The local or the remote?

What two network configuration parameters are required to communicate to another device on the local subnet?

A) Default gateway

B) IP address

C) Subnet mask

D) DNS server

E) A megaphone

The answers: B) IP address and C) Subnet mask

At a bare minimum, you must have an IP address and a subnet mask to communicate via TCP/IP. To talk with devices outside of your local subnet, you’ll need a default gateway. If you need to reference remote devices by name, then you’ll also need to configure a DNS server address.
