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






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






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






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






6. 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.






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






8. 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.






9. 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.






10. What are the server requirements for storing a zone in AD?






11. 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.






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






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






14. 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.






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






16. 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.






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






18. To enlist other DNS servers in the partition - type the following command:






19. Together - aging and scavenging provide a mechanism to ______ resource records - which can accumulate in zone data over time. Both aging and scavenging are disabled by default.






20. 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






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






22. Used to facilitate the resolution of single-label computer names in a large network.






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 ______ refers to the process of deleting outdated resource records on which time stamps have been placed.






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






25. 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 ______.






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






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






28. 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: _______.






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






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






31. 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.






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






33. When you create a new zone - two types of records required for the zone are automatically created. List them.






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






35. Increasing the refresh interval ______ zone transfer traffic.






36. Also recommended for use in the following scenarios: When a host specified in an A resource record in the same zone needs to be renamed - When a generic name for a well-known server such as www needs to resolve to a group of individual computers tha






37. TTL values are not relevant for resource records within their authoritative zones. Instead - the TTL refers to ______ in nonauthoritative servers. A DNS server that has cached a resource record from a previous query discards the record when that reco






38. The value you configure in the ______ text box determines the default Time to Live (TTL) that is applied to all resource records in the zone. The default value is one hour.






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