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






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






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






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






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






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






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






9. 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.






10. 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 ______.






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






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






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 ______ refers to the process of deleting outdated resource records on which time stamps have been placed.






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






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






16. 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.






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






18. 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: _______.






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






20. 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






21. 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.






22. 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.






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






24. 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.






25. 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.






26. 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:






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






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






29. ______ 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.






30. 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.






31. 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.






32. 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.






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






34. 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.






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






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






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






38. The most common resource records you need to create manually include the following:
