DoS network attacks are fairly uncommon.

• A. False
• B. True
• C. Often
• D. Rarely

Answer: (A)

The main idea here is how common a Denial of Service attack really is. DoS attacks aim to exhaust a target’s resources (bandwidth, CPU, memory) so legitimate users can’t access a service. In the real world, these attacks are not rare; they are a frequent threat. With tools that automate traffic floods and the widespread use of botnets, attackers can launch both DoS and distributed DoS (DDoS) attacks against many organizations, from small sites to large networks. Because of this accessibility and scale, many networks face at least occasional DoS attempts, and high-profile incidents keep DoS in the security spotlight. So saying these attacks are fairly uncommon understates their prevalence, making the statement false.
