During an architecture review, you discover the organization has no out-of-band management network for network devices. Why is an out-of-band management network considered a key element of defensible architecture?
Select an answer to reveal the explanation.
Short Explanation
You need an out-of-band management network because it gives you a separate, dedicated path to manage devices even when the production network is down, congested, or compromised. That keeps you in control during an incident.
Full Explanation
The correct answer is the dedicated management path because an out-of-band management network allows administrators to access and reconfigure devices during an incident even if the in-band production network is down, congested, or compromised. The topology-scanning claim is wrong because topology obscurement is a separate concern unrelated to out-of-band management. The cost-reduction claim is wrong because cost reduction is not the primary security driver. The encrypted-protocol claim is wrong because out-of-band management does not eliminate the need for encrypted protocols such as SSH.
