Selected Answer: B

Option B: Server room: 172.16.2.0/23 (provides 512 IPs — good for 500 hosts). Remote site: 172.16.4.128/25 (provides 128 IPs — good for 100 hosts). Access site: 172.16.5.32/27 (provides 32 IPs — good for 25 hosts). This option meets all the requirements and is very efficient in terms of IP address allocation
