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






2. 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.






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






4. 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 ______.






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






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






7. 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.






8. 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.






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






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






11. Increasing the refresh interval ______ zone transfer traffic.






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






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






14. 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






15. 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.






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






17. 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.






18. 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.






19. 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.






20. Scavenging can occur only when ______ is enabled.






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






22. 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.






23. 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.






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






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






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






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






28. 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.






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






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. 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.






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






33. 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:






34. The most common resource records you need to create manually include the following:






35. 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.






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






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 ___________________ dialog box enables you to modify two key settings related to aging and scavenging: 1. the no-refresh interval 2. and the refresh interval






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