AWS AWS Networking and Content Delivery 1 — Questions and Answers
Question 1: What is Amazon VPC?
- A logically isolated section of the AWS Cloud where you can launch AWS resources in a virtual network you define (Correct answer)
- A virtual private server for running applications
- A VPN connection between on-premises and AWS
- A content delivery network service
Correct answer: A logically isolated section of the AWS Cloud where you can launch AWS resources in a virtual network you define
Amazon VPC (Virtual Private Cloud) lets you provision a logically isolated virtual network in AWS where you control IP addressing, subnets, routing, and security.
Question 2: What is the difference between a public subnet and a private subnet in a VPC?
- A public subnet has a route to an Internet Gateway; a private subnet does not (Correct answer)
- A public subnet is available to all AWS accounts; a private subnet is account-specific
- A public subnet has no security groups; a private subnet does
- A public subnet uses IPv6; a private subnet uses IPv4
Correct answer: A public subnet has a route to an Internet Gateway; a private subnet does not
A public subnet has a route table entry pointing to an Internet Gateway, allowing resources to communicate directly with the internet, while private subnets lack this route.
Question 3: Which AWS service acts as a DNS web service for routing end users to internet applications?

Amazon CloudFront is a fast CDN service that securely delivers data, videos, and applications to customers globally via edge locations.
Question 5: What is an Internet Gateway in AWS VPC?
- A VPC component that enables communication between a VPC and the internet (Correct answer)
- A NAT device for private subnets
- A firewall for VPC traffic
- A dedicated connection to on-premises networks
Correct answer: A VPC component that enables communication between a VPC and the internet
An Internet Gateway is a horizontally scaled, redundant VPC component that allows communication between instances in your VPC and the internet.
