Oracle Cloud Infrastructure 2019 Developer Associate — Question 9

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

Answer options

• A. Check security lists and route tables of your virtual cloud network (VCN) and fix any issues associated with the rules
• B. Create separate listeners for each backend web server
• C. Delete and re-create your OCI load balancer
• D. Disable session persistence on your backend set

Correct answer: A

Explanation

The correct answer is A because checking the security lists and route tables can reveal misconfigurations that may lead to uneven traffic distribution. Options B and C do not address the underlying cause of the traffic imbalance, and option D would generally lead to a loss of session affinity, which may not solve the problem at hand.
