# 1z0-1072-20 — Question 602

**Type:** multiple_choice
**Topics:** topic_1

## Question

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?

## Correct Answer

_See scenario._

## Explanation

A is correct.
Session persistence is a method to direct all requests originating from a single logical client to a single backend web server. You enable session persistence when you create a load balancer or when you create a backend set. You can also edit an existing backend set to enable, disable, or change the session persistence configuration.

The listener is defined per traffic type, not per individual backend server.
