Correct Answer: C,D
Explanation/Reference: Explanation: C: Autoscale is a built-in feature of Cloud Services, Mobile Services, Virtual Machines, and Websites that helps applications perform their best when demand changes. Of course, performance means different things for different applications. Some apps are CPU-bound, others memory-bound.

D: Blobs that benefit the most from Azure CDN caching are those that are accessed frequently during their time-to-live (TTL) period. A blob stays in the cache for the TTL period and then is refreshed by the blob service after that time is elapsed. Then the process repeats.
