Exam 312-49v10 topic 1 question 531 discussion

I can see the case for D. CFHI V10 Manual on Economic Denial of Service pg 770. "The payment method employed in a cloud system is based on the “no use, no bill” policy; the CSP charges customers according to the data recorded when customers make requests, the duration of requests, amount of data transfer in the network, and the number of CPU cycles consumed. Economic denial of service destroys the financial resources; in the worst case, this could lead to customer bankruptcy or other severe economic impact. If an attacker deploys a malicious service or executes malicious code on a cloud system that consumes a significant amount of computational power and storage from the cloud server, the legitimate account holder is liable for paying for such consumption unless the service provider finds the primary cause of CPU usage."

D. EDoS Attack (Economic Denial of Service) The textbook explains that an EDoS attack focuses on causing financial harm by exploiting cloud resources, resulting in high costs for the victim. The attacker generates excessive traffic or resource consumption to increase the cloud service provider's bill, affecting the victim economically.

From EC Council V10 book: Economic denial of service destroys the financial resources; in the worst case, this could lead to customer bankruptcy or other severe economic impact. If an attacker deploys a malicious service or executes malicious code on a cloud system that consumes a significant amount of computational power and storage from the cloud server, the legitimate account holder is liable for paying for such consumption unless the service provider finds the primary cause of CPU usage. Cloud

I disagree with the answer. I think right one is D. EDoS Attack (Economic Denial of Service), mainly because DDoS implies "distributed" and there is just one system involved in.
