A project manager is overseeing the implementation of a new inventory management system across several geographically dispersed warehouses. The system requires real-time data synchronization and high availability to prevent stock outages. Which of the following network infrastructure components is MOST critical for ensuring reliable and efficient data exchange between these distant locations?
- AVirtual Local Area Network (VLAN)
- BStorage Area Network (SAN)
- CWide Area Network (WAN)
- DLocal Area Network (LAN)
Show answer & explanationAnswer & explanation
Correct answer: C. Wide Area Network (WAN)
A Wide Area Network (WAN) is designed to connect geographically dispersed locations, making it essential for synchronizing data between distant warehouses. LANs connect devices within a limited area, SANs manage storage, and VLANs segment networks virtually.
Why the other options are wrong
- A. VLANs logically segment a single physical network, but do not connect geographically separate sites.
- B. SANs are specialized networks for connecting storage devices to servers, not for connecting distant user locations.
- D. LANs connect devices within a limited geographical area, not distant locations.
Wide Area Network (WAN)
A telecommunications network that extends over a large geographical area, such as across cities, regions, or countries, to connect multiple Local Area Networks (LANs).
- Connects geographically dispersed locations.
- Essential for large organizations with multiple sites.
- Often uses public or leased lines for connectivity.
Memory trick: WANs span the globe, connecting distant points like a web.
