AWS Certified Cloud Practitioner (CLF-C02) — Question 41

Which AWS service helps deliver highly available applications with fast failover for multi-Region and Multi-AZ architectures?

Answer options

• A. AWS WAF
• B. AWS Global Accelerator
• C. AWS Shield
• D. AWS Direct Connect

Correct answer: B

Explanation

AWS Global Accelerator is the correct answer because it optimizes the path to your application, ensuring fast failover and improved availability across multiple Regions and Availability Zones. AWS WAF is a web application firewall, AWS Shield provides DDoS protection, and AWS Direct Connect is used for establishing a dedicated network connection, none of which directly provide the same level of application availability and failover capabilities.
