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






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






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






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






5. 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.






6. 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.






7. 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.






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






9. 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.






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






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






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. 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.






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






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






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






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






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






20. 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.






21. 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.






22. ______ 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.






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






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






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






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






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






28. 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






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






30. 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






31. 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






32. 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: _______.






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






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






35. 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.






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






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






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






39. 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.






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

44. 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.






45. 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

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






48. 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.
