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






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






3. ______ 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.






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






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






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






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






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






9. 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.






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






11. 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.






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






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






14. The value you configure in the ______ text box determines how long a secondary DNS server waits before querying the master server for a zone renewal. The default value for this setting is 15 minutes.






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






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






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






18. 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.






19. 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.






20. 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.






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






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






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






24. 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.






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






26. 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.






27. 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.






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






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






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






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






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






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






34. Scavenging can occur only when ______ is enabled.






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






36. The first step in preparing a zone for DNSSEC is to back up the current zone data. To back up a zone - type the following command at an elevated command prompt: _______.






37. 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.






38. 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 ______.






39. Increasing the refresh interval ______ zone transfer traffic.






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






41. 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.






42. 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.






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






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






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