Your company just opened a small branch office where 10 computer users will work. You have installed a single Windows Server 2012 R2 computer configured as a member server for basic file and print server needs.

• An Active Directory–integrated zone hosting the zone in which the server is a member

• 1. A caching-only DNS server

You have a DNS server outside your corporate firewall that’s a stand-alone Windows Server 2012 R2 server. It hosts a primary zone for your public Internet domain name, which is different from your internal Active Directory domain names. You want one or more of your internal servers to be able to handle DNS queries for your public domain and to serve as a backup for the primary DNS server outside the firewall. Which configuration should you choose for internal DNS servers?

• 1. Configure a standard secondary zone.

• 1. Configure a standard stub zone.

• 1. Configure a forwarder to point to the primary DNS server.

• 1. Configure an Active Directory–integrated stub zone.

• DNS ServerA forwards a query to ForwarderB, which replies with a “not found” message. DNS ServerA continues the lookup by querying a root server. True or False?

• True

• False
