26. c. show interfaces
- show interfaces displays configurable parameters and statistics for all interfaces.

27. c. Setup mode
- With NVRAM cleared (no startup-config) the switch boots into the initial setup dialog (setup mode).

28. d. Part of the command is missing.
- The correct form is "show interfaces FastEthernet0/1" (or "show interface FastEthernet0/1"); "show fastethernet 0/1" is not a valid show command.

29. b. There is more than one show command that starts with the letter r.
- "sh r" is ambiguous (e.g., show running-config and other show commands beginning with r), so IOS requests a less ambiguous input.

30. b and d. show interfaces; show ip interface
- show interfaces shows layer 1/2 status and interface IP info; show ip interface shows IP addressing and IP-related interface status.
