NEW QUESTION # 28
Which type of cache invalidation does the Cache scope support without having to write any additional code?
Answer: C
Explanation:
Mule's Cache scope is backed by a caching strategy, commonly using an Object Store. The caching strategy can directly configure expiration characteristics, including entry time to live (TTL). Once the TTL expires and the corresponding expiration processing occurs, cached entries are removed according to the configured Object Store policy without requiring application-specific invalidation logic.
MuleSoft's cache strategy documentation shows that the Object Store used by a caching strategy can define values such as entryTtl, expirationInterval, and maximum entries. A Cache component can then reference that strategy and automatically use those expiration settings.
Write-through and write-behind describe cache/database synchronization strategies in which cache updates are coordinated with writes to an underlying persistent data source. Mule's standard Cache scope does not automatically implement those patterns as an invalidation mode. Notification-based invalidation would similarly require external notification logic or explicit Mule processing to identify and invalidate affected keys.
TTL requires no such custom invalidation workflow. The developer establishes the lifetime when configuring the caching Object Store, after which Mule manages expiration automatically.
Therefore, Time to live is the cache invalidation mechanism directly available through standard Cache scope configuration.
Reference topics: Cache Scope; Object Store Caching Strategy; entryTtl; expirationInterval; automatic cache expiration.

NEW QUESTION # 29
Which statement is true when working with correlation IDS?
Answer: C
Explanation:
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.

NEW QUESTION # 30
A company has been using CI/CD. Its developers use Maven to handle build and deployment activities.
What is the correct sequence of activities that takes place during the Maven build and deployment?
Answer: C
Explanation:
The correct sequence of activities that takes place during the Maven build and deployment is validate, initialize, compile, test package, verify, install, deploy. These are Maven lifecycle phases that define a sequence of goals to execute during a build process. Each phase represents a stage in the build lifecycle and can have zero or more goals bound to it.

NEW QUESTION # 31
What is the MuleSoft recommended method to encrypt sensitive property data?
Answer: B
Explanation:
Secure property management should isolate development, test, staging, and production environments rather than allowing secrets from one environment to provide access to another. MuleSoft's Secure Configuration Properties model supports this by using environment-specific property files-for example dev.secure.yaml, sandbox.secure.yaml, and prod.secure.yaml-and resolving the appropriate file through an environment property.
Sensitive values such as passwords, API credentials, and private service configuration should therefore be environment-specific. Production credentials should not normally be reused in development or testing. The encryption key used to protect those values should likewise be independently managed rather than shared broadly across security boundaries. This limits the impact if a non-production key or properties file is exposed.
The Secure Properties Tool encrypts the sensitive values using a supplied key, while the Mule runtime receives the corresponding decryption key separately at deployment/runtime. MuleSoft also emphasizes protecting that key rather than embedding it directly in application configuration.
Accordingly, the Developer II security model represented by this question expects both different sensitive property values and different encryption keys across environments.
Reference topics: Secure Configuration Properties; environment-specific secure files; encryption keys; secret isolation; deployment security.

NEW QUESTION # 32
Refer to the exhibits.
BioInfo System API is implemented and published to Anypoint Exchange. A developer wants to invoke this API using its REST Connector.
What should be added to the POM?
Exhibit / Answer Configurations:
Answer: B
Explanation:
REST Connect converts a supported REST API specification published in Anypoint Exchange into a Mule 4 connector. MuleSoft states that REST Connect-generated Mule 4 connectors are produced as connector artifacts and can be used in Studio like other Mule connectors.
A Mule connector is consumed by an application through the project's Maven dependencies, not through the Maven build-plugin section. MuleSoft's standard connector Maven model requires the connector's Exchange groupId, artifactId, and version under < dependency > , together with:
< classifier > mule-plugin < /classifier >
The classifier is essential because it identifies the artifact as a Mule extension/plugin that the Mule runtime must load. MuleSoft's connector Maven documentation provides this exact dependency structure and directs developers to Exchange's Dependency Snippets for the current coordinates.
A < plugin > declaration is for Maven build plugins rather than runtime Mule connectors. < repository > merely defines where Maven can resolve artifacts and does not itself add the connector to the application. < rest-connect > is not the POM dependency element used to consume a generated connector.
Reference topics: REST Connect; Anypoint Exchange generated connectors; Maven dependencies; mule- plugin classifier.
