Answer - A - Network Load Balancing supports a maximum of 32 nodes.

Key Takeaway: Network Load Balancing Services, or NLBS, is a proprietary Microsoft implementation of clustering and load balancing that is intended to provide high availability, reliability, and scalability. It is intended for applications with relatively small data sets that do not change frequently and do not have long-running in-memory states. An interesting feature with NLBS is that all servers in a cluster examine each other with a heartbeat signal. This avoids a single point of failure. The maximum number of nodes supported with NLB is 32.
