How does subnetting impact routing efficiency and broadcast domains in large-scale enterprise network architectures?

LAN (Local Area Network) covers a small area like a home, school, or office, while WAN (Wide Area Network) spans large areas such as cities or countries. LAN is generally faster and more reliable because devices are close together, whereas WAN is slower due to long-distance connections. LAN is used for local sharing of resources, while WAN connects multiple networks and enables global communication like the internet.

Outcomes addressed in this activity:

Unit Outcomes:

• Discuss how the CIA triad can be used when hardening a data network.
• Investigate the different types of network transmission.
• Describe the most common types of network attacks.
• Analyze how a network switch operates and the various configurations and services that can be enabled.

Course Outcome:

IT530-3: Analyze scenarios involving security groups and access to network resources

Purpose

The labs in Unit 6 address how to configure a routers interface and the need for NAT on a private network. Additional labs on how to manage a DoS attack and the steps to configure a VPN are also addressed.

Navigate to zyBooks and complete the following labs:

• 8.6 LAB: PAT
• 8.7 LAB: Port NAT
• 8.8 LAB: NAT
• 9.11 LAB: Denial-of-Service (DoS) Attacks
• 9.12 LAB: Virtual Private Network (VPN)

1-Question One

Define a Wireless Sensor Network (WSN) and describe the components of a wireless sensor node. Include figures to support your explanation.

2-Question Two

How can wireless sensor networks be categorized based on sensor network design and protocol implementation, considering key distinguishing features such as data sink characteristics, sensor mobility, sensor resources, traffic patterns, and taxonomy dimensions including spatial resolution, latency, coverage, temporal resolution, user types, and network lifetime?

3-Question Three

Differentiate between target detection, classification, and tracking in Wireless Sensor Networks. Provide one practical example.

4-Question Four

Discuss the main challenges of underwater wireless sensor networks (UWSNs) and explain how propagation delay affects communication.
