10. You are a'solutions architect who works at a large retail company that is migrating its existing infrastructure to AWS. You recommend that they use a custom VPC you create a VPC , you assign it to an IPv4 Classless Inter -Domain Routing (CIDR block of 10.0.1.0/24 (which has 256 total IP addresses). How many IP addresses are available? (Select the best answer.) 250 251 246 256

When you create a VPC with a CIDR block of \(10.0.1.0/24\), it indeed has 256 total IP addresses (from \(10.0.1.0\) to \(10.0.1.255\)). However, AWS reserves some IP addresses in each subnet for its own use:<br /><br />1. The first IP address in the subnet is reserved for the network address.<br />2. The second IP address is reserved for the VPC router.<br />3. The third IP address is reserved for future use.<br />4. The last IP address is reserved for the broadcast address.<br /><br />Therefore, out of the 256 IP addresses, 5 are reserved by AWS, leaving 251 IP addresses available for use.<br /><br />The best answer is: **251**.
