AWS Certified Solutions Architect Professional SAP-C02 Practice Question

The correct answer provides the optimal combination of AWS Global Infrastructure components to meet all the specified requirements. The core application is deployed across multiple Availability Zones in the us-east-2 Region for high availability and fault tolerance. For the Chicago low-latency requirement, an AWS Local Zone is the ideal choice, as it is an extension of an AWS Region designed to run latency-sensitive applications closer to end-users in specific metropolitan areas. For the on-premises requirement in New York, an AWS Outpost is the correct solution. Outposts extend AWS infrastructure, services, APIs, and tools to a customer's data center, providing a consistent hybrid experience and meeting data residency needs. Finally, to deliver the static web interface globally with low latency and DDoS protection, Amazon CloudFront is the appropriate service, as it is a content delivery network (CDN) that uses a global network of Edge Locations to cache content closer to users.

• One incorrect option swaps the roles of AWS Local Zones and AWS Outposts. Outposts are for on-premises deployments, not for extending a region to a metro area, which is the function of a Local Zone.
• Another incorrect option suggests using an AWS Wavelength Zone. Wavelength Zones are designed for ultra-low-latency applications from 5G mobile devices and are embedded within telecommunication providers' 5G networks, which is not the requirement for the Chicago deployment.
• The final incorrect option proposes using a second VPC in a different region and AWS Direct Connect. A separate region will not meet the single-digit millisecond latency requirement for Chicago. While Direct Connect provides private network connectivity, it does not provide the capability to run AWS services and APIs on-premises; that is the specific purpose of AWS Outposts.
