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






2. 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






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






4. 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.






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






6. 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






7. Scavenging can occur only when ______ is enabled.






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






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






10. The ___________________ dialog box enables you to modify two key settings related to aging and scavenging: 1. the no-refresh interval 2. and the refresh interval

12. By default - zone transfers are ______ from any zone.






13. The value you configure in the ______ text box determines the default Time to Live (TTL) that is applied to all resource records in the zone. The default value is one hour.






14. 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.






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






16. For a DC to fall within the scope of such a directory partition - you must ______ that DC in the partition.






17. 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

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






20. ______ refers to the process of deleting outdated resource records on which time stamps have been placed.






21. Manually created resource records for all zone types are assigned a time stamp of 0; this value indicates that they ______ be aged.






22. Any of three events can ________________: When the refresh interval of the primary zone's SOA resource record expires - When a server hosting a secondary zone boots up - When a change occurs in the configuration of the primary zone and this primary






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






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

29. For a delegation to be implemented - the parent zone must contain a _____ and an _____ (called a glue record) pointing to each authoritative server of the delegated domain.






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

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






36. 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. 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.
