A network engineering team implements an automated, controller-led management model to enforce baseline configurations across 200 edge routers. Instead of manually pushing changes via device-by-device CLI scripts, the team defines target configurations in centralized declarative state files. Which operational benefit is primarily realized by adopting this automated approach?
- Device configurations are continuously aligned with a centralized intent model, reducing configuration drift and operational errors.Answer
- BEvery managed router must run a local software agent to translate incoming SSH commands into hardware execution flows.
- CConfiguration updates utilize periodic HTTP GET requests to directly modify and overwrite device startup settings.
- DCentralized controller management removes the requirement for an underlying IP transport network between managed routers.
Answer
Device configurations are continuously aligned with a centralized intent model, reducing configuration drift and operational errors.
Automated network management leveraging declarative state models ensures that network devices match a predefined single source of truth. The controller or automation engine automatically reconciles discrepancies, which eliminates configuration drift, reduces manual intervention, and lowers the risk of human error during large-scale network changes.
