Basics of LAN (Local Area Network) and WAN (Wide Area Network) MCQs

LAN is a small, localized network, while WAN spans larger areas or even the globe.

A switch is commonly used to connect multiple devices within a LAN for communication and data sharing.

A router connects a LAN to the Internet, allowing devices in the LAN to access external networks.

The star topology connects all devices to a central hub or switch in a LAN.

In a LAN, "IP" stands for "Internet Protocol."

DHCP (Dynamic Host Configuration Protocol) is commonly used for assigning IP addresses dynamically within a LAN.

A LAN typically covers distances up to a few kilometers, such as within a building or campus.

A firewall is primarily used to filter and block unwanted network traffic.

A LAN (Local Area Network) is typically used within a single home or office and can be connected via Wi-Fi.

VPN (Virtual Private Network) technology is used to connect remote offices or sites securely in a WAN.

A DNS Server (Domain Name System Server) is responsible for translating domain names into IP addresses.

A WAN accelerator or optimization appliance is used to compress and optimize data for faster transmission over a WAN.

VPN (Virtual Private Network) technology allows multiple LANs in different physical locations to appear as a single unified network.

VoIP (Voice over IP) is typically used for voice and video transmission over IP networks in a WAN.

A modem is used to connect a LAN to an external WAN, such as an ISP's network.

A typical LAN can support data transmission speeds of 1 Gbps (Gigabit per second).

A wired WAN connection uses physical wires or cables to connect remote sites.

NAT (Network Address Translation) allows a LAN to connect to the Internet using a single public IP address while allowing multiple devices within the LAN to share private IP addresses.

The ring topology connects devices in a circular fashion, where each device is connected to exactly two other devices.

A Point of Presence (POP) in a WAN serves as a gateway to the Internet or other WANs.

PAN (Personal Area Network) is used for connecting devices within a personal workspace.

Latency refers to the delay in data transmission between points in the network.

In a network context, bandwidth refers to the speed of data transmission.

WAN protocols like PPP are used to establish and maintain communication over a WAN link.

A router is responsible for connecting multiple LANs within a single building or campus.

A gateway connects LANs to the Internet or other networks.

Topology refers to the physical or logical layout of the network.

A switch manages traffic between devices on the same LAN.

A load balancer distributes network traffic evenly across multiple servers or paths to optimize performance.

A typical Bluetooth PAN connection has a range of up to 30 meters.

VSAT (Very Small Aperture Terminal) is commonly used for connecting remote sites using satellite communication.

Ethernet technology allows data transmission over a LAN using light signals through fiber-optic cables.

A network bridge connects two or more network segments and filters traffic between them.

The bus topology connects devices in a linear fashion, where each device is connected to a single cable or bus.

A proxy server is used to improve network security and performance by acting as an intermediary between clients and servers.

4G LTE is a type of WAN connection that uses cellular networks to provide internet connectivity to remote sites or devices.

WAN protocols like MPLS are used to establish efficient communication paths within a WAN.

A router is used to connect multiple LANs within a building or campus and form an interconnected network.

Downtime refers to the time when network maintenance or outages cause unavailability.

DSL (Digital Subscriber Line) technology allows data transmission over traditional copper telephone lines.

Ethernet technology allows data transmission over a LAN using electrical signals over twisted pairs of copper wires.

In a WAN, throughput refers to the speed of data transmission.

A DNS Server (Domain Name System Server) is responsible for translating domain names into IP addresses.

VPN (Virtual Private Network) technology allows multiple LANs in different locations to connect securely over the Internet.

A CSU/DSU (Channel Service Unit/Data Service Unit) converts digital data from LANs into a format suitable for WAN transmission.

The ring topology connects devices in a circular fashion, where each device is connected to exactly two other devices.

T1 is commonly used for point-to-point communication over long distances in WANs, often by telecommunications providers.

NAT (Network Address Translation) allows multiple devices in a LAN to share a single public IP address for external communications.

Ethernet technology allows data transmission over coaxial cables with a central bus or trunk line.

A Multiplexer is used to combine multiple data streams onto a single communication channel in a WAN.
