MCTS: Configuring A DNS Zone Infrastructure

Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. The Zone Transfers tab also allows you to configure ______ to secondary servers whenever a change occurs at the primary zone.






2. The value you configure in the ______ text box determines how long a secondary DNS server waits before querying the master server for a zone renewal. The default value for this setting is 15 minutes.






3. To create a custom application directory partition - type the following command:






4. The no-refresh interval is the period after a time stamp during which a zone or server rejects a ______ refresh. The default no-refresh interval is 7 days.






5. Consequently - when aging is enabled - dynamically registered resource records can be scavenged after ___ days by default.






6. ______ in DNS refers to the process of using time stamps to track the age of dynamically registered resource records.






7. To enlist other DNS servers in the partition - type the following command:






8. Increasing the refresh interval ______ zone transfer traffic.






9. ______ resource records are used to specify the location of specific services in a domain.






10. The ______ option stores the new zone in the Domain-DnsZones partition. Every DC in the local domain and on which the DNS Server role is installed will receive a copy of the zone.

12. When you create a new zone - two types of records required for the zone are automatically created. List them.

18. When you create a new zone - two types of records required for the zone are automatically created: ______






19. The ______ service uses SRV records to locate DCs in a domain by searching the domain for the LDAP service.






20. This operation reloads the secondary zone from the local storage.






21. The ______ partition is replicated among all DCs that are also DNS servers in every domain in an AD forest.






22. Alias resource records are sometimes called canonical names (CNAME). These records allow you to ______ a single host.






23. The ______ option stores the zone in the user-created application directory partition specified in the associated drop-down list box.

26. To enable aging for a particular zone - you have to enable this feature both at the ______ level.






27. A ______ zone is similar to a secondary zone - but it contains only those resource records necessary to identify the authoritative DNS servers for the master zone.






28. If either of the default application directory partitions is deleted or damaged - you can re-create them in DNS Manager by right-clicking the server node and choosing ______.






29. DNS delegations are automatically used to separate ______ in a single forest.






30. You must be a member of the ______ group to create an application directory partition.






31. When the zone is stored in a file instead of AD - by default the primary zone file is named zone_name.dns - and this file is located in the ______ folder on the server.

34. There are three basic steps in _______________: 1. Enable GlobalNames zone support. 2. Create the GlobalNames zone. 3. Populate the GlobalNames zone.






35. A ______ zone provides original read-write source data that allows the local DNS server to answer DNS queries authoritatively about a portion of a DNS namespace.

37. The first step in preparing a zone for DNSSEC is to back up the current zone data. To back up a zone - type the following command at an elevated command prompt: _______.






38. A ______ is a data structure in AD that distinguishes data for different replication purposes.






39. In this way - digital signatures use ______ cryptography to prove that information is unspoofed and unchanged.






40. During this operation - the server hosting the local secondary zone determines whether the serial number in the secondary zone's SOA resource record has expired and then pulls a zone transfer from the master server.
