CompTIA Security+ (SY0-701) — Question 161

A company is experiencing a web services outage on the public network. The services are up and available but inaccessible. The network logs show a sudden increase in network traffic that is causing the outage. Which of the following attacks is the organization experiencing?

Answer options

• A. ARP poisoning
• B. Brute force
• C. Buffer overflow
• D. DDoS

Correct answer: D

Explanation

The correct answer is DDoS, as a Distributed Denial of Service attack floods the network with excessive traffic, making services unavailable. ARP poisoning, brute force, and buffer overflow attacks do not typically cause a sudden increase in traffic that leads to service inaccessibility.
