Routing is important even in virtual environments. Just as VMs enable IT professionals to conserve resources, VLANS work the same way, and they're very useful.
Which network mode in VirtualBox can be used to emulate unplugging the Ethernet cable from the network?
Not attached
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 adapter
What are the three options of promiscuous mode and what does each do?
Deny: Any traffic that is not intended to the virtual network adapter of the VM is hidden from the VM. This option is set by default
Allow VMs: All traffic is hidden from the VM network adapter except the traffic transmitted to and from other VMs
Allow All: There are no restrictions in this mode. A VM network adapter can see all incoming and outgoing traffic.
What is Port Forwarding?
Port forwarding is a process of intercepting traffic addressed to the appropriate IP address and port in addition to redirecting that traffic to a different IP address and/or port, and one of the most popular use cases for port forwarding is by providing access to particular network services that are hidden behind the NAT from external networks.
Things I want to know more about
I would definitely like to get more practice working with VLANs.
