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. 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 ______.






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






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






5. 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






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






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






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






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

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






12. 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.






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






14. 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






15. 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.






16. 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.






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






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






19. 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.






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






21. 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






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






23. 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.






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






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






26. 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.






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






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






29. Increasing the refresh interval ______ zone transfer traffic.






30. 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.






31. 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 ______.
