Which database is responsible for storing the running configuration or installed software for devices?

The database responsible for storing the running configuration or installed software for devices is ConfigDB. This database is essential as it contains all the operational settings and configurations applied to the network devices, including firewalls, switches, and routers. It allows administrators to view and manage the current configurations and troubleshoot issues effectively.

ConfigDB is structured to hold critical information that reflects the active state of the device, making it a crucial component of network management. By maintaining a detailed record of the configurations, it helps ensure that the devices operate with the correct settings that align with organizational policies and operational requirements.

In contrast, other databases serve different purposes: CMDB (Configuration Management Database) focuses on managing and maintaining information about the organization’s configuration items, SVNDB (Software Versioning Database) tracks software versioning information, and LogDB is used for storing logs generated by devices for monitoring and auditing purposes. Thus, ConfigDB is distinct in its primary role of holding real-time operational configurations.
