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.

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






8. The ______ allows you to specify the DNS query suffixes - prefixes - FQDNs - or reverse lookup subnets for which a Win 7 or Win Server 2008 R2 client will request DNSSEC.






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






10. By default - DCs include two application directory partitions reserved for DNS data: ______.

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






17. Scavenging can occur only when ______ is enabled.






18. 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.






19. 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.






20. 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.






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






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






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






24. Together - aging and scavenging provide a mechanism to ______ resource records - which can accumulate in zone data over time. Both aging and scavenging are disabled by default.






25. 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






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






27. 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






28. 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.






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






30. 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.

44. 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.






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