When an internal DNS server performs iterative queries on the Internet to resolve names, this process requires your internal network to be exposed to outside servers. Through forwarding, you can restrict cross-firewall DNS traffic to only two computers the internal forwarding DNS server and the DNS forwarder outside a firewall. With this arrangement, the external forwarder can perform iterative queries on behalf of internal servers without exposing the network.

3. You administer a network that consists of a single domain. On this network, you have configured a new DNS server named DNS1 to answer queries for Internet names from the local domain. However, although DNS1 is connected to the Internet, it continues to fail its recursive test on the Monitoring tab of the server properties dialog box. Which of the following could be the potential cause for the failure a. You have configured DNS1 in front of a firewall. b. DNS1 hosts a zone named . c. Your root hints have not been modified from the defaults. d. You have not configured DNS1 to forward any queries to upstream servers.

5. In the Domain1.local Properties dialog box, click the Start Of Authority (SOA) tab. Using the settings configured on this tab, answer the following questions in the spaces provided. According to the settings on the Start Of Authority (SOA) tab, if Computer2 loses contact with Computer1, how long will the DNS server on Computer2 continue to answer queries from DNS clients
One day
How often is Computer2 configured to query Computer1 to find out whether any changes have been made to the zone
Every 15 minutes
If Computer2 discovers it cannot contact Computer1 when it initiates an SOA query, how long does it wait before trying again
10 minutes
If another primary DNS server named dns.domain2.local successfully queries Computer1 for the IP address of Computer2, how long does Computer2 s A resource record stay alive in the cache of dns.domain2.local
1 hour
Lesson 2 Review

1. Describe the process by which secondary servers determine whether a zone trans fer should be initiated.
The secondary server conducts an SOA query, in which the serial number value in the primary zone s SOA resource record is compared to the serial number value in the secondary server s own version of the zone database. If the secondary server determines that the master zone has a higher serial number, a transfer is initiated.
2. What is the difference between IXFR and AXFR queries
IXFR queries initiate an incremental zone transfer. In these transfers, only the updated informa tion is transferred across the network. AXFR queries initiate an all zone transfer. In these trans fers, the complete zone database is transferred across the network.
3. You have multiple DHCP servers on your network, some of which are configured to register DNS records on behalf of pre-Windows 2000 clients. You have config ured DNS to allow only secure updates. However, you find that some DNS records are not being updated properly. How can you solve this problem
