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. 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.






2. 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.






3. 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.






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






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






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






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






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






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






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






11. 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.






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






13. 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.






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






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. 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:






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






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






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. 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.






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. Scavenging can occur only when ______ is enabled.






23. 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






24. 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






25. 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.






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






27. 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.






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






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






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






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






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






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






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






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






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






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






38. Increasing the refresh interval ______ zone transfer traffic.






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






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






41. When you create a new zone - two types of records required for the zone are automatically created. List them.






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






43. 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.






44. 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.






45. 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






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






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






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






49. 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.
