出題：6

Your flex cluster has these attributes:
1. Hub nodes host01 and host02
2. Leaf nodes host03 and host04
3. Full Featured GNS is configured and running.
You attempt to run this command to add two more nodes to the cluster:
$ ./addnode.sh -silent "CLUSTER_NEW_NODES={host05,host06}"
"CLUSTER_NEW_NODE_ROLES={hub,leaf}"
What is the result and the reason for this result?

A. It succeeds because no VIP specification is required for leaf nodes and none need to be specified for hub nodes when using full featured GNS.

B. It fails because GNS doesn't assign VIPs for leaf nodes and no VIP was specified in the command.

C. It fails because no VIP was specified for the hub node host05.

D. It fails because hub and leaf nodes may not be added by the same execution of addNode.sh.
