Which action should be taken to accomplish this?
Add a second NAT instance and place both instances behind a load balancer
Convert the NAT instance to a larger instance size
Replace the NAT instance with a NAT gateway
Replace the NAT instance with a virtual private gateway
Explanations:
Adding a second NAT instance behind a load balancer does not improve scalability or cost-effectiveness. It introduces additional complexity and may not resolve the underlying latency issue.
Increasing the size of the NAT instance may temporarily reduce latency, but it is not scalable or cost-efficient as traffic grows. Larger instances incur higher costs and lack auto-scaling.
Replacing the NAT instance with a NAT gateway is a scalable, cost-effective solution. NAT gateways provide better performance, automatic scaling, and lower management overhead.
Replacing the NAT instance with a virtual private gateway does not address the latency issue. Virtual private gateways are used for connecting to on-premises networks, not internet access.
If I had to guess, I’d say the answer is:
Replace the NAT instance with a NAT gateway
I compute that the answer is:
Replace the NAT instance with a NAT gateway
