Explanation

* Organization should continue to use SCM system of their choice, in addition to keeping source code for these asset types in Anypoint Exchange, thereby enabling parallel development, branching.

* Reason is that Anypoint exchange is not full fledged version repositories like GitHub.

* But at same time it is tightly coupled with Mule assets

Explanation

* Mule High Availability Clustering provides basic failover capability for Mule. * When the primary Mule Runtime becomes unavailable, for example, because of a fatal JVM or hardware failure or it’s taken offline for maintenance, a backup Mule Runtime immediately becomes the primary node and resumes processing where the failed instance left off. * After a system administrator recovers a failed Mule Runtime server and puts it back online, that server automatically becomes the backup node. In this case, Alice, once up, will become backup ---------------------------------------------------------------------------------------------------------------------------------------------- Reference: So correct choice is : Files are polled form Bob node Bob is now the primary node

To design a caching strategy that queries the database only when there is an update to the Employees table, follow these steps:

• On Table Row Operation: Configure an On Table Row operation to monitor the Employees table for updates.
• Invalidate Cache: When the On Table Row operation detects an update, trigger the invalidate cache operation to clear the cache.
• Object Store Caching Strategy: Use an object-store-caching-strategy to store the cached responses.
• Default Expiration Interval: Use the default expiration interval for the cache, which ensures that cached data is invalidated based on the detection of changes in the Employees table rather than a fixed time interval.

This strategy ensures that the cache is only invalidated when there are actual changes in the Employees table, thereby minimizing redundant transactions and optimizing database performance.
