What does ADWS stand for?
active domain windows server (active directory windows services?)
This provides the methods for storing directory data and making this data available to network users and administrators. For example, it stores information about user accounts (names, passwords, phone, numbers, etc.), and enables other authorized users on the same network to access this information.

What does FQDN stand for?

These are complete addresses of websites, computers, and other entities that can be accessed on the internet.
fully qualified domain names
An FQDN consists of 3 labels including:
- hostname

www - hostname
facebook - SLD
com - TLD
What is the final period in a fully qualified domain name?
trailing period
What does OU stand for?
organizational unit
Used to indicate an address of a website. However, it only refers to one or two labels from an FQDN (either hostname or the domain name)
partially qualified domain name
This is a subdivision within an active directory into which you can place users, groups, computers, and other of its kind.
organizational unit
What does LDAP stand for?
lightweight directory access protocol
This is a protocol that makes it possible for applications to query user information rapidly.

What does GC stand for?
global catalog
It allows users and applicatons to find objects in an active directory domain tree, given one or more attributes of the target object.
global catalog
What does RODC stand for?
read-only domain controller
This is a new type of domain controller that hosts read-only partitions of the active directory database.

What does UPN stand for?

This is a username and domain in email address format within Microsoft AD.
user principal name
This is the component of the distinguished name (DN)
relative distinguished name (RDN)
This is a fully qualified path of names that trace the entry back to the root of the tree.
distinguished name
Benefit of having a single domain
Having a single directory service or global catalog (GC) means this for all other directory-aware services, including messaging and monitoring.
single foundation
Benefits of having a single domain
Having this means there is just one infrastructure for all other directory services atasks, such as software deployment, inventory, and object management sharing and delegation (such as for user accounts)
single management infrastructure
Benefits of having a single domain
This means that management policies need to be defined only once, and can be used throughout the entire enterprise without the need to manually export and import Group Policy Objects (GPOs)
single group policy container (GPC)
Benefits of having a single domain
Having a single domain means better resilliency because every location has a full domain backup.
backup and recovery
Benefits of having a single domain
Having a single domain means better ____ through a single ____ policy and a set of administrators. If you have multiple domains and forests, each hast its own administrators. One weak but trusted domain exposes all the other forests and domains. With only a single domain, it’s also far easier to enforce an organization-wide ____ policy.
security
Benefits of having a single domain
In an organization with multiple domains, every location needs two domain controllers (DCs). With a single domain, each location needs only a single DC because if the local DC fails, the locations can use hub DCs.
less hardware
Benefits of having a single domain
Initiatives in an organization with just a single domain and shared account database solutions need only be deployed once, which means company-wide deployments are much faster than if the organization has multiple and separate domains.
faster deployment of company initiatives
True or false?
Having only one domain controller is recommended because it does not create a single point of failure.
FALSE: It does create a single point of failure.
This will load balance the services and minimize the risk of critical services going down.
second domain controller
