Most of the dump are available. I have practiced the dump of 305 questions once,
The dump of 530 questions has not been fully practiced, and the answers to some questions in the dump  are not correct
Today, I came across a new multiple-choice question that none of the dump have, BGP routing reflector. I didn‘t review it.
