A network technician connects three temporary office trailer - CompTIA-N10-009
Question
A network technician connects three temporary office trailers with a point-to-multipoint microwave radio solution in a wooded area. The microwave radios are up, and the network technician can ping network devices in all of the office trailers. However, users are complaining that they are experiencing sporadic connectivity. What is the MOST likely cause of this issue?

Explanation
Correct Answer: B. Interference
- Interference is the most likely cause of sporadic connectivity in a point-to-multipoint microwave radio setup, especially in a wooded area. Microwave radio signals can be disrupted by:
- Trees and foliage, which can attenuate or scatter the signal.
- Environmental factors such as weather (rain or snow) or nearby wireless devices operating on the same frequency.
Even if the radios are functioning, interference can cause intermittent drops in signal quality, leading to sporadic connectivity issues for users.
Why the other options are incorrect:
-
Throttling:
- Throttling intentionally reduces bandwidth usage, typically implemented by ISPs or network administrators to manage traffic. This is unlikely in the scenario as the issue is described as sporadic, not a controlled reduction in bandwidth.
-
Latency:
- Latency refers to delays in network communication. While it can cause slow performance, it is not the primary cause of sporadic connectivity. Latency in this setup would generally be constant and not sporadic.
-
Split Horizon:
- Split horizon is a routing protocol rule used to prevent routing loops by prohibiting a router from advertising a route back to the interface from which it was learned. It has no relevance to microwave radio connectivity or the described issue.
