A denial-of-service attack on software is a type of attack that prevents the software from responding to normal requests by consuming system resources. When developing software, it is necessary to analyze the threats posed by denial-of-service attacks. Which of the following is not an attack method that needs to be considered? A. An attacker takes advantage of logical errors in the software by sending certain types of data, causing calculations to enter an infinite loop and keeping the CPU usage at 100%. B. An attacker uses scripts with multiple nested queries, which results in low query efficiency when there is a large amount of data; by sending numerous queries, the database’s response time is slowed down. C. An attacker exploits the fact that the software does not release connections automatically, by sending a large number of connections and thus exhausting the available concurrent connections, making it impossible to access the software. D. An attacker bribes personnel at the IDC to unplug the network cable connected to the server where the software is running, thereby preventing access to it；
