Which of the following IP addresses could be teased as a result of the new configuration if you are tasked to configure the DHCP server to lease the last 100 usable IP addresses in the subnet. 10.1.4.0/23?

The IP address that could be leased as a result of the new configuration is 10.1.5.200.

The subnet mask /23 means that the first two octets of the IP address are the network ID, and the last two octets are the host ID. The subnet ID for 10.1.4.0/23 is 10.1.4.0, and the broadcast address is 10.1.5.255. This means that there are 254 usable IP addresses in the subnet, starting from 10.1.4.1 and ending in 10.1.5.254.

If the DHCP server is configured to lease the last 100 usable IP addresses, then the IP addresses that could be leased are 10.1.5.155 to 10.1.5.254. The IP address 10.1.5.200 is within this range, so it could be leased.

The other IP addresses listed are not within the range of the last 100 usable IP addresses. The IP address 10.1.4.254 is the broadcast address, and the IP address 10.1.4.156 is not a valid IP address in the subnet 10.1.4.0/23. The IP address 210.1.55.200 is not in the same subnet as 10.1.4.0/23, so it could not be leased by the DHCP server.
