What is the default value for config-revision on core devices used in this environment?

• A. 0
• B. 1
• C. 1-0
• D. 0.0

Answer: (A)

The concept here is how the device’s configuration revision counter is initialized and tracked. On core devices in this environment, the config-revision counter starts at zero, representing the baseline configuration before any user changes are applied. When you make and commit changes, the revision increments (1, 2, …) to record subsequent versions. Values like 0.0 or a range such as 1-0 aren’t used for this integer-style revision tracking, and starting at 1 would imply changes already exist at boot, which isn’t the case. So the default is zero.
