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?
