Your network contains an Active Directory forest.
The forest contains two domains named contoso.com and woodgrovebank.com.

You need to ensure that Attribute1 is replicated to the global catalog.
What should you do?
A. In Active Directory Sites and Services, configure the NTDS Settings.
B. In Active Directory Sites and Services, configure the universal group membership caching.
C. From the Active Directory Schema snap-in, modify the properties of the User class schema object.

The Global Catalog Server
The Global Catalog (GC) is an important component in Active Directory because it serves as the central information store of the Active Directory objects located in domains and forests. Because the GC maintains a list of the Active Directory objects in domains and forests without actually including all information on the objects and it is used when users search for Active Directory objects or for specific attributes of an object, the GC improves network performance and provides maximum accessibility to Active Directory objects.

How to Include Additional Attributes in the GC
The number of attributes in the GC affects GC replication. The more attributes the GC servers have to replicate, the more network traffic GC replication creates. Default attributes are included in the GC when Active Directory is first deployed. The Active Directory Schema snap-in can be used to add any additional attribute to the GC. Because the snap-in is by default not included in the Administrative Tools Menu, users have to add it to the MMC before it can be used to customize the GC.
To add the Active Directory Schema snap-in in the MMC:
1. Click Start, Run, and enter cmd in the Run dialog box. Press Enter.
2. Enter the following at the command prompt: regsvr32 schmmgmt.dll.
3. Click OK to acknowledge that the dll was successfully registered.
4. Click Start, Run, and enter mmc in the Run dialog box.
5. When the MMC opens, select Add/Remove Snap-in from the File menu.
6. In the Add/Remove Snap-in dialog box, click Add then add the Active Directory Schema snap-in from the Add Standalone Snap-in dialog box.
7. Close all open dialog boxes.
To include additional attributes in the GC:
1. Open the Active Directory Schema snap-in.
2. In the console tree, expand the Attributes container, right-click an attribute, and click Properties from the shortcut menu.
3. Additional attributes are added on the General tab.
4. Ensure that the Replicate this attribute to the Global Catalog checkbox is enabled.
5. Click OK.
