For what purpose would computer 1 send a FF:FF:FF:FF:FF broadcast ARP message to all nodes on network A? To obtain Router Y's MAC address To obtain Computer 2 MAC address To calculate the TTL To verify the internet connection

Computer 1 would send a FF:FF:FF:FF:FF broadcast ARP (Address Resolution Protocol) message to all nodes on network A to obtain the MAC (Media Access Control) address of a specific device on the same network.

In this case, the purposes could be:

1. To obtain Router Y's MAC address: If Computer 1 wants to send data to Router Y, it needs to know the MAC address of Router Y. If it doesn't have this information, it will send a broadcast ARP request to all devices on the network. The device with the IP address that matches Router Y will respond with its MAC address.

2. To obtain Computer 2's MAC address: Similarly, if Computer 1 wants to communicate with Computer 2, it needs to know Computer 2's MAC address. It will send a broadcast ARP request to obtain this information.

The other options are not typically reasons for sending a broadcast ARP message:

3. To calculate the TTL (Time To Live): TTL is a mechanism used to avoid endless network loops, limiting the lifespan or lifetime of data in a computer or network. It doesn't require the MAC address of a device, so a broadcast ARP message wouldn't be used for this purpose.

4. To verify the internet connection: While ARP is used to resolve network layer addresses into link layer addresses, it's not typically used to verify an internet connection. Other protocols and methods are used for this purpose.
