Explanation:

To create a DNS infrastructure for the network that would allow the client computers in each office to register DNS names within their respective offices and to ensure that the client computers must be able to resolve names for hosts in all offices, you need to create an Active Directory-integrated zone at the head office site

Active Directory Integrated zones, store their zone information within Active Directory instead of text files. This ensures that the client computers can resolve names for hosts in all offices. The advantages of this new type of zone included using Active Directory replication for zone transfers and allowing resource records to be added or modified on any domain controller running DNS. In other words, all Active Directory Integrated zones are always primary zones as they contain writable copies of the zone database.
