Final answer:
To specify the types of traffic an NLB cluster should respond to, you need to configure port rules. These rules determine the IP address, port range, and protocols for the cluster's response, ensuring traffic is handled correctly for high availability and scalability.
Step-by-step explanation:
In an Network Load Balancing (NLB) cluster, to specify the types of traffic the cluster should respond to, you should configure the port rules. Port rules determine how network traffic will be filtered and handled by the cluster. They define the IP address range, the port range, and the protocol to which the cluster nodes will respond. Additionally, port rules can specify the load weight for load balancing, the priority for failover situations, and the filtering mode which can be set to multiple host, single host, or disabled.
For example, if you want your NLB cluster to handle HTTP traffic, you would configure a port rule that specifies TCP port 80. If you're setting up a cluster for HTTPS traffic, then you would use TCP port 443. It's essential to configure these port rules carefully to ensure the NLB cluster directs traffic correctly and offers high availability and scalability for the applications it supports.
