You plan to create a Network Load Balancing (NLB) cluster that will contain both servers.
You need to configure the network cards on the servers for the planned NLB configuration.
Solution: You configure the network cards to be on the same subnet and to have static IP addresses. You configure the cluster to use unicast.

  • B. No
Show Suggested Answer Hide Answer
Suggested Answer: A 🗳️
Following are the hardware requirements to run an NLB cluster.
✑ All hosts in the cluster must reside on the same subnet.
✑ There is no restriction on the number of network adapters on each host, and different hosts can have a different number of adapters.
✑ Within each cluster, all network adapters must be either multicast or unicast. NLB does not support a mixed environment of multicast and unicast within a single cluster.
✑ If you use the unicast mode, the network adapter that is used to handle client-to-cluster traffic must support changing its media access control (MAC) address.
Following are the software requirements to run an NLB cluster.
✑ Only TCP/IP can be used on the adapter for which NLB is enabled on each host. Do not add any other protocols (for example, IPX) to this adapter.
✑ The IP addresses of the servers in the cluster must be static.
