exception 'JSON:SCHEMA_NOT_HONOURED'. This is because the payload does not conform to the schema.json file, which specifies that age must be a number greater than or equal to zero. The payload has age as a string with a negative value, which violates the schema. Therefore, the validate-schema operation throws an error with type 'JSON:SCHEMA_NOT_HONOURED'. Reference: https://docs.mulesoft.com/json-module/1.1/json-validate-schema
質問 # 43
Which properties are mandatory on the HTTP Connector configuration in order to use the OAuth 2.0 Authorization Code grant type for authentication?
- A. Token URL, authorization URL, client ID, client secret local callback URL
- B. External callback URL, access token URL, client ID response access token
- C. External callback URL, access token URL, client ID, response refresh token
- D. External callback URL, access token URL, local authorization URL, authorization URL, client ID, client secret
正解：D
解説：
To use the OAuth 2.0 Authorization Code grant type for authentication, the HTTP Connector configuration requires the following properties: token URL, authorization URL, client ID, client secret, and local callback URL. The token URL is the endpoint of the authorization server that provides access tokens. The authorization URL is the endpoint of the authorization server that initiates the user consent flow. The client ID and client secret are the credentials of the Mule application registered with the authorization server. The local callback URL is the endpoint of the Mule application that receives the authorization code from the authorization server. Reference: https://docs.mulesoft.com/http-connector/1.6/http-authentication#oauth-2-0
質問 # 44
Refer to the exhibit.
A developer generates the base scaffolding for an API in Anypoint Studio.
Which HTTP status code is returned while testing using the API Kit console if no values are entered in client-secret?
- A. HTTP status code:500
- B. HTTP status code:400
- C. HTTP status code:403
- D. HTTP status code:200
正解：C
解説：
Based on the code snippet and schema.json file below, when testing using the API Kit console if no values are entered in client-secret, HTTP status code 403 (FORBIDDEN) is returned. This is because client-secret is defined as a required header parameter in schema.json file, which means that it must be present in every request. If no values are entered in client-secret, then it is equivalent to omitting this header parameter, which violates the schema and causes APIKit Router to return HTTP status code 403. Reference: https://docs.mulesoft.com/apikit/4.x/apikit-4-headers
質問 # 45
Mule application A is deployed to CloudHub and is using Object Store v2. Mute application B is also deployed to CloudHub.
Which approach can Mule application B use to remove values from Mule application A'S Object Store?
- A. Object Store v2 REST API
- B. CloudHub REST API
- C. CloudHub Connector
- D. Object Store Connector
正解：A
解説：
To remove values from Mule application A's Object Store v2, Mule application B can use Object Store v2 REST API. This API allows performing operations on Object Store v2 resources using HTTP methods, such as GET, POST, PUT, and DELETE. Mule application B can use the DELETE method to remove values from Mule application A's Object Store v2 by specifying the object store ID and the key of the value to delete. Reference: https://docs.mulesoft.com/object-store/osv2-apis
質問 # 46
Which statement is true when using XML SDK for creating custom message processors?
- A. An XML SDK provides both inbound and outbound operations
- B. Properties are fields defined by an end user of the XML SDK component and serve as a global configuration for the entire Mule project in which they are used
- C. Operations can be reused in recursive calls
- D. All operations are public
正解：B
解説：
When using XML SDK for creating custom message processors, all operations are public by default and can be used by any Mule application that imports them. There is no way to make an operation private or protected in XML SDK. Reference: https://docs.mulesoft.com/mule-sdk/1.1/xml-sdk#operations
