Which two hosts exist on the same subnet? (Choose two.)
- host 172.16.101.199/23
- host 172.16.98.250/23
- host 172.16.100.4/23
- host 172.16.97.78/23
- host 172.16.102.237/23
Explanation: Hosts 172.16.100.4/23 and 172.16.101.199/23 both exist in network 172.16.100.0/23. This network includes all addresses from 172.16.100.1 through 172.16.101.255.

sorry chat gpt made the mistake of calculation 1 AND 1 to 0 . stupid AI here is his answer LOOL
Certainly! Let’s perform the logical AND operation between the IP addresses and the subnet mask to determine the network address:
IP address 172.16.97.78:
- Binary representation: 10101100.00010000.01100001.01001110
Subnet mask 255.255.254.0:
- Binary representation: 11111111.11111111.11111110.00000000
Performing the logical AND operation:
10101100.00010000.01100001.01001110 (IP address)11111111.11111111.11111110.00000000 (Subnet mask)10101100.00010000.01100000.00000000
The result of the logical AND operation is:
Network address: 172.16.96.0
For the IP address 172.16.97.78, the network address is 172.16.96.0.
Performing the same operation for the second IP address:
IP address 172.16.98.250:
- Binary representation: 10101100.00010000.01100010.11111010
Subnet mask 255.255.254.0:
- Binary representation: 11111111.11111111.11111110.00000000
Performing the logical AND operation:
10101100.00010000.01100010.11111010 (IP address)11111111.11111111.11111110.00000000 (Subnet mask)10101100.00010000.01100000.00000000
The result of the logical AND operation is:
Network address: 172.16.96.0
For the IP address 172.16.98.250, the network address is also 172.16.96.0.
As both IP addresses have the same network address, it confirms that they belong to the same subnet.
