Virtual Private Cloud Quiz
A data processing application in AWS must pull data from an Internet service. A Solutions Architect is to design a highly available solution to access this data without placing bandwidth constraints on the application traffic.
Which solution meets these requirements?
A. Launch a NAT gateway and add routes for 0.0.0.0/0
B. Attach a VPC endpoint and add routes for 0.0.0.0/0
C. Attach an Internet gateway and add routes for 0.0.0.0/0
D. Deploy NAT instances in a public subnet and add routes for 0.0.0.0/0
C. Attachan Internet gateway and add routes for 0.0.0.0/0
The AWS Documentation mentions the following:
An Internet gateway is a horizontally scaled, redundant, and highly available VPC component that allows communication between instances in your VPC and the Internet. It therefore imposes no availability risks or bandwidth constraints on your network traffic.
For more information on the Internet gateway, please visit the following URL:

Note: NAT gateway is also a highly available architecture and is used to enable instances in a private subnet to connect to the internet or other AWS services, but prevent the internet from initiating a connection with those instances.
It can only scale up to 45 Gbps.
NAT instances’s bandwidth capability depends up on the instance type.
VPC Endpoints are used to enable private connectivity to services hosted in AWS, from within your VPC without using an Internet Gateway, VPN, Network Address Translation (NAT) devices, or firewall proxies. So it cannot be used to connect to internet.
An Internet gateway is horizontally-scaled, redundant, and highly available. It imposes no bandwidth constraints.
