3Edge and DNS Design

Practice questions →Glossary →
  • 3.1Route 53 and Routing Policies

    Route smartly with DNS—understand Route 53, latency/geolocation/weighted/failover routing, health checks, and alias records. Pick the policy that fits the goal.

  • 3.2Content Delivery with CloudFront

    Fast and secure at the edge—understand CloudFront, caching, origins (S3/ALB), origin protection with OAC, and TLS/WAF at the edge. Deliver with low latency from edges worldwide.

  • 3.3Global Accelerator and Choosing Edge Services

    The other edge—understand Global Accelerator, static anycast IPs, the AWS backbone, fast regional failover, and how it differs from CloudFront. Choose it for non-HTTP or static-IP needs.
