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.

2. ______ zones provide a means to offload DNS query traffic in areas of the network where a zone is heavily queried and used.






3. 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.






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






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






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

12. In this way - digital signatures use ______ cryptography to prove that information is unspoofed and unchanged.






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






14. You can perform a delegation only from a ________________.






15. 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.






16. 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

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






19. 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.






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






21. Increasing the refresh interval ______ zone transfer traffic.






22. 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






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






24. There are three basic steps in _______________: 1. Enable GlobalNames zone support. 2. Create the GlobalNames zone. 3. Populate the GlobalNames zone.






25. The Zone Transfers tab also allows you to configure ______ to secondary servers whenever a change occurs at the primary zone.






26. 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.






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






28. A ______ is a public key for a remote DNS server that is trusted and able to provide DNSSEC responses.






29. To configure notifications - click ______ on the Zone Transfers tab when zone transfers are enabled.






30. 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.






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






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






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






34. 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






35. 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.
