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






4. 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.






5. 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.






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






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






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 ______ refers to the process of deleting outdated resource records on which time stamps have been placed.






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

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






27. 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






28. 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.






29. 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.






30. 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.

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






33. Scavenging can occur only when ______ is enabled.






34. 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.






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






36. 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.






37. 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.
