10.0.0.0/24 Subnet Broadcast Message

Answer - D.

This is given in the AWS Documentation that VPC's don't support broadcast or multicast.

For more information on VPC's, please refer to below URL:

In AWS, broadcasts are not allowed between subnets. This is because AWS operates in a virtualized environment and its network architecture is designed to prevent broadcast storms that can result in network congestion and performance degradation.

However, for the sake of the question, let's assume that you want to send a broadcast message to your 10.0.0.0/24 subnet using the traditional method.

In IPv4, a broadcast address is a special address that is used to send a message to all hosts on a specific network. The broadcast address is usually the highest address in the subnet range, and it is represented by setting all host bits to 1.

For example, if you have a subnet with the network address 10.0.0.0/24, the broadcast address would be 10.0.0.255. This is because the subnet mask for this network is 255.255.255.0, which means that the first 24 bits are reserved for the network address, and the last 8 bits are available for host addresses.

So, the correct answer to the question would be A. 10.0.0.255, assuming that you are using the traditional method of sending broadcast messages. However, as mentioned earlier, broadcasts are not allowed in AWS, and you should use other methods, such as multicast or unicast, to communicate between subnets.
