The question doesn't say that the utility companies device is connected to the residents personal home WiFi, therefore you should assume it wouldn't be on their network. No company would be stealing paid internet service from their customers.

That would make more sense if the WAP was an 802.11b/g or n working at 2.4Ghz....the 5Ghz band (of the 802.11ac) shouldn't be prone to interference...But what do I know? the smar reader could be working on the 5Ghz as well...

I think it's C. From an article: "The smart meters use the unlicensed 2.4GHz frequency band. So if a Wi-Fi router or other device, overlaps on the same channel, there can be some interference, according to Central Maine Power. The problem can be addressed by moving devices away from the smart meter or changing the channel that electronics use, the utility says in its smart meter FAQ."

its not possible for (C) to be the answer i did some research and No. Smart meters use an entirely separate, wireless system. You don't need Wi-Fi in your home for it to work and it won't use your Wi-Fi if you have it. so how can this (C) be the right answer it wont affect home wireless because it doesn't use wifi so it cant affect wireless losing connectivity

I think the correct answer is (D) only because when it says company has installed a wireless device that was when the issue with 802.11ac home wireless intermittently loses connectivity when the device was installed DDOS attacks is focused on disabling the continuity of communication of devices connected to a network, affecting the switched flow tables, data on a network, bandwidth and latency (D) makes so much sense then the other options but this is just my opinion !!!

throttling and additional data being send would only slow down, it wouldn't disconnect right ? Therefore i will go with C.

In order to keep your sanity with these questions, perform a process of elimination. The last answer standing is the one, regardless of how improbable it sounds.
