Which term describes an attack that floods a target with nonlegitimate service requests to exhaust resources and make services unavailable?

• A. DoS attack
• B. DDoS attack
• C. Zombie agents
• D. Volumetric Attacks

Answer: (A)

A Denial of Service attack describes flooding a target with illegitimate requests to exhaust its resources—like bandwidth, CPU, memory, or connection slots—so legitimate users can’t access the service. The goal is to make the service unavailable by overloading it. If the flood comes from many machines, that would be a distributed Denial of Service attack. The term volumetric attacks refers to high-volume traffic methods used in DDoS campaigns, not the general name of the attack itself. Zombie agents are the compromised hosts used to generate such traffic, not the attack type. So the best fit for the description is a Denial of Service attack.
