You are the administrator for a large company that has purchased a new multifunction printer. You want to publish the printer to Active Directory. Where is one possible place would you click in order to accomplish this task?

You are the administrator for a large company that has purchased a new multifunction printer. You want to publish the printer to Active Directory. Where is one possible place would you click in order to accomplish this task?

• The Printing Preferences button
• The Advanced Tab
• The Device Settings Tab
• The Sharing Tab 

EXPLANATION

You will need to go to the Sharing Tab and then checkmark "List in directory" and then hit apply. This will then publish it to the AD.

You need to publish shares in the directory before they are available to the users of the directory. If NetBIOS is still enabled on the network, the shares will be visible to the NetBIOS tools and clients, but you do not have to enable NetBIOS on shares. Although replication must occur before the shares are available in the directory, it is unlikely that the replication will not have occurred by the next day. If this is the case, then you have other problems with the directory as well.

What is the standard command for a modem to answer?

What is the standard command for a modem to answer?

• AT DT
• AT A
• A/
• AT Z 

 

EXPLANATION

Modem Command strings are prefixed with "AT" to get the modem's "attention".  A is the code for "Answer".  This typically requires no Carriage Return to follow, as that is interpreted by the
modem as a cancellation.  AT Z resets the modem, AT DT Dials touch tone (usually the default dialing method), and A/ repeats the last command.
