A company is setting up a new office in a remote area where traditional wired broadband services are unavailable or prohibitively expensive. They need a WAN solution that can provide internet access for email, web browsing, and occasional video conferencing, despite potential higher latency. Which WAN technology is best suited for this scenario?
- AMetro Ethernet
- BMPLS VPN
- CSatellite Internet
- DT1/E1 Leased Line
Show answer & explanationAnswer & explanation
Correct answer: C. Satellite Internet
Satellite Internet is ideal for remote locations where terrestrial internet infrastructure is lacking. While it typically has higher latency, it provides wide coverage and can deliver sufficient bandwidth for common business applications like email, web browsing, and even video conferencing, making it suitable when other options are unavailable.
Why the other options are wrong
- A. Metro Ethernet requires existing fiber infrastructure, which is unavailable in the scenario.
- B. MPLS VPN is a carrier-grade service requiring a provider network, which is unlikely to be available where wired broadband is absent.
- D. T1/E1 leased lines are expensive, offer limited bandwidth compared to modern needs, and also require terrestrial infrastructure.
Satellite Internet
A WAN technology that uses communication satellites to provide internet access, typically used in rural or remote areas.
- Offers wide geographic coverage.
- Typically has higher latency due to signal travel distance.
- Can be affected by weather conditions.
- Often a last-resort option where wired broadband is unavailable.
Memory trick: When roads end, look to the sky for internet.
