Answer :
Final answer:
The network layer is responsible for routing data packets from the source to the destination across different networks. The IP addresses that exist in the subnet 10.1.1.0/24 are 10.1.1.10 and 10.1.1.128.
Explanation:
The network layer is responsible for routing data packets from the source to the destination across different networks. It provides logical addressing and routing functions. The given scenarios can be matched to the network layer as follows:
- Converting a digital signal to an electromagnetic waveform: Physical layer
- Broadcasting a request for an address on a local network: Network layer
- Routing to a location across the world: Network layer
- Creating a data session between two computers: Transport layer
- Downloading and consuming data from a website: Application layer
To determine the IP addresses that exist in the subnet 10.1.1.0/24, we need to consider the range of IP addresses within the subnet. The subnet 10.1.1.0/24 has a subnet mask of 255.255.255.0, which means the first three octets (10.1.1) are fixed, and the last octet can range from 0 to 255.
The IP addresses that exist in the subnet 10.1.1.0/24 are:
- 10.1.1.10
- 10.1.1.128
