To deploy 512 desktops for remote workers, the subnet chosen must provide at least 512 usable IP addresses. A /22 subnet provides 1024 total IP addresses, of which 1022 are usable because 2 IP addresses are reserved (one for the network address and one for the broadcast address). Hence, a /22 subnet would meet the minimum requirement for 512 IP addresses, ensuring there are enough usable addresses for the desktops.
A. You all got the answer right, but you explanations are still off. Reserving 2 addresses (broadcast) is for classic physical networking. Cloud subnetting steals even more from the usable pool of IPs. Both AWS and Azure steal 3 more usable IPs for their own mumbo-jumbo. So if the question required 510 or even 509 IPs, you'd still need a /22 for the main public clouds.
In a subnet, the first address (lowest) and last address (highest) are typically reserved for special purposes: The first address is reserved for the Network ID. The last address is reserved for the Broadcast Address. So, while a /23 subnet can theoretically provide 512 host addresses, you should account for these reserved addresses. In practical terms, a /23 subnet will provide 510 usable host addresses for devices like desktops.
There are only 510 hosts spots on /23 so it has to be /22
/24 256 -2 254 /23 512 -2 510 /22 1024 -2 1022
answer should be A. /23 gives us 512 IPs, but two of those are reserved for Network Address and Broadcast address thus only leaving 510 IPs for the hosts. /22 gives us 1024 IPs (1022 useable)
Answer is A A /23 network has 512 total addresses but only 510 usable addresses, you must account for the 2 addresses that cannot be used for hosts which are the network address and broadcast address. A /22 (255.255.252.0) network has 1024 address with 1022 IP addresses usable for hosts.
/22 subnet: This provides 1024 IP addresses (2^(32-22) = 1024). Since 512 desktops are required, a /22 subnet will have enough addresses to cover this requirement and have additional addresses available for other purposes.
