Numerous MAC resolution requests to create a buffer-overflow attack

Which of the following type of attacks sends out numerous MAC resolution requests to create a buffer-overflow attack?

A. DDoS
B. Smurf
C. ARP Poisoning
D. DNS poisoning

The answer is "C" but I thought ARP Poisoning is changing the ARP entries in the ARP cache to launch a man-in-the-middle attack or a DoS attack?

Yes, but that is caused by sending an ARP reply with a bogus MAC address for the default gateway. I've not heard ARP poisoning defined as numerous MAC resolution requests to create a buffer-overflow attack (does this change the ARP cache?).

Excuse me, I mean DoS. ARP can't be used for a DDoS, but it can be used to cause a situation where client machines do not have access to any resources by just dropping everything.

Remember a DoS doesn't nessesarily mean you overwhelm the buffer of the victim machine. Denial of Service - Hakipedia

What I don't understand is the question's/Answer's implication there is (1) a type of DNS poisoning attack that (2) sends out numerous MAC resolution requests to create a buffer-overflow attack. How are (1) and (2) related?

Based on this and your other thread on Spoofed Website Cause, it seems like you're using practice test questions that don't have explanations. I don't know this but am just assuming that's the case because you're asking for explanations.

I've written literally thousands of questions and know that while writing the explanations, flaws in the question reveal themselves and the questions you're posting seem flawed. For example, I don't know of any buffer overflow attack caused by ARP packets.

Practice test questions can provide two great benefits.

1) They help you test your readiness with realistic questions. If you can look at each answer and can explain why it is correct or incorrect, you're better prepared for the live exam no matter how CompTIA words the actual questions.

2) They help people learn when they are combined with explanations. If you can't determine why an answer is correct or incorrect, the explanation gives some additional knowledge to help you understand.

However, if they don't have explanations, they often cause confusion. You could spend hours trying to prove why a correct answer is correct, or an incorrect answer is correct in a question that simply doesn't have a correct answer. Worse, when people just memorize the answer (I'm not saying your are), they're often memorizing incorrect information.

If this source is working for you, by all means continue. However, if explanations aren't included, you might want to supplement it with something else before taking the live exam.

Good luck.

Thanks for the thorough feedback. Actually, these questions do have verbal feedback as part of a Security+ exam prep webinar offered by Brookline college through BrightTALK: brookline college | BrightTALK

Unfortunately, the host is sometimes not very informative with his explanations (probably in cases where the question is poor). In those cases, I bring the questions here because this group is such an excellent knowledge resource.

I completely agree with Darril. Brain **** and free practice exams suck. Darril makes a very crucial statement in his books saying "Know the correct answer but know why the others are wrong answers" or something like that, lol. I'm sure you get the point. I bought Darril's Kindle edition for $9.95

You can download free "Kindle for PC" if you don't have a kindle.
