Your environment has two sites designated as Site A and Site B. Each site has its own vCenler Server instance
with NSX installed and configured in standalone mode. You are migrating the environment to Cross vCenter
and have already promoted Site A to the Primary role. What action must be taken before the NSX Manager at
Site B can be changed to Secondary?
A.
Migrate the Site B Controllers to Site A
B.
Convert the Site B Controllers to Universal Controllers
C.
Remove any logical switches from the Site B NSX Controller.
D.
Delete the Controllers at Site B
Should be D.
See the following statement in vmware configuration guide.
“When assigning the secondary role to a NSX Manager, the vCenter linked to it must not have any deployed NSX Controllers.”
