Which statements accurately describe the relationships among components of AWS global infrastructure? (Choose two.)

Question

Options

• AThere are more AWS Regions than Availability Zones.
• BThere are more edge locations than AWS Regions.
• CAn edge location is an Availability Zone.
• DThere are more AWS Regions than edge locations.
• EThere are more Availability Zones than AWS Regions.

• A
  2% (1)
• B
  93% (42)
• C
  4% (2)

Explanation

AWS Global Infrastructure Relationships

B and E are correct because AWS has hundreds of edge locations (Points of Presence) worldwide - far more than its dozens of Regions - making B accurate, and since each Region contains a minimum of 2-3 Availability Zones (AZs), there are always more AZs than Regions, making E accurate.

Why the distractors are wrong:

• A is the opposite of reality - there are more AZs than Regions, not more Regions than AZs
• C is incorrect because edge locations and AZs are entirely different concepts - edge locations serve content delivery (CloudFront/Route 53), while AZs are isolated data center clusters for deploying services
• D is backwards - there are far more edge locations (400+) than Regions (30+), not the other way around

Memory tip: Think of it as a pyramid from largest to smallest count: Edge Locations > AZs > Regions. Edge locations are like retail storefronts (everywhere), AZs are like distribution centers (several per city/region), and Regions are like corporate headquarters (fewest in number). This hierarchy - E > AZ > R - will help you quickly answer any infrastructure relationship question on the exam.
