Hi all!
Bài thi này chắc chắn có trong kỳ thi switching đấy.
Câu này ******* làm sai ban ah!

[phongnn]

Chắc ******* cấu hình sai thôi. Đừng quá máy móc, chỉ xem câu lệnh thôi chứ bạn. Mấy câu này dễ mà. Chú ý nhé: Trong T K có 3 bài lab thì khi đi thi sẽ gặp 2 bài tương tự gần giống hệt như thế đấy.
