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.

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






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






4. The four options presented on the _____________________ are the following: 1. To All DNS Servers In This Forest 2. To All DNS Servers In This Domain 3. To All DCs In This Domain 4. To All DCs Specified In The Scope Of This Directory Partition






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






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






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






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






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






10. 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.






11. 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. Increasing the refresh interval ______ zone transfer traffic.






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

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






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






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






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






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






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 ______ refers to the process of deleting outdated resource records on which time stamps have been placed.






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






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






30. 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.






31. 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 ______.






32. 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.






33. 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.






34. 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.






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






36. 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.






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






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






39. 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.






40. ______ 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.






41. 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.






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






43. 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.






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






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






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