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. 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






2. You use Group Policy to configure DNS clients to _________________.






3. The Zone Transfers tab also allows you to configure ______ to secondary servers whenever a change occurs at the primary zone.






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






5. 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.






6. 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.






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






8. 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.






9. 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






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






11. 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.






12. The GlobalNames zone is compatible only with DNS servers running ______. Therefore - it cannot replicate to servers running earlier versions of Windows Server.

14. The ______ partition is replicated among all DCs that are also DNS servers in a particular domain






15. To add an NS record - double-click any existing NS record in DNS Manager and add the server data to the ______ tab.






16. ______ are public keys from other zones that are used to validate digitally signed records originating from those zones and from delegated subdomains that are also DNSSEC-compatible.






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






18. DNSSEC in Win Server 2008 R2 allows a ______ to validate DNS data on behalf of its Win 7 clients.






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






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






21. To ______ a zone is to create a new zone for a subdomain within a DNS namespace and relinquish authority of that new zone.






22. 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.






23. 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.






24. Also recommended for use in the following scenarios: When a host specified in an A resource record in the same zone needs to be renamed - When a generic name for a well-known server such as www needs to resolve to a group of individual computers tha

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






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






28. Increasing the refresh interval ______ zone transfer traffic.






29. 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.






30. When scavenging is not enabled - you can perform manual scavenging in zones by right-clicking the server icon in the DNS Manager console tree and then choosing ______.






31. 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.

35. 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.






36. 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






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






38. 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.






39. 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.
