Ch 9 TEST Q/A

 

What steps must occur for devices to communicate between different physical network segments? (Choose two.)

 

learning the IP address of the source device

 

obtaining the MAC address of the intermediate device

It allows user to be mobile.

What should a system administrator consider when assigning an IP address to a network server? (Choose two.)

 

 

Servers should have addresses assigned dynamically through a DHCP.

 

 

Servers with a dynamically assigned IP address would be difficult to locate on a network.
