A+ virtual machine networking: NAT, bridged and host-only
Choose a VM network mode from the desired boundary. NAT commonly gives a guest outbound access through the host. Bridged networking puts the guest onto the physical network as a separate participant. Host-only networking supports a private host-and-guest lab. Names and exact defaults vary by product, so verify the virtual network configuration rather than relying only on the mode label.
How to read the scenario
For risky lab work, verify actual isolation and sharing settings. A snapshot helps rollback but does not replace a separate backup.
Identify the required outcome, the evidence already provided, and the limits on the technician’s action. Compare every option against those details before deciding. Record why the closest alternative does not meet the stated need.
Original practice example
A server virtualization layer runs directly on the hardware instead of inside a general-purpose host operating system. What is it?
- Virtual machine snapshot
- Container
- Type 1 hypervisor
- Type 2 hypervisor
Show the answer and explanation
Type 1 hypervisor
A Type 1 hypervisor runs directly on the hardware to host virtual machines.
