CompTIA Network+ (N10-009) — Question 470

Employees report that website requests are being redirected to other websites that display different content than expected. Which of the following attacks is most likely causing this issue?

Answer options

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

Correct answer: C

Explanation

The correct answer is C, DNS poisoning, which occurs when an attacker corrupts the DNS cache, causing users to be redirected to malicious sites. Options A (MAC flooding) and D (VLAN hopping) are related to network access issues and do not directly affect URL redirection. Option B (ARP spoofing) may intercept traffic but does not typically alter DNS resolutions like DNS poisoning does.
