Mastery Unit 1

Which core network component is responsible for connecting two or more different networks (e.g., a home network to the internet)?

• Switch

• Modem

• Router

• Server

The primary function of a Modem is to:

• Forward data within a local network using MAC addresses.

• Convert digital signals to analog and vice-versa.

• Store and manage shared files for clients.

• Assign IP addresses automatically.

A Switch operates at which layer of the OSI model and uses what type of address for forwarding?

• Layer 3 (Network); IP Address

• Layer 1 (Physical); IP Address

• Layer 2 (Data Link); MAC Address

• Layer 4 (Transport); Port Number

Which network component is a host that provides centralized resources and services, such as file storage or email, to client devices?

• Router

• Switch

• Modem

• Server

What is the main advantage of a Wired Ethernet connection over Wi-Fi?

• Greater mobility

• Easier installation

• Higher, more consistent speed and lower latency

• No physical cables required

Which wireless technology is primarily used for creating a Personal Area Network (PAN) for short-range device pairing?

• Wi-Fi (802.11)

• Bluetooth

• Cellular 4G/5G

• Fiber Optic

In a Star topology, what device is located at the center and acts as the central connection point?

• Router

• Modem

• Server

• Switch or Hub

The key characteristic of a Bus network topology is:

• Devices are connected in a closed loop.

• Every device is connected directly to every other device.

• All devices share a single communication backbone cable.

• All communication flows through a central switch.

Which topology offers the highest redundancy and fault tolerance due to multiple paths between nodes?

• Star

• Bus

• Ring

• Mesh (Full or Partial)

What is the single point of failure in a Star topology?

• Any individual cable connecting a device.

• The central switch or hub.

• The backbone cable.

• The terminators.
