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. 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.






2. You must be a member of the ______ group to create an application directory partition.






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






4. This operation reloads the secondary zone from the local storage.






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






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






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






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






9. 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






10. Scavenging can occur only when ______ is enabled.






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






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






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






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






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






16. 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.






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






18. 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






19. 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.






20. What does the 10 refer to in the following example: _ldap._tcp SRV 0 0 389 dc1.lucernepublishing.com.SRV 10 0 389 dc2.lucernepublishing.com.






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






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






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






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






25. 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.






26. When you create a new zone - two types of records required for the zone are automatically created: ______






27. 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.






28. 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






29. 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.






30. 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.






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






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






33. 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.






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






35. 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.






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






37. In this way - digital signatures use ______ cryptography to prove that information is unspoofed and unchanged.






38. ______ 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.






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






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






41. The source zones from which secondary zones acquire their info are called ______ - and the data copy procedures through which this info is regularly updated are called zone transfers.






42. ______ resource records are used to specify the location of specific services in a domain.






43. 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 ______.






44. 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






45. Increasing the refresh interval ______ zone transfer traffic.






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






47. 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.






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






49. 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.






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