Huawei Certified ICT Associate – WLAN (HCIA-WLAN) — Question 29

On a WLAN where there are only one AP and two STAs, the two STAs can hear each other but one STA is not in the coverage area of the AP. For the AP, this STA is a hidden node.

Answer options

Correct answer: B

Explanation

The correct answer is B because a hidden node is defined as a device that cannot hear the transmissions from another device that it needs to communicate with through the AP. Since the STA that is out of coverage cannot communicate with the AP, it cannot be considered a hidden node from the AP's perspective. Therefore, A is incorrect.
