Each option can solve part of the scenario. The exam expects you to choose the one that satisfies the stated constraints with the right operational burden, security boundary, availability model, and cost behavior.
Key Differences
| Option | Primary model | Best use | Security | Availability | Operations and cost |
|---|---|---|---|---|---|
| CloudFront | HTTP/HTTPS caching and edge delivery | Static/dynamic web content, S3/ALB/API origins | WAF, signed URLs, OAC | Global edge network; origin failover options | Cache and request pricing; configure behaviors and invalidation |
| Global Accelerator | Anycast edge ingress to regional endpoints | TCP/UDP apps, static anycast IPs, multi-Region endpoint failover | Endpoint weights and health checks | Health-based endpoint failover across Regions | Hourly accelerator and data-processing cost; no content caching |
