Which feature allows a dynamic PAT pool to select the next address in the PAT pool instead of the next port of
an existing address?

A.

B.
round robin

C.
dynamic rotation

D.
NAT address rotation

Explanation:
BD
The round-robin keyword enables round-robin address allocation for a PAT pool. Without round robin, by
default all ports for a PAT address will be allocated before the next PAT address is used. The round-robin
method assigns an address/port from each PAT address in the pool before returning to use the first address
again, and then the second address, and so on.
