DEX660 Sample Exam Questions and Answers
| QUESTION: 1 |
| An organization uses CloudHub to deploy all of its applications.How can a common-global-handler flow be configured so that it can be reused across all of the organization’sdeployed applications? Option A: Create a Mule plugin project Create a common-global-error-handler flow inside the plugin project. Use this plugin as a dependency in all Mute applications. Import that configuration file in Mute applications. Option B: Create a common-global-error-handler flow in all Mule Applications Refer to it flow-ref wherever needed. Option C: Create a Mule Plugin project Create a common-global-error-handler flow inside the plugin project. Use this plugin as a dependency in all Mule applications Option D: Create a Mule daman project. Create a common-global-error-handler flow inside the domain project. Use this domain project as a dependency. |
| Correct Answer: C |
| Explanation/Reference: To configure a common-global-handler flow that can be reused across all of the organization’s deployed applications, the developer should create a Mule Plugin project, create a common-global-error-handler flow inside the plugin project, and use this plugin as a dependency in all Mule applications. This way, the developer can import the common-global-error-handler flow in any application that needs it and avoid duplicating the error handling logic. References: https://docs.mulesoft.com/mule-runtime/4.3/error-handling#global-error-handler |
| QUESTION: 2 |
| When implementing a synchronous API where the event source is an HTTP Listener, a developer needs toreturn the same correlation ID back to the caller in the HTTP response header.How can this be achieved? Option A: Enable the auto-generate CorrelationID option when scaffolding the flow Option B: Enable the CorrelationID checkbox in the HTTP Listener configuration Option C: Configure a custom correlation policy Option D: NO action is needed as the correlation ID is returned to the caller in the response header by default |
| Correct Answer: D |
| Explanation/Reference: When implementing a synchronous API where the event source is an HTTP Listener, Mule automatically propagates some message attributes between flows via outbound and inbound properties. One of these attributes is correlation ID, which is returned to the caller in the response header by default as MULE_CORRELATION_ID. References: https://docs.mulesoft.com/mule-runtime/4.3/about-mule-message#message-attributes |
| QUESTION: 3 |
| A Mule application deployed to a standardalone Mule runtime uses VM queues to publish messages to beconsumed asynchronously by another flow.In the case of a system failure, what will happen to in-flight messages in the VM queues that have beenconsumed? Option A: For nay type of queue, the message will be processed after the system comes online Option B: For persistent queues, the message will be processed after the system comes online Option C: For transient queues, the message will be processed after the system comes online Option D: For any type of queue, the message will be lost |
| Correct Answer: B |
| QUESTION: 4 |
| A developer deploys an API to CloudHub and applies an OAuth policy on API Manager. During testing, theAPI response is slow, so the developer reconfigures the API so that the out-of-the-box HTTP Caching policyis applied first, and the OAuth API policy is applied second.What will happen when an HTTP request is received? Option A: In case of a cache hit, both the OAuth and HTTP Caching policies are evaluated; then the cached response is returned to the caller Option B: In case of a cache it, only the HTTP Caching policy is evaluating; then the cached response is returned to the caller Option C: 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 Option D: 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 |
| Correct Answer: B |
| Explanation/Reference: When an HTTP request is received and the HTTP Caching policy is applied first, it checks if there is a cached response for that request in Object Store. If there is a cache hit, meaning that a valid cached response exists, then only the HTTP Caching policy is evaluated and the cached response is returned to the caller without invoking the OAuth policy or the API implementation. If there is a cache miss, meaning that no valid cached response exists, then both the HTTP Caching policy and the OAuth policy are evaluated before invoking the API implementation.

| QUESTION: 5 |
| 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? Option A: Create a health check endpoint that listens on a separate port and uses a separate HTTP Listener configuration from the API Option B: Configure the application to send health data to an external system Option C: Create a health check endpoint that reuses the same port number and HTTP Listener configuration as the API itself Option D: Monitor the Payment API directly sending real customer payment data |
| Correct Answer: A |
| Explanation/Reference: 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.
