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. What kind of zones do not automatically perform time stamping on dynamically created resource records?






2. The value you configure in the ______ text box determines how long a secondary server waits before retrying a failed zone transfer. Normally - this time is less than the refresh interval. The default value is 10 minutes.






3. Win 7 clients can be configured to request DNSSEC through the Name Resolution Policy Table (NRPT) in ______.






4. DNSSEC enables a DNS server to ______ the resource records in its zones.






5. You can perform a delegation only from a ________________.






6. 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 ______.






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






8. Used to facilitate the resolution of single-label computer names in a large network.

11. The _____ option stores the zone in the domain partition. Every DC in the local domain will receive a copy of the zone - regardless of whether the DNS Server role is installed on that DC.

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






15. What is the name of the record that contains a hash of the public key in a delegated subdomain?






16. Public key cryptography provides ______ - which means that separate keys are used to encrypt and decrypt data.






17. 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.

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






20. 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.






21. 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.






22. 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.

27. To configure notifications - click ______ on the Zone Transfers tab when zone transfers are enabled.






28. Active Directory-integrated zones perform time stamping for dynamically registered records by default - even before aging and scavenging are enabled. However - primary standard zones place time stamps on dynamically registered records in the zone onl






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






30. The ______ option stores the new zone in the ForestDnsZones partition. Every DC in the entire forest and on which the DNS Server role is installed will receive a copy of the zone.






31. This operation performs a zone transfer from the secondary zone's master server regardless of the serial number in the secondary zone's SOA resource record.






32. Scavenging can occur only when ______ is enabled.






33. A secondary zone will not be recognized as a valid name server until it contains a valid copy of zone data. For the secondary zone to obtain this data - you must first ______ to that server.

36. 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.






37. The value you configure in the ______ text box determines the length of time that a secondary server - without any contact with its master server - continues to answer queries from DNS clients. After this time elapses - the data is considered unrelia






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






39. ______ zones provide a means to offload DNS query traffic in areas of the network where a zone is heavily queried and used.
