CompTIA Project+ (PK0-005)Basics of IT and GovernanceMedium
A project manager is overseeing the deployment of a new supply chain management system that will integrate with various third-party logistics providers. The system needs to be able to exchange data reliably and securely with these external partners, often across different network architectures and geographical locations. Which fundamental IT infrastructure component is crucial for enabling this widespread, interconnected communication?
- AStorage Area Network (SAN)
- BContent Delivery Network (CDN)
- CWide Area Network (WAN)
- DLocal Area Network (LAN)
Show answer & explanationAnswer & explanation
Correct answer: C. Wide Area Network (WAN)
A Wide Area Network (WAN) connects local area networks (LANs) over large geographical distances, making it essential for enabling communication and data exchange between an enterprise and its geographically dispersed third-party partners.
Why the other options are wrong
- A. A SAN is a dedicated high-speed network for block-level storage, unrelated to general inter-organizational communication.
- B. A CDN optimizes content delivery by caching data closer to users, not for enabling core inter-organizational network communication.
- D. A LAN connects devices within a limited geographical area, like a single office, not widespread partners.
Wide Area Network (WAN)
A telecommunications network that extends over a large geographical area, often connecting multiple local area networks (LANs). It enables communication between offices, data centers, and external partners across cities, countries, or continents.
- Connects LANs over vast distances.
- Essential for global organizations and remote access.
- Utilizes various technologies like MPLS, internet, private lines.
Memory trick: LAN is Local, WAN is Wide.
