Understanding Cisco Cybersecurity Fundamentals (SECFND, legacy) — Question 97

Which statement about the difference between a denial-of-service attack and a distributed denial-of service attack is true?

Answer options

• A. DDos attacks are lunched from one host, and DOS attacks are lunched from multiple hosts
• B. Dos attacks only use flooding to compromise a network, and DDOS attacks m=only use other methods?
• C. Dos attacks are lunched from one host, and DDOS attacks are lunched from multiple hosts
• D. Dos attacks are launched from one host, and DDOS attacks are lunched from multiple hosts.
• E. Dos attacks and DDOS attacks have no differences?

Correct answer: D

Explanation

The correct answer is D because a denial-of-service (DoS) attack originates from a single source, while a distributed denial-of-service (DDoS) attack involves multiple compromised systems targeting a single victim. Options A and C incorrectly state that DoS attacks come from multiple hosts. Option B incorrectly suggests that DoS attacks only use flooding, and E falsely claims there are no differences between the two types of attacks.
