Which OCI service would you use to distribute incoming traffic between a set of web servers?

The Public Load Balancer is the correct choice for distributing incoming traffic among a set of web servers in Oracle Cloud Infrastructure (OCI). This service is designed to handle and manage network traffic seamlessly. It acts as a single entry point for the incoming requests from users and intelligently distributes those requests across multiple backend servers, ensuring high availability and reliability.

Using a Public Load Balancer provides several advantages, such as automatic scaling, health monitoring of the backend web servers, and the ability to maintain session persistence if necessary. This means that users can experience a consistent and reliable interaction with the web application, even if some servers are down or during heavy traffic periods.

In contrast, a Virtual Cloud Network is primarily focused on networking constructs and does not handle traffic distribution directly. An Instance Pool groups instances for scaling and management purposes but does not perform load balancing by itself. Lastly, a Route Table is used to route traffic between different subnets and does not have functionality related to load balancing or traffic distribution.
