A.

B.
A stratum-2 server is directly linked (not over a network path) to a reliable source of UTC time
such as GPS, WWV, or CDMA transmissions
C.
Stratum-0 servers are used on the network; they are not directly connected to computers which
then operate as stratum-1 servers
D.
Stratum-1 time server is linked over a network path to a reliable source of UTC time such as
GPS, WWV, or CDMA transmissions
