A company is setting up a new branch office in a remote location where traditional fiber optic or cable broadband services are unavailable. They require a WAN connection that can provide reliable connectivity, albeit with potentially higher latency, and can be quickly deployed. Which WAN technology would best suit these requirements?
- ADSL (Digital Subscriber Line)
- BT1/E1 Leased Line
- CSatellite Internet
- DMetro Ethernet
Show answer & explanationAnswer & explanation
Correct answer: C. Satellite Internet
Satellite Internet is ideal for remote locations where terrestrial services are unavailable, offering quick deployment and global coverage. The trade-off is often higher latency due to the long distance signals must travel to and from geostationary satellites.
Why the other options are wrong
- A. DSL relies on existing copper telephone lines, which may also be unavailable or provide insufficient bandwidth in very remote areas.
- B. T1/E1 leased lines require dedicated physical circuits that may not be available or quickly deployable in a remote location.
- D. Metro Ethernet requires existing fiber infrastructure, which is unavailable in this remote scenario.
Satellite Internet
A type of WAN connection that uses satellites in Earth's orbit to provide internet access, typically used in remote or rural areas where terrestrial options are limited.
- Global coverage, ideal for remote areas
- Quick deployment (dish installation)
- Higher latency due to signal travel distance
- Affected by weather conditions
Memory trick: Satellites reach where cables can't.
