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 ______ 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.






2. The four options presented on the _____________________ are the following: 1. To All DNS Servers In This Forest 2. To All DNS Servers In This Domain 3. To All DCs In This Domain 4. To All DCs Specified In The Scope Of This Directory Partition






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






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






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






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






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






8. 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.






9. 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






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






11. DNSSEC in Win Server 2008 R2 allows a ______ to validate DNS data on behalf of its Win 7 clients.






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






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






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






15. 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






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






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






18. 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.






19. Scavenging can occur only when ______ is enabled.






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






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






22. 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






23. 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






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






25. 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.






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






27. Increasing the refresh interval ______ zone transfer traffic.






28. 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.






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






30. 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: _______.






31. 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.






32. 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 ______.






33. 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.






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






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






36. To create a custom application directory partition - type the following command:






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






38. 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.






39. 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.






40. 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.






41. 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.






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






43. 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






44. 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:






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






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