Which network mode in VirtualBox can be used to emulate unplugging the Ethernet cable from the network?

Internal Network mode

Which network mode would be best if you wanted to run a server on a VM that could be fully accessible from your physical local area network?

Bridged Networking mode

What are the three options of promiscuous mode and what does each do?

Deny: This option is the default setting in VirtualBox. In "Deny" mode, the virtual network adapter of the virtual machine is not allowed to see traffic that is not intended for it. The virtual adapter only receives network packets specifically addressed to it, and it cannot capture or monitor traffic on the network.

Allow VMs: When "Allow VMs" mode is selected, the virtual network adapter in the virtual machine is granted the ability to see all network traffic on the physical network interface of the host machine. This includes traffic that is not specifically intended for the virtual machine. With this mode enabled, the virtual machine can monitor and capture network packets from other machines on the same network.

Allow All: The "Allow All" mode is similar to "Allow VMs" mode, but with a wider scope. In "Allow All" mode, all virtual network adapters across all virtual machines on the host have the ability to see all network traffic on the physical network interface. This includes traffic that is not intended for any of the virtual machines. With this mode enabled, any virtual machine on the host can capture and monitor network packets from all machines on the network.

What is Port Forwarding?

Port forwarding is a technique used in computer networking to redirect incoming network traffic from one IP address and port combination to another IP address and port. It is commonly used to allow external access to services or applications running on a private network or a specific machine behind a router or firewall.
