Designing Cisco Data Center Infrastructure (DCID) — Question 35
Which type of encoding is used on 8-Gbps links as compared to 10-Gbps links?
Answer options
- A. 8-Gbps links use 64B/66B encoding, and 10-Gbps links use 8B/10B encoding.
- B. 8-Gbps links use 8B/10B encoding, and 10-Gbps links use 64B/66B encoding.
- C. 8-Gbps links and 10-Gbps links use 8B/10B encoding.
- D. 8-Gbps links and 10-Gbps links use 64B/66B encoding.
Correct answer: B
Explanation
The correct answer is B because 8-Gbps links use 8B/10B encoding, which is more efficient for that speed, while 10-Gbps links utilize 64B/66B encoding to support higher bandwidth. The other options are incorrect as they misrepresent the encoding schemes associated with the respective link speeds.
