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. 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






2. 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:






3. 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.






4. 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.






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






6. 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






7. 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.






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






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






10. 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.






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






12. Scavenging can occur only when ______ is enabled.






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






14. 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.






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






16. 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.






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






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






20. 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.






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






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






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






24. ______ 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.






25. 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.






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






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






28. 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.






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






30. Win 7 clients can be configured to request DNSSEC through the Name Resolution Policy Table (NRPT) in ______.






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






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






33. What does the 10 refer to in the following example: _ldap._tcp SRV 0 0 389 dc1.lucernepublishing.com.SRV 10 0 389 dc2.lucernepublishing.com.






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






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






36. 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.






37. 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 ______.






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






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






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






42. 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.






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