What is the primary function of a Layer 2 Switch in networking devices?

• To connect multiple networks and provide dynamic routing

• To connect either an end device or another intermediary device using MAC addresses

• To encrypt and secure network traffic

• To assign IP addresses to devices on the network

Answer explanation

A Layer 2 Switch connects devices using MAC addresses, making forwarding decisions based on the data link layer, not IP addresses.

Which type of switch is also known as a Multilayer Switch?

• Layer 1 Switch

• Layer 2 Switch

• Layer 3 Switch

• Layer 4 Switch

Answer explanation

Layer 3 Switch is also known as a Multilayer Switch, as it operates at the network layer and can perform routing functions like a router.

What additional capability does a Layer 3 Switch have compared to a Layer 2 Switch?

• It can only communicate using MAC addresses

• It can encrypt data packets

• It can communicate within its own local network and/or remote networks if used as a router

• It can only operate within a single network

Answer explanation

A Layer 3 Switch can communicate within its own local network and/or remote networks if used as a router, unlike a Layer 2 Switch which can only operate within a single network.

What is the primary function of a router in networking?

• To connect end devices and network devices without making forwarding decisions

• To serve as an intermediary device capable of communication with remote networks using IP addresses

• To increase the signal strength of network communications

• To manage the power supply to network devices

Answer explanation

To serve as an intermediary device capable of communication with remote networks using IP addresses

Which layer of the OSI model does a hub operate at?

• Layer 3

• Layer 7

• Layer 1

• Layer 2

Answer explanation

A hub operates at Layer 1 of the OSI model, which is the physical layer responsible for transmitting raw data bits over a physical medium.

What is a hub NOT capable of doing?

• Connecting end devices and network devices

• Making forwarding decisions

• Repeating signals to extend the reach of a network

• Filtering or transforming data traffic

Answer explanation

A hub is not capable of making forwarding decisions. It simply broadcasts data to all connected devices without any intelligence to determine the best path.

What is the primary function of a Bridge (Layer 2) in networking devices?

• To provide a wireless connection to mobile devices

• To operate at the data link layer and filter content by MAC addresses for interconnecting LANs

• To increase the range of wireless signals

• To convert digital signals into analog signals

Answer explanation

To operate at the data link layer and filter content by MAC addresses for interconnecting LANs

Which networking device allows wireless-capable devices to connect to a wired network?

• Modem

• Router

• Access Point (AP)

• Switch

Answer explanation

The correct networking device that allows wireless-capable devices to connect to a wired network is an Access Point (AP). It acts as a bridge between the wired and wireless networks, enabling seamless connectivity.

At which layer of the OSI model does an Access Point (AP) operate?

• Network Layer

• Physical Layer

• Data Link Layer

• Transport Layer

Answer explanation

An Access Point (AP) operates at the Data Link Layer of the OSI model, responsible for connecting devices within the same network and managing wireless communication.

What does the term "Ad-Hoc" refer to in the context of wireless LAN configurations?

• A) A network setup where each computer can only connect through a wired connection.

• B) A network configuration where computers are connected directly to each other without an intermediary device.

• C) A network setup that requires a central server to manage connections.

• D) A network configuration that can only operate with internet access.

Answer explanation

The term 'Ad-Hoc' in wireless LAN configurations refers to a network configuration where computers are connected directly to each other without an intermediary device, making option B the correct choice.
