Large-scale (Campus) LAN Quiz

What is the geographical scope of a large-scale (Campus) LAN?

• It is not constrained to any geographical area.

• It is constrained to a fixed geographical area.

• It spans multiple cities.

• It is only within a single building.

Answer explanation

A large-scale (Campus) LAN is constrained to a fixed geographical area, typically within a campus or a specific location.

Which of the following technologies is NOT used in large-scale (Campus) LAN?

• Ethernet

• ATM

• MPLS

• FDDI

Answer explanation

MPLS is NOT used in large-scale LAN. Ethernet, ATM, and FDDI are commonly used technologies in Campus LAN setups.

What technologies are involved in the functioning of a large-scale (Campus) LAN?

• Switching and routing technologies

• Wireless communication technologies

• Satellite communication technologies

• Cellular network technologies

Answer explanation

Switching and routing technologies are involved in the functioning of a large-scale LAN, enabling data to be efficiently transmitted between devices within the network.

Which LAN topology uses a single central cable to which all network devices are attached?

• Ring

• Mesh

• Bus

• Star

Answer explanation

The correct choice is Bus because it uses a single central cable to which all network devices are attached.

In which LAN topology do data packets travel in a circular fashion from one computer to another?

• Bus

• Star

• Ring

• Mesh

Answer explanation

In a Ring LAN topology, data packets travel in a circular fashion from one computer to another, making it the correct choice for this scenario.

Which LAN topology features a central hub or switch to which all individual devices are connected?

• Mesh

• Bus

• Ring

• Star

Answer explanation

The LAN topology with a central hub or switch connecting all devices is a Star topology.

What is a common problem associated with basic LAN topologies?

• High security risks

• Scalability problems

• Excessive high costs

• Low data transfer rates

Answer explanation

Basic LAN topologies often face scalability problems due to limitations in expanding the network efficiently to accommodate growth.

What does the "Shared Bus - 10 Mbps" label in diagram (a) indicate about the network topology?

• Each device has a dedicated 10 Mbps connection.

• The total network bandwidth is 10 Mbps, which is shared among all devices.

• The network operates at 10 Gbps.

• The network can support up to 10 devices.

Answer explanation

The total network bandwidth is 10 Mbps, which is shared among all devices.

In diagram (b), what does the "Total capacity up to 10 Mbps" label suggest about the hub's operation?

• Each device can communicate at 10 Mbps simultaneously without bandwidth sharing.

• The hub can only connect to devices with a maximum speed of 10 Mbps.

• The hub has a total capacity of 10 Mbps, which is shared among connected devices.

• The hub increases the total network capacity to more than 10 Mbps.

Answer explanation

The hub has a total capacity of 10 Mbps, which is shared among connected devices.

Which of the following was NOT a factor stressing the capabilities of traditional (shared) LANs in the 1990s?

• Faster CPUs

• Faster Operating Systems

• Network-intensive applications

• Increased storage capacity

Answer explanation

Increased storage capacity was NOT a factor stressing traditional LANs in the 1990s, unlike faster CPUs, operating systems, and network-intensive applications.
