A network architect needs secure access to the organization's perimeter routers and firewalls. The administrator must access network devices from a remote location that is reachable from the WAN cloud

Creating a secure IPsec tunnel using an internet link is a method for secure communication, but it still relies on the in-band production internet link for management, making it vulnerable if the production network or the internet link itself becomes unavailable or compromised.

Enabling SSH with a strong username and password using an internet link secures the management session, but it remains an in-band management approach, which is less resilient to production network failures or DDoS attacks compared to a dedicated out-of-band network.

Creating an in-band network management network uses the same network infrastructure as user and data traffic, which compromises security and availability for management access if the production network experiences issues or attacks.
