Question

Options

Explanation

Caching in AEM Cloud Service stores frequently accessed content (pages, assets, API responses) closer to the user - in CDN layers or the Dispatcher - so repeated requests are served without hitting the origin server, directly reducing server load and response times (B is correct). Option A is wrong because caching is designed to store useful data strategically, not arbitrary unnecessary data - the whole point is to avoid redundant processing. Option C ignores the well-documented performance gains from CDN and Dispatcher caching, which are foundational to AEM's architecture. Option D inverts reality - caching simplifies performance optimization by offloading work from the publish tier, rather than complicating it.

Memory tip: Think of caching as a "shortcut shelf" - instead of fetching ingredients from the back of the warehouse every time, you keep the most-used ones at the counter. Less trips = faster service = reduced load. In AEM, the CDN and Dispatcher are that shelf.
