A Wide Area Network (WAN) is a network that exclusively uses wireless technology for communication.

A Wide Area Network (WAN) is a local network connecting devices within a single building.

A Wide Area Network (WAN) is a network that covers a broad area, connecting multiple smaller networks.

A Wide Area Network (WAN) is a type of network that only connects devices in the same room.

Bluetooth

MPLS, Frame Relay, ATM, PPP, HDLC

Wi-Fi

Ethernet

Reduces data transfer speeds.

Limits communication to local areas.

1. Enables communication over long distances. 2. Facilitates centralized data management and resource sharing.

Increases hardware costs significantly.

LAN connects multiple WANs over short distances.

WAN connects multiple LANs over large distances, while LAN is confined to a small area.

WAN is a type of LAN that operates locally.

WAN is faster than LAN in all scenarios.

Establishing a local area network

Transmitting data over short distances

Connecting branch offices to a central corporate network

Connecting devices within a single building

Routers connect and manage data traffic between multiple LANs in a WAN, ensuring efficient communication and routing of data packets.

Routers only connect devices within a single LAN.

Routers are responsible for physical layer connections in a WAN.

Routers are used to store data permanently in a WAN.

Bandwidth is significant in WAN as it affects data transfer speed and network performance.

Bandwidth is irrelevant to network security measures.

Bandwidth determines the physical distance of WAN connections.

Higher bandwidth always guarantees better reliability in WAN.

HTTP

FTP

SMTP

MPLS

Latency improves WAN performance by speeding up data transmission.

Latency has no effect on WAN performance whatsoever.

Latency only affects local area networks, not WANs.

Latency negatively impacts WAN performance by increasing delays in data transmission.

The purpose of a leased line in WAN is to provide a dedicated, reliable, and high-speed connection between two locations.

To provide a temporary connection for testing purposes.

To connect multiple locations over a shared network.

To reduce the cost of data transmission between locations.

A local business managing its internal network.

A single office using a high-speed internet connection.

A home user streaming videos online.

A multinational corporation sharing data between its headquarters and regional offices.

Security concerns associated with WAN include data interception, unauthorized access, device vulnerabilities, DDoS attacks, eavesdropping, and man-in-the-middle attacks.

Firewall configurations

Network redundancy techniques

Data encryption methods

Satellite connections are only used for television broadcasting.

Satellite connections are used to establish WANs, especially in remote areas.

WANs cannot be established using any type of satellite technology.

Satellite connections are primarily for local area networks (LANs).

Distance improves signal quality in WAN connectivity.

Distance increases latency and can degrade signal quality in WAN connectivity.

Distance has no effect on WAN connectivity.

Distance only affects local area networks (LANs).
