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






2. 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.






3. Increasing the refresh interval ______ zone transfer traffic.






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






5. What are the server requirements for storing a zone in AD?






6. 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.






7. When you do not store a zone in AD - the zone is called a ______ zone - and zone data is stored in text files on the DNS server.






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






9. The refresh interval is the time after the no-refresh interval during which time stamp refreshes are ______ and resource records are not scavenged. The default refresh interval is 7 days.






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






11. A ______ is a database containing records that associate names with addresses for a defined portion of a DNS namespace.






12. 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.

14. Scavenging can occur only when ______ is enabled.






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






16. 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.






17. TTL values are not relevant for resource records within their authoritative zones. Instead - the TTL refers to ______ in nonauthoritative servers. A DNS server that has cached a resource record from a previous query discards the record when that reco






18. To enable GlobalNames zone support - At an elevated command prompt - type the following: ______.

21. A ______ is a public key for a remote DNS server that is trusted and able to provide DNSSEC responses.






22. 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.
