A network administrator must choose a method to manage network devices in a critical data center with high security and uptime requirements. The selection should minimize the risk of network congestion impacting management accessibility. Which option is the most appropriate for this scenario?
You selected this option
Use out-of-band management via a dedicated management network.
You selected this option
Only perform physical access management on-site.
You selected this option
Manage devices over the primary data network for simplicity.
You selected this option
Use a virtual private network (VPN) for device management.
Out-of-band management is ideal for scenarios requiring high security and reliability like critical data centers because it uses a dedicated management channel that does not compete with regular network traffic. This reduces the risk of management access issues during high traffic load on the primary network. In-band management, while practical for using the same network paths as data traffic, could face accessibility issues during network congestion. Using a VPN or relying solely on physical access does not address the risk of network congestion impacting device management.
