This is the end of the introductory chapter on Active Directory fundamentals. I am sure most of you are already aware about most of the functions of AD DS. But refreshing your knowledge about Active Directory components and their operations before we deep dive into the advanced topics wasn't in vain. In this chapter, we also covered Active Directory objects, GUID and SID values, and DN. Later, I explained the Active Directory server roles and their core values.

In the next chapter, you will learn about new features and enhancements to AD DS 2016, specifically about the new approach to protect identities from modern security threats.
