1. What does an IP address represent?
A password
The identifier of a machine on a network, paired with a mask and a gateway

The mask delimits the local network; the gateway is the exit toward other networks, including the internet.
2. What is DNS for?
Speeding up the disk
Translating domain names (e.g. site.com) into IP addresses
Blocking viruses

DNS is the internet's phone book. DHCP, by contrast, automatically assigns IP addresses to devices.
3. Which device connects a local network to the internet and routes between networks?
The switch
The router (often built into the box)
The printer
The monitor
A switch connects devices within the LAN; a router connects networks together. A home box often combines both.
4. Which command tests whether a machine responds on the network?
format
ping
shutdown
copy
ping tests reachability; ipconfig shows the IP configuration; tracert follows the path. Diagnose from nearest to farthest.
5. How do you properly secure a network share?
Leave it open to everyone
Grant access by need (least privilege) and manage the permissions
Delete the network
