An administrator has deployed NSX within the vSphere environment, but is unable to deploy an
NSX Controller. What step must be taken to resolve the issue?
A.
Register the third-party security service device or virtual appliance with NSX Manager
B.
Deploy a distributed router and enable the High Availability option.
C.
On the NSX Manager, select Enable multicast addressing and complete the configuration.
D.
Define a data security group for all deployed virtual machine groups.
C
I don’t believe any of these answers are correct. Why do I need to configure multicast to deploy a controller – it gets its IP addressing from an IP Pool.
Can be that the ESXI hosts are 5.1: You must specify a multicast address range for VMware ESX 5.1 hosts or when using the hybrid mode.
Not agree with any answer. I don’t need a mcast subnet to deploy a controller, actually I don’t need a host prepared to deploy a controller

“If an NSX controller is not deployed in your environment, you must add a multicast address range to spread traffic across your network and avoid overloading a single multicast address.”
Great!! Michael and the student are right – they assume to have an ESXi5.1 host.
I think that’s hard to remember in a test without getting full insight.
