A project manager is overseeing the implementation of a new inventory management system for a retail chain. The system needs to be accessible from all store locations and the central warehouse. Which of the following network infrastructure components is primarily responsible for connecting these geographically dispersed locations?
- AWide Area Network (WAN)
- BStorage Area Network (SAN)
- CVirtual Private Network (VPN)
- DLocal Area Network (LAN)
Show answer & explanationAnswer & explanation
Correct answer: A. Wide Area Network (WAN)
A Wide Area Network (WAN) is specifically designed to connect networks over large geographical distances, making it suitable for linking multiple store locations and a central warehouse.
Why the other options are wrong
- B. SANs are specialized high-speed networks that provide block-level access to storage, not primarily for connecting disparate user locations.
- C. VPNs create secure connections over a public network but rely on an underlying network, often a WAN, to connect the locations.
- D. LANs connect devices within a limited geographical area, such as a single building or campus.
Wide Area Network (WAN)
A telecommunications network that extends over a large geographical area for the primary purpose of connecting multiple smaller networks (like LANs) or individual users.
- Connects geographically dispersed locations.
- Uses various technologies like leased lines, MPLS, or the internet.
- Essential for large organizations with multiple sites.
Memory trick: WAN spans the World And Networks.
