Question #1262
Which AWS components are foundational elements of the AWS global infrastructure? (Choose two.)
Availability Zones
AWS Wavelength
AWS Regions
Amazon CloudFront
AWS Direct Connect
Explanation
The correct answers are A (Availability Zones) and C (AWS Regions). AWS Regions are large geographic areas that contain multiple Availability Zones (AZs), which are isolated data centers with redundant power, networking, and connectivity. Together, Regions and AZs form the core of AWS's global infrastructure, enabling high availability, scalability, and fault tolerance.
Why other options are incorrect:
- B (AWS Wavelength): Part of AWS's edge computing solutions, not foundational infrastructure.
- D (Amazon CloudFront): A content delivery network (CDN) leveraging edge locations, which are supplementary to the core infrastructure.
- E (AWS Direct Connect): A network service for dedicated connections, not a foundational element.
Key Points:
- AWS global infrastructure is built on Regions and Availability Zones.
- Regions provide geographic separation, while AZs ensure fault tolerance within a Region.
- Other services (e.g., CloudFront, Direct Connect) enhance functionality but are not foundational.
Answer
The correct answer is: AC
