HOTSPOT
Your network contains one Active Directory forest named contoso.com and one Active Directory forest named
adatum.com. Each forest contains a single domain.
You have the domain controllers configured as shown in the following table.
You perform the following three actions:
Create a user named User1 on DC3.
Create a file named File1.txt in the SYSVOL folder on DC1.
Create a Group Policy object (GPO) named GPO1 on DC1 and link GPO1 to Site2.
You need to identify on which domain controller or controllers each object is stored.
What should you identify? To answer, select the appropriate options in the answer area.
Hot Area:
Answer: 
Explanation:
* SYSVOL is simply a folder which resides on each and every domain controller within the domain. It contains
the domains public files that need to be accessed by clients and kept synchronised between domain controllers.
Here File1.text will be stored on both domain controllers in contoso.com (DC1 and DC2).
* User1 will be stored on both domain controllers in adatum.com (DC3 and DC4), and on the global catalog
server in contoso.com (DC1).
* The global catalog is the set of all objects in an Active Directory Domain Services (AD DS) forest. A global
catalog server is a domain controller that stores a full copy of all objects in the directory for its host domain and
a partial, read-only copy of all objects for all other domains in the forest. Global catalog servers respond to
global catalog queries.
GPO1 will be stored on the global catalog servers in the forest (Dc1 and DC3)

is there some trust between? 2 sepprate forest do not know anything about object sin another forest. so answer is wrong
Answers are wrong, there are 2 separate forests here. Even with a trust there would be no replication from the first forest to the second forest and/or domains.
check the discussion on this question on this page:
https://equizzing.com/microsoft/what-should-you-identify-100/
I would like to go for this answer:
File1. User1. GPO1
DC1 Y N Y
DC2 Y N N
DC3 N Y Y
DC4 N Y N
If I am wrong, please correct me, thanks:)
This one is confusing. But judging by the question we have 2 forest not one
“Your network contains ONE Active Directory FOREST named contoso.com AND ONE Active Directory FOREST named adatum.com.” It doesn’t say One Active directory forest with two domains.
Imo, how the servers are set in the sites it doesn’t really matter for what’s been asked here, this and the wording about the forest is for confusing us.
So I’m with Watcher:
F:File
U:User
G:GPO
— F-U-G
DC1 v _ v
DC2 v _ v
DC3 _ v _
DC4 _ v _
