CompTIA Network+ (N10-009) — Question 249

A user attempts to log in to a corporate website by utilizing a shortcut. The shortcut has been used many times before. The user then notices some discrepancies on the company website. Which of the following is most likely the reason for this issue?

Answer options

• A. VLAN hopping
• B. ARP spoofing
• C. DNS poisoning
• D. MAC flooding

Correct answer: C

Explanation

The correct answer is C, DNS poisoning, as it involves corrupting the DNS cache to redirect users to fraudulent websites, which could explain the discrepancies noticed by the user. The other options, while related to network security, do not directly pertain to issues arising from DNS resolution and would not cause visible discrepancies on the website.
