You are having trouble connecting to the Internet. You are not able to determine whether it is the modem or the configuration that is causing the problem. Which of the following should you do to determine whether the modem is working properly?
Explanation
Answer - D - To determine if the modem is working properly, click Query Modem in the Diagnostics tab of the Modem Properties dialog box.
Key Takeaway: When you click the Query Modem button, Windows will send a series of sample commands to the modem. After a minute or two, Windows will display a summary of the commands that have been issued and the results of those commands. You should look through the list of commands for any errors that may appear in the Response column. If errors do show up, it could be a hardware conflict, a damaged modem, or an invalid device driver.
