220-1102 Question 124
Single answer[command name] /?A support technician is connected to a Windows 10 user's PC through a remote session. The user says they were instructed to use a built-in command, but they do not remember the exact syntax or available switches. The technician wants the fastest built-in way to display the command's usage information directly in Command Prompt before advising the user. Which action should the technician take?
- A
Run the command followed by /? to display the command's help and syntax
- B
Run help /? to force Windows to list every switch for the specific command
- C
Open Task Manager and review the command's properties for usage details
- D
Run the command followed by /help because all Command Prompt commands use that switch
Show answer and explanation
Correct answer: A
Explanation
For A+ Core 2, candidates should recognize practical command-line troubleshooting methods used in Windows. In Command Prompt, entering a command followed by /? commonly displays that command's built-in syntax and usage information. This is especially useful when a technician remembers the command name but not the exact switches. Microsoft documentation for many CMD utilities presents syntax help in this format, and it is a standard best practice for quick verification before making system changes. While the help command can also be useful, command /? is the most direct and broadly applicable method when checking a specific command's usage from the prompt.
- A. Correct.
Correct. In Windows Command Prompt, many built-in commands support the syntax command /? to display usage information, available switches, and examples directly in the console. This is the quickest built-in way to check a command's syntax during troubleshooting.
- B. Incorrect.
Incorrect. The help command can list help for some commands, but help /? does not target a specific command in the way described. To get help for a particular command, a technician would typically use either help
or /?, depending on the command. This option misstates how the help utility is used. - C. Incorrect.
Incorrect. Task Manager is used to monitor processes, performance, startup items, and services. It does not provide syntax help or switch documentation for Command Prompt commands. A candidate might pick this if they confuse process details with command-line documentation.
- D. Incorrect.
Incorrect. /help is not a universal switch for Windows Command Prompt commands. Some utilities may support alternative help formats, but the standard and widely expected method in CMD is /?. Assuming /help works for all commands is a common misconception.
