PBQ: Network Design

Scenario

A network administrator has been tasked with designing a network for a new corporate office. The office consists of two buildings separated by 150 feet with no physical connectivity. The configuration must meet all of the following requirements:

Devices in both buildings must be able to access the Internet
Security insists that all Internet traffic be inspected before entering the network
Desktops should not see traffic destined for other devices
Wireless coverage is needed in Building B's conference room
Building A needs a dedicated server room with high-speed switching
A remote wiring closet in Building A must extend the network without sharing bandwidth

Device Reference

Device	Primary Function
Firewall	Inspects and filters traffic based on rules; blocks unauthorized access at the network perimeter
Router	Routes packets between different IP networks; determines the best path between subnets
Switch	Forwards frames based on MAC addresses; provides dedicated bandwidth per port (no shared collision domain)
WAP	Provides wireless (802.11) access for clients; connects back to the wired switch via uplink
Hub	Repeats all traffic to every port; shares bandwidth; creates a single collision domain
Wireless Range Extender	Rebroadcasts an existing wireless signal to extend range; does not connect new wired infrastructure
Media Converter	Converts between physical media types (e.g., copper to fiber)
Load Balancer	Distributes incoming traffic across multiple servers to improve availability and performance
