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 ______ 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.






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






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






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






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






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






7. The value you configure in the ______ text box determines the length of time that a secondary server - without any contact with its master server - continues to answer queries from DNS clients. After this time elapses - the data is considered unrelia






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






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






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






11. 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.






12. 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.






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






14. 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.






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






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






17. 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.






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






19. 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.






20. 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 ______.






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






22. 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.






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






25. 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






26. To ______ a zone is to create a new zone for a subdomain within a DNS namespace and relinquish authority of that new zone.






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






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






29. By right-clicking a secondary zone in the DNS Manager console tree - you can use the shortcut menu to perform the following secondary zone update operations:






30. 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






31. Increasing the refresh interval ______ zone transfer traffic.






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

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






36. 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.






37. ______ 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.






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






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






40. 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.
