Implementing and Operating Cisco Security Core Technologies (SCOR) — Question 255

What is the intent of a basic SYN flood attack?

Answer options

• A. to solicit DNS responses
• B. to flush the register stack to re-initiate the buffers
• C. to exceed the threshold limit of the connection queue
• D. to cause the buffer to overflow

Correct answer: C

Explanation

The correct answer is C because a SYN flood attack aims to overwhelm the connection queue by sending a large number of SYN requests, exceeding its capacity. Options A, B, and D do not accurately describe the specific mechanics or intent of a SYN flood attack, making them incorrect.
