Which of these is an advantage of creating an in-band rather than an out-of-band management network?

Protection of management traffic is an advantage of out-of-band management, which isolates management plane communications from potentially compromised or congested production paths.

In-band management reuses the same physical links, switches, and routers already deployed for production traffic, so no additional dedicated management switches, routers, or cabling are required, directly lowering capital equipment expenditure compared to out-of-band.

Separate transport equipment is a characteristic of out-of-band networks, which require dedicated hardware - the opposite of what in-band provides.

Protection of production traffic is an advantage of out-of-band management because it prevents management storms or attacks from consuming production bandwidth.
