Refer to the exhibit. An engineer is creating a new TACACS+ command set and cannot use any show commands after logging into the device with this command set authorization. Which configuration is…

Question marks can be used as wildcards in some contexts, but TACACS+ command sets often rely on regular expressions where the syntax for wildcards is more specific, such as `.` for any single character or `.*` for any sequence of characters.

If the command set were allowing all commands not in the list, the user would be able to execute 'show' commands, which contradicts the problem statement that they cannot use them.

TACACS+ command sets often utilize regular expressions for defining command permissions. If the intended wildcard for 'show' commands (e.g., `^show.*`) is syntactically incorrect or uses an unsupported wildcard character, the commands will not match any `permit` rule and will therefore be implicitly denied. This results in the user being unable to execute 'show' commands.

While TACACS+ command sets function like ACLs, denying 'every command' would prevent any action, potentially even login, which is not the specific issue described; the user can log in but cannot use 'show' commands.
