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. 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






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






3. 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.






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






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






6. Scavenging can occur only when ______ is enabled.

14. 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.






15. The ___________________ dialog box enables you to modify two key settings related to aging and scavenging: 1. the no-refresh interval 2. and the refresh interval






16. 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.






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






18. 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.






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






20. 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.

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






25. 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






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






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






28. 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.
