Refer to the exhibit. An architect is designing an IPv4 plan using the 172.16.0.0/16. The design must maximize the number of subnets while meeting these requirements:
• 500 hosts within the server room
• 100 hosts at the remote site
• 25 hosts at the access site
Which plan must the architect choose?
How about 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
A-incorrect, remote and access overlap B-correct, maximizes subnets available without overlap and provides each site enough hosts C-incorrect, not enough hosts at remote site D-incorrect, remote and access sites overlap
B is the only one that makes sense -> 23 -> 512, 25 ->128 and 27 ->32
