Question
Which of the following describes an AWS Region?
A. A specific location within a geographical area that provides high availability
B. A collection of data centers that span multiple countries
C. A global view of a user’s cloud computing environment
D. A collection of databases that can be accessed only from a specific geographical area
Answer
A. A specific location within a geographical area that provides high availability
Explanation
An AWS Region is a specific location within a geographical area that provides high availability. An AWS Region consists of two or more Availability Zones, which are isolated locations within the same Region. Each Availability Zone has independent power, cooling, and physical security, and is connected to the other Availability Zones in the same Region via a low-latency, high-throughput, and highly redundant network. AWS services are available in multiple Regions worldwide, enabling the user to choose where to run their applications and store their data.
An AWS Region is a distinct geographic area where Amazon Web Services (AWS) clusters multiple data centers to deliver cloud services. Each region is designed to provide high availability, fault tolerance, and low latency for users in that area. Here’s why Option A is correct and why the other options are incorrect:
Why Option A Is Correct
Definition of a Region: An AWS Region consists of multiple, physically isolated data centers called Availability Zones (AZs). These AZs are interconnected through low-latency networks, ensuring high availability and fault tolerance.
Purpose: Regions allow customers to deploy applications closer to their end-users to reduce latency and comply with local regulations. By leveraging multiple AZs within a region, users can achieve high availability even if one AZ experiences disruptions.
Examples: Popular regions include US East (N. Virginia) and Asia Pacific (Tokyo), each offering services tailored to its geographical location.
Why Other Options Are Incorrect
Option B: “A collection of data centers that span multiple countries”
This is incorrect because AWS Regions are confined to specific geographic areas. While AWS operates globally, each region is localized and does not span multiple countries.
Option C: “A global view of a user’s cloud computing environment”
This describes the AWS Management Console or global services like IAM but not an AWS Region. Regions are isolated environments specific to geographic areas.
Option D: “A collection of databases that can be accessed only from a specific geographical area”
This is inaccurate because regions encompass much more than databases—they include compute, storage, networking, and other services. Additionally, resources in a region can often be accessed globally depending on configurations.
Key Features of AWS Regions
- Geographic Isolation: Each region is self-contained and independent to ensure fault isolation.
- High Availability: Regions consist of multiple AZs for redundancy and disaster recovery.
- Compliance & Data Residency: Regions help meet regulatory requirements like GDPR or HIPAA by allowing data to remain within specific jurisdictions.
- Performance Optimization: By choosing a region close to end-users, latency is minimized.
Understanding the concept of AWS Regions is critical for passing the AWS Certified Cloud Practitioner CLF-C02 exam as it forms the foundation of AWS’s global infrastructure strategy.
