In this lesson

Prepare for the SAA-C03 exam (AWS Certified Solutions Architect – Associate). In this lesson: NAT gateways and NAT instances, one shared NAT gateway or one per zone, gateway endpoints, data transfer charges between zones and Regions, VPC peering, Transit Gateway, and Route 53 alias records, the internet, VPN, or Direct Connect, and bandwidth, CloudFront, and throttling strategies. Includes three original practice questions.

Preview the topics
  • Instances in private subnets copy 50 TB a month to S3 in the same Region through a NAT gateway, and the NAT processing charge keeps growing. What should the architect do?
  • The data center exchanges hundreds of terabytes a month with AWS over VPN tunnels, which are saturated, with performance that varies through the day. What should the architect choose?
  • Product photos in one S3 bucket are downloaded by millions of users around the world, and data transfer out is now the largest network charge. What should the architect do?
