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. 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.






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






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






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






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






6. Increasing the refresh interval ______ zone transfer traffic.






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






8. 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.






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






10. To enable aging for a particular zone - you have to enable this feature both at the ______ level.






11. 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.






12. If either of the default application directory partitions is deleted or damaged - you can re-create them in DNS Manager by right-clicking the server node and choosing ______.






13. 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






14. To add an NS record - double-click any existing NS record in DNS Manager and add the server data to the ______ tab.






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






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






17. 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.






18. 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.






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






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






21. Scavenging can occur only when ______ is enabled.






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






23. 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.






24. A ______ is a database containing records that associate names with addresses for a defined portion of a DNS namespace.






25. 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.






26. 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: _______.






27. The refresh interval is the time after the no-refresh interval during which time stamp refreshes are ______ and resource records are not scavenged. The default refresh interval is 7 days.






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






29. 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.






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






31. 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.






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






33. 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.
