AWS Certified Cloud Practitioner — Question 683

Which AWS service or feature provides high availability and low latency within an AWS Region?

Answer options

• A. Edge locations
• B. Availability Zones
• C. AWS Outposts
• D. Amazon Route 53

Correct answer: B

Explanation

Availability Zones are physically distinct, isolated locations within an AWS Region that are connected through low-latency, high-throughput redundant networking to ensure high availability. Edge locations are used for global content delivery via CloudFront rather than intra-region availability, while AWS Outposts is for on-premises deployments and Amazon Route 53 is a global DNS service.
