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. 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.






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






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






4. 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.






5. 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






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






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

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






11. 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






12. 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.






13. 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 ______.

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

20. Public key cryptography provides ______ - which means that separate keys are used to encrypt and decrypt data.






21. You use Group Policy to configure DNS clients to _________________.






22. 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.






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






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






25. 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.






26. 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.






27. The ______ allows you to specify the DNS query suffixes - prefixes - FQDNs - or reverse lookup subnets for which a Win 7 or Win Server 2008 R2 client will request DNSSEC.






28. 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.






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






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






31. Increasing the refresh interval ______ zone transfer traffic.






32. Win 7 clients can be configured to request DNSSEC through the Name Resolution Policy Table (NRPT) in ______.
