Both CDN and Dispatcher can be used to cache content, but in addition to that, both provide some specific functionality.

CDN can be globally distributed and serves requests across balanced regions while the dispatcher resides with AEM. CDN's main purpose is to reduce latency by delivering cacheable content from the CDN nodes at the edge, near the browser. On the other hand, the dispatcher is also used as a load balancer.

      @pallavi223 That's an interesting question. Please read here why caching at CDN can be done in addition to the dispatcher.  So is it mandatory- No, does it help improve performance further-yes
