A technician checks the proposed subnet boundaries for 192.168.10.77/26: network 192.168.10.64 and broadcast 192.168.10.127. Select all statements that correctly verify these results.

A
The proposed network address, 192.168.10.64, has all host bits set to zero.
B
The proposed broadcast address, 192.168.10.127, has all host bits set to one.
C
The given address, 192.168.10.77, is strictly between the proposed network and broadcast addresses.
D
The broadcast address must be 192.168.10.128 because that is the start of the next block.
E
Because 192.168.10.77 is between the endpoints, it is the network address.

For 198.51.100.206/28, a technician proposes network 198.51.100.192 and broadcast 198.51.100.207. Select all statements that correctly check the proposal.

A
The proposed network address, 198.51.100.192, has all host bits set to zero.
B
The proposed broadcast address, 198.51.100.207, has all host bits set to one.
C
The input address, 198.51.100.206, lies within the proposed block.
D
The broadcast address must be 198.51.100.208 because that is the first address after the block.
E
The proposed network and broadcast addresses are both assignable host addresses in an ordinary subnet.
