Exam SY0-501 topic 1 question 314 discussion

This is wireless jamming. You broadcase a opposite polarity on same freq to cancel the Ap's signal out. has nothing to do with SIN, SIN is for TCP.

interference is the keyword. C is correct

… Occasionally, a wireless network can experience interference from another wireless device, which can occur, for example, when two wireless access points are using adjacent frequencies or channels. Interference can interrupt and interfere with wireless network transmission and reception. For the most part, this interference is unintentional. Jamming is a form of intentional interference on wireless networks, designed as a denial-of-service (DoS) attack. This type of attack is perpetrated by overpowering the signals of a legitimate wireless access point, typically using a rogue AP with its transmit power set to very high levels. ...

Question says "Interference" ... should be C

Answer C. This is trying to test if you understand that clashing wireless network bands and channels can cause network interference either on purpose (as and attack) or by accident. A quick google for channel interference: “Channel Interference. If you and your neighbor are both using the same or nearby network channel for your wireless network, your wireless signals can clash, resulting in interference that can slow down your network”

the question didn't mentioned it's wireless network, so D is the correct answer because the key word is "using interference as its main attack to impede network traffic".

Jamming/Interference Wireless interference basically means disruption of one's network. This is a very big challenge especially owing to the fact that wireless signals will always get disrupted. Such interference can be created by a Bluetooth headset, a microwave oven and a cordless phone. This makes transmission and receiving of wireless signals very difficult. Wireless interference can also be caused by causing service degradation so as to make sure that one denies complete access to a particular service. Jamming can also be used in conjunction with an evil twin. Combating interference should be one's primary goal in case in happens. One way can be through the use of a spectrum analyser so as to narrow down to what could be causing the jamming problem. One can use simple software to examine one's traffic. However, using some of the spectrum analysers might not be so much easy and therefore some training is required.

I am not sure what in question tells that it is a wireless network ..

D. Inundating a target system with SYN requests

Why not d???
