Difficulty: EasyAWS Global Infrastructure

When designing applications, understanding how AWS structures its global infrastructure is essential. Which of the following statements correctly describe the characteristics of AWS Regions and Availability Zones? (Select TWO.)

  1. Each Availability Zone is composed of one or more physical data centers with redundant power, networking, and connectivity.Answer
  2. An AWS Region is an independent geographic area that contains multiple, physically isolated Availability Zones.Answer
  3. C
    A single Availability Zone is geographically distributed across multiple AWS Regions to provide global disaster recovery.
  4. D
    Edge Locations are used to host the primary compute instances and database workloads within a Region.
  5. E
    All Availability Zones within a Region share the same physical power grid infrastructure to minimize setup costs.

Answer

Each Availability Zone is composed of one or more physical data centers with redundant power, networking, and connectivity; and an AWS Region is an independent geographic area that contains multiple, physically isolated Availability Zones.
The correct statements accurately define the AWS Global Infrastructure hierarchy: an AWS Region is a geographic area that houses multiple, isolated Availability Zones, and each Availability Zone is composed of one or more physical data centers with independent power, cooling, and network links.

Step-by-Step Solution

1
Analyze the definition of an Availability Zone (AZ).
An AZ is defined as one or more discrete data centers with redundant infrastructure within an AWS Region.
This helps identify the first correct statement.
2
Analyze the definition of an AWS Region.
An AWS Region is a geographic area containing multiple isolated AZs.
This helps identify the second correct statement.
3
Evaluate and rule out the incorrect infrastructure component relationships.
AZs do not span multiple regions, Edge Locations are for content delivery rather than hosting databases/servers, and AZs do not share power grids.
This confirms the correctness of the chosen options.

Key Concept

AWS Regions and Availability Zones are the core components of the AWS Global Infrastructure, designed to provide high availability and isolation.
