Question 37

A solutions architect is determining the best method for provisioning Internet connectivity for a data-processing application that will pull large amounts of data from an object storage system via the Internet. The solution must be redundant and have no constraints on bandwidth.

Which option satisfies these requirements?

  1. Deploy NAT instances in a public subnet.
  2. Use a NAT gateway.
  3. Create a VPC endpoint.
  4. Attach an Internet gateway.

Correct Answer: 4

Explanation: An Internet gateway is a horizontally scaled, redundant, and highly available VPC component that allows communication between your VPC and the Internet.

An Internet gateway serves two purposes: to provide a target in your VPC route tables for internet-routable traffic and to perform network address translation (NAT) for instances that have been assigned public IPv4 addresses.

An Internet gateway supports IPv4 and IPv6 traffic. It does not cause availability risks or bandwidth constraints on your network traffic.

INCORRECT: “Deploy NAT instances in a public subnet.” is incorrect. NAT instances are EC2 instances that are used, in a similar way to NAT gateways, by instances in private subnets to access the Internet. However, they are not redundant and are limited in bandwidth.

INCORRECT: “Use a NAT gateway.” is incorrect as a NAT gateway imposes a limit of 45 Gbps.

INCORRECT: “Create a VPC endpoint.” is incorrect. A VPC endpoint is used to access public services from a VPC without traversing the Internet.

CORRECT: “Attach an Internet gateway.” is the correct answer.
