2. Which of the following statements are correct for Active Directory Global Catalogs?
(Choose all that apply.)
a. The Global Catalog is the central repository of information about objects in a
tree or forest.
b. By default, a Global Catalog is created automatically on the first domain controller
in the first domain in the forest.
c. The Global Catalog is a list of definitions that determines the kinds of objects
and the type of information about those objects that can be stored in Active
Directory.
d. You can have only one Global Catalog server in each domain.
The correct answers are A and B. C is not correct because this statement describes the Active
Directory schema, not a Global Catalog. D is not correct because you can have multiple Global
Catalog servers in a domain.
3. Every object in Active Directory has a(n) _______________________________ that
uniquely identifies an object and contains sufficient information for a client to
retrieve the object from the Directory.
DN
4. A(n) _________________________________ is a 128-bit number that is assigned to
an object when it is created and is guaranteed to be unique.
GUID
5. What is the difference between a contiguous namespace and a disjointed
namespace? Give an example of each type of namespace.
In a contiguous namespace, the name of the child object in an object hierarchy always contains
the name of the parent domain. A tree is a contiguous namespace. In a disjointed namespace,
the names of a parent object and of a child of the same parent object are not directly related
to one another. A forest is a disjointed namespace.
Case Scenario Exercise Questions
Questions and Answers
1. Would you suggest a single domain or multiple domains for this organization?
Why?
You should suggest a single domain for the company. Because the company is relatively small
and is connected by a high-speed, dedicated link there is no real need to use separate domains
for the locations. Also, the company wants users to be able to log on anywhere in the company
without specifying a logon location, which requires a single domain. With two domains, users
would sometimes need to specify the domain to which they were logging on.
