AWS Certified Cloud Practitioner — Question 634
A company has set up a VPC in its AWS account and has created a subnet in the VPC. The company wants to make the subnet public.
Which AWS features should the company use to meet this requirement? (Choose two.)
Answer options
- A. Amazon VPC internet gateway
- B. Amazon VPC NAT gateway
- C. Amazon VPC route tables
- D. Amazon VPC network ACL
- E. Amazon EC2 security groups
Correct answer: A, C
Explanation
To configure a subnet as public, you must attach an Amazon VPC internet gateway to the VPC and add a route in the Amazon VPC route tables that directs internet-bound traffic (0.0.0.0/0) to the internet gateway. A NAT gateway is used to provide internet access to private subnets, while security groups and network ACLs are firewalls used for security filtering rather than routing traffic to the internet.
