Oracle Cloud Infrastructure 2020 Architect Associate — Question 12

You have an Oracle Cloud Infrastructure (OCI) load balancer distributing traffic via an evenly-weighted round robin policy to your back-end web servers. You notice that one of your web servers is receiving more traffic than other web servers.
How can you resolve this to make sure traffic is evenly distributed across all back-end webservers?

Answer options

• A. Disable cookie-based session persistence on your backend set.
• B. Change keep-alive setting between the load balancer and backend server.
• C. Disable SSL configuration associated with your backend set.
• D. Create separate listeners for each backend web server.

Correct answer: A

Explanation

The correct answer is A because disabling cookie-based session persistence ensures that subsequent requests from a client do not always go to the same backend server, promoting even distribution of traffic. The other options do not directly address the issue of traffic distribution; changing the keep-alive settings, SSL configurations, or creating separate listeners may not resolve the imbalance caused by session persistence.
