Which statement describes a difference between the Cisco ASA IOS CLI feature and the router IOS CLI feature?

• ASA uses the ? command whereas a router uses the help command to receive help on a brief description and the syntax of a command.
• To use a show command in a general configuration mode, ASA can use the command directly whereas a router will need to enter the do command before issuing the show command.
• To complete a partially typed command, ASA uses the Ctrl+Tab key combination whereas a router uses the Tab key.
• To indicate the CLI EXEC mode, ASA uses the % symbol whereas a router uses the # symbol.

Explanation: The ASA CLI is a proprietary OS which has a similar look and feel to the Cisco router IOS. Although it shares some common features with the router IOS, it has its unique features. For example, an ASA CLI command can be executed regardless of the current configuration mode prompt. The IOS do command is not required or recognized. Both the ASA CLI and the router CLI use the # symbol to indicate the EXEC mode. Both CLIs use the Tab key to complete a partially typed command. Different from the router IOS, the ASA provides a help command that provides a brief command description and syntax for certain commands.
