Salesforce Mule-Dev-301 : Salesforce Certified MuleSoft Developer II

Which statement is true when working with correlation IDs?

• A. The HTTP Listener regenerates correlation IDs regardless of the HTTP request
• B. The Anypoint MQ Connector automatically propagates correlation IDs
• C. The HTTP Listener generates correlation IDs unless a correlation ID is received in the HTTP request
• D. The VM Connector does not automatically propagate correlation IDs

Which statement is true when using XML SDK for creating custom message processors?

• A. Operations can be reused in recursive calls
• B. All operations are public
• C. 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
• D. An XML SDK provides both inbound and outbound operations

A developer deploys an API to CloudHub and applies an OAuth API policy in API Manager. During testing, the API response is slow, so the developer reconfigures the API so that the out-of-the-box HTTP Caching policy is applied first, and the OAuth API policy is applied second.
What will happen when an HTTP request is received?

• A. In case of a cache miss, only the HTTP Caching policy is evaluated; then the API retrieves the data from the API implementation, and the policy stores the data to be cached in Object Store
• B. In case of a cache miss, both the OAuth and HTTP Caching policies are evaluated; then the API retrieves the data from the API implementation, and the policy does not store the data in Object Store
• C. In case of a cache hit, only the HTTP Caching policy is evaluated; then the cached response is returned to the caller
• D. In case of a cache hit, both the OAuth and HTTP Caching policies are evaluated; then the cached response is returned to the caller

Refer to the exhibit.
What required changes can be made to give a partial successful response in case the United Airlines API returns with a timeout?
Exhibit:

• A. Add a Scatter-Gather component inside a Try Scope. Set the payload to a default value "Error" inside the error handler using the On Error Propagate scope.
• B. Add a Scatter-Gather component inside a Try Scope. Set the payload to a default value "Error" inside the error handler using the On Error Continue scope.
• C. Add Flow Reference components inside a Try scope. Set the payload to a default value "" inside the error handler using the On Error Continue scope.
• D. Add Flow Reference components inside a Try Scope. Set the payload to a default value "" inside the error handler using the On Error Propagate scope.

Refer to the exhibits.
The
flow is invoking a target API. The API's protocol is HTTPS. The TLS configuration in the HTTP Request Configuration global element is set to None. A web client submits a request to http://localhost:8081/vehicles.
If the certificate of the target API is signed by a certificate authority (CA), what is true about the HTTP Request operation when the flow executes?
Exhibit:

• A. The HTTP Request operation will always succeed regardless of the CA
• B. The HTTP Request operation will succeed if the CA's certificate is present in the JRE's default keystore
• C. The HTTP Request operation will succeed if the CA's certificate is present in the JRE's default truststore
• D. The HTTP Request operation will always fail regardless of the CA
