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






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






3. 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






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 ______ refers to the process of deleting outdated resource records on which time stamps have been placed.






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






7. Scavenging can occur only when ______ is enabled.






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






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






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






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






12. ______ 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.






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






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






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






16. 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.






17. 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.






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






19. 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.






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






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






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. 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.






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






25. 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 ______.






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






27. 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






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






29. 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.






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






31. 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.






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






33. 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.






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






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






36. 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.






37. 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.






38. 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: _______.






39. Used to facilitate the resolution of single-label computer names in a large network.






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






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






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






43. 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.






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






45. By right-clicking a secondary zone in the DNS Manager console tree - you can use the shortcut menu to perform the following secondary zone update operations:






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






47. The ______ service uses SRV records to locate DCs in a domain by searching the domain for the LDAP service.






48. 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.






49. 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
