MCTS: Configuring A DNS Zone Infrastructure

Instructions:
  • Answer 50 questions in 20 minutes. 2 minutes extra for reading the instructions.
  • 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 ______ is a public key for a remote DNS server that is trusted and able to provide DNSSEC responses.






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






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






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






5. Scavenging can occur only when ______ is enabled.






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






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






8. What kind of zones do not automatically perform time stamping on dynamically created resource records?






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






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






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






12. 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.






13. 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 ______.






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






15. 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.






16. You use Group Policy to configure DNS clients to _________________.






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






18. 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.






19. ______ 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.






20. 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.






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






22. 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






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






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 ______ refers to the process of deleting outdated resource records on which time stamps have been placed.






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






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






28. 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






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






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






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






32. 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.






33. 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.






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






35. 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






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






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






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






40. 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.






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






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






43. 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.






44. 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






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






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






47. 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.






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






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






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