[All MuleSoft Integration Architect I Questions]

An external API frequently invokes an Employees System API to fetch employee data from a MySQL database. The architect must design a caching strategy to query the database only when there Is an update to the Employees table or else return a cached response in order to minimize the number of redundant transactions being handled by the database.

AUse an On Table Row operation configured with the Employees table, call invalidate cache, and hardcode the new Employees data to cache. Use an object-store-caching-strategy and set the expiration interval to 1 hour.

BUse an On Table Row operation configured with the Employees table and cail invalidate cache. Use an object-store-caching-strategy and the default expiration interval.

CUse a Scheduler with a fixed frequency set to every hour to trigger an invalidate cache flow. Use an object-store-caching-strategy and the default expiration interval.

DUse a Scheduler with a fixed frequency set to every hour, triggering an invalidate cache flow. Use an object-store-caching-strategy and set the expiration interval to 1 hour.

This question is a real head-scratcher. I'm just hoping I don't end up 'caching' my career if I get it wrong!

I think option A sounds like the best approach to minimize redundant transactions and keep the data fresh.

Hmm, this question is a real brain-teaser. I'm going to go with option D - it seems the most robust and reliable solution.

C is a nice compromise, but I'd rather not rely on a scheduled job to invalidate the cache. Seems like a potential point of failure.

A is a bit overkill, don't you think? Hardcoding the data feels like a hack, and 1 hour is too long for a cache expiration.

D is the best choice here. Scheduled invalidation with a 1-hour expiration interval ensures the cache is up-to-date without unnecessary database queries.

Option B seems like the way to go. Keep it simple and let the default expiration interval handle the caching.
