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 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.






2. 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.






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






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 ______ refers to the process of deleting outdated resource records on which time stamps have been placed.






5. 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.






6. Increasing the refresh interval ______ zone transfer traffic.






7. 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.






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






9. 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.






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






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






12. 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.






13. ______ 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.






14. 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.






15. 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.






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






17. 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.






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






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






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






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






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






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






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






25. 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






26. 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: _______.






27. 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.






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






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






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






31. The value you configure in the ______ text box determines the length of time that a secondary server - without any contact with its master server - continues to answer queries from DNS clients. After this time elapses - the data is considered unrelia






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






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






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






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






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






37. 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






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






39. If either of the default application directory partitions is deleted or damaged - you can re-create them in DNS Manager by right-clicking the server node and choosing ______.






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






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






42. 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.






43. 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.






44. 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.






45. 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






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






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






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