Hello, I have been training the ITIL Aspirants for more than 2 decades now: Did You Know, what is the secret of passing the exam in first attempt? That it, Understand the concept and Practice the Questions. Which is why I have written this guide this way, Explaining the Concept in Simple Words and Providing Practice Questions to Concretize the Concept in your mind. So, Read, Learn and Pass. I wish to see you certified ASAP. Remember: "Understand the concept and Practice the Questions." is your MANTRA for Success. Good Luck!!
