An enterprise moves away from manual configuration methods, making changes by editing centralized configuration files. Which answers list an issue solved by using a version control system with those centralized files? (Choose two answers.)
- The ability to find which engineer changed the central configuration file on a date/time
- The ability to find the details of what changed in the configuration file over time
- The ability to use a template with per-device variables to create configurations
- The ability to recognize configuration drift in a device and notify the staff
Explanation: The version control system, applied to the centralized text files that contain the device configurations, automatically tracks changes. That means the system can see which user edited the file, when, and exactly what change was made, with the ability to make comparisons between different versions of the files.
The two incorrect answers list very useful features of a configuration management tool, but those answers list features typically found in the configuration management tool itself rather than in the version control tool.
