Which of the following statements are false about direct TCP offload engine (DTOE) 1.

A is true, so it is not selected. Huawei training material states that DTOE 1.0 uses polling mode to reduce latency .

B is true, so it is not selected. Huawei training material states that the hardware queue is operated in user mode , which helps avoid context-switching overhead .

C is false, so it must be selected. The same Huawei material explains that DTOE 1.0 is designed to eliminate traditional overheads such as kernel-mode interrupts, locks, system calls, and thread switching . Therefore, saying that these high-latency overheads still exist is incorrect.

D is false, so it must be selected. Huawei material lists the traditional problem that the CPU must spend great resources processing each MAC frame as a challenge of the conventional approach. DTOE 1.0 addresses this by offloading processing, so saying DTOE 1.0 still requires the CPU to process each MAC frame is incorrect.
