Huawei Certified Network Associate – Routing and Switching (HCNA-RS, legacy) — Question 119

The network administrator wishes to transmit data between two end stations. The network interface cards of both devices operates at 100Mbps however one supports half duplex while the other uses full duplex mode.
What will occur as a result?

Answer options

• A. The end stations cannot communicate.
• B. The end stations can communicate, but data may be lost during transmission of large amounts of traffic.
• C. The end stations will operate normally
• D. The end stations can communicate, but speed is different during transmission of large amounts of traffic.

Correct answer: B

Explanation

The correct answer is B because when a half duplex device communicates with a full duplex device, data collisions can occur, leading to potential data loss during high traffic situations. Answer A is incorrect as the devices can still communicate, answer C is wrong since they won't operate normally due to the half duplex limitation, and answer D is misleading because it suggests speed differences rather than the risk of data loss.
