Private addresses are network or host addresses that are constrained for use within internal networks...

Private IPv4 addresses are defined in RFC 1918 and are intended for internal networks rather than direct public Internet routing.

The HCIA-Datacom V2.0 Training Material identifies three private IPv4 address ranges: 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16.

Option A, 192.168.1.1, belongs to the 192.168.0.0/16 private range.

Option C, 192.168.255.254, also belongs to this range.

Option D, 10.0.12.1, belongs to the 10.0.0.0/8 private range.

However, option B, 172.32.32.32, falls outside the private 172.16.0.0 through 172.31.255.255 range.

The address 172.32.32.32 is therefore not part of the RFC 1918 private address space.

Consequently, the correct answer is B.
