13. Active Directory (AD), a Microsoft technology, is a distributed database that stores objects in a hierarchical, structured, and secure format. AD's objects typically represent users, computers, peripheral devices, and network services. Each object is uniquely identified by its name and attributes. DNS has a tree structure (hierarchical) where each branch represents the root zone and each leaf has zero or more resource records. Each zone represents a root domain or multiple domains and subdomains. A domain name consists of one or more parts, called labels, and these are separated by points (for example, packtpub.com). DNS is maintained by a database that uses distributed clients/server architecture where network nodes represent the servers' names.
14. Both Accounts, Global, Domain Local, Permissions (AGDLP) and Accounts, Global, Universal, Domain Local, Permissions (AGUDLP) are Microsoft's recommendations for effectively using group nesting when assigning permissions.
