MCTS: Configuring A DNS Zone Infrastructure

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






2. 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






3. 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.






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






5. You must be a member of the ______ group to create an application directory partition.






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






7. 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.






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






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






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






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






12. 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.






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






14. Increasing the refresh interval ______ zone transfer traffic.






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

21. 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.






22. 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.






23. Scavenging can occur only when ______ is enabled.






24. 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.






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:

28. 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.






29. 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






30. 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






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.
