AWS Certified Solutions Architect – Professional — Question 354

Your supervisor has given you the task of creating an elastic network interface on each of your web servers that connect to a mid-tier network where an application server resides. He also wants this set up as a Dual-homed Instance on Distinct Subnets. Instead of routing network packets through the dual-homed instances, where should each dual-homed instance receive and process requests to fulfil his criteria?

Answer options

• A. On one of the web servers
• B. On the front end
• C. On the back end
• D. Through a security group

Correct answer: B

Explanation

In a dual-homed instance configuration on distinct subnets, the instance is intended to receive and process requests on the front end rather than routing network packets between the subnets. This setup ensures that public-facing traffic is handled directly at the entry point of the network architecture. Other options like processing on the back end or utilizing a security group do not represent the correct architectural flow for handling dual-homed instance requests.
