Your network contains an Active Directory forest. The forest contains two domains named contoso.com and eu.contoso.com. All domain controllers are DNS servers. The domain controllers in contoso.com host the zone for contoso.com. The domain controllers in eu.contoso.com host the zone for eu.contoso.com. The DNS zone for contoso.com is configured as shown in the exhibit. (Click the Exhibit button.)
