Correct Answer: A

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. https://docs.mulesoft.com/muleruntime/4.3/deployment-strategies#readiness-probes

Correct Answer: C

When the HTTP Request operation raises an HTTP CONNECTIVITY error, it triggers an on-errorcontinue handler that sets a payload with "Error in processing your request'. Since no status code is explicitly set in this handler, it defaults to 500 (INTERNAL SERVER ERROR). Therefore, the web client receives an HTTP response with status code 500 and body "Error in processing your request'. https://docs.mulesoft.com/mule- runtime.3/error-handling#on-error-continue

Correct Answer: A

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. https://docs.mulesoft.com/objectstore/ osv2-faq#how-does-the-time-to-live-work

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

To use Maven to successfully deploy the application, the developer needs to modify the pom.xml file inside the Mule project. The pom.xml file contains the configuration and dependencies of the Mule application, as well as the deployment information such as the CloudHub region, environment, and worker size. The developer needs to specify these properties in the pom.xml file before using Maven to deploy the application. https:// docs.mulesoft.com/mule-runtime.3/mmpconcept# application-deployment-descriptor

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: D

To propagate the order ID as the correlation ID across each message using Anypoint MQ, the developer should wrap all Anypoint MQ Publish operations within a With CorrelationID scope from the Tracing module, setting the correlation ID to the order ID. The With CorrelationID scope allows setting a custom correlation ID for any event that occurs within it. The Tracing module also enables distributed tracing across different Mule applications and services using Anypoint Monitoring. https://docs.mulesoft.com/tracing-module.0/tracing- module-reference#withcorrelation-id-scope https://docs.mulesoft.com/tracing-module.0/tracing-module-concepts

Correct Answer: A

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. https:// docs.mulesoft.com/object-store/osv2-apis

Correct Answer: C

Based on the exhibit below, if "Insecure' is selected as part of the HTTP Listener configuration, the HTTP listener will only accept HTTP requests. This means that no TLS context will be configured for this listener and no encryption or

authentication will be applied to incoming requests. The protocol attribute of this listener will be set to HTTP instead of HTTPS.

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
