Correct answer is A, modify the port rules. To change the affinity setting to single. This will allow session data to be maintained with the clients. https://www.omnisecu.com/windows-2003/clustering/network-load-balancing-nlb-client-affinity-and-port-onfiguration.php#:~:text=Client%20affinity%20can%20be%20configured,client%20to%20the%20same%20server.

I seem to agree, following the link provided with the site listed answer, modes of operation has no effect on redirecting single user to the same server maintaining the session, unlike the link you provided regarding prot rules.

I agree with members who say A is correct. What I should understand is that Affinity is included in Port Rule. Though I don't know for detail, OS controls Affinity by Port Rule. My understand is that operation modes(unicast/multicast) are used between nodes.and that affinity is used between client and cluster.

This is about an affinity rule. The Single Affinity rule should be set, by modifying the Port Rule. This will still allow load balancing between both NLB hosts, while a single user will always be sent to the same host. Changing the port rule will not affect the load balancing between the nodes. the correct answer is A - edit the port rule.
