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.

4. There are three basic steps in _______________: 1. Enable GlobalNames zone support. 2. Create the GlobalNames zone. 3. Populate the GlobalNames zone.






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






6. Increasing the refresh interval ______ zone transfer traffic.






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

12. 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.






13. 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.






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






15. 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.






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 ______ refers to the process of deleting outdated resource records on which time stamps have been placed.






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






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






20. 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.






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






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






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






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






25. 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.






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






27. 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.






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






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






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






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






32. 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 ______.






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

43. 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






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






45. 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.






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






47. 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.
