Salesforce MuleSoft-Integration-Architect-I Exam With Confidence Using Practice Dumps

To achieve efficient caching and reduce redundant database transactions, the following strategy can be implemented:

On Table Row Listener: Implement an "On Table Row" trigger on the employees' table. This trigger will monitor changes (inserts, updates, deletes) in the employee records.

Invalidate Cache: Upon detecting changes in the employees' table, the trigger will call a flow to invalidate the current cache.

Object Store for Caching: Utilize MuleSoft's object store to cache the employee data. This store can hold the data for quick retrieval.

Set Expiration Interval: Configure the expiration interval for the cached data to ensure it is cleared when necessary. For this scenario, since we are invalidating cache on actual data changes, setting the expiration interval to empty can be suitable.

Return Cached Data: If there are no updates, the cached response is returned, reducing database load.

Caching Strategies

Explanation

* Object Store and VM Store is used for sharing data inter or intra mule applications in same setup. Can't be used with external Business Partner

* Also File connector will not be useful as the two companies currently have no shared IT infrastructure. It's specific for local use.

* Correct answer is SFTP connector. The SFTP Connector implements a secure file transport channel so that your Mule application can exchange files with external resources. SFTP uses the SSH security protocol to transfer messages. You can implement the SFTP endpoint as an inbound endpoint with a one-way exchange pattern, or as an outbound endpoint configured for either a one-way or request-response exchange pattern.

Explanation

V2 Rest API is recommended for on premise applications to access Object Store. It also comes with overhead of encryption and security of using rest api. With Object Store v2, the API call is localized to the same data center as the Runtime Manager app.

But in this case requirement is to access the OS of other mule application and not the same mule application.

You can configure a Mule app to use the Object Store REST API to store and retrieve values from an object store in another Mule app.

However, Object Store v2 is not designed for app-to-app communication.
