Your network contains an Active Directory Domain Services (AD DS) forest named contoso.com. The root domain contains the domain controllers shown in the following table.
A failure of which domain controller will prevent you from creating application partitions?
In an Active Directory Domain Services (AD DS) forest, the Domain Naming Master FSMO role is crucial for creating application partitions. The domain naming master is the only domain controller that can add or remove domains in the forest and handle cross-references to domains in external directories. It also manages new instances of application directory partitions. A failure of the domain controller holding this role (in this case, DC1) would prevent the creation of application partitions or any changes to the domain namespace. Therefore, a failure of DC1 will prevent the creation of application partitions.
Initial replication and connectivity requirements This FSMO role holder is only active when the role owner has inbound replicated the configuration NC successfully since the Directory Service started. Domain members of the forest only contact the FSMO role holder when they update the cross-references. DCs contact the FSMO role holder when: Domains are added or removed in the forest. New instances of application directory partitions on DCs are added. For example, a DNS server has been enlisted for the default DNS application directory partitions. https://docs.microsoft.com/en-us/troubleshoot/windows-server/identity/fsmo-roles#domain%20naming

A is correct
A for answer as supported by link given Domain naming master FSMO role The domain naming master FSMO role holder is the DC responsible for making changes to the forest-wide domain name space of the directory, that is, the Partitions\Configuration naming context or LDAP://CN=Partitions, CN=Configuration, DC=<domain>. This DC is the only one that can add or remove a domain from the directory. It can also add or remove cross references to domains in external directories.

A. DC1
Answer: A, DC1 If DC1 were to fail, any operations requiring the Domain Naming Master role, including creating application partitions, would be impossible until either: - DC1 is restored to service, or - The Domain Naming Master role is transferred to another domain controller
DC4 (Schema Master) If DC4 (Schema Master) fails, you will not be able to create application partitions, as this FSMO role is responsible for managing schema updates, including those for application partitions.
