220-801 Question #972: Real Exam Question with Answer & Explanation
The correct answer is C: Cable. Among the listed options, cable internet consistently offers the highest bandwidth and transmission speeds for residential connections. Dial-up is the slowest, satellite has high latency, and DSL speeds are limited by distance from the central office.
Question
Which of the following Internet connection types would have the MOST available bandwidth and highest transmission speed?
Options
- ADSL
- BDial-up
- CCable
- DSatellite
Explanation
Among the listed options, cable internet consistently offers the highest bandwidth and transmission speeds for residential connections. Dial-up is the slowest, satellite has high latency, and DSL speeds are limited by distance from the central office.
Common mistakes.
- A. DSL (Digital Subscriber Line) uses telephone lines and its bandwidth degrades significantly with distance from the provider's central office, limiting maximum real-world speeds.
- B. Dial-up uses a standard analog telephone line to connect at a maximum speed of 56 Kbps, making it the slowest internet connection type available.
- D. Satellite internet has high latency due to the round-trip signal distance to orbiting satellites and historically lower bandwidth compared to cable, though newer LEO services are improving this.
