SALESFORCE-MULESOFT-DEVELOPER-II Online Practice Questions and Answers

Correct Answer: A

The validate-customer flow uses an until-successful scope to validate each field of the customer data. The until-successful scope executes its processors until they succeed or exhausts the maximum number of retries. If any processor fails, it

raises an error and stops executing the remaining processors. Therefore, if only the email address is invalid, a VALIDATION.INVALID_EMAIL error is raised and the validation of appointment date and customer name is skipped.

Correct Answer: B

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. https:// docs.mulesoft.com/mule-runtime.3/tls-configuration#mutualauthentication

Correct Answer: B

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. https://docs.mulesoft.com/mule-runtime.3/logging-in-mule#configuringcustom-logging-settings

Correct Answer: C

When working with correlation IDs, the HTTP Listener generates correlation IDs unless a correlation ID is received in the HTTP request. In that case, it propagates the received correlation ID throughout the flow execution. Correlation IDs are used to track events across different flows or applications. https://docs.mulesoft.com/mule-runtime.3/about-mule-message#message-attributes

Correct Answer: B

To convert a JKS keystore to PKCS12, the developer needs to use the keytool-importkeystore command with the following options: -srckeystore keystore.jks -srcstoretype JKS -destkeystore keystore.p12 -deststoretype PKCS12. This

command imports all entries from a source JKS keystore (keystore.jks) into a destination PKCS12 keystore (keystore.p12).

Correct Answer: C

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'.

Correct Answer: D

To manually approve or reject request access when registering a client application with an existing API instance or API Group instance, it is required to configure the SLA tier for the application and have one of the following roles or

permissions: Organization Administrator, API Manager Environment Administrator, or Manage Contracts permission. These roles or permissions allow managing client applications and contracts in API Manager.

Correct Answer: C

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.

Correct Answer: C

To create a new project that selects the correct API version and scaffolds the flows from the API specification, the developer should import a published API. This option allows importing an API specification that has been published to Anypoint Exchange or Design Center, and selecting a specific version of that API specification. The developer can also choose to scaffold flows based on that API specification. https://docs.mulesoft.com/ apikit.x/apikit-4-new-project-task

Correct Answer: A

A web API can use HTTP Webhook to notify its client of state changes as soon as they occur. A webhook is an HTTP callback that allows an API to send real-time notifications to another system or application when an event happens. The client registers a URL with the API where it wants to receive notifications, and then the API sends an HTTP request to that URL with information about the event. https://docs.mulesoft.com/connectors/webhook/webhook-connector

Correct Answer: E

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).

Correct Answer: C

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.

Correct Answer: C

To configure API Functional Monitoring to monitor the health of 10 public APIs periodically while minimizing operational overhead and cost, the developer should use one public location with all 10 APIs in a single schedule. A public location is a worker that runs in a CloudHub shared environment, which is cheaper and easier to maintain than a private location. A single schedule allows running all 10 APIs tests at the same time and frequency, which reduces complexity and resource consumption. https://docs.mulesoft.com/functional-monitoring/fm-create-monitor#create-a-monitor

Correct Answer: A

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.

Correct Answer: B

To run a test locally without the policies applied, the developer should create a properties file specifically for local development and set the API instance ID to a value that is not used in API Manager. This way, the developer can use different configuration properties for different environments and avoid triggering API autodiscovery when running tests locally. API autodiscovery is a mechanism that associates an API implementation with its corresponding API specification and policies in API Manager based on its API instance ID. By setting this ID to a value that does not exist in API Manager, the developer can prevent API autodiscovery from finding and applying any policies to the local test. https://docs.mulesoft.com/api-manager.x/api-auto-discovery-newconcept#configuring-api-autodiscovery https://docs.mulesoft.com/mule-runtime.3/configuringproperties
