NetBIOS An API used in older Microsoft networks that allows computers to connect and communicate. Naming and name resolution are two of the many services NetBIOS offers. FQDN Fully qualified domain name. A DNS name that uniquely identifies a computer on the network. For example, an FQDN might be client1.microsoft.com. recursion The process of a DNS server querying other DNS servers to resolve a name on behalf of a DNS client. recursive query A client query that requests recursion from the server.
stub zone A copy of a zone containing only those resource records necessary to identify the authoritative DNS servers for the master zone.

Questions and Answers
Lesson 1, Practice
Page 4-9
1. Look at the protocols listed in the new network capture. In Network Monitor, NBT represents NetBT, and DNS represents Domain Name System. Based on the protocol you see in this capture and on the description pro vided for given frames, determine whether NetBIOS name resolution or DNS name resolution has been used to resolve the computer name Computer2. Why has this method been used and not the other method Write your answer in the space provided.
NetBIOS name resolution has been used because, although Windows Server 2003 networks use DNS name resolution when this service is available, no DNS server has been configured yet on this network. In such cases, Windows Server 2003 networks use the NetBT protocol and NetBIOS name resolution to resolve computer names to IP addresses.
Lesson 1 Review

1. The network you administer includes 10 computers running Windows Server 2003 and 200 computers running Microsoft Windows XP Professional. In the network, you have deployed a DNS server named DNS1 to host the zone lucernepublishing. com. You have also configured the zone to allow dynamic updates. A DHCP server is responsible for the IP configuration of all computers running Windows XP Professional. One of these computers, c1.lucernepublishing.com, can be con tacted only by IP address and not by name. Which of the following actions can you take to reregister this computer in DNS Choose all that apply. a. Execute the Nbtstat R command. b. Execute the Ipconfig /registerdns command. c. Shut down and restart c1.lucernepublishing.com. d. Execute the Nbtstat /registerdns command.
b, c
2. Which of the following is a legal NetBIOS computer name a. host1.microsoft.com b. host1_local c. host10_microsoft d. host1-microsoft

3. Which command can you use to purge the local NetBIOS name cache
Nbtstat R
Lesson 2 Review
Page 4-24
1. On the network you administer, you maintain a primary DNS server authoritative for the zone lucernepublishing.com. You have also deployed two caching-only servers that forward all requests to the primary server. If most of the name queries directed toward the caching-only servers are for names within the lucernepublishing.com domain, which parameter can you modify on the primary server to decrease DNS query traffic between the caching-only servers and the primary server
You can increase the TTL value of resource records at the zone level.
2. What is the root domain of a namespace containing the FQDN first.domain1.local. a. None. The namespace has no root domain. b. domain1. c. local. d. (empty string).
3. Which step does the resolver first perform to resolve a DNS name a. It checks its local cache. b. It reads from the Hosts file. c. It broadcasts the local subnet. d. It queries the local DNS server.
4. Your network computers are turned on for the first time after a power outage. When a DNS client first submits a recursive query to a local DNS server to resolve an Internet name for which the server is not authoritative, which step takes place first a. The DNS client resolves the name from its cache. b. The DNS server resolves the name from its cache. c. The DNS server forwards the recursive query to an upstream DNS server. d. The DNS server contacts root servers configured in the Cache.dns file.
