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






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






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






4. 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 ______.






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






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 ______ refers to the process of deleting outdated resource records on which time stamps have been placed.






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






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






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






10. 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.






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






12. 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






13. 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.






14. Scavenging can occur only when ______ is enabled.






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






16. 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.






17. 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






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






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






20. 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.






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






22. ______ 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.






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






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






25. The four options presented on the _____________________ are the following: 1. To All DNS Servers In This Forest 2. To All DNS Servers In This Domain 3. To All DCs In This Domain 4. To All DCs Specified In The Scope Of This Directory Partition






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






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. 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.






29. 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






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. 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: _______.






32. 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.






33. Increasing the refresh interval ______ zone transfer traffic.






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






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






36. 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.






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






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






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






40. 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.






41. 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.






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






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






44. 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.






45. 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.






46. 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.
