Answers

D.
Unauthorized access to resources
Answers
D.
Unauthorized access to resources
Suggested answer: B

Explanation:

Prevention of authorized access is the greatest threat posed by a distributed denial of service (DDoS) attack on a public-facing web server because it prevents legitimate users or customers from accessing the web services or resources, causing disruption, dissatisfaction, and potential loss of revenue or reputation. Execution of unauthorized commands is not a threat posed by a DDoS attack, but rather by a remote code execution (RCE) attack. Defacement of website content is not a threat posed by a DDoS attack, but rather by a web application attack. Unauthorized access to resources is not a threat posed by a DDoS attack, but rather by a brute force attack or an authentication bypass attack.
