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 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: _______.






2. 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






3. 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.






4. 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






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






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






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

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






12. 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.

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






15. 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.






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






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






18. 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.






19. Increasing the refresh interval ______ zone transfer traffic.






20. Scavenging can occur only when ______ is enabled.






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






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






23. 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






24. 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 ______.






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






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






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






28. 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 ______.






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






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






31. 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.






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






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






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






35. 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.






36. 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

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






40. 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.






41. 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.






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

44. 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.






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






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