CompTIA Project+ (PK0-005)Basics of IT and GovernanceEasy
A project manager is overseeing the implementation of a new inventory management system. The system requires real-time data synchronization across multiple geographically dispersed warehouses. Which IT infrastructure component is MOST critical to ensure low-latency and high-throughput communication between these locations?
- ALocal Area Network (LAN) switches within each warehouse.
- BWide Area Network (WAN) connectivity and optimization.
- CDatabase servers located in a central data center.
- DWireless access points (WAPs) for mobile scanners.
Show answer & explanationAnswer & explanation
Correct answer: B. Wide Area Network (WAN) connectivity and optimization.
The scenario explicitly mentions 'multiple geographically dispersed warehouses' and the need for 'real-time data synchronization' with 'low-latency and high-throughput communication.' This directly points to the function of a Wide Area Network (WAN), which connects disparate geographic locations.
Why the other options are wrong
- A. LAN switches manage local network traffic within a single site, not between dispersed sites.
- C. Database servers store data but don't manage the inter-site communication channel itself.
- D. WAPs provide local wireless access, not inter-site connectivity for real-time synchronization.
Wide Area Network (WAN)
A telecommunications network that extends over a large geographical area, connecting multiple local area networks (LANs).
- Used for inter-site communication.
- Often involves carriers like ISPs, using technologies such as MPLS, SD-WAN, or VPNs.
- Critical for distributed enterprises and cloud connectivity.
Memory trick: LAN is Local, WAN is Wide, MAN is Medium.
