A new Mule project has been created in Anypoint Studio with the default settings.
Which file inside the Mule project must be modified before using Maven to successfully deploy the application?
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. Reference: https://docs.mulesoft.com/mule-runtime/4.3/mmp-concept#application-deployment-descriptor
Which type of cache invalidation does the Cache scope support without having to write any additional code?
The Cache scope supports time to live (TTL) as a cache invalidation strategy without having to write any additional code. TTL specifies how long the cached response is valid before it expires and needs to be refreshed. The Cache scope also supports custom invalidation strategies using MEL or DataWeave expressions. Reference: https://docs.mulesoft.com/mule-runtime/4.3/cache-scope#cache_invalidation
Which command is used to convert a JKS keystore to PKCS12?
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). Reference: https://docs.oracle.com/en/java/javase/11/tools/keytool.html#GUID-5990A2E4-78E3-47B7-AE75-6D1826259549
What is the MuleSoft recommended method to encrypt sensitive property data?
The MuleSoft recommended method to encrypt sensitive property data is to use the Secure Properties Tool that comes with Anypoint Studio. This tool allows encrypting properties files with a secret key and then decrypting them at runtime using the same key. The encryption key and sensitive data should be different for each environment to ensure security and avoid accidental exposure of sensitive data. Reference: https://docs.mulesoft.com/mule-runtime/4.3/secure-configuration-properties
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?
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
