4.2 Given a troubleshooting scenario involving a small office/home office network failure (e.g., xDSL, cable, home satellite, wireless, POTS), identify the cause of the failure.

Your WAN connection will often be handled by an ISP and out of your direct control. Make sure it is a WAN connection problem first though—all network segments will be affected if so. Phone support may be the next move here.

LAN troubleshooting involves several points:

 

PING order:

PINGing by both IP address and domain name can also test your DNS.

 

4.3 Given a troubleshooting scenario involving a remote connectivity problem (e.g., authentication failure, protocol configuration, physical connectivity) identify the cause of the problem.

Just when you thought it was safe to send your users off site . . . troubleshooting remote connectivity is no different from troubleshooting a problem onsite. You'll still need to determine the symptoms and how many users or portions of your wider network are affected. That in hand, determining the cause should be a simple deductive matter. Things to check will still include physical connections (yes, even in a remote situation, this will be the most common cause of your problem), network configuration setting on the remote station, any new software that's been added, difficulties on the receiving end (is the RRAS server up?), and the user's rights.

 

4.4 Given specific parameters, configure a client to connect to the following servers:
