Exam N10-008 topic 1 question 61 discussion

I think I know why its B... they mentioned "a high-rise building" which is a sky scrapper. with that kinda height there could be radio waves interference or distance of the AP from connected users causing intermittent connection. and EIRP is Equivalent isotropic radiated power, EIRP, is the total radiated power from a transmitter antenna times the numerical directivity of the antenna in the direction of the receiver. remember its a high rise building there could be huge distance from AP to connected user which can also cause the on and off connection. the AP EIRP needs to be boosted to distribute signals to distant connected users

High rise is not a distraction, it is the reason why C is the answer because in a high rise there are other tenants in the building causing multiple wifi to overlap in the same channel.

overlap makes sense

Key words Several APs are mounted in this office

I think it's C. it's not B because its a small office and has several APs mounted. Channel overlapping is likely the cause.

The most likely cause of the frequent disconnections and reconnections in a high-rise building with multiple APs is channel overlap. In densely populated areas, such as high-rise buildings, multiple wireless networks can interfere with each other if they are operating on the same or overlapping channels12. To mitigate this issue, the technician can: Adjust Channel Settings: Ensure that the APs are set to non-overlapping channels (e.g., channels 1, 6, and 11 for 2.4 GHz). Perform a Site Survey: Use a wireless analyzer to identify the least congested channels and adjust the APs accordingly. Reduce Transmit Power: Lower the transmit power of the APs to minimize interference with neighboring networks.

C is the correct answer

Correct answer is C In a high-rise building with multiple Access Points (APs), frequent disconnections and reconnections are often caused by *channel interference*. This can occur when multiple APs are using overlapping or the same wireless channels, which can lead to interference and poor connectivity. Here’s a more detailed explanation of why channel interference is likely the most common issue in this scenario: Channel Overlap: In a high-rise environment, multiple APs are typically required to provide coverage. If these APs are configured to use overlapping or the same channels, their signals can interfere with each other. This interference can cause devices to experience intermittent connectivity problems as they struggle to maintain a stable connection.

C. It’s a small, singular office inside a building. There are, more than likely, other offices inside the building. I’m sure they’re running their own APs

The symptoms described suggest interference or congestion issues in the wireless network environment. Given that several access points (APs) are mounted in the office, the most likely cause of the frequent disconnections and reconnects is: C. Channel overlap is occurring Channel overlap happens when adjacent wireless access points use overlapping frequency channels. This can lead to interference and reduced performance, causing devices to disconnect and reconnect frequently as they try to find a clear channel or a stronger signal. Therefore, option C, channel overlap, is the most likely cause of the reported wireless connectivity issue in the small office located in a high-rise building with multiple APs.

Channel overlap is occurring. If you have two device with the same channel and close to one and other, you device will drop from one AP to the other. as well as having channels over lapping the devices will fight with one and other.

C. Channel overlap is occurring: In environments where multiple APs are used, especially in close proximity such as in a small office in a high-rise building, channel overlap can cause interference. This is because multiple APs may be broadcasting on the same or adjacent channels, leading to signal interference. This interference can cause devices to disconnect from one AP and attempt to reconnect to another that may appear to have a stronger signal momentarily.

C. Channel overlap is occurring In a scenario where multiple access points (APs) are installed in close proximity, channel overlap can be a significant issue. Channel overlap occurs when neighboring APs are using the same or overlapping frequency channels. This can lead to interference and signal degradation, resulting in frequent disconnections and reconnects for wireless devices.

Equivalent Isotropic Radiated Power (EIRP) is the maximum power radiated from an ideal isotropic antenna giving off dBi. Using a spectrometer, you want to ensure the Received Signal Strength Indication (RSSI) on your device is between 0 to -100 (-30 being ideally close) dBm. Current signal strength could be disconnecting from signal attenuation that occurs at high altitudes.

Vertical overlap between AP's is causing the issue.

Chatgpt says the answer is C The frequent disconnects in a high-rise building with multiple access points (APs) could be due to interference or signal overlap between APs. Adjusting channels and ensuring proper spacing between APs might help resolve the connectivity issue.

I agree with C. "Several APs are mounted in this office"
