GCIH · Question #119

A user is sending a large number of protocol packets to a network in order to saturate its resources and to disrupt connections to prevent communications between services. Which type of attack is…

The correct answer is D. Denial-of-Service attack. Flooding a network with packets to exhaust resources and disrupt legitimate connections is the defining characteristic of a Denial-of-Service (DoS) attack.

Why each option

Flooding a network with packets to exhaust resources and disrupt legitimate connections is the defining characteristic of a Denial-of-Service (DoS) attack.

AVulnerability attack

A vulnerability attack exploits a specific flaw or weakness in software or hardware to gain unauthorized access, not to flood resources with traffic.

BImpersonation attack

An impersonation attack involves an attacker masquerading as a trusted entity to gain access or intercept communications, unrelated to flooding traffic.

CSocial Engineering attack

Social engineering manipulates people psychologically to divulge information or perform actions, and does not involve sending protocol packets to a network.

DDenial-of-Service attackCorrect

A Denial-of-Service attack deliberately overwhelms a target's network, bandwidth, or processing resources by sending a high volume of traffic or malformed packets. The goal is to saturate capacity so legitimate users and services cannot communicate, exactly matching the described behavior of sending large numbers of protocol packets to disrupt connections.
