Networking Questions

Which of the following is true about a Local Area Network (LAN)?

• It typically spans across galaxies, connecting Jedi and Sith alike.

• It connects devices within a single building or campus, so you can finally send memes to the person in the next room.

• It uses satellite communication to ensure that your internet drops out exactly when you're about to win an online game.

• It is used to connect mobile devices over large distances, mostly to track down your lost phone.

What does DHCP do?

• It decides which Wi-Fi signal you can ignore because it's not yours.

• It dynamically assigns IP addresses to devices, so you don't have to argue with your laptop about who gets which address.

• It orders pizza when you type 'food' in your browser.

• It translates internet traffic into Morse code, for no reason at all.

Which of the following is a characteristic of a peer-to-peer (P2P) network?

• A central server manages all network resources while drinking coffee and complaining about load.

• All devices on the network can share resources equally, like a potluck where everyone brings chips.

• It requires high-level network administration, usually involving a wizard with a staff.

• It is more secure than client-server networks because nobody has anything worth stealing.

Which device allows multiple network segments to communicate with each other while filtering traffic based on IP addresses?

• Hub, because it's too cool to care about filtering anything.

• Switch, it likes to switch things up-literally.

• Router, the traffic cop of your network, minus the flashy lights.

• Repeater, which only repeats what you say, like an annoying sibling.

Which of the following network devices amplifies the signal to extend the range of a network?

• Router, though it prefers being the boss over amplifying things.

• Switch, because switching things up can only get you so far.

• Repeater, the one that shouts your Wi-Fi signal across the room.

• Bridge, which is good for crossing troubled waters, but not amplifying signals.

Which device in a network is responsible for connecting to the Internet and often provides routing and firewall functions?

• Switch, who's really good at switching but not so much at multitasking.

• Hub, which is great at spreading rumors (data), not so much at securing anything.

• Router, the Internet's gatekeeper, just without the fancy robe.

• Access Point, which is like a Wi-Fi butler that only handles local connections.

Which protocol is responsible for ensuring data is transmitted reliably between two devices on a network?

• TCP, the protocol that's like your reliable best friend, always double-checking everything.

• UDP, who's more of a 'send and forget' kind of friend.

• HTTP, which only cares about showing you cat videos.

• FTP, who's still figuring out how to transfer that one big file from last year.

Which command can be used to display the IP address, subnet mask, and default gateway for a device?

• netstat, which is really good at statting, not much else.

• ipconfig, the network's detective, always finding your IP details.

• ping, which just wants to check if you're still there.

• tracert, which prefers long walks through the network to short diagnostics.

What is the primary use of the `traceroute` command in networking?

• To find the IP address of a domain, though it's more like a treasure hunt.

• To display the routing path and measure the delay of packets across a network, because who doesn't love knowing where their data has been?

• To check if a specific host is reachable, like sending out a digital carrier pigeon.

• To display all active network connections, because being nosey is a thing.

Which command would you use to test connectivity between your computer and another device on the network?

• nslookup, which is more interested in finding names than testing connections.

• ping, the digital version of 'You there?'

• netstat, because counting connections is what it does best.

• ipconfig, which just wants to tell you about your own device.
