Question 17

Refer to the exhibit. During a post Mesh deployment survey, an engineer notices that frame collisions occur when MAP-1 and MAP-3 talk to RAP-2. Which type of issue does the engineer need to address in the design?

    Correct Answer: B

    The issue described in the question involves frame collisions when two points (MAP-1 and MAP-3) communicate with a central point (RAP-2). This situation is indicative of the hidden node problem, where MAP-1 and MAP-3 are unable to detect each other's transmissions to RAP-2, causing collisions. The hidden node problem occurs when nodes A and C can communicate with node B but not with each other, leading them to attempt to send data simultaneously to B, resulting in collisions. Therefore, the correct answer is the hidden node problem.
