What is a limitation to using OOB management on a large enterprise network?

• All devices appear to be attached to a single management network.
• OOB management requires the creation of VPNs.
• Production traffic shares the network with management traffic.
• Terminal servers can have direct console connections to user devices needing management.
  

  Answers Explanation & Hints: OOB management provides a dedicated management network without production traffic. Devices within that network, such as terminal servers, have direct console access for management purposes. Because in-band management runs over the production network, secure tunnels or VPNs may be needed. Failures on the production network may not be communicated to the OOB network administrator because the OOB management network may not be affected.​
