Passed the exam - these questions are similar to the ones in the exam (some of these questions are very similar to the ones in the exam but there were questions in the exam way complicated than this). One of the labs (question 77) in these questions came up in my exam. The questions in the exam are tricky make sure you understand each concept in the exam objectives.

This new version of the exam is pretty tricky. You can tell by going over these questions. I really had no chance of passing if I had not used this exam dump. Questions are pretty valid as of this week.

Purchased the full version of this exam dump in PDF with the 50% sale on Black Friday. Got 2 exam for the price of one. Today I sat for this exam and as soon as I saw the first questions I was about to jump out of my seat. The questions are word by word the same. Got 98% in my result. Very happy.

Do not book your exam if you don't know the topics and the questions. The test is super duper hard and almost impossible to pass without knowing the questions.
