Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.
After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
You have two servers that run Windows Server 2016.
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 multicast.
Does this meet the goal?

  • A. Yes
  • 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.

Hello Guys , in this answer column it says: "NLB does not support a mixed environment of multicast and unicast within a single cluster". By mixed environment ,does it only mean an environment which has Windows OS and Non-Windows OS, or does it also include an enviornment where their are computers having different hardwares from different hardware vendors ? Pls correct me If I am wrong

I want to inform everyone that as of March 2019, the 740 exam has been updated. The questions are these that you will find on exam, but be careful because the reference version is 1809 and not 1607. So pay attention to the answers you will give. For the common and personal good, the questions should be carefully studied. Thank you all for this community
