The followings about LAN setup are true EXCEPT:

• IP address of 192.61.3.1, 192.61.3.2 and 192.61.3.4 in a network is likely belongs to the same LAN

• The switch will have a table that keep track the MAC address of devices and its IP address.

• External ISP modem will be directly connected with a Switch in order for the system to works.

• Using DHCP, devices that join the LAN will be automatically given an IP address.

What is DHCP?

Answer explanation

DHCP (Dynamic Host Configuration

Server) server automatically allocates addresses to all

the devices connected to the network.

What is TLD?

Answer explanation

Top-level domain (TLD): This is the last part of the domain name, following the dot (e.g., .com, .org, .net, .edu). TLDs can indicate the type of organization or the geographical location associated with the domain. For example, in "example.com," ".com" is the top-level domain.

• Network devices: router, switch, modem (if not already present in the

router)

• Sharing resources: printers, disk drives, etc.

• Cables: Ethernet cables, wires for connecting other devices (in case of

wired LAN)

• Internet connection: Wi-Fi (in case of wireless LAN)

What is the difference between Switch, Router and Hub?

Answer explanation

Switch is a device for LAN that connects devices into one single network. In the network communications between one device and another device is private.

Hub is a device for LAN that connects devices into one single network. In the network communications between one device and another device is public.

Router is a device that connects multiple LAN (network). It enables the separation of different network (LAN) while allowing inter network communication whenever needed.
