Practice Test 3 | AWS Certified Solutions Architect Associate | SAA-C03 | Dumps | Mock Test
Your infrastructure in AWS currently consists of a private and public subnet. The private subnet consists of database servers and the public subnet has a NAT Instance which helps the instances in the private subnet to communicate with the Internet. The NAT Instance is now becoming a bottleneck. Which of the following changes to the current architecture can help prevent this issue from occurring in the future?
A. Use a NAT Gateway instead of the NAT Instance.
B. Use another Internet Gateway for better bandwidth.
C. Use a VPC connection for better bandwidth.
D. Consider changing the instance type for the underlying NAT Instance.
Explanation:
Answer – A
The NAT Gateway is a managed resource which can be used in place of a NAT Instance. While you can consider changing the instance type for the underlying NAT Instance, this does not guarantee that the issue will not reoccur in the future.
