Connects to a separate and isolated network not accessible from the internet or the rest of the LAN.

• A. VLAN
• B. Audit Log
• C. Precise Methods
• D. Out of band (OOB)

Answer: (D)

Out-of-band management means using a separate, dedicated network path for administering devices. This network is isolated from the regular LAN and is usually not reachable from the internet. The idea is to keep management traffic on its own wires or its own subnet, often accessed through a console server, a dedicated management switch, or separated NICs, with strict access controls. This keeps you able to manage servers and network gear even if the main production network is down or compromised, and it protects the management plane from exposure on the public network. A VLAN, while helpful for segmenting traffic within the LAN, still sits on the same broader network and can be routed to the internet if allowed, so it doesn’t inherently provide the same level of isolation as an out-of-band management network. Audit logs are records of events, not networks, and the term in question isn’t about a logging mechanism. The option that describes a separate, isolated management path best matches the scenario.
