Exam E20-559: Isilon Solutions Specialist Exam for Storage Administrators

how many addresses need to be put into the pool to ensure an even number of IP addresses per node after failov

A company has an Isilon cluster on which they want to configure dynamic pools. The cluster
consists of 5 nodes. The pool will consist of one 1Gbps Ethernet external interface on each
of the nodes. Because the address space is limited at the company’s site, they will need to
implement dynamic pools using a minimum number of addresses. If the company puts all
interfaces in one pool and sets it to dynamic with round robin failover, how many addresses
need to be put into the pool to ensure an even number of IP addresses per node after
failover distribution should a node fail?

What is a possible cause for this issue?

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?
