• Question 1380:

  Which AWS service or feature can provide the EC2 instances with network connections to the internet?

  A. Gateway endpoint
  B. NAT gateway
  C. Network Load Balancer
  D. Amazon Route 53
  B. NAT gateway

  ---

  Explanation/Reference:

  B. NAT gateway

  A NAT (Network Address Translation) gateway allows instances in a private subnet to access the Internet, but prevent the Internet from initiating a connection with those instances. A NAT gateway forwards traffic from instances in the private

  subnet to the Internet, and then routes the response back to the instances. This way, instances in the private subnet can access the Internet to download software updates, retrieve application data and perform other tasks, while remaining

  isolated from incoming Internet traffic, providing a more secure network environment.

  It's important to note that a NAT gateway is a horizontally scalable, redundant, and highly available VPC component that automatically replaces failed NAT gateways.
