A storage administrator has just configured a newly acquired Isilon cluster. The
administrator connected to the console port of Node 1 and created subnets, pools, and two
access zones called “Blue” and “Green”. The administrator then created shares in zone
“Blue” and is able to access the shares from their Microsoft Windows clients. In addition, the
administrator created exports in the “Green” zone and is able to access the exports from
their UNIX clients. However, the administrator is unable to SSH into the cluster and login as
root. What is a possible cause for this issue?

A.
No interfaces exist in the System zone

B.
No authentication providers are defined in the “Blue” and “Green” access zones

C.
No failover address was configured for the InfiniBand network

D.
A local user “root” needs to be created
