when synchronizing a PC with a PDA that is in line of sight


38. 
    Refer to the exhibit. What is a possible reason that the PC is unable to ping the default gateway IP address? 
A straight-through cable should be used to connect the PC to the switch


39. What is a weakness of WEP that is solved by WPA? 
WEP uses the same key for every connection whereas WPA uses a different key for each connection.


40. How does a crossover cable connect two routers?
