What defines a public load balancer?

• A. Accessible only via private IP addresses
• B. Accepts traffic from the internet using a public IP
• C. Used exclusively for internal services
• D. Requires no external configuration

Answer: (B)

A public load balancer is defined by its ability to accept traffic from the internet using a public IP address. This capability enables it to distribute incoming traffic across multiple servers or instances, improving availability and reliability of services offered externally to users on the internet. Public load balancers are essential for managing external application traffic, allowing organizations to route requests to various backend servers based on the load, health of the servers, or in accordance with specific rules. By using a public IP, these load balancers can effectively communicate with clients over the internet and ensure that requests are met efficiently. In contrast, other options relate to different use cases or configurations that aren’t characteristic of a public load balancer. For instance, being accessible only via private IP addresses indicates a private load balancer, which is designed for internal network use. The option that mentions exclusive use for internal services also highlights a private infrastructure focus. Finally, the statement about requiring no external configuration is misleading, as setting up a public load balancer typically involves configuring it to interact appropriately with external clients and ensuring security measures are in place for remote access.
