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






2. 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.






3. 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.






4. To enable GlobalNames zone support - At an elevated command prompt - type the following: ______.






5. 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.






6. By default - DCs include two application directory partitions reserved for DNS data: ______.






7. 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.






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






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






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






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






12. The most common resource records you need to create manually include the following:






13. ______ are public keys from other zones that are used to validate digitally signed records originating from those zones and from delegated subdomains that are also DNSSEC-compatible.






14. 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






15. 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.






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






17. 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






18. 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.






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






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






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






22. The first step in preparing a zone for DNSSEC is to back up the current zone data. To back up a zone - type the following command at an elevated command prompt: _______.

24. 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.

26. For a delegation to be implemented - the parent zone must contain a _____ and an _____ (called a glue record) pointing to each authoritative server of the delegated domain.






27. 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






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






29. The ______ partition is replicated among all DCs that are also DNS servers in a particular domain






30. 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.






31. 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.






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






33. What does the 10 refer to in the following example: _ldap._tcp SRV 0 0 389 dc1.lucernepublishing.com.SRV 10 0 389 dc2.lucernepublishing.com.
