In this course, we'll be talking about domain controllers.
We'll take a look at what the main controller is and what is a global catalog.
We'll have overview of domain controller as service records and much more.
But before we begin, let's have a look at two quick questions to find out if you already know this
information.
So the question is, should a domain controller bear a global catalog?
Take your time and press pause here to think about it.
And the answer is global catalog placement affects how long a user takes to sign in.
Therefore, you must carefully plan how to place global catalogs in a single domain environment.
Every domain controller should host the global catalog because every domain controller already holds
a complete copy of the domain in a multiple domain scenario.
You need to consider user sign in times program dependencies the need for high availability of the global
catalog and replication traffic when planning global catalog placement.
Now, another question In a multiple domain forest, a copy of the global catalog should be stored on
every domain controller.
Is it true or false?
And the answer is false.
In a single domain, you should configure all domain controllers to hold a copy of the global catalog.
However, in a multiple domain environment, the infrastructure master should not be a global catalog
server unless all the domain controllers in the domain are also global catalog server.
So please remember this information and consider when planning your infrastructure.
Now some words about this course.
Overview.
Or better to say this section Overview which is overview of ads domain controllers.
Because domain controllers authenticate all users and computers in the domain.
Domain controller deployment is critical for the network to function correctly.
This section examines domain controllers, the assigning process, and the importance of the DNS and
that process.
In addition, this section discusses the purpose of the global catalog.
All domain controllers are essentially the same, with two exceptions raw DC that is read only domain
controllers.
They contain a redundant copy of the ads database, whereas other domain controllers have a read write
copy.
Also, certain operations can be performed only on specific domain controllers, which are called operations
masters, and it will be discussed at the end of this section.
After completing this section, you'll be able to describe the purpose of domain controllers.
Understand what this is, what folder contains.
Describe the purpose of the global catalog.
You'll be able to describe the ads signing process and the importance of DNS and service records, or
as the real records.
In that process, you'll be able to explain the functions of the operations master and you'll be able
to describe operations, master, role and season.
So let's get started.
