    Mình so với bài làm của mình thì đáp án ở đây không đúng 1 số câu. Mình cũng làm như bạn nhưng chấm điểm thì sai. Cụ thể là câu 6,8,14,20,14.( đây là mình xem kết quả những câu mình làm đúng và sai trong bảng điểm để tìm ra.

      Thân mến. Mình đã đọc cm của bạn và xem lại các câu trên. Mình sợ rằng mình đã đánh dấu nhầm. Thực tế là không phải vậy, đó là đáp án chuẩn của Cisco đưa ra sau khi bọn mình kết thúc kỳ học. Bạn hãy xem thử lại bạn có tích nhầm, hay câu hỏi mới xáo trộn thứ tự đáp án mà bạn ko để ý. Bạn hãy xem lại tất cả nhé. Vì Bài số 2 này rất đơn giản.
