A network administrator is allocated the subnet of 10.100.32.0/19 for use at a corporate site. What subnet mask can the administrator use to variably subnet the subnet into 64 new subnets?

255.255.254.0
255.255.255.128
255.255.255.0
255.255.248.0

Explanation: Creating 64 subnets requires six bits. If the subnet mask is moved six bits to the right, the new subnet mask becomes 255.255.255.128.
