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.

3. 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






4. Any of three events can ________________: When the refresh interval of the primary zone's SOA resource record expires - When a server hosting a secondary zone boots up - When a change occurs in the configuration of the primary zone and this primary






5. 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.






6. 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.






7. 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.






8. 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.






9. 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.






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






11. Scavenging can occur only when ______ is enabled.






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






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

15. 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.






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






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

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 ______ refers to the process of deleting outdated resource records on which time stamps have been placed.






22. 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






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.

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






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






27. 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.






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






29. 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.






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






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