FC0-U71 Practice Question: Which internet connection type provides symmetric…
Which internet connection type provides symmetric upload and download speeds over a fiber-optic cable?
⚠ Common exam trap
Candidates often confuse 'fiber' as a general term for any high-speed internet, but the question specifically tests the property of symmetric speeds, which is unique to fiber-optic connections among the listed options, not just a marketing label.

Correct answer & explanation
✓
Fiber
Fiber-optic internet (often referred to as Fiber-to-the-Home or FTTH) uses light pulses transmitted through glass strands to deliver data. Unlike DSL or cable, fiber connections are inherently symmetric, meaning they provide identical upload and download speeds because the technology does not rely on asymmetric frequency division or shared coaxial infrastructure. This makes fiber the correct answer for symmetric speeds.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Satellite
Why it's wrong here
Satellite internet has high latency and is typically asymmetric, not fiber-based.
- ✓
Fiber
Why this is correct
Fiber-optic cables provide symmetric speeds, often up to 1 Gbps or more.
- ✗
Cable
Why it's wrong here
Cable internet uses coaxial lines and is asymmetric; speeds vary with usage.
- ✗
DSL
Why it's wrong here
DSL uses telephone lines and typically offers asymmetric speeds (faster download than upload).

Asymmetric Encryption Algorithm Comparison
| Algorithm | Key Exchange | Signatures | Equivalent Security Key | Notes |
|---|---|---|---|---|
| RSA-3072 | Yes | Yes | 128-bit | Widely deployed; slow for bulk data |
| ECDSA P-256 | No | Yes | 128-bit | Fast signatures; standard TLS certs |
| ECDH / ECDHE | Yes | No | 128-bit | Perfect forward secrecy in TLS 1.3 |
| DH / DHE | Yes | No | 128-bit (3072-bit key) | Replaced by ECDHE in modern TLS |
| Ed25519 | No | Yes | ~128-bit | SSH keys, modern PKI |
