What should be done with router configuration files?

• A. Publish router configurations publicly.
• B. Secure and synchronize router configuration files.
• C. Delete router configs after setup.
• D. Ignore router configuration management.

Answer: (B)

The main idea is that router configuration files must be protected and kept in sync to prevent sensitive information from leaking and to ensure devices can be recovered and kept consistent. These files often contain passwords, SNMP strings, interface settings, and access controls. Keeping them secure—through access controls, encryption at rest, and restricted distribution—reduces the risk of unauthorized access or exposure. Synchronizing configurations through a centralized process or repository ensures all devices share a known-good baseline, making it easier to apply approved changes, audit what’s been deployed, and recover quickly if a device fails or is compromised. Publishing them publicly would reveal credentials and network details, while deleting them after setup would leave you unable to restore or reconfigure devices, and ignoring configuration management invites drift and misconfigurations.
