Read the first 7 AWS Networking and Content Delivery flashcards as text

  1. What is a subnet in Amazon VPC?

    Answer: A range of IP addresses within a VPC that resources are placed into, tied to a specific Availability Zone

    A subnet is a range of IP addresses in your VPC that spans a single Availability Zone, allowing you to place groups of isolated resources and control routing and access.

  2. Which Route 53 routing policy would you use to route traffic based on the lowest network latency for end users?

    Answer: Latency-based routing

    Latency-based routing directs traffic to the AWS Region that provides the lowest latency for the end user, improving application performance for globally distributed users.

  3. What is AWS Transit Gateway?

    Answer: A managed service that connects VPCs and on-premises networks through a central hub, simplifying the network topology

    AWS Transit Gateway acts as a cloud router and central hub to connect multiple VPCs and on-premises networks, replacing complex peering arrangements with a simpler hub-and-spoke model.

  4. What is the difference between a public subnet and a private subnet in a VPC?

    Answer: Public subnets have a route to an Internet Gateway allowing direct internet access, while private subnets do not

    A public subnet has a route table entry directing internet-bound traffic to an Internet Gateway, making resources directly reachable from the internet, while a private subnet has no such route.

  5. In Amazon CloudFront, what is an 'origin'?

    Answer: The server or AWS service (such as S3 or an ALB) where CloudFront fetches content to cache and distribute

    In CloudFront, an origin is the definitive source of content — such as an S3 bucket, an Application Load Balancer, or a custom HTTP server — from which CloudFront retrieves content to cache at edge locations.

  6. What is AWS PrivateLink?

    Answer: A technology that provides private connectivity between VPCs and services without exposing traffic to the public internet

    AWS PrivateLink provides private connectivity between VPCs, AWS services, and on-premises applications securely on the Amazon network, without exposing traffic to the public internet.

  7. Which AWS networking feature allows you to capture and inspect network traffic flowing to and from network interfaces in your VPC?

    Answer: VPC Flow Logs

    VPC Flow Logs capture information about IP traffic going to and from network interfaces in your VPC, enabling network monitoring, troubleshooting, and security analysis.
