CLF-C02 Question 147
Select 2A company is planning to deploy its application across multiple AWS Regions to ensure high availability and low latency for its users. Which AWS global infrastructure components should the company consider when designing this architecture?
- A
AWS Availability Zones
- B
AWS Edge Locations
- C
AWS Regions
- D
AWS Local Zones
- E
AWS Outposts
Show answer and explanation
Correct answers: A, C
Explanation
When designing an architecture for deployment across multiple AWS Regions, it is essential to consider AWS Regions and Availability Zones. AWS Regions provide geographically distinct locations for application deployment, while Availability Zones within those Regions ensure redundancy and fault tolerance. Edge Locations, Local Zones, and Outposts serve different purposes and are not directly relevant to multi-Region application deployment.
- A. Correct.
AWS Availability Zones are isolated locations within a Region that provide redundancy and fault tolerance for applications. They are critical for high availability within a Region but not across Regions.
- B. Incorrect.
AWS Edge Locations are part of the AWS global content delivery network (CDN) and are used for caching and delivering content closer to users. While they improve performance, they are not directly related to deploying applications across multiple Regions.
- C. Correct.
AWS Regions are geographic locations that consist of multiple Availability Zones. They are a key component of the AWS global infrastructure and are essential for deploying applications across multiple locations to achieve low latency and high availability.
- D. Incorrect.
AWS Local Zones are extensions of an AWS Region that allow customers to run latency-sensitive applications closer to their end-users. However, they are not relevant when considering multi-Region deployments.
- E. Incorrect.
AWS Outposts are physical servers that extend AWS infrastructure to on-premises data centers. They are not part of the AWS global infrastructure used for deploying applications across Regions.
