What does the certified directory contain?

• A. Files certified by an authorized administrator as the default files for the switch.
• B. Non-certified files that are not used by the switch.
• C. User-generated backups of the running configuration.
• D. Firmware updates retrieved automatically.

Answer: (A)

The main idea is that the certified directory is a trusted repository of files that have been approved by an authorized administrator to be used as the default set for the switch. These files are considered safe, tested, and compatible with the device, so the system can rely on them as the baseline during boot or normal operation. Having them labeled as certified helps ensure stability and supportability, since unverified or experimental files won't be used as the default. The other options describe files that aren’t intended to be the default trusted set—non-certified files aren’t used as defaults, backups belong in a different area, and firmware updates are handled separately from the default file set in the certified directory.
