CompTIA Security+ (SY0-501) — Question 988

A security administrator has received multiple calls from the help desk about customers who are unable to access the organization's web server. Upon reviewing the log files, the security administrator determines multiple open requests have been made from multiple IP addresses, which is consuming system resources.
Which of the following attack types does this BEST describe?

Answer options

• A. DDoS
• B. DoS
• C. Zero day
• D. Logic bomb

Correct answer: A

Explanation

The correct answer is A (DDoS) because a Distributed Denial of Service (DDoS) attack involves multiple systems making requests to overwhelm a target server. Options B (DoS) refers to a single source attack, while C (Zero day) and D (Logic bomb) pertain to different types of vulnerabilities and malicious software, not to the described scenario of resource consumption from multiple sources.
