The correct answer is B. Client IP. This option ensures that all traffic from the same client IP is consistently directed to the same backend instance, providing session stickiness based solely on the client’s IP address. Since the question does not specify the need to differentiate between HTTP or TFTP services, Client IP affinity is sufficient to meet the requirement for sticky sessions. Therefore, B offers the simplest and most efficient solution for your use case.
D, Client IP only is a good starting point but insufficient when dealing with multiple services on different ports which is why its crucial to include both port and protocol
B. Client IP In the context of session affinity, selecting "Client IP" means that the load balancer uses the client's IP address to determine which backend instance should receive the traffic. Each unique client IP is consistently directed to the same backend instance. If you are looking for stickiness based on the client's IP address only, and you don't need to consider the specific protocol (HTTP or TFTP), then option B is appropriate. So, if the requirement is solely to maintain stickiness based on the client IP and the protocol (HTTP or TFTP) doesn't need to be considered, then option B is indeed the correct choice. I appreciate your clarification, and I hope this provides a clear explanation.
