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






3. 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






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






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






6. 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






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

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






10. 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.






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






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






13. Increasing the refresh interval ______ zone transfer traffic.






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






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






16. Scavenging can occur only when ______ is enabled.






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






18. 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






19. 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






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






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






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






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






24. 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.






25. The ______ option stores the new zone in the ForestDnsZones partition. Every DC in the entire forest and on which the DNS Server role is installed will receive a copy of the zone.

28. 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.

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






32. 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.






33. 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.






34. 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
