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 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:






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






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






4. 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.






5. 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.






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






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

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






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






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

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






14. A ______ zone is similar to a secondary zone - but it contains only those resource records necessary to identify the authoritative DNS servers for the master zone.






15. 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.






16. 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.






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






18. 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.






19. 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






20. 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.

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






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






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






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






26. 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.






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






28. Scavenging can occur only when ______ is enabled.






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






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






31. 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.






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






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






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






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






36. 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






37. 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.

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






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






41. 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.






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






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