Final answer:
The correct order from most to least in number is Edge Locations, Availability Zones, and then Regions, which relates to the structure of cloud computing networks.
Step-by-step explanation:
When comparing the number of Availability Zones, Regions, and Edge Locations in cloud computing networks such as Amazon Web Services (AWS), the correct hierarchical order, from the largest to the smallest number, is: c. # of Edge Locations > # of Availability Zones > # of Regions.
This means that there are more edge locations worldwide to ensure lower latency for end users by caching content closer to the user’s location, followed by availability zones which are isolated locations within each region that provide redundancy and fault tolerance. Lastly, regions are geographical areas that consist of two or more availability zones.
